2011 Acura TSX Press Kit

INTRODUCTION

The TSX has long been one of Acura's most popular models. As an all-new, clean sheet design for 2009, the automotive media was immediately impressed and TSX sales were strong. Thanks to a great mix of styling, sporty performance, luxury appointments, good fuel efficiