POWERTRAIN OVERVIEW

The 2014 RLX is powered by an all-new 3.5-liter Direct Injection SOHC
i-VTEC® V-6 engine that delivers more power and greater fuel efficiency than the previous RL. This is the first Acura production car to feature "Earth Dreams Technology," which is comprised of a next-generation set of technological advancements to the engine, which greatly enhance both driving performance and fuel efficiency.

Rated at 310 horsepower and 272 lb.-ft. of torque (SAE net), the V-6 powerplant in the RLX develops an additional 10 horsepower and 1 lb.-ft. of torque compared to the 3.7-liter engine equipped in the RL. For exceptional drivability, the RLX's new 3.5-liter engine produces in excess of 90 percent of its peak torque over a very broad range of engine speeds, from 2,000 rpm to 6,600 rpm. The expansive torque spread makes for decisive throttle response and abundant power always at the ready.

In spite of the peak horsepower increase, the new engine has impressive EPA- fuel economy ratings for a two-wheel-drive luxury sedan, with ratings of 20 mpg in the city and 31 mpg on the highway. The 3.5-liter engine meets the stringent ULEV-2 California Air Resources Board (CARB) emissions rating. No competitive vehicle offers a comparable combination of peak horsepower output and EPA fuel economy ratings.

BODY OVERVIEW

The RLX employs an advanced body design to aid dynamic performance, NVH, fuel efficiency and crash safety. The RLX cabin is wide but also extremely aerodynamic, allowing both a roomy interior and a quiet ride as air slips smoothly over the cabin's flush-mounted available acoustic glass and other drag- and turbulence-reducing design details. Beneath the vehicle is a sophisticated series of aerodynamic aids that further smooth airflow.

The 2014 RLX is larger than the previous RL model in several key exterior dimensions, including width, wheelbase, and front and rear track.  The wheelbase, at 112.2 inches, is two inches longer than the previous RL model, providing more rear passenger room and improving the ride quality in the process. At 74.4 inches wide, the RLX is also a substantial 1.7 inches wider than the previous RL model. Among its competitive set, the new RLX is longer and wider than the Audi A6, BMW 5 Series, Lexus GS series, and Mercedes-Benz E-Class.

Static and dynamic rigidity and rear lateral stiffness are significantly improved. To increase stiffness and rigidity in key areas without increasing weight, 55 percent of the RLX body in white is made from high-strength steel. Hot-stamped high-strength steel is used in key areas for enhanced safety collision performance, with the added benefit of anticipated high scores in narrow offset, side impact, and roof strength tests.

Extensive use of aluminum body components in key areas saves 76.1 pounds compared to traditional all-steel construction. The biggest weight savings for any single component comes from the use of an aluminum hood, which saves 19.6 pounds compared to a steel hood. The RLX doors utilize a patented new hybrid construction utilizing aluminum outer panels for lighter weight and steel inner panels for stiffness and crash safety. Altogether, they provide a combination of high stiffness and a weight reduction of 24.3 pounds compared to all-steel doors.

Engineers paid particular attention to reducing interior noise levels, a complicated process that extends to literally every aspect of the vehicle's design and engineering. To achieve a premium level of interior quietness, the RLX receives an unprecedented amount of acoustic material in key areas. Available laminated sound-insulating glass (in Technology grades and higher) for all four doors and windshield provides the RLX with premium-level interior quietness.

The 2014 RLX features the world's first Jewel Eye™ LED headlights, which offer outstanding light distribution and excellent down-the-road illumination performance and light characteristics. The RLX taillights utilize periphery LED illumination that is both effective and highly distinctive.

CHASSIS OVERVIEW

Featuring new technologies such as Precision All-Wheel Steer (P-AWS) and Agile Handling Assist, the 2014 RLX chassis delivers the most accurate and confident handling of any Acura sedan in history. The range of technologies allows the RLX to be quick and responsive in city driving, confident and controlled on the highway, a willing dance partner on winding roads, and precise and stable in higher speed driving.

The standard Precision All-Wheel Steer (P-AWS) system on the RLX continuously monitors and calculates the correct amount of independent rear-wheel steering (toe angle) necessary for driving conditions. As the industry's first independent rear-wheel toe control system, P-AWS allows for up to 2.0 degrees of negative or positive toe angle, giving each wheel a range of up to 4.0 degrees of adjustment. P-AWS uses an all-electric system that enables crisper lane changes, more nimble turning in sharp curves, and enhanced dynamic response at higher speeds.

In front, the RLX's new double-wishbone, lower double-joint front suspension with Amplitude Reactive Dampers significantly improves handling agility, driver confidence and security, and ride sophistication. In back, the RLX's multi-link rear suspension is optimized for a flat ride during cornering, confident turning capability, and a smooth ride in a variety of urban, highway and open road scenarios.

The Amplitude Reactive Dampers have two separate damping mechanisms: one that is tuned for maximum efficiency on smoother roads with small inputs; and the other that is tuned to handle large inputs such as rough roads, potholes, and sudden steering and braking actions. The result is a vehicle that remains composed and comfortable in a wide range of driving conditions.

A new high-output variable gear ratio belt-type Electric Power Steering (EPS) system is a first for Acura. The system provides agile performance in low-speed driving maneuvers such as at intersections, improved overall accuracy and road feel, and superb high-speed stability. A high-rigidity steering column with matching high-strength angular bearing contributes to reduce vibration and improved steering feel.

Available Adaptive Cruise Control (ACC) allows the driver to set a desired speed and a distance interval behind a vehicle detected ahead, allowing the use of cruise control in light traffic. This system is combined with a new Low-Speed Follow capability, which extends the automatic following capability when traffic slows below the set speed. If the vehicle detected ahead is in range of the system and comes to a stop, the RLX will also come to a stop. When the vehicle ahead moves forward, the vehicle icon on the multi-information display will start to blink. With a press of the RES/+/SET/– switch up or down, or with a press of the accelerator pedal, the RLX will resume the prior set speed.

The RLX's high-efficiency Vehicle Stability Assist™ (VSA®) enhances vehicle stability when cornering. If vehicle understeer or oversteer is detected, the system selectively reduces power and/or brakes individual wheels to help correct the condition and stabilize the vehicle.

Finally, the available Lane Keeping Assist System (LKAS) scans the road ahead to actively assist the driver in driving in the middle of a detected lane.

The RLX and RLX with Navigation grades feature 7-spoke 18x8J noise-reducing alloy wheels while the Technology, Krell Audio and Advance grades feature larger 19x8J noise-reducing alloy wheels. The special noise-reducing design lowers tire noise by 7-decibels across the audible frequency range.

INTERIOR OVERVIEW

The 2014 RLX interior is an all-new design that combines welcoming five–passenger comfort with by far the most luxury and technology ever offered in an Acura. In the front seat area, a design concept called "dual personal structure" divides the space into areas centered on the driver and front passenger, complimented by a wide center stack and console that is easily accessible to each person. High-end premium elements like a carefully stitched leather instrument panel cover, soft-touch materials, premium finishes and rich wood-grain accents combine with an intuitive new control layout to create a distinctive environment in tune with this luxury performance sedan's clearly defined sporting character.

Open the door with the standard Smart Entry system, and you'll find that passenger space has increased in key dimensions compared to the 2012 RL, with more shoulder room front and rear. Rear seat legroom has been increased a substantial 2.5-inches, moving the RLX to the head of its competitive set in tandem seating distance. Heated 12-way adjustable (8-way power plus 4-way power lumbar support) front seats are standard, offering all-day comfort along with abundant lateral support for aggressive driving.

Ventilated front seats and heated rear seats are standard in the Advance grade. Rich, luxurious stain-resistant Milano leather seating is standard in the RLX with Technology package and higher grades; the base grade has synthetic leather-trimmed seating. Three interior colors are available: including Graystone, Ebony, and Seacoast.

Standard tri-zone climate control ensures passenger comfort throughout the cabin. All grades have a large front-seat center console that offers 9.9 liters of internal storage space, and feature a padded armrest lid that slides fore and aft for greater comfort. The lid can open to the left or right, to make access simple for either the driver or front seat passenger. The glove box has a new electric release which can be locked via touch screen.

With the expanded range of standard and available technology features built into the RLX, substantial engineering effort was put into making each feature intuitive and easy-to-use. The focal point of the new instrument panel is a large, 8-inch color audio/information screen that provides a range of useful information and access to an array of customizable features. When equipped with a navigation system, the screen positioned in this same location combines audio/information and navigation functions.

A 7-inch color On Demand Multi-Use Display™ (ODMD) positioned within easy reach controls the audio system and many other features. The touchscreen eliminates many physical buttons, and is the key contributor to the clean, uncluttered look of the new RLX interior. Dynamic menus clearly display controls for each functional mode, reduce screen clutter and help make operation simple. Audio and touch feedback improves usability and control, and helps keep the driver's eyes on the road.

Acura is known for its technology leadership, and the 2014 RLX further expands on this concept. The RLX is equipped with the next-generation AcuraLink® cloud-based connected car system, delivering a comprehensive array of media, convenience, and security services via embedded two-way communications and web-enabled devices. AcuraLink® leverages Pandora® interface for streaming audio and the Aha™ by Harman cloud-based interface to provide users with thousands of customizable cloud-based news, information and media feeds. Next-generation AcuraLink® also delivers an array of available, subscription-based, security and convenience features, such as AcuraLink Real-Time Traffic™ featuring freeway traffic and, for the first time, surface street traffic information; airbag deployment notification; stolen vehicle tracking; remote locking and unlocking; security alarm notification; and 24-hour personalized concierge services.

The new generation of the system makes its debut in navigation-equipped trims of the 2014 Acura RLX, and will be available with three-tiers of service: the Standard Package, which is complimentary for three years, and the Connect and Premium Packages, which are subscriber-based services providing new levels of connectivity for the luxury customer.

Exceptional audio performance has long been an Acura hallmark, and in the RLX, the bar has been raised further still. Three audio systems are offered, starting out with an impressive Acura/ELS® 10-speaker sound system. In the RLX Technology grade, the Acura/ELS Studio® Premium Audio System is standard, with an advanced 14-speaker array.

The RLX is equipped with Acura's next-generation Advanced Compatibility Engineering™ II(ACE™ II) body structure, which uses interconnected front frame members designed to absorb and redirect crash energy around the passenger cabin in a frontal collision.

2014 Acura RLX - Powertrain

The 2014 RLX is powered by an all-new 3.5-liter Direct Injection SOHC i-VTEC® V-6 engine rated at 310 horsepower and 272 lb.-ft. of torque (SAE net). This is the first Acura production example of Honda's "Earth Dreams Technology," which is comprised of a next-generation set of technological advancements that greatly enhance both driving performance and fuel efficiency.

The powerplant in the RLX develops an additional 10 horsepower compared to the 3.7 liter engine in the previous RL. For exceptional drivability, the RLX's new 3.5-liter engine produces in excess of 90 percent of its peak torque figure over a very broad range of engine speed, from 2000 rpm to 6600 rpm. The expansive torque spread makes for quick throttle response and abundant power always at the ready.

In addition to the peak horsepower increase, the new direct-injection engine contributes to the RLX's top-class EPA fuel economy ratings of 20 mpg in the city and 31 mpg on the highway.  The RLX also meets the stringent ULEV-2 California Air Resources Board (CARB) emissions rating. No other vehicles in its competitive set offer a comparable combination of peak horsepower output and fuel economy ratings.

A broad array of Earth Dreams technology combines to enable the 3.5-liter engine's well-rounded performance. The RLX V-6 is the first Direct Injection (DI) Acura powerplant. Conventional engines using multi-port fuel injection mix fuel and air before they enter the combustion chamber. With direct injection, fuel is injected directly into each combustion chamber. This allows for better combustion and greater overall efficiency. The RLX engine also incorporates a range of advanced friction-reducing technologies that help boost fuel efficiency and power output. A new intake manifold design, special "tumble" type intake ports, new piston crown shapes, an elevated 11.5:1 compression ratio and a variable-flow exhaust system are keys to the high power output.

A new generation of i-VTEC® (intelligent Variable Valve Timing and Lift Electronic Control) for the intake valves is now combined with Variable Cylinder Management (VCM) that deactivates the rear bank of three cylinders for greater fuel efficiency when power demands are low. The VCM system can tailor the working displacement of the engine to match the driving requirements from moment to moment. During startup, aggressive acceleration or when climbing hills – when high power output is required – the engine operates on all six cylinders. During moderate speed cruising and at low or moderate engine loads, the system operates just the front bank of three cylinders. Since the system automatically closes both the intake and exhaust valves of the rear bank of three cylinders, pumping losses from air intake and exhaust are eliminated and fuel efficiency gets a further boost.

The 3.5L V-6 is teamed with a reengineered Sequential SportShift 6-speed automatic transmission that has a new, more intuitive selector mechanism and racing-inspired shift paddles located on the steering wheel. When in Drive, the transmission is fully automatic, while steering wheel-mounted paddles allow the driver to choose to command a quick gear change. With a press of the Sport mode button positioned near the shift gate, the driver can choose remapped, more aggressive automatic shift points and more pronounced engine braking during deceleration. In Sport mode, the paddle shifters can be used for full manual operation of the transmission for maximum control and driving engagement.

Compared to the 2012 RL, the RLX has a more aggressive final drive ratio to provide an increase in engine RPM and engine responsiveness at any given road speed. Grade Logic Control is paired with exclusive transmission shift programming to deliver responsive performance and a crisp driving feel.

To deliver precise handling performance and excellent all-season traction, the 2014 RLX with Precision All Wheel Steer has front wheel drive paired with Vehicle Stability Assist™ (VSA™) and traction control. In the near future, the RLX Sport Hybrid SH-AWD will join the model line, featuring an innovative new drive system that blends hybrid power with Acura's advanced Super-Handling All-Wheel Drive (SH-AWD). More information on the RLX Sport Hybrid SH-AWD will be provided prior to its on-sale date.

Engine Architecture

The RLX 3.5-liter VTEC® V-6 has a smooth-firing 60-degree V-angle and compact overall dimensions. The V-6 has a die-cast lightweight aluminum alloy block with cast-in-place iron cylinder liners. The first ever application of Direct Injection in an Acura vehicle combines with i-VTEC and Variable Cylinder Management (VCM) to give the RLX a potent blend of power and fuel efficiency. This clean-running engine meets ULEV-2 emissions standards applied in select states, and Federal Tier 2, Bin 5 standards.

A wide range of improvements, including revised intake and exhaust ports, and updated valve timing help make the 3.5-liter V-6 more powerful than the 3.7-liter engine it replaces. The aluminum-alloy 24-valve engine now produces 310 horsepower at 6,500 rpm (an increase of ten horsepower) and generates 272 lb-ft of torque at 4,500 rpm. Torque is markedly improved in the lower ranges, where the engine typically operates.

Along with the increased horsepower, the updated V-6 also contributes to a 20-percent increase in the EPA highway fuel economy rating, due in part to an efficient front wheel drive layout (the previous RL was offered only with SH-AWD) and internal friction reduction features, including an oil-ring ion-plating treatment, plateau honing and reduced auxiliary-belt tension. A new tumble-type intake port design improves combustion efficiency, and torque-converter function in the standard 6-speed automatic transmission has been refined. The RLX has an EPA-fuel economy rating of 20/31/241 mpg city/hwy/combined.

Engine Block and Crankshaft

With its 60-degree V-angle, the RLX's V-6 engine is inherently smooth and has compact overall dimensions that allow efficient packaging within the vehicle. The V-6 has a die-cast lightweight aluminum alloy block with cast-in-place iron cylinder liners. Made with a centrifugal spin-casting process, the thin-wall liners are high in strength and low in porosity. The block incorporates a deep-skirt design with four bolts per bearing cap for rigid crankshaft support and minimized noise and vibration. The 3.5L V-6 uses a high-strength steel crankshaft for minimum weight.

A new cooling control spacer positioned in the water jacket surrounding the cylinders helps to maintain consistent operating temperature. Plateau honing of the cylinder lining further lowers the friction level between the pistons and the cylinders by creating an ultra-smooth surface. This two-stage machining process uses two grinding processes instead of the more conventional single honing process. Plateau honing also enhances the long-term wear characteristics of the engine.

Pistons/Connecting Rods

Designed with special "cavity-shaped" crowns, the RLX pistons help maintain stable combustion and contribute to stratified-charge combustion. Ion-plated piston rings help reduce friction for greater operating efficiency. The compression ratio (relative to the RL's previous 3.7-liter) has risen from 11.2:1 to 11.5:1. Heavy-duty steel connecting rods are forged in one piece and then the crankshaft connecting rods are "crack separated" to create a lighter and stronger rod with an optimally fitted bearing cap.  

Cylinder Heads/ Valvetrain

Like other Acura V-6 powerplants, the RLX engine's 4-valve cylinder heads are a single-overhead-camshaft design, with the cams driven by the crankshaft via an automatically tensioned toothed belt. Made of low-pressure cast, low-porosity aluminum, each cylinder head incorporates a new "tumble port" design that improves combustion efficiency by creating a more homogeneous fuel-air mixture. An integrated exhaust manifold cast into each cylinder head reduces parts count, saves weight, improves flow and optimizes the location of the close-coupled catalyst.

i-VTEC with 2-Stage Variable Cylinder Management™ (VCM®)

The RLX SOHC V-6 includes a new generation of i-VTEC with Variable Cylinder Management (VCM). Advances to VCM technology make a large contribution to the RLX's EPA fuel economy rating of 20/31/241 mpg city/hwy/combined.

i-VTEC Valve Control System

The RLX V-6 engine combines Variable Cylinder Management (VCM) with Variable Valve Timing and Lift Electronic Control (VTEC), which changes the lift profile, timing and lift duration of the intake valves. A switching mechanism allows each cylinder to operate with low-rpm valve lift and duration or high-rpm lift and duration. The rear cylinder bank's valve gear can also leave all intake and exhaust valves closed to maximize fuel efficiency during cylinder deactivation.

The "intelligent" portion of the system is its ability to vary valve operation based on the driving situation and engine rpm. At low rpm, the VTEC intake valve timing and lift are optimized (low lift, short duration) for increased torque, which allows a wide range of 3-cylinder operation. As engine rpm builds past 5,000 rpm, the VTEC system transitions to a high-lift, long-duration intake cam profile for superior high-rpm engine power.

VCM Operation

To help improve the fuel efficiency of the RLX engine, a new variation of Acura's Variable Cylinder Management (VCM) is used. The VTEC system combines with Active Control engine Mounts (ACM) to allow the VCM system to operate with three cylinders in a wide range of situations to maximize fuel efficiency and lower emissions. When greater power is needed, the system switches seamlessly to 6-cylinder operation. With the strong power output of the Direct Injection RLX engine, a 4-cylinder operating mode (as used on the port fuel injected 2013 RDX) is not needed.

During startup, aggressive acceleration, or when climbing hills – any time high power output is required – the engine operates on all six cylinders. During moderate-speed cruising and at low or moderate engine loads, the system operates just the front bank of three cylinders.

The VCM system can tailor the working displacement of the engine to match the driving requirements from moment to moment. Since the system automatically closes both the intake and exhaust valves of the cylinders that are not used, pumping losses associated with intake and exhaust are eliminated and fuel efficiency gets a further boost. The system combines maximum performance and maximum fuel efficiency – two characteristics that don't typically coexist in conventional engines.

VCM deactivates specific cylinders by using the i-VTEC (intelligent Variable Valve-Timing and Lift Electronic Control) system to close the intake and exhaust valves while the Power Control Module (PCM) simultaneously cuts fuel to those cylinders. The spark plugs continue to fire in inactive cylinders to minimize plug temperature loss and prevent fouling induced from incomplete combustion during cylinder re-activation.

The system is electronically controlled, and uses special integrated spool valves in the cylinder heads. Based on commands from the system's electronic control unit, the spool valves selectively direct oil pressure to the rocker arms for specific cylinders. This oil pressure in turn drives synchronizing pistons that connect and disconnect the rocker arms.

The VCM system monitors throttle position, vehicle speed, engine speed, automatic-transmission gear selection and other factors to determine the correct cylinder activation scheme for the operating conditions. In addition, the system determines whether engine oil pressure is suitable for VCM switching and whether catalytic-converter temperature will remain in the proper range. To smooth the torque-induced jolt of activating or deactivating cylinders, the system adjusts ignition timing, drive-by-wire throttle position and turns the torque converter lock-up on and off. As a result, the transition between 3- and 6-cylinder operation is effectively unnoticeable to the driver.

Direct Injection System

Conventional engines using multi-port fuel injection mix fuel and air before they enter the combustion chamber. With direct injection, fuel is injected directly into each combustion chamber. This allows for better combustion and overall efficiency.

The RLX V-6 engine is the first application of direct injection for an Acura vehicle in the United States. The system features a compact, high-pressure, direct-injection pump that allows both high fuel flow and pulsation suppression, while variable pressure control optimizes injector operation. A multi-hole injector delivers fuel directly into each cylinder (not to the intake port, as in conventional port fuel injection designs).

The multi-hole injectors can create the ideal stoichiometric fuel/air mixture in the cylinders for good emissions control. Theoretically, a stoichiometric mixture has just enough air to completely burn the available fuel.
Based on the operating conditions, the direct-injection system alters its function for best performance. Upon cold engine startup, fuel is injected into the cylinders on the compression stroke. This creates a weak stratified charge effect that improves engine start-up and reduces exhaust emissions before normal operating temperature is reached.

Once the engine is fully warm for maximum power and fuel efficiency, fuel is injected during the intake stroke. This helps create a more homogeneous fuel/air mix in the cylinder that is aided by the high-tumble intake port design. This improves volumetric efficiency, and the cooling effect of the incoming fuel improves anti-knock performance.

Active Control Engine Mounts and Active Sound Control

A new, more powerful 28-volt Active Control Engine Mount system (ACM) is used to minimize the effects of engine vibration as the VCM system switches cylinders on and off. The 28-volt ACM is a key factor in the VCM's broad range of operation in the new RLX. Sensors alert the Electronic Control Unit (ECU) to direct ACM actuators positioned at the front and rear of the engine to cancel engine vibration. In the cabin of the RLX, an Active Sound Control system further reduces low frequency sound relating to the function of the VCM system. (See Interior section for more information.)

Drive-by-Wire Throttle System

The RLX doesn't use a conventional throttle cable, but instead has smart electronics that "connect" the throttle pedal to a throttle valve inside the throttle-body. The result is less underhood clutter and lower weight, as well as quicker and more accurate throttle actuation. Plus, specially programmed "gain" between the throttle pedal and engine offers improved drivability and optimized engine response to suit specific driving conditions.

Acura's Drive-by-Wire throttle system establishes the current driving conditions by monitoring throttle pedal position, throttle valve position, engine rpm and road speed. This information is used to define the throttle control sensitivity that gives the RLX's throttle pedal a predictable and responsive feel that meets driver expectations. There are two different throttle profiles available in the RLX. When the transmission is in "D" (Drive) the drive-by-wire system uses the normal profile. When the Sport mode is engaged by pressing the Sport button located near the shift lever, the system switches to a more aggressive throttle map to enhance responsiveness.

Direct Ignition and Detonation/Knock Control

The RLX's Power Control Module (PCM) monitors engine functions to determine the best ignition spark timing. An engine block-mounted acoustic detonation/knock sensor "listens" to the engine, and based on this input, the PCM can retard the ignition timing to prevent potentially damaging detonation. The 3.5L V-6 has an ignition coil unit for each cylinder that is positioned above each spark plug's access bore.

Close-Coupled Catalysts and Variable Flow Exhaust System

The exhaust manifolds of the 3.5L V-6 are cast directly into the aluminum cylinder heads to reduce weight, decrease parts count, and create more underhood space. The result of this casting design is that the two primary catalytic converters are positioned much closer to the combustion chambers. High-efficiency next-generation precious metal catalytic converters are mounted directly to the exhaust port of each cylinder head to enable extremely rapid converter "light-off" after the engine starts. A significant weight savings is realized by eliminating traditional exhaust manifolds.
Downstream of the close-coupled catalytic converters, a hydroformed 2-into-1 collector pipe carries exhaust gases to a secondary catalytic converter located under the passenger cabin floorboard. This high-flow secondary catalytic converter has a large inlet and outlet to enhance exhaust flow. To balance the engine's need for quiet operation at low rpm and higher flow at high rpm, the RLX's dual exhaust system incorporates a variable flow rate feature. Pressure-operated exhaust valves in each silencer are closed in normal operation, reducing exhaust noise by as much as 8 dB. When the driver demands more performance from the RLX, rising exhaust gas pressure opens both valves. The additional exhaust flow ads five horsepower to the engine's peak output.

Emissions Control

The 2014 RLX 3.5L V-6 engine meets the tough EPA Tier 2 – Bin 5 and CARB LEV II ULEV emissions standards, and is certified to this level of emissions performance for 120,000 miles.

A number of advanced technologies are factors in the emissions performance. The unique cylinder head-mounted close-coupled catalytic converters light off more quickly after engine start up, and a 32-bit RISC microprocessor within the powertrain control module (PCM) boosts computing power to improve the precision of spark and fuel delivery.

The RLX's V-6 engine features Programmed Fuel Injection (PGM-FI) that continually adjusts the fuel delivery to yield the best combination of power, low fuel consumption and low emissions. Multiple sensors constantly monitor critical engine operating parameters such as intake air temperature, ambient air pressure, throttle position, intake airflow volume, intake manifold pressure, coolant temperature, exhaust-to-air ratios, as well as the position of the crankshaft and the camshafts.

To further improve emissions compliance, the 3.5L V-6 makes use of an after-cat design exhaust gas recirculation (EGR) system that allows cleaner, cooler EGR gas to be fed back into the intake system. An EGR system, especially one that delivers a cleaner/cooler charge, reduces pumping loss for better fuel efficiency.

One-Touch Start System

To ensure consistent starting, the RLX has a one-touch start system that maintains starter engagement until the engine starts. Should the driver release the Start button before the engine starts, the system will start the vehicle. Simply push the Start button (with the fob in the vehicle) and the engine will automatically start up.

Noise & Vibration Control

With its 60-degree V-angle and compact, rigid and lightweight die-cast aluminum cylinder block assembly, the 3.5L V-6 powerplant is exceptionally smooth during operation. Other factors that help reduce engine noise and vibration are a rigid forged-steel crankshaft, die-cast accessory mounts, and a stiff cast-aluminum oil pan that reduces cylinder block flex.

100,000 Mile Tune-up Intervals

The RLX's 3.5L V-6 requires no scheduled maintenance for 100,000+/- miles or more, other than periodic inspections and normal fluid and filter replacements. The first tune-up includes water pump inspection, valve adjustment, replacement of the camshaft timing belt, and the installation of new spark plugs.

Maintenance Minder™ System

To eliminate unnecessary service stops while ensuring that the vehicle is properly maintained, the RLX has a Maintenance Minder™ system that continually monitors the vehicle's operating condition. When maintenance is required, the driver is alerted via a message on the Multi-Information Display (MID).

The Maintenance Minder™ system monitors operating conditions such as oil and coolant temperature along with engine speed to determine the proper service intervals. Depending on operating conditions, oil change intervals can be extended to a maximum of 10,000 miles, potentially sparing the owner considerable expenditures and inconvenience over the life of the vehicle. The owner-resettable system monitors all normal service parts and systems, including oil and filter, tire rotation, air-cleaner, automatic transmission fluid, spark plugs, timing belt, coolant, brake pads and more. To avoid driver distraction while the vehicle is being operated, maintenance alerts are presented on the MID when the ignition is first turned on.

Sequential Sportshift 6-Speed Automatic Transmission

To help maximize driver control, acceleration and fuel efficiency, the 2014 RLX is equipped with a 6-speed automatic transmission featuring Sequential SportShift with racing-inspired steering wheel mounted paddle shifters and two automatic shift modes.
 
The Sequential SportShift 6-speed automatic offers excellent launch-feel, acceleration performance and fuel efficiency. Compared to the 2012 RL, the RLX has a more aggressive final drive ratio – 14-percent lower – to provide an increase in engine RPM and engine responsiveness at any given road speed.

The 6-speed transmission can be controlled by a straight-gate console-mounted shifter or via a steering wheel paddle shifter system that works whenever the transmission is in either of its two automatic modes. In addition to Grade Logic Control, Shift Hold control and Cornering G Shift control, the RLX adds a Sport mode button for increased driver involvement. All of the transmission logic systems work together to automatically alter shift timing based on driving conditions.

Automatic Modes

The Sequential SportShift 6-speed transmission can be operated in two different fully automatic modes with the console-mounted straight-gate shifter. The D (or "Drive") mode is ideal for most driving situations, and combines fuel efficiency with smooth operation and responsive power when needed. The Sport mode is for more performance-oriented driving, and features more aggressive shift mapping to keep engine rpm higher for greater acceleration and response.

When in the D mode (that is optimized for normal driving), the transmission incorporates an advanced Grade Logic Control System, Shift Hold Control and Cornering G Shift Control— all of which reduce unwanted shifting and gear hunting. The result is smart transmission operation that optimizes fuel efficiency and keeps the transmission in the appropriate gear for the specific driving conditions, thus generating excellent performance and smooth operation.

While traveling up or down hills, Grade Logic Control alters the transmission's shift schedule to reduce shift frequency and improve speed control. A shift map in the transmission computer continually measures throttle position, vehicle speed and acceleration/deceleration, and then determines when the vehicle is on a hill. The shift schedule is then adjusted to hold the transmission in lower gears to boost climbing power or to provide engine braking when traveling downhill.

Shift Hold Control keeps the transmission in its current (lower) gear ratio when aggressive driving is detected, as in the case of decelerating at a corner entry. Shift Hold Control leaves the chassis undisturbed by excess shifting and ensures that power will be immediately available (without a downshift) at the corner exit. Cornering G Shift Control monitors the speed of each rear wheel independently to determine when the RLX is turning. When the system detects a sufficient speed differential between the rear wheels, it will suppress any unwanted upshifts. This prevents the transmission from upshifting during a corner, which could upset the chassis balance thus requiring downshifting again at the corner exit when the throttle is applied.

Temporary Manual Operation in "Drive"

Whether in Drive or Sport mode, special transmission logic programming allows the use of the steering-wheel-mounted paddle shifters. When the driver operates the steering wheel-mounted paddle shifters while in Drive, the transmission responds to the driver's shift command and then returns to its normal fully automatic mode if further paddle shift inputs are not made within a given time. This special logic makes it easy for the driver to command a quick downshift without leaving the comfort of Drive mode. When in Sport mode, use of the paddle shifters puts the transmission into full manual mode that remains until another mode of operation is selected with the console-mounted shifter.

Manual Mode

By pressing the "Sport" button located next to the shift lever, Sport mode is engaged. This mode offers automatic operation with more aggressive shift mapping. A pull on the racing-inspired paddle shifters (mounted on the steering wheel) places the transmission in fully manual mode. A digital display in the instrument cluster indicates which gear the transmission is in. The system reverts to normal fully automatic mode if further paddle shift inputs are not made within a given time.

A double-kick-down feature lets the driver command a sport-minded double downshift— such as from Fifth to Third gear. By pulling on the left downshift paddle twice in rapid succession, the transmission will drop directly to the chosen lower gear ratio. The Drive-by-Wire™ throttle system also creates a "blip" of the throttle to help match gear speeds while downshifting.

To prevent harm to the powertrain when the transmission is paddle shifted by the driver (including during double-kick-down shifts), the system will inhibit potentially damaging shifts. As an added measure, the Powertrain Control Module (PCM) can also cut off engine fuel flow to prevent over-revving. If fuel cut-off is insufficient to prevent engine over-revving, as may be possible when the vehicle is on a steep downhill, the transmission will automatically upshift to prevent damage. On downshifts, the transmission will not execute a driver command that will over-rev the engine.

For improved stop-and-go performance and to help prevent "lugging" the engine, the Sequential SportShift transmission will automatically downshift to First gear when the transmission has been left in a higher gear (other than second) as the vehicle comes to a stop. In Manual Mode, when coming to a stop in second gear, the vehicle will start in second gear as well.

Multi-Clutch Lock-Up Torque Converter

The Sequential SportShift 6-speed automatic transmission is teamed with a special torque converter that has a high maximum torque rating and a unique converter lock-up assembly. The lock-up assembly uses multiple lock-up disks to reduce heat build-up during operation and for lock-up activation over a wide range of driving conditions that helps improve fuel economy.

Straight-Gate Shifter Assembly and Sport Mode

The straight-gate shifter is an intuitive and easy-to-use design that takes up little space in the center console. The shifter allows the driver to choose P (Park), R (Reverse), N (Neutral), or D (Drive, using First through Sixth gears). A separate button just behind the shift lever activates the performance-oriented Sport mode, with a more aggressive drive-by-wire profile and more performance-oriented shift programming. Sport mode also alters the performance of the Electric Power Steering (EPS).  

Cooperative Control Between Transmission and Drive-By-Wire

Both shift performance and smoothness are improved by cooperative control between the Drive-by-Wire throttle system and the electronically-controlled, Sequential SportShift 6-speed automatic transmission. The engine is throttled by the engine management system during upshifts and downshifts; thus the function of the engine and transmission can be closely choreographed for faster, smoother shifting. As a result, the peak g-forces (or "shift shock") are reduced significantly during upshifts and downshifts.

2014 Acura RLX - Body

Design Concept

Bristling with technological advances in lighting, aerodynamics and construction, the 2014 RLX body has the technology to match its athletic and sophisticated design. Lightweight and aerodynamic, the body provides outstanding collision protection, confidence-inspiring high speed stability, and exceptional fuel efficiency.

The RLX's dynamic body design combines a sleek overall shape, "aero-fused" cabin silhouette, and close tolerances for the wheel wells and body-panel gaps for a high degree of elegance and aerodynamics. The styling begins with a dynamic front-end featuring the RLX's signature Jewel Eye™ LED headlights, a substantial presence that imparts a look of power and confidence, while also proving highly aerodynamically efficient, providing powerful down the road illumination and even encompassing advanced pedestrian safety features.

Decisive character lines start alongside the hood, sweep over the front wheel arches, and then along the body sides. The body sides feature decisive character lines that subtly rise along the lower body sides, dramatically changing the light reflections and creating an especially dynamic visual signature for the RLX.

This athletic and sophisticated look is complemented by a flowing, aerodynamically sleek cabin design. Referred to by Acura designers as an "aero fused shape," the cabin is wide but also extremely aerodynamic, allowing both a roomy interior and a quiet ride quality as air slips smoothly over the cabin's flush-mounted available acoustic glass and other drag- and turbulence-reducing design details.

The wheel-arch hems use a much smaller gap to the tire than on the RL – and also a much smaller gap than is typical for the segment. This results in a more poised, integrated and finished look for the RLX side profile. The wheel-arch hems are also beautifully finished, adding to the sense of quality. Likewise, the hood, door and trunk-panel gaps are carefully controlled, with the aggregate effect that the RLX is immensely well crafted.

Beneath the vehicle is a sophisticated series of aerodynamic aids that further smooth airflow. These include an engine undercover, left and right floor covers, left and right mid under covers, and a rear under cover.

The rear of the RLX body is also dynamic, and here the cabin is noticeably wider than either of the outgoing RL or the RLX's primary competitors, lending a look of solidity. Due to the wider overall width and wider track, trunk space is also significantly enhanced compared to the outgoing RL model.

Seven different exterior colors, including four metallics and three pearl colors, are designed to complement the exterior shape and the way light defines it. New exterior badging includes the Acura marque and RLX and P-AWS emblems.

The RLX utilizes numerous aluminum components to lower the overall vehicle mass by 76 pounds, which helps to improve acceleration, steering and handling response, road-holding, braking performance, fuel efficiency, emissions, and crash safety. Aluminum components include the front and rear bumper beams, front fenders, hood, steering column mounting beam, floor pan, and door skins.

Among its competitive set, the new RLX is longer and wider than the Audi A6, BMW 5 Series, Lexus GS series, and Mercedes-Benz E-Class.

Competitor Summary

The chart below summarizes the RLX's exterior dimensions compared to key competitors.

Waiting Status

When parked and locked, the folding exterior mirrors retract, the security alarm system is armed, and the RLX goes into standby mode, waiting for its owner to return. Then when the driver (in possession of the key fob) approaches the vehicle, it unlocks the driver's door (or all doors if so programmed). When the driver opens the door to be seated, the RLX adjusts the seat and steering column to the preset positions, actives the instrumentation and sets the other features such as climate-control and audio-system presents to match the driver.

Body Rigidity

Static and dynamic rigidity and rear lateral stiffness are all improved. Bending rigidity is up 52 percent and torsional rigidity is up 46 percent compared to the previous RL model. In addition, rear lateral stiffness and the torsional rigidity of the rear upper damper mounting points are up 82 percent and 51 percent, respectively, compared to the previous RL.

High-Strength Steel

To increase stiffness and rigidity in key areas without increasing weight, 55 percent of the RLX body is made from high-strength steel, including the strategic use of ultra-high strength "hot stamped" 1500Mpa steel

The percentages of different steel grades used in the RLX body include:

Hot Stamped Steel

Ultra-high strength "hot stamped" 1500 Mpa steel is used in key areas for enhanced safety collision performance, particularly in narrow offset, side impact and roof strength tests. The hot-stamp steel is used in these areas:

• Side sills
• Side roof
• A pillar and roof edge to C pillar
• B pillar

Aluminum Body Components

Extensive use of aluminum in key areas saves 76.1 pounds compared to traditional all-steel construction, providing high strength with light weight that directly benefits ride, handling, fuel efficiency, emissions reductions and safety. The biggest weight savings from a single component comes from the use of an aluminum hood, which saves 19.6 pounds compared to a steel hood. Aluminum body components include:

• Hood
• Front bumper beam
• Front fenders
• Floor tunnel bar
• Rear bumper beam
• Steering-column hangar beam
• Front door skin
• Rear door skin

Aluminum Hybrid Construction Door
The RLX doors are a hybrid construction utilizing aluminum outer panels for lighter weight and steel inner panels for stiffness and crash safety. Together, they provide for increased stiffness with a weight reduction of 24.3 pounds compared to all-steel doors.

The front doors are constructed of four parts, while the rear doors are constructed of five parts. The steel inner panel uses a special high-corrosion-protection zinc, aluminum and magnesium plating – 11 percent aluminum, 3 percent magnesium and 86 percent zinc – to assure that electrolytic corrosion does not occur between the two metals. This plating gives the steel inner panel 10 times the resistance of traditional zinc galvanized plating.

The outer aluminum skin and steel inside panels are joined with an Acura-first "curl forming" process for high-strength and durability.

Class-Leading Aerodynamics

More than 800 wind-tunnel tests were conducted to improve vehicle aerodynamics values. As a result, the new RLX will have class-leading lower coefficient of lift (CL) and lower coefficient of drag (Cd).

Sound Insulation

Engineers paid particular attention to reducing interior noise, an effort that extends to literally every aspect of the vehicle's design and engineering – from aerodynamics and powertrain engineering to insulators and the selection of finishing materials – all play a part in the RLX's improved interior quietness.

To achieve a premium level of interior quietness, the RLX receives an unprecedented amount of acoustic material in key areas. The list includes:

• Carpet back surface
• Inside front/rear door lining
• Inside A-pillars
• Inside C-pillars
• Roof area behind moonroof opening
• Floor sills
• Inside trunk lid
• Rear deck
• Rear bulkhead
• Rear wheel wells

Acoustic Door Glass

The RLX with Technology package and higher grades use laminated, sound-insulating acoustic glass for all door glass, providing an extra measure of wind and road noise attenuation. The glass is 4.7mm thick and includes an acoustic membrane that helps attenuate frequencies above 1,600 Hz, resulting in an improvement of up to 14.7 dB over the previous model's 5mm thick tempered door glass.

Jewel Eye™ Headlights

The 2014 RLX features the world's first Jewel Eye™ LED headlights, which utilize a dual-stacked array of high-intensity LED lamps to deliver outstanding light distribution, and class-leading distant irradiation performance and light characteristics with a wavelength close to the human eye's luminosity curve. With two rows of five "Jewel Eye" lights per headlight, the LED lights provide improved down the road visibility compared to HID and halogen headlights.

On each side of the RLX, the low beams consist of four LED lights, while the innermost high beams utilize a pair of larger LED lights. The daytime running light (DRL) function is shared by the low-beam lenses, with the eight individual lenses clearly and dramatically visible even in bright sunlight. Altogether, they create a dramatic and distinctive appearance with superior lighting capability.

Each pair of low beam lenses irradiates a different area of the road as follows:

Light distribution
Both the low and separate high beam LED headlights offer outstanding performance in all nighttime driving conditions, including highway, winding roads, intersections, and in inclement weather conditions. The result is that the driver can see further with uniformity, making high-speed nighttime driving easier and less fatiguing.

A summary of LED benefits include:

• Outstanding light distribution that surpasses competitors
• Excellent distant illumination performance
• Clear illumination of the road surface and white lines
• High visibility of the entire visible color spectrum (white, red, green, blue and yellow) compared to HID and halogen headlights
• Response time when switching between low and high beam is shortened
• Light congruity is improved between low and high beams

When the lights are off, sunlight enters the display through the top of the lens, reflects off the rear reflector and then forward and through the lens again. As a result when lighting is off, the array still appears to be shining.

Power savings
Using just 68 watts total, the RLX's LED headlights use 40-percent less power than traditional halogen headlights, contributing to the RLX's overall operating efficiency. The comparison includes:

Long lasting
Besides producing better light characteristics with lower energy usage, the RLX's new LED headlights are longer lasting. With an estimated life expectancy of 10,000 hours, the LED headlights are projected to last five times longer than HID headlights and 10 times longer than traditional halogen headlight bulbs.  Further, their compact packaging allow for an improved aerodynamic frontal design.

LED Taillights

Another Acura first, the RLX taillights utilize periphery LED illumination that is both effective and highly distinctive. The taillight array consists of two semi-circular LED rings sweeping across the rear fender edges and the sides of the trunk lid. The light path combines functions of both the taillights and the side marker lights in one array. This LED array matches the "Jewel Eye" headlights for elegance and clearly distinguishes the RLX from every other vehicle on the road – even at a distance and especially at night. It also compliments the RLX body design.

LED taillight components include the LED assembly, a housing/reflector and inner and outer lenses. Uniform illumination is provided by a combination of by light diffusion, the specially grained finish of both an inner lens and a reflecting surface. Inside the periphery LED taillight array is a separate lighting array consisting of the stoplights and turn signals. Backup lights are located on the trunk lid, inside the perimeter taillight array.

One-Touch Turn Signals

The RLX's one-touch turn signals provide increased convenience for the driver when making routine lane changes. With the one-touch turn signal system, a quick movement of the turn-signal lever (between 0.4 sec. and 1 sec.) provides three blinks of the turn signals – an ideal scenario for changing lanes. Holding the lever for 1 sec. or longer (past the "click point") provides continuous blinking, such as for signaling a turn or exiting a thoroughfare.

Retracting Mirrors

At the driver's preference, the RLX's door mirrors on some grades can be configured to automatically retract when the doors are locked, and then automatically extend when the doors are unlocked. This automatic mirror retract/extend function helps safeguard the mirrors when the RLX is parked, while also creating a higher-quality experience for the driver by eliminating the need to remember to manually retract or extend the mirrors.

On all models, except for the RLX and RLX with Navigation grades, the mirrors automatically retract or extend in two ways: 1) simply press the lock/unlock button on the remote key fob; or 2) press the lock button on the door handle.  

The mirrors can also be retracted and extended by using the mirror switch on the driver's door panel. These functions can be customized through the MID on the instrument panel.

Expanded View Driver's Mirror

The 2014 RLX's Expanded View Driver's Mirror is integrated into the driver's side mirror. Standard equipment on all trim levels, the mirror increases the driver's field of vision by 6.5-degrees to provide a better view of objects that would otherwise be hidden in the vehicle's blind spot. This allows the driver to better recognize vehicles that are in their blind zone.

The major part of the mirror is flat and provides 15.1-degrees of visibility. Adding the 6.5-degrees of the Expanded View Driver's Mirror yields 21.6-degrees of visibility. In addition, the expansion of the view area gradually changes between flat and convex for a more natural user experience.

Intelligent Wipers

Laws in some states require drivers to turn on the headlights when the wipers are operating in the rain. The new RLX helps its driver comply with these laws by automatically illuminating the headlights when the wipers are activated in rainy conditions (with headlight switch in Auto). Operation is shown via an indicator on the instrument panel. If rain is intermittent, the lights stay on for a predetermined interval before automatically turning off again.

Wiper operation is equally advanced for maximum wiping area, better wiping quality, reduced weight, improved appearance and longer blade life. Details include:

• Wiper coverage is maximized by controlling the wiper position, including to the outer corners of the windshield.
• Wiper performance is maximized by adjusting the wiper speed according to road speed and wind pressure.
• The wiper motor uses a built-in ECU, reducing complexity compared to the RL wiper mechanism. The new RLX wiper motor assembly saves 4.6 pounds in comparison.
• For better appearance, the wipers are hidden under the hood when not in operation.
• For extended life of the wiper blades' rubber, the operating system periodically raises the wiper blades from underneath the hood (when not in use) to prevent blade deformation.

Self-Opening Trunk

The RLX trunk has a self-opening feature that fully opens the trunk lid. There are three ways to open the trunk: 1) by pressing the trunk opener switch located on the driver side door panel, 2) with the key fob and 3) with the trunk opener switch located in the middle of the trunk, underneath the trunk lid garnish. This makes it easier for the RLX driver to carry items and open the trunk lid at the same time. In contrast, the previous RL model, the trunk lid would open halfway compared to the RLX's fully open function. The trunk lid closes manually.

Trunk Storage

The RLX, RLX with Navigation, and RLX with Technology package offer 15.3 cu. ft. of cargo volume. The Krell Audio and Advance grades have 15.1 cu. ft. of cargo volume (all measurements include the tool kit and the puncture repair kit). The trunk features a flat floor design that extends from the bumper to the rear seatback for improved usability. Below the floor panel is a pair of useful covered storage wells.

Multi-Angle Rearview Camera

The RLX's standard multi-angle rearview camera features three viewing angles – Wide view, Normal view and Top Down view. Drivers may select the preferred view according to driving conditions.

An Acura first, the rearview camera system also features new dynamic guidelines that display the vehicle's backward trajectory according to steering-wheel position. When the steering wheel is straight, a broad 180-degree rearward view can be seen in Wide View, and Normal and Top Down views are also available. However when the steering wheel is turned 90 degrees, only Wide and Normal views are available, and dynamic guidelines curve onscreen to show the path of the vehicle. The result is improved convenience for the driver as the rearward trajectory of the RLX is indicated by the dynamic guidelines.

Rear Wheel Arch Hem

The RLX's sleek exterior design is enhanced by close tolerances between the tires and the wheel arches. Specially designed wheel-arch hems reduce the gap to just 46 mm between the top of the tire and the lower part of the wheel arch, 10.5-mm narrower than that of the previous RL model. As a result, the tires better fill the wheel wells for a greater sense of unity and substance.

Exterior Colors

The 2014 RLX is available in seven exterior colors, including four metallic and three pearl colors. All colors have a strong character, offering expressive contrasts that compliment the RLX's body-panel curves and angles, while also exhibiting a smart luxury appearance. The acid-resistant epoxy clear-coat paint is superior to typical clear-coat paints for increased resistance to urban pollutants.

Precision All-Wheel Steer™ (P-AWS) and Agile Handling Assist

A first for Acura, the combination of new Precision All-Wheel Steer™ (P-AWS) and Agile Handling Assist help the RLX driver smoothly and easily trace the desired line with smaller steering-wheel inputs. The result is improved dynamic performance in all driving conditions and helps RLX perform at the will of the driver. Precision All-Wheel Steer (P-AWS) and Agile Handling Assist are standard on all two-wheel-drive RLX models.

Precision All-Wheel Steer™ (P-AWS)
Precision All-Wheel Steer is the world's first all-electric left/right independent rear-wheel toe angle control system. Benefits of the system include:

• Minimized turning radius with neater execution of sharp low-speed turns
• Improved response for quick steering maneuvers such as lane changes
• Enhanced agility and nimbleness at roundabouts and intersections
• More confidence and control on curved highway on- and off-ramps
• Greater agility on winding roads
• Quicker and more effective emergency steering response
• Increased straight-line highway stability
• Confident braking stability
• Improved high speed response and stability in winter driving and when Vehicle Stability Assist (VSA) is activated

System Operation
Key components of  P-AWS include independent electrically assisted left/right actuators, special control arms and suspension uprights, and an electronic control unit that is linked via a dedicated Control Area Network (CAN) to the Electric Power Steering (EPS), Vehicle Stability Assist (VSA), braking and engine control systems.

In operation, P-AWS continuously monitors and calculates the correct amount of rear-toe angle input necessary for conditions, analyzing steering input, engine and road speed, transmission, throttle position, brake pressure, yaw rate, lateral acceleration and other factors. The maximum amount of rear-wheel toe angle adjustment is 2.0-degrees in either direction (positive or negative) for a total range of 4.0 degrees.

There are four fully automatic levels of P-AWS system operation to match such driving situations such as turning at an intersection, driving on windy roads, when merging or exiting a highway, higher speed maneuvers or in snowy conditions. The P-AWS system provides confidence-building cornering capability through improved responsiveness and vehicle control.
Examples include:

• When the driver initiates a lane-change maneuver requiring that the RLX neatly move into the next lane, the P-AWS system adjusts the rear wheel toe angles in phase (the same direction) with the front wheels enabling quick, clean maneuvering.
• For sharp low-speed turns, such as on city streets or in parking lots, the P-AWS system adjusts the rear wheels toe angles out of phase (the opposite direction) with the front wheels. This results in a tighter turning radius.
• When tracing the lines of a twisty road – and helping the RLX track confidently in snowy conditions – the P-AWS system counteracts understeer by helping introduce yaw – the necessary rotational effect – through the corner.

P-AWS Modes
P-AWS can provide rear-wheel toe-in, in-phase steering or out-of-phase steering, depending on the dynamic requirements as dictated by the system ECU specific key rear-wheel toe angle adjustments include:

Sport Mode

A driver-selectable Sport mode further enhances driving dynamics across a wide range of driving situations. These include:

• More linear steering response
• Enhanced turn-in feel and steering accuracy while turning and accelerating
• Improved composure during vigorous cornering
• Improved stability under deceleration
• Finely balanced steering feel in emergency avoidance situations

Lane Keeping Assist System (LKAS)

The RLX's Advance-grade features Lane Keeping Assist System (LKAS) to provide a premium driving experience by reducing steering correction movements and driving effort on the highway. LKAS uses a camera to read lane markings to assist the driver in driving in the middle of the lane.

Designed for the U.S. road structure, the system uses a camera mounted on the upper portion of the windshield to identify Botts' Dots and Cat Eye markers at speeds between 45 mph and 90 mph. When LKAS senses that the driver is drifting from the middle of a detected lane, the system generates counteracting steering torque to assist the driver in maintaining lane position, while also displaying a visual warning in the MID within the instrument panel to alert the driver about a potential lane departure. Compared to lane-keeping systems on other premium vehicles, the RLX's LKAS operates in a more linear fashion with a more natural feel.

Adaptive Cruise Control with Low-Speed Follow

The available Adaptive Cruise Control (ACC) allows the driver to set a desired speed and a distance interval behind the vehicle ahead, allowing the use of cruise control in light traffic. This system is combined with new Low-Speed Follow capability, which extends the automatic following capability to stop and go traffic situations (down to 0 mph).

Front Aluminum Subframe

The RLX has a lightweight and rigid front aluminum front subframe that is specifically designed to support the high performance of the new double wishbone, lower double-joint front suspension with Amplitude Reactive Dampers and new, belt-type Electric Power Steering (EPS) system. Using die cast front corners, instead of squeeze-castings as in the previous RL, the new RLX's front subframe is also wider across the middle, features wider middle and rear rails, and a wider rear section to accommodate the new EPS system. Rigidity is up 82 percent compared to the previous model.

With its lightweight and rigidity, the new aluminum front subframe contributes to agile and light handling, straight-line stability, higher fuel efficiency, flat cornering and pleasing ride comfort, and smooth and precise steering feel (with reduced torque steer tendencies).

The RLX subframe is matched to the Active Control Engine Mount (ACM) system that is engineered specifically for the RLX's higher-output engine and Variable Cylinder Management (VCM) system. (See Powertrain section for more information.)

Lower Double-Joint Front Suspension

An Acura first, the RLX's new double-wishbone, lower double-joint front suspension significantly improves intuitive handling agility, driver confidence and security, and ride sophistication. The system includes a lower double joint with a split lower control arm, optimized kingpin geometry, upper control arm, hydraulic compliance bushing, special dual-stage Amplitude Reactive Dampers made for Acura by ZF-Sachs, and a stabilizer bar that is heat treated for high strength.

Benefits include:

• Agility – Improved steering feel characteristics including stability, linearity, response and tracing performance
• Driver Confidence – Increased high speed linearity with reduced torque steer/pulling, shimmy and judder
• Ride Sophistication – Flat ride with reduced harshness and steering vibration

Multi-Link Rear Suspension

Like the lower double-joint front suspension, the RLX's multi-link rear suspension with Amplitude Reactive Dampers provides optimal handling agility, driver confidence and ride sophistication. The multi-link system geometry is optimized for a flat ride during cornering, confident turning capability, and a sophisticated ride in a variety of urban, highway and open road scenarios. The system includes multi-link control arms, control-arm bushings that are optimized for the best blend of NVH isolation and handling precision, Amplitude Reactive Dampers, and a rear stabilizer bar that is hardened with a special shot-peening process.

Amplitude Reactive Dampers

Amplitude Reactive Dampers provide superior ride comfort and handling in all driving conditions. The dampers have two separate damping mechanisms: one that is tuned for maximum efficiency on smoother roads with small inputs; and the other that is tuned to handle large inputs such as rough roads, potholes, and sudden steering and braking action. The result is a vehicle that remains composed and comfortable in a wide range of driving conditions.

The core technology contained within the Amplitude Reactive Dampers is their two separate damping pistons, including a main piston and a second piston. To improve overall ride comfort, when smaller inputs occur during normal driving conditions, only the main piston works to provide the ideal damping characteristics. To improve the RLX's ride and handling during more severe conditions, the second piston operates to provide additional damping force.

The Amplitude Reactive Dampers are a purely mechanical system that does not require electronic controls. Altogether, they provide a much wider range of damping performance than the previous RL.

High-Output Electric Power Steering (EPS)

The RLX's new high-output belt-type Electric Power Steering (EPS) system is a first for Acura. Using a high-power, belt-type electric steering assist, the system increases the torque available to assist the driver in steering the vehicle smoothly, with instantaneous response, direct feel, and improved low-speed agility and high-speed stability.

The variable gear ratio EPS uses a high-output electric assist motor with a belt-drive system. The system is designed and tuned to provide the two most essential characteristics in a high-performance luxury vehicle's steering. These include a smooth initial response (shorter delay) at the start of steering input, and greater linearity response (steering force camber increase) as input is increased. As a result, the RLX's high-output EPS provides agile performance in low-speed driving maneuvers such as at intersections, improved overall accuracy and road feel, and superb high-speed stability.

Rigid Steering Column

New for Acura, the RLX steering column is a highly rigid design with an aluminum bracket and resin angular bearing. The resulting stiffness gives maximum driver steering feedback along with minimizing vibration felt in the wheel.

The steering shaft is significantly larger in diameter than the shaft found in the previous RL, and together with the stiff but lightweight aluminum support bracket and angular bearing, yields maximum vibration-damping characteristics for a more luxurious driving experience.

Electrically actuated tilt and telescoping adjustment makes it easy to set the steering wheel to the ideal position for drivers of different sizes.

4-Wheel Disc Brakes with ABS and Brake Assist

All RLX models are equipped with 4-wheel disc brakes with a 4-channel anti-lock braking system (ABS) for confident stops. The front discs measure 12.3 inches in diameter, while the rear discs measure 12.2 inches in diameter.

ABS independently modulates braking power at each wheel to help the driver retain steering control during heavy braking, while Brake Assist recognizes emergency braking situations and almost instantly applies full braking force when appropriate.

The brake pads are a high-friction type for peak stopping performance even under strenuous conditions. The brake calipers are designed to reduce brake drag when not in use, reducing rolling resistance and improving fuel efficiency in the process.

The Hydraulic Brake Boost (HBB) improves brake pedal feel by utilizing a hydraulic boost system with a 10-in. high-pressure master cylinder. The system automatically and continuously analyzes and interprets the driver's brake-pedal inputs and adjusts the braking force to suit.

Electric Parking Brake + Automatic Brake Hold

The combination of Electric Parking Brake (EPB) and Automatic Brake Hold are a first for the Acura division. Together, they meaningfully reduce the effort of driving the vehicle, thereby raising overall comfort to a true flagship level.

Electric Parking Brake
Another first for Acura, the Electric Parking Brake (EPB) on the RLX makes using the parking brake easier and more comfortable. Actuating the parking brake is now as simple as pulling a button on the center console. To release the parking brake, the driver simply   presses on the accelerator pedal. In addition to being simpler, more convenient and more comfortable to use than a traditional parking brake, the new Electric Parking Brake makes hill starts easier when the RLX is parked on a grade.

The ease of use also promotes the use of the parking brake. Further, since only a few competitive vehicles have an Electric Parking Brake (EPB) system, its inclusion in the RLX further defines the new Acura as a true flagship. As with a traditional manually activated parking brake, EPB functions on the rear wheels only.

Automatic Brake Hold
Another Acura first, the RLX features Automatic Brake Hold, which retains brake pressure when the vehicle is stopped, simplifying driving in heavy traffic or hills. This frees the driver from continually pressing the brake pedal to maintain the vehicle in a stopped position, a significant improvement in driving enjoyment in difficult conditions.

Operating the system requires two simple actions from the driver:

• Activating/deactivating the system via a switch on the center console.
• Pressing on the brake pedal when the vehicle comes to a stop.

Once these steps are taken, Automatic Brake Hold will indicate engagement and then maintain brake pressure when the vehicle has come to a stop, even if the driver releases the brake pedal. The RLX then remains stopped – even on a hill – until the driver presses the accelerator pedal. At this point Automatic Brake Hold releases the brakes and the vehicle resumes normal braking function.

Vehicle Stability Assist™ (VSA®)

The RLX's high-efficiency Vehicle Stability Assist™ (VSA) works in conjunction with the ABS and the Drive-by-Wire throttle systems. This premium VSA system enhances vehicle stability when cornering. If vehicle understeer or oversteer is detected, the system selectively reduces power and/or applies braking force to individual wheels to help correct the condition and stabilize the vehicle.

Traction control monitors front-wheel slippage, such as when starting on slick surfaces or patches of ice. If it is detected, traction control activates one or more brake calipers and reduces engine torque to slow the spinning wheel so it can regain traction.

Tire Pressure Monitoring System (TPMS)

A standard Tire Pressure Monitoring System (TPMS) helps the driver maintain proper air pressure to improve driving safety and fuel efficiency, as well as reduce wear and tear on the vehicle's tires. Located in the instrument panel, a TPMS icon illuminates to alert the driver whenever any of the tires has a significantly low-pressure reading that requires the driver's attention.

Noise-Reducing Wheels

The RLX and RLX with Navigation models feature 7-spoke, 18x8J noise-reducing alloy wheels, while the Technology, Krell and Advance grades feature larger 19x8J noise-reducing alloy wheels with seven sets of paired spokes. Both wheels have a painted Glitter Silver Metallic finish.

All RLX wheels have a special noise-reducing design that lowers noise by as much as 7 dB across the audible frequency range. The key elements of the noise-reducing four resin moldings fitted on the inside of the wheel rim. The result is reduced noise resonance in the air column inside the wheel.

All-Season Tires

Michelin all-season tires are standard equipment on all RLX models. The RLX and RLX with Navigation models use 245/45R18 M+S tires – the same size as on the previous Acura RL – while the Technology, Krell and Advance models use lower-profile 245/40R19 M+S tires. The RLX features an easy-to-use tire repair kit in lieu of a spare tire. This reduces weight and increases trunk volume, and simplifies temporary repairs in the event of a flat tire.

Capless Fueling System

A first for Acura, the RLX's capless fueling eliminates the fuel cap, meaning that fueling the vehicle now simply requires opening the fuel-tank lid, refueling, and then closing the lid. This reduces the possibility of damaging the vehicle's paint with the fuel cap or tether, or forgetting the fuel cap at the gas station. The system also allows the use of a smaller fuel-cap door, which cleans up the lines of the vehicle.

The system consists of two integrated components, including an outer shutter mechanism that prevents the intrusion of dirt and dust, and a self-sealing fueling flap that is closed by a torsion spring. Both operate automatically.

At a gas station, the driver simply opens the fuel lid (which automatically locks with the doors) and then inserts the fuel nozzle. Inserting the nozzle automatically opens the outer shutter and fueling flap. When fueling is complete, removing the fuel nozzle automatically closes both the fueling flap and outer shutter.

18.5-Gallon Fuel Capacity

The RLX's resin fuel tank capacity of 18.5 gallons gives the RLX an ample cruising range. Both the fuel tank and fuel pipe are made of high-impact resin for lightweight and durability. The fuel tank is located in a protected area in front of the rear suspension.

2014 Acura RLX - Interior

The 2014 RLX interior is an all-new design that serves as a "gracious host" for the driver and passengers, combining highly spacious five–passenger comfort with a higher level of luxury convenience and technology in an Acura flagship sedan. In the front seat area, a design concept called "dual personal structure" divides the space into areas centered on the driver and front passenger, complemented by a wide center stack and console that is easily accessible to each person. High-end premium elements, such as a carefully stitched leather instrument panel cover, soft-touch materials, premium finishes, and rich wood-grain accents, combine with an intuitive new control layout to create a distinctive environment in tune with this luxury performance sedan's sporting character.

Open the door with the standard Smart Entry system and you'll find more shoulder room, front and rear. Rear seat leg room has been increased a substantial 2.5-inches, moving the RLX to the head of its class in tandem seating distance. Heated 12-way adjustable (8-way power plus 4-way power lumbar support) front seats are standard, and offer all-day comfort along with abundant lateral support for aggressive cornering. Ventilated front seats and heated rear seats are standard in the Advance grade. Rich, luxurious perforated and stain-resistant Milano leather seating is standard in the Technology, Krell Audio, and Advance grades; the base grade has leatherette trimmed seating.

Standard tri-zone climate control ensures passenger comfort throughout the cabin. All grades have a large center console that offers 9.9 liters of storage space, and features a padded armrest lid that slides fore and aft for greater comfort. The dual-hinged lid can be opened to the left or right, making access simple for either the driver or front-seat passenger. The glove box has a new electric release, and along with the audio, navigation and phone systems, can be easily locked via the touch screen – for situations where additional security is warranted, such as when RLX is given to a valet for parking.

With the expanded range of standard and available technology features, substantial engineering effort was put into making each feature intuitive and easy to use. The focal point of the new instrument panel is a large 8-inch color audio/information screen that provides a range of useful information and access to an array of customizable features. When equipped with a navigation system, a high-resolution screen positioned in this same location combines audio, information and navigation functions.

A 7-inch On-Demand Multi-Use Display™ positioned within easy reach of the driver and front passenger controls the audio system and many other features. The touchscreen eliminates many physical buttons, and is the key contributor to the clean, uncluttered look of the new RLX interior. Dynamic menus clearly display controls for each functional mode, reduce screen clutter, and help make operation simple. Audible and touch feedback improves usability and control, and helps keep the driver's eyes on the road. Customizable shortcuts allow the RLX driver to set easy-to-access pre-sets for Places, Phone, Climate, Audio, and Valet functional categories.

Befitting its flagship status in the Acura line, the RLX does not scrimp on thoughtful premium details. A power tilt/telescoping steering wheel with enhanced fingertip controls and a multi-view rearview camera are standard. Also standard are a two-driver memory system, auto-dimming rearview mirror, HomeLink®, Forward Collision Warning (FCW) and Lane Departure Warning (LDW). To deliver excellent sound isolation, the RLX makes use of comprehensive sound deadening materials, an acoustic glass windshield, and an Active Sound Control system that helps cancel out interior noise.  Acura Bluetooth® HandsFreeLink® wireless telephone connectivity is also standard, and allows the RLX driver to dial a Bluetooth®-enabled mobile phone by voice command.

Acura is known for its leadership in the adoption of advanced information and media technologies, and the 2014 RLX further expands on this concept. The next generation of AcuraLink®, available in navigation-equipped RLX models, delivers a broad spectrum of capabilities using both an embedded two-way cellular communication and cloud-based connectivity via the owner's compatible smartphone and data plan. AcuraLink features Pandora® interface, Aha™ by Harman cloud-based interface, and SMS text and e-mail messaging3 functionality with compatible cell phones.

The Pandora® interface allows custom internet radio stations to be played through the RLX audio system via a connected compatible smartphone. Aha also uses a paired smartphone to provide hundreds of channels of in-vehicle content, including custom internet radio, podcasts, audio books, Facebook and Twitter newsfeeds. AcuraLink services are offered in three tiers: Standard, Connect and Premium

Exceptional audio performance has long been an Acura hallmark, and in the RLX the bar has been raised further still. Three audio systems are offered, starting with an impressive Acura/ELS® 10-speaker premium sound system in the RLX. The RLX with Technology package is equipped with an Acura/ELS Studio® Premium Audio System with 14 advanced speakers. In Krell Audio and Advance grades, a 14-speaker Krell premium audio system — with speakers and amplifiers engineered over the last four years — sets a new benchmark in automotive audio performance.

All RLX grades offer a wide spectrum of audio and information features. All audio systems feature AM/FM, HD radio and XM radio®. The standard USB port allows the connection of a flash drive, iPhone or iPod. Compatible Bluetooth® devices can also connect to the RLX wirelessly. When equipped with a navigation system, CDs can be copied onto the on-board hard drive and selected using Song-by-Voice.

The available Acura Navigation System with Voice Recognition™ is a hard-drive based system that is standard in the RLX with Navigation, Technology, Krell Audio and Advance grades. It features continuously updated traffic maps, including highways and, for the first time, surface street traffic information within the United States and Canada, and also offers traffic rerouting to help navigate around slow-downs. The system includes Zagat® restaurant information.

The navigation system's voice recognition feature allows you to perform the most frequently used functions of the audio, climate control, and navigation systems without taking your hands off the wheel. The advanced voice recognition technology responds to over 1,500 commands, in addition to spoken street names.

A new spectrum of driver-assistive technologies is also offered on the RLX. Forward Collision Warning (FCW) and Lane Departure Warning (LDW) are standard; the Technology grade adds the Blind Spot Information (BSI) system; the Advance grade has standard Adaptive Cruise Control (ACC) with Low-Speed Follow, Lane Keeping Assist System, and front and rear parking sensors.

Design and Materials

The new RLX interior is a fresh take on premium luxury, with clean and elegant lines, high-end detailing, and intuitive functionality. A design concept called "dual personal structure" guided development, and divides the space into areas centered on the driver and front passenger, complemented by a wide center stack and console that is easily accessible to each person.

With more on-board electronic features than ever before, the RLX designers rethought the user interface of the central stack, and developed a simple two-screen system. The 8-inch color audio/information screen is placed high in the instrument panel, where it's close to the driver's sight line. The lower, 7-inch touch screen eliminates the need for dozens of hard keys, and has contextual menus that make operation simple. The quality of interior materials, fit and finish have received close attention to reflect the discerning nature of the RLX owner, with stitched leather instrument panel detailing, available Milano leather seating, and soft-touch materials throughout.

Driver-Oriented Cockpit

Intuitive functionality has always been a priority in Acura design and is now a core element of Acura's focus on creating the synergy between man and machine – enabling the driver to focus on operating the vehicle rather than various controls. All important systems and controls are within easy reach of the driver. Controls for the systems used most frequently—audio, cruise control, Bluetooth® HandsFreeLink® , available satellite-linked Acura Navigation System with Voice Recognition™ and Multi-Information Display—are conveniently positioned on the steering wheel. The main instrumentation is an easy-to-read analog design, supplemented with digital and graphic displays. Even though the RLX gives its driver access to many electronic features, the interface is simple and welcoming. Sight lines are clear with important items placed within easy view.

Typical of Acura interior design, the soft-touch switchgear of the RLX is engineered to deliver a quality feel and positive action. Helpful features, such as power side mirrors that can be set to automatically tilt-down when Reverse gear is engaged, make parking easier. A standard multi-view rearview camera provides a choice of three different views, displayed on the bright, colorful 8-inch audio/information screen.

Leather-Wrapped Steering Wheel

The leather-wrapped steering wheel with euro-style stitching incorporates the most commonly used controls, allowing the driver to keep their hands on the wheel. Phone and audio controls are on the left side; cruise control and multi-info display controls are on the right side, along with the switches for Lane Keeping Assist System (LKAS) and Adaptive Cruise Control with Low-Speed Follow on the Advance grade.

Tucked out of view but within fingertip reach are a pair of paddle shifters that allow for manual operation of the Sequential SportShift 6-speed automatic transmission.

Instrumentation

The RLX has sophisticated analog instrumentation with large tachometer and speedometer flanking a Multi-Information Display (MID) which provides a range of information and trip computer functions. The tachometer and speedometer are flanked by an analog coolant temperature and fuel level gauge.

Multi-Information Display

A highly functional instrument panel gives the RLX driver instant access to critical information. It also provides important vehicle information via a Multi-Information Display (MID) positioned between the tachometer and speedometer. Controls positioned on the right side of the steering wheel allow the driver to cycle the MID display through multiple screens of information from sources including LKAS and ACC and more. The Maintenance Minder™ system alerts the RLX driver of upcoming maintenance needs via the MID and should a fault occur with the vehicle, specific warning information will appear.

MID information categories include:

• Digital odometer and dual digital trip meters
• Average fuel economy
• Estimated remaining fuel range
• Elapsed time
• Average speed
• Maintenance Minder™
• Tire pressure monitoring system (TPMS)
• Vehicle Settings customization
• Engine oil life
• Outside temperature
• Instant fuel economy
• Shift lever position
• Adaptive Cruise Control (ACC) with Low-Speed Follow
• Lane Keeping Assist System (LKAS)
• Turn-by-turn navigation (with Navigation package and up)

Audio/Information Screen

All RLX models feature a bright, full-color 8-inch audio/information screen positioned high in the center stack of the instrument panel. Its high placement puts it close to the driver's line of sight where it's easy to see. Besides audio system information, the screen also offers backup camera views and access to a range of customizable features.

On-Demand Multi-Use Display™

The impressive range of technology offered in the RLX presented designers with a challenge of balancing capability with simplicity. The solution came in the form of a 7-inch On Demand Multi-Use Display™ (ODMD) touch screen positioned within easy reach of the driver and front passenger. The touchscreen controls a wide range of features, and with its contextual menus, it displays relevant items while minimizing clutter. To make it easy to use, the screen offers audible and vibratory touch feedback—both can be adjusted or shut off based on the owner's preference. Customizable shortcuts allow the RLX driver to set easy-to-access presets for Places, Phone, Climate, Audio and Valet functional categories.

The touchscreen display also provides access to the RLX's Valet Mode. Using the touch screen, the owner can assign a Personal Identification Number (PIN) that locks out the use of the trunk release and glove box, navigation system, audio system and phone.

Multi-Angle Rearview Camera

A multi-view rearview camera is standard on all RLX grades. It offers three viewing angles (wide view, normal view and top view). Drivers may select the preferred view according to driving conditions. The rearview image is displayed on the 8-inch color audio/information display, or on the navigation system display (in the same location) on models equipped with navigation. On-screen guidelines help the driver better judge distances, and predictive guidelines help make maneuvering in reverse easier. (See the Body Section for more information.)

One-Touch Turn Signals

The RLX's one-touch turn signals provide increased convenience for the driver when making routine lane changes. In addition to normal operation, a quick movement of the turn signal lever (between 0.4 sec. and 1.0 sec.) will cause the turn signals to flash three times.

Seating

Considering the luxury mission and performance capabilities of the RLX, its seating required extensive engineering development. Detailed analysis of seats from competitive makes helped set engineering targets that balanced firm support, a feeling of secure stability when maneuvering, and the supple comfort required for all-day driving.

An all-new internal structure lays the foundation for comfort. Specially compounded padding in four different densities is used strategically to blend support and comfort, with special firm inset pads positioned internally in the side bolsters for stable lateral support. Special attention was given to the seat covering material (synthetic leather in the base RLX, Milano leather in Technology package and higher grades) to make for a soft touch, with the right amount of surface friction to help keep passengers securely in position while cornering.

The RLX driver and passenger front seats feature 12-ways of power adjustability (8-way power seat plus 4-way power lumbar support). The pneumatic lumbar support can be adjusted both longitudinally and vertically. All driver's seat power adjustments are included in the Smart Entry system that (among many other features). The system stores a pair of user profiles regarding seat settings—one for each of the two key fobs that come standard with the RLX.

Heated front seats are standard in the RLX. Electronic control allows for three temperature settings, along with faster warm-up and smoother, more precise temperature control. Ventilated front seats and heated rear seats are standard in the Advance grade.

The RLX offers rear seat occupants exceptional comfort and room. Specially sculpted front seat seatbacks generate extra leg room for rear seat passengers. In the rear seat area, the outer seating positions are carefully engineered (complete with side bolsters) to simultaneously combine solid lateral support with luxurious comfort on long trips.

Interior Lighting

The RLX theme of efficient driver control and easy-to-read components carries on after dark. The analog instruments are backlit with LED lighting and feature high-contrast markings. The gauge package progressively illuminates to give the driver a welcoming feel upon entry. When the door is first opened, the instrument lighting comes to life and then brightens progressively to 100-percent illumination when the ignition is switched on. The illuminated instrument panels then come alive, indicating that the car is ready to go. At the end of the drive, the instrument lighting dims progressively.

All the interior switches and vent controls are illuminated to make them easy to locate at night, including the switches on all four doors and the steering wheel. In addition to front and rear overhead interior lights and map lights, the RLX also has a complement of low-level interior cabin lighting. Ambient lighting in the ceiling illuminates the front center console and the rear flip-down armrest. The front foot wells also have ambient lighting that brightens substantially when the doors are opened.

Front and rear interior door handle areas are illuminated to make them easy to find at night, and the front door storage compartments, glove compartment, and center armrest compartment are all internally illuminated. All four doors have courtesy lights that illuminate when the doors are open. The RLX interior lights feature "theater dimming," which can be set by the driver to one of several dimming rates via the Multi-Information Display. The trunk has interior lighting, plus the trunk lid has lighting that illuminates the bumper and sill area when the lid is opened.

Interior Convenience

The RLX interior offers a range of storage and convenience features for the driver and passengers. The dual-hinged front center armrest incorporates a unique lid design that can flip open to the right or left, for the convenience of the driver or passenger. The padded armrest also slides fore and aft. Inside the roomy storage compartment, there's space for an iPad or a small laptop computer.

A USB port inside the console allows for easy connectivity of items such as an iPod®, iPhone® or a removable flash drive storage device. The USB port is located alongside a traditional AUX jack that allows connectivity of an MP3 music player. Just ahead of the console, a pair of illuminated cupholders are conveniently positioned.

Inside the glove compartment is a separate document box to accommodate the Owner's Manual as well as important registration and insurance papers. The separate document box arrangement not only keeps paperwork neatly contained, but it also frees up storage space in the main glove box compartment. In the rear seating area, a wide fold-down center armrest has a padded top. A pullout dual beverage holder is built into the rear armrest.

Cargo Carrying Versatility

The RLX has a generously sized, 15.3 cubic-foot trunk (15.1 on Krell Audio and Advance packages) that is fully finished, with all wiring concealed along with the rear parcel shelf speakers being fully protected. A pair of underfloor compartments provide added space for small items. The acoustic properties of the trunk and the rear deck speakers were specially engineered to create the best possible sound performance from the three available audio systems. To allow room for longer items, a locking trunk pass-through is provided. A cargo net with a network of anchor points help keeps trunk cargo securely in position.

For a cleaner appearance and to avoid damage to luggage, the trunk lid is supported by fully concealed hinge mechanisms. The trunk can be opened via a remote release mounted on the driver's door panel, by pulling the exterior release lever on the trunk lid (when carrying the Smart Entry keyless access fob), or with a manual release accessible through the locking trunk pass-through. There is also an emergency trunk opener, located near the trunk latch, that can be found in total darkness thanks to a glow-in-the-dark yellow color treatment.

GPS-Linked, Tri-Zone Automatic Climate Control

The RLX has an available unique GPS-linked temperature control, tri-zone automatic climate control system that lets the driver, front passenger and rear passengers set temperatures to their individual liking. Designed for exceptionally quiet operation the system also includes a selectable automatic recirculation mode that is controlled by an electronic control unit (ECU) and an air quality sensor.

To operate the HVAC system, easy-to-read buttons and controls are positioned within easy reach. The HVAC system can also be controlled by voice command, and additional custom settings can be accessed through the 7-inch On-Demand Multi-Use Display™ interface. The climate control system's control logic is designed to provide smooth operation with subtle changes in airflow.

With its position-sensing ability, the available GPS navigation system contributes to overall passenger comfort with a 3D solar sensing feature. Based on continuously updated vehicle position information, the navigation system determines the position of the sun relative to the driver and passenger. Combining this information with input from a solar sensor located on top of the instrument panel, the climate control system automatically adjusts the temperature and airflow from side to side as needed to compensate for asymmetrical solar heating.

Rear Sunshades

For increased rear seat privacy, reduced solar loading and greater passenger comfort on sunny days, the Krell Audio and Advance grade RLX models have a power operated rear-window sunshade along with manually operated expanded sunshades for each rear door side window.

Active Noise Control (ANC) and Active Sound Control (ASC)

Key contributors to the RLX's quiet, refined interior are Active Noise Control (ANC) and Active Sound Control (ASC). The two systems are comprised of dual overhead microphones, an ANC/ASC electronic processor, and the audio system's speakers. ASC/ANC operates whenever the RLX engine is running, even if the audio system is turned off.

ANC is designed to reduce low frequency sound in the cabin caused mainly by the roughness of the road surface. The overhead microphones pick up sound waves and send them to the ANC/ASC processor, which creates and sends a precisely timed "reverse phase" audio signal to a special amplifier. In turn, the amplifier drives the door speakers to cancel the original noise signal.

ASC is a related technology designed to improve the engine sound quality by making the sound pressure level more linear as the engine revs increase. Typically, engine noise doesn't increase in a linear way with rising revs; instead there can be many resonances that create peaks and valleys in the sound pressure level and an uneven sound. ASC helps smooth out the engine sound by creating a same-phase or reverse-phase sound signal as needed and sending it to the speakers. Though the system offers benefits from idle to redline, it makes the largest difference in the range between 1000 and 2000 rpm, where it lowers the sound pressure level with a reverse-phase audio signal.

AcuraLink® Connectivity System

The RLX launches the next generation of AcuraLink®, Acura's cloud-based connected car system that first launched in 2005. This new generation uses embedded cellular technology built into the RLX, along with the owner's compatible smartphone and data package, to bring a broad range of convenience, entertainment and available security features to the RLX.

AcuraLink is the new center point for owners for hands-free access to cloud-based services, audio and information, and is designed to keep RLX drivers informed and connected while on the go. AcuraLink is available on RLX packages equipped with navigation: RLX with Navigation, Technology, Krell and Advance packages.

The connectivity required for AcuraLink's various features is distributed between the RLX's embedded system (for some of the fee-based features) and the owner's compatible smartphone and data package (for free features).

AcuraLink works with the owner's compatible smartphone and data package to connect the RLX with music and information resources, internet apps, and more.

Pandora® Interface
The RLX incorporates a wide range of media features to accommodate the ever-changing preferences of customers. All RLX models are designed to provide a convenient interface for Pandora®. Pandora® is a free music service that allows users to open an account online and create up to 100 personalized internet "radio stations" that are based on favorite songs or artists. Users can choose among their stations and listen via computer, and can also download a free smartphone Pandora® app, which allows users listen to the same list of personalized stations via their compatible phone. Although Pandora® is free, phone data charges apply.

An iPhone or compatible Android phones can be connected wirelessly, using Bluetooth® HandsFreeLink® (iPhone is also supported via the Pandora® Audio USB interface). To use Pandora®, the Pandora app is launched on a compatible connected smartphone and the vehicle's audio source is set to Pandora®. The audio/information screen (or navigation display in vehicles with navigation) and On-Demand Multi-Use Display™ shows Pandora® information and album art, and the audio controls allow listeners to choose from among existing stations, pause, resume, skip forward, and mark a track with "Like" or "Dislike" ratings. Some functionality of the Pandora® app is locked out when using the RLX's Pandora® interface.

SMS Text Message Function

All RLX models have a standard SMS Text Message function that can read incoming texts aloud over the audio system, and allow the driver to reply with any of six factory preset messages (see below). The system works with SMS-capable cell phones that have an active data plan and the Message Access Profile (MAP), such as the Blackberry, Droid X and others. When running iOS6, an iPhone can receive text messages, but cannot send replies using the RLX interface.

Once a compatible phone is paired with the RLX's Bluetooth® HandsFreeLink® system, the text messaging function is enabled. When the phone receives a text message, an alert appears on the audio/information screen (or navigation screen in vehicles equipped with navigation). Using the audio system controls, the driver can choose to have the message read aloud, can select among the preset reply choices, or can call the sender – all without handling their phone. To help minimize driver distraction, the text of the incoming message is not displayed on-screen while the vehicle is moving.

Available factory preset text replies:

• Talk to you later, I'm driving
• I'm on my way
• I'm running late
• OK
• Yes
• No

Bluetooth® HandsFreeLink® Wireless Telephone Interface 

Like all Acura vehicles, the RLX has a standard Bluetooth® HandsFreeLink® hands free telephone interface that is designed to work with most Bluetooth®-enabled mobile phones. Bluetooth® is a radio frequency-based technology that allows portable devices (such as mobile cellular telephones, PDAs, and laptop computers) to communicate wirelessly. The RLX's HandsFreeLink® system is compatible with Bluetooth®-enabled cellular phones that have the Hands Free Profile (HFP). After the driver completes a one-time pairing process, the RLX can communicate wirelessly and securely with the driver's cell phone when it is within approximately 10 feet of the car. The phone needs to be on, but can be stored in a pocket, briefcase, purse, or anywhere inside the RLX cabin— thus there is no need to worry about where to place the cellular telephone.

Bluetooth® HandsFreeLink® allows the driver to send or answer telephone calls without removing their hands from the steering wheel. When a call comes in, the number of the incoming caller is displayed on the Multi-Information Display (MID) located in the instrument cluster. In addition, the phone ring tone is played over the audio system. If the driver chooses to answer the phone call, a press of the steering wheel-mounted "Pick up" button mutes the audio system and the incoming caller is heard over the RLX's audio system speakers. Working with an overhead array microphone, the HandsFreeLink® system helps cancel "echo effect" and reduces background noise to improve the transmission quality of the driver's speech.

To send a call hands-free, the RLX driver can dial the number by voice, again using fingertip controls mounted on the steering wheel to activate the system. The driver also can store frequently called numbers in the system's memory using unique voice tags. Up to six different compatible mobile phones can be registered with the RLX's Bluetooth® HandsFreeLink® system.

Audio/Connectivity Feature Summary

Acura/ELS® 10-Speaker Audio System

The RLX comes standard with a 10-speaker Acura/ELS® system that is engineered to offer impressive sound quality from a wide range of media formats. Engineered specifically for the RLX by Panasonic and legendary recording engineer Elliot Scheiner, the system has a single-disc CD player, AM/FM/HD/XM/HDD and delivers detailed, well-balanced sound to all seating positions. The system gets its name from multi-Grammy® Award winning producer/engineer Elliot Scheiner's recording industry-recognized moniker "ELS®." Scheiner's goal in the development of this audio system was to reproduce music the way it is heard in the recording studio.

Along with a physical knob for power and volume, the full range of audio system controls can be accessed using the 7-inch On-Demand Multi-Use Display™ positioned within easy reach of the driver and front-seat passenger. Controls for key audio system functions are positioned within fingertip reach on the RLX steering wheel. Select audio system functions can also be accomplished via voice command in RLX models equipped with navigation.

For precise audio imaging, ten speakers are strategically located throughout the RLX cabin. Each front door has a 6.5-inch full-range speaker. Separate 1.5-inch tweeters are positioned near the A-pillars, with a 3.1-inch speaker centered on the top of the instrument panel. The rear deck has a 6.5-inch full-range speaker and a tweeter on each side, with an 8-inch subwoofer centrally located beneath the rear glass.

In addition to traditional source inputs, the RLX is fitted with a USB port that allows for easy connectivity to items such as an iPod® or iPhone® along with a removable flash drive storage device containing WMA, MP3 or AAC format music. The USB port is located alongside a traditional AUX jack (that allows connectivity of an external MP3 music player) located in the center console's storage compartment.

XM® Radio
XM® Radio is a standard feature within the RLX audio system and it provides more than 200 channels of digital programming with near CD-quality sound. The XM® signal is beamed to two broadcast satellites positioned in geostationary orbit above Earth. The beams from these two broadcast satellites combine to span the entire continental United States and some of Canada.

XM® Radio programming includes channels devoted to music, sports, talk, traffic, weather, children's programming and entertainment. Of the more than 200 XM® channels, 71 are commercial-free. When the RLX's audio system plays XM® Radio, the Audio/Information screen (or navigation display in vehicles with navigation) displays the current category, station song title, or artist's name, while the current category and station are also displayed on the On-Demand Multi-Use Display™. A complimentary three-month subscription to the XM® Radio service is included with purchase of a new RLX, and customers are able to continue the service or cancel any time afterwards.

HD Radio
All RLX models feature standard HD Radio. HD Radio technology converts the traditional analog radio broadcast to digital and provides advanced audio and data features that enhance the listening experience. Sound quality is radically improved, and unlike satellite radio, HD Radio is free.

Instead of sending out one analog signal, HD stations send out a bundled signal – both analog and digital. Because it is digital, textual data such as traffic, stock info and song titles can be sent out, as well. Unlike conventional radio, HD Radio stations broadcast extra channels, which are called HD2/HD3. These added channels offer RLX owners a universe of additional choices.

Acura/ELS Studio® 14-Speaker Premium Audio

The RLX with Technology grade features the Acura/ELS Studio® Premium Audio System. With 14 speakers, this Elliot Scheiner engineered system is designed to recreate the emotional experience you feel when you enjoy a live performance. The system's hardware matches the quality of recording studio equipment, and features high power amplification and advanced speaker technology.

The system's 14 speakers are precisely located throughout the RLX cabin. Six titanium-domed tweeters are arrayed in the interiors; two near the A-pillars, two in the rear doors, and two more on the rear deck. A 3.1-inch super dynamic range speaker is centered in the top of the instrument panel, and six big 6.7-inch super-dynamic range speakers are placed in the door and on the rear deck. Finally, an 8-inch SLDD (Super Low Distortion Driver) subwoofer is position in the center of the rear deck.
 
Hard Disk Drive (HDD) Audio
Hard Disk Drive (HDD) audio system featuring the 15GB HDD-based memory are programmed from the factory to copy music tracks from pre-recorded CDs, enabling customers to store many CDs worth of music on-board for easy access. The system will not copy music from burned CDs or from USB flash drives. Based on music files measuring an average size of 4.2MB per song at a 128kbps bit rate, approximately 3,500 songs can be loaded into the 15GB system (approximately 175 CDs).
The HDD-based system records music at 6-times that of the original music track time. Two recording quality settings (192 kbps or 128 kbps) are available. The automatic-recording default setting can be changed to manual if desired.
The audio system can display information about the music tracks, such as artist names and song titles using the Gracenote® database in the system software. This database can be periodically updated to reflect newly released music. Gracenote updates can be downloaded by RLX owners at automobiles.acura.com in the Ownerlink section (up to four updates per year maximum). The updates can then be loaded onto a CD-R or onto a USB thumb drive, which in turn can be used to update the RLX audio system. Even without a Gracenote update, newly released audio tracks will play on the sound system, without accompanying text information on genre, artist, album name and track name.
Song By Voice®
Navigation-equipped RLX models feature the Song by Voice® feature. From most navigation screens, the driver can simply press the TALK button on the steering wheel. With so much audio content potentially available on the HDD or from an iPod, RLX engineers set out to make it easy to find content. So drivers can simply give a voice command, such as "Play song 'Danny Boy,'" and the system will automatically begin playback. Song by Voice also lets the driver choose music by artist, album, track name, genre, playlist and even composer.

Krell 14-Speaker Ultra-Premium Audio System

The RLX with Krell Audio and Advance grades feature a Krell audio system that is designed to set a new standard in automotive audio performance. Krell is one of the most highly respected names in high-end audio, with a three-decade history of developing ultra-premium home audio systems. Krell's home components include $5,000 pre-amplifiers, $12,500 amplifiers and $65,000 speaker systems that are engineered to unmatched standards. Though the new RLX system marks Krell's first production automotive application, it shares the performance goals of all Krell systems: Musical detail, three-dimensional sound presentation, and extreme volume capability. Four years of development went into the RLX 14-speaker system.
 
The 14 Krell speakers are positioned in the RLX cabin in the same locations as those in the Technology package. Six magnesium-domed tweeters are arrayed in the interior; two near the A-pillars, two more in the rear doors, and another pair on the rear deck. A 3.1-inch speaker is centered in the top of the instrument panel, and six large 6.7-inch Zylon speakers are placed in the doors and on the rear deck. Finally, an 8-inch subwoofer is positioned in the center of the rear deck.
 
Krell uses highly advanced speaker technology to achieve a new level of audio performance. The tweeters, for example, use magnesium diaphragms. Reproducing high frequencies requires that the tweeter diaphragm be able to move extremely fast, so ideally the diaphragm should be constructed of materials with very low mass. Aluminum is lightweight, fairly rigid, and inexpensive, but an aluminum diaphragm structure has a strong inherent resonance of around 20 kHz. This resonance is often perceived as a harsh or gritty sound. Magnesium is more expensive than aluminum, but it has the benefit of being less mass. Adding a structural ridge to the diaphragm greatly increases rigidity without additional mass. This pushes the diaphragm's resonant frequency up into the inaudible 40 kHz range. The result is extraordinary detail and extended high frequencies without any trace of harshness.

Special technology is also applied to the Krell system's six 6.7-inch speakers. The speakers use diaphragms constructed of a material called Zylon, the world's strongest super-fiber. This very rigid material is ideal for speaker manufacturing. Zylon responds very quickly to musical input and, more importantly, stops moving just as quickly when the musical signal stops. Compared to the polypropylene diaphragm material that is used in the vast majority of car audio speakers, Zylon has far less unwanted vibration, resulting in a much cleaner and more detailed sound.

Because of the ability of the magnesium tweeters and Zylon speakers to reveal fine details in the music, the highest quality crossover components were required. Heavy gauge, pure copper inductors and top-of-the-line polypropylene capacitors from Bennic maintain perfect signal integrity.

The discrete amplifier channels are designed exactly like the channels in a high-end Krell home amplifier. The main channels feature the same robust, high quality bipolar power transistors used in flagship Krell home amplifiers. The result is an amplifier that has one-third less distortion than amplifiers found in competing flagship luxury sedans. Using a class D channel for the subwoofer increases that amplifier's efficiency and reduces its size. The DirectFET class D amp is designed for low EMI (electro-magnetic interference) to keep the main output channels as noise-free as possible.

For the best audio performance, the Krell system uses metal speaker grilles. Because metal is inherently stronger than the plastic used for most grilles, the grilles can have a more open area without compromising strength. Metal grilles also vibrate less than typical plastic grilles.
 
Special care went into mounting the speakers with mounting plates that are thick and heavily reinforced. In combination with the specially engineered door panels, the mounting plates provide an extraordinarily rigid, stable mounting surface for each speaker element. Sound energy that would otherwise be wasted in the drive-unit or door vibration is accurately transmitted to the listener, resulting in tighter bass response and improved musical detail.

System Operation
The RLX's Acura Satellite-Linked Navigation System uses GPS technology and a 60 GB hard disk drive based (HDD) system to provide drivers with turn-by-turn guidance to their chosen destination. The system adds surface street traffic data for the RLX and provides coverage in many areas within the U.S., allowing the driver to choose faster, less congested routes. The system offers a new level of convenience, with the new generation of AcuraLink. Owners can send a destination to the vehicle in advance of trip using AcuraLink (with the optional Connect Package), or while on the road via the AcuraLink Concierge operator (with the optional Premium Package) or the interactive voice response system (with the Connect Package). Faster, more capable and easier to use than any previous-generation Acura system, the RLX navigation system sets a new standard.

The RLX navigation system features an 8-inch high-resolution WVGA (800x480 pixel) backlit color display that takes the place of the audio/information display in non-navigation models. The system can be controlled by voice, or with a convenient interface dial. The new technology allows the voice-activation system to respond to casual command phrases that require less user familiarization, in addition to the previous capability of being able to understand spoken city and street names. For example, a voice request for "Radio 98.3 FM" can now be spoken in approximately a dozen different ways ranging from "change the radio station to 98.3" to just saying "98.3 FM." This logic applies to audio functionality of the audio/information screen. The navigation system can also be controlled by voice with conventional navigation commands like, "Find nearest Chinese restaurant" or "Find nearest ATM."

The audio system is automatically muted when the "Talk" button is pressed. The voice-recognition technology allows the driver to simply speak city and street names aloud, and the system responds by displaying the matches available in the database. Points of interest on the map (such as restaurants or grocery stores) can be displayed with brand logo icons, or the system can provide turn-by-turn navigation – all by voice command. The massive point-of-interest (POI) database includes telephone numbers that can be dialed by using the Bluetooth® HandsFreeLink® system when the driver's cellular telephone is connected to the system.

The Acura Navigation System uses Global Positioning Satellites (GPS) in combination with detailed information from the vehicle's mapping system to pinpoint the vehicle's location and to provide a host of useful mapping and route guidance features. The antenna can utilize up to 12 satellites from a network of 24 global positioning satellites. If the antenna is obstructed by a tunnel, a parking garage or a tall building, an internal gyroscopic system and a speed sensor track the location of the vehicle so that the map information remains current and reliable. The vehicle clock is independently controlled by GPS data, so when time zones are crossed while driving, the clock will automatically set itself to the current time.

The RLX's navigation screen can display regularly updated traffic information including traffic flow, incidents and construction on freeways, and for the first time, on surface streets. The information is from Probe Traffic, a system that tracks the movements of participating Acura (and other) vehicles to generate up-to-date flow information. Participants opt into the Probe Traffic system to receive flow information, which is anonymous and scrubbed of any personal information. The flow information is transmitted via the RLX's embedded cellular data link and is graphically displayed on the navigation system.

The system can automatically recalculate a "detour" route and display a pop-up box signifying the route change, when traffic congestion or road incidents are detected along the selected drive route. Alternately, the driver can recalculate a route in manual mode simply by selecting "TRAFFIC INCIDENTS" from the Map Info menu followed by selecting the "AVOID" command relevant to an incident.

A digital version of the Zagat Survey® restaurant guide provides detailed information and reviews on select restaurants in the database. The reviews can be read on-screen or spoken over the audio system by a synthesized voice.

The navigation system can also suggest scenic routes based on the National Scenic Byways and All-American Roads guide. The U.S. Secretary of Transportation recognizes certain roads as All-American Roads or National Scenic Byways based on one or more archeological, cultural, historic, natural, recreational and scenic qualities. Scenic-route information for 126 routes can be accessed from inside the "Information" menu and is displayed on the map as a green-and-red segmented line.

Forward Collision Warning (FCW)

The RLX features a new Forward Collision Warning (FCW) system as standard equipment. When the camera-based system detects a vehicle ahead and determines that collision is possible, it provides the driver with visual and audible alerts to encourage avoidance actions. (The system does not include an automatic braking function).
(See Safety section for more information.)

Lane Departure Warning (LDW)

Lane Departure Warning (LDW) is new for the RLX, and provides the driver with visual and audible alerts if the vehicle begins to move out of a detected lane without the turn signal activated. A button on the lower left portion of the instrument panel allows the system to be switched on and off.
(See Safety section for more information.)

Smart Entry Keyless Access System

The RLX features Acura's Smart Entry with Push Button Start. The Smart Entry system lets the RLX owner gain access to the vehicle without having to operate the key fob or conventional key. The Smart Entry remote has a unique digital identity and the RLX can be unlocked when the driver grabs one of the door handles (front doors only on the RLX and RLX with Navigation) while the remote is in his/her possession. When carrying the fob (or if all doors are unlocked), the trunk can be opened by pressing a button located on the RLX's rear fascia.

Once the driver has opened the door and is seated, the Smart Entry system allows the RLX to be started by pushing the Engine Start/Stop button positioned on the instrument panel. When leaving the car, a press of the soft-touch button on the exterior door handle locks all the doors. Alternatively, pressing the Lock button on the Smart Entry remote will also simultaneously lock all doors.  

Smart Entry also features a unique "quick vent" feature.  When the operator depressed the "unlock" button on the keyless remote for two seconds after unlocking the doors, the system lowers all four windows and opens the power moonroof to quickly vent built-up interior heat. In addition, by inserting the built-in key into the driver's door lock and holding the key in the "lock" position, all open windows can be simultaneously raised.

Preferences
The Acura RLX comes with two keyless remotes that can be set with a unique preference to accommodate the preferences of two different drivers. The available preferences include driver seat, steering wheel and mirror positions, along with select HVAC functions. Other preferences include turning entry lights on or off, audio system pre-sets, air conditioning preferences, and navigation system settings. In the event both owners use the car at the same time, the RLX will recognize the keyless remote that approaches the vehicle first.

Adaptive Cruise Control with Low-Speed Follow

The RLX Advance features Adaptive Cruise Control (ACC) with Low-Speed Follow. This vehicle speed and distance control system uses a grill-mounted millimeter-wave radar to monitor the distance between the RLX and the vehicle directly ahead. Like a conventional cruise control system, the ACC system can maintain a preset speed. In addition, by combining radar data with data from speed sensors, ACC can regulate the RLX's speed to maintain a preset following distance interval.

The Low-Speed Follow feature can reduce the driver workload in congested traffic by maintaining a selected distance interval, even in stop and go traffic. If a vehicle detected ahead is in range of the system and comes to a stop, the RLX will also come to a stop. When the vehicle ahead moves forward, the vehicle icon on the multi-information display blinks. With a press of the RES/+/SET/– switch up or down, or with a press of the accelerator pedal, the RLX will resume Low-Speed Follow mode.

RLX Interior Accessories

A line of Genuine Acura Accessories was developed simultaneously with the RLX to provide personalization for the Acura owner. Like all Genuine Acura Accessories, the RLX accessories are covered by a 4-year/50,000-mile limited warranty if installed by the dealer at the time of vehicle purchase.

2014 Acura RLX - Visibility Technologies

In addition to the expanded view driver's mirror, multi-angle rearview camera and Jewel Jewel Eye™ LED headlights, the RLX is available with the Blind Sport Information system.

Blind Spot Information (BSI)

The standard Blind Spot Information (BSI) system in the Technology, Krell Audio and Advance grades uses two radar sensors to continually monitor conditions behind the RLX and alert the driver if another vehicle is detected in close proximity – especially in the blind spot of the driver. The BSI system uses the LED indicators (mounted on the A-pillar escutcheon) and an audible warning to alert the driver.
There are two warning levels: 1) If a vehicle is in the driver's blind spot then the LED indicator on the incoming side illuminates; and 2) If a vehicle is detected and the RLX turn signal is activated, the LED indicator on the incoming side blinks and a buzzer sounds three times.
To prevent false alarms while maneuvering at low speed, the BSI system is disabled below approximately 20-mph.

2014 Acura RLX - Safety Technologies

Utilizing a host of advanced active and passive safety technologies, the RLX elevates occupant safety in Acura's flagship sedan. The RLX is anticipated to achieve a 5-Star Overall Vehicle Score from the NHTSA and a TOP SAFETY PICK+ rating from the Insurance Institute for Highway Safety (IIHS), including a GOOD rating in the Institute's new small overall frontal collision test. Its impressive suite of accident-avoidance technologies includes the next-generation Advanced Compatibility Engineering™ II (ACE™ II) body structure, which utilizes a series of interconnected front frame members to absorb and redirect collision energy around the passenger cabin in a frontal collision.

The RLX also makes strategic use of high-strength steel to further enhance collision protection in frontal, side, rear impact and rollover incidents.  The RLX seven, smart-deploying airbags – driver and front-seat passenger front and side airbags, side-curtain airbags, and a driver's knee airbag.  In the Advance trim, the driver and front passenger seats also feature e-pretension seat belts that maintain a low-level of tension (for improved comfort) in normal driving and pre-tension in the event of a collision.

Crash Safety Targets

The 2014 RLX is targeted to achieve the top safety ratings available in America. These include ratings from the federal government's National Highway Traffic Safety Administration (NHTSA) as well as from the privately-owned Insurance Institute for Highway Safety (IIHS).

Based on internal testing, the Acura RLX is anticipated to achieve 5-Star ratings in all NHTSA tests, while also achieving a 5-Star Overall Vehicle Score. In IIHS testing, the RLX is anticipated to achieve a GOOD rating in all tests – include the rigorous new IIHS Small Overlap Frontal crash test that is being implemented for 2013 and newer vehicles – along with a highest-available TOP SAFETY PICK+ overall rating.

Projected test results include:

Structural Safety Advances

Meeting the RLX's top crash-safety rating targets required numerous structural engineering advancements. Details include:

• Frontal – The next-generation Advanced Compatibility Engineering™ II (ACE™ II) body structure helps the RLX pass the more stringent new IIHS Small Overlap Frontal Crash Test with a top "Good" result.
• Side – The use of sophisticated advances in collision load pathways and the use of hot-stamped high-strength steel helps improve occupant protection in side impact scenarios and should lead to top NHTSA and IIHS side-impact ratings..
• Rear – Rear-impact performance meeting the federal FMVSS301 standard is achieved by sophisticated engineering specifications and the use of lightweight high-strength steel.
• Rollover/Roof Strength – The RLX achieves the federal FMVSS216a standard and IIHS Roof Strength "Good" test rating by adopting hot-stamped high-strength steel and optimized engineering specifications.
• IIHS Small Overlap Front (Narrow Offset Barrier) – The Advanced Compatibility Engineering™ II structure integrated into the RLX is expected to aid in the compliance with the new IIHS Narrow Offset Barrier test that begins in 2013.

Next-Generation Advanced Compatibility Engineering™ II (ACE™ II)

The 2014 RLX utilizes the latest version of the proprietary Advanced Compatibility Engineering™ II (ACE™ II) body-structure technology to enhance occupant protection and crash compatibility in frontal collisions. The new design maximizes energy absorption around the engine compartment and minimizes it in the passenger compartment. The new ACE body design is expected to help RLX to pass the extremely difficult new IIHS small overlap frontal collision test, which involves 25-percent of a car's front end on the driver's side striking a 5-foot-tall rigid barrier at 40 mph.

Like the original ACE, the next-generation ACE™ II body structure utilizes a network of connected structural elements – now even more accurately designed and using a greater amount of hot-stamp and high-tensile steel – to distribute and direct crash energy away from the passenger compartment. This enhanced frontal crash energy management helps to reduce the forces transferred to the passenger compartment and can help to more evenly disperse the forces transferred to other vehicles in a crash. Additionally, ACE™ II helps minimize the potential for under-ride or over-ride situations that can happen during frontal impacts with a larger or smaller vehicle.

Unlike most conventional designs that direct frontal crash energy only to the lower load-bearing structures in the front end, ACE™ II actively channels frontal crash energy to both upper and lower structural elements, including the floor frame rails, side sills and A-pillars. By creating specifically engineered "pathways" that help distribute these frontal impact forces through a greater percentage of the vehicle's total structure, ACE™ II can more effectively route them around and away from the passenger compartment to help limit cabin deformation and further improve occupant protection. Integral to the next-generation ACE™ II concept is its unique front polygonal main design structure.

Airbags

A total of seven airbags, including dual-stage, multiple-threshold front airbags, front side airbags, side-curtain airbags with rollover sensors, and a new driver's side knee airbag, are standard on the 2014 RLX.

Driver's Side Knee Airbag (SRS)
New for Acura in the RLX is a driver's side knee airbag designed to increase driver protection in the event of a frontal collision. The knee airbag is contained beneath a panel on the underside of the instrument panel, which is contoured away from the knees to provide as much clearance as possible for comfort.

Dual-Stage, Multiple-Threshold Front Airbags (SRS)
Every RLX is equipped with dual-stage, multiple-threshold front airbags (SRS). One or both of these airbags will be deployed only in the event of a sufficient frontal impact. If deployed, the airbags are capable of being inflated at different rates depending on crash severity, seat-belt usage and other factors. Front airbags are designed to supplement the seat belts to help reduce the likelihood of head and upper body injuries in frontal crashes.

Front Passenger Airbag-Off Indicator
An indicator light marked "PASS AIRBAG," located on the right of the upper display illuminates to indicate that the passenger's front airbag is off and will not deploy during a frontal impact. This happens when the weight of the front-seat passenger, or an object on the seat, is 63.8 pounds or less.

Driver and Front Passenger Side Airbags
Driver's and front passenger's SmartVent™ side airbags mounted in the outboard area of each front seatback are designed to help provide pelvis and thorax protection in the event of a severe side impact. The advanced design allows the side airbags to inflate with a low risk of injuring the seat occupant while deploying. This eliminates the need for the previous-generation RL's Occupant Position Detection System (OPDS).

Side Curtain Airbags with Rollover Sensor
All outboard seating positions include a side curtain airbag system. The side curtain airbags deploy from modules in the roof in the event of a sufficient side impact or rollover, providing a significant level of head protection in the window area. The new side curtain airbags now have a rollover sensor, a wider deployment profile, and remain fully deployed for an extended time to enhance ejection mitigation. This application is two years in advance of new safety regulations going into effect in 2015.

Adjustable Head Restraints for All Seating Positions

All front and rear seating positions feature individually adjustable head restraints. Compared to the Active Head Restraints in the previous RL model, the RLX's front head restraints feature the latest generation of neck protection performance. They are wider, lighter and offer 7mm greater clearance for more driving comfort while also offering superior protection.

The rear head restraints comply with Federal Motor Vehicle Safety Standards (FMVSS) for rear passenger head restraints that took effect for all-new 2011-model-year-and-later vehicle. The new rules closely specify the size, position and operation of the rear-seat head restraints.

Front Seatbelt E-Pretensioners

The RLX Advance model features seatbelt e-pretensioner for both of the front seats that detects yaw rate. During aggressive driving, the e-pretensioner system uses electronic controls to tighten the seatbelts. During normal driving conditions, the e-pretensioner provides a "tensionless" seatbelt experience, enhancing driving comfort.

In addition, the electronic controls of the e-pretensioner seatbelt system tighten and hold the seatbelt when the RLX is being driven in a sporty manner, and also in the event of sudden steering inputs, such as a skid or a light collision. The e-pretensioner system is fully automatic and requires no intervention from the driver or front passenger, aside from the initial extension and fastening of the seatbelt.

Child Safety Features

Two Lower Anchors and Tethers for Children (LATCH) child seat-mounting positions are built into the outboard rear seats. The LATCH system utilizes both an upper child-seat tether anchor and dedicated lower-anchor points that are built into the body of the vehicle. These help ensure correct mounting of a compatible child seat. A third upper tether is located in the rear center position. The RLX also features childproof rear door locks. When engaged, they permit the rear doors to be opened only from the outside, thereby helping to prevent accidental opening by a child.

Forward Collision Warning

The RLX's standard Forward Collision Warning (FCW) system uses a camera mounted in the upper portion of the windshield to detect vehicles ahead and determine if a collision is possible.

A visual "BRAKE" warning on the Multi-Information Display (MID) alerts the driver when the system determines that a collision is possible with a vehicle detected ahead. If the driver does not take any actions to avoid the collision, a second visual warning and an audible warning will alert the driver again. The FCW system in the RLX will not automatically brake, and the driver remains responsible for safely operating the vehicle and avoiding collisions.

Collision Mitigation Braking System™

Collision Mitigation Braking System™ (CMBS™) on RLX Advance trims.4  

Lane Departure Warning (LDW)

The standard Lane Departure Warning (LDW) uses the same upper front windshield camera as the FCW system (Advance grade uses the same camera used by the LKAS system) to visually identify the lanes in the road. If the RLX starts to drift out of a detected lane and into another without a turn signal in use, the system will alert the driver with a visual "LANE" warning in the MID panel, along with an audible warning. The LDW system can be activated and deactivated by a button on the lower left portion of the instrument panel.

Pedestrian Injury Mitigation

The RLX has an impact-absorbing front body design to help absorb energy in the event of a frontal collision with a pedestrian. Research shows that the following features can dramatically improve a pedestrian's chance of survival if struck by a moving vehicle:

• Impact-energy absorbing hood
  Space is provided between the underside of the hood and key powertrain components, allowing the hood to bend and deform if contact is made with either an adult or a child pedestrian.
• Energy-absorbing fender mounts and supports
  Front fender mounts and brackets are designed to deform easily to help absorb impact energy.
• Deformable windshield wiper pivots
  Wiper pivots are designed to deform and break away easily.
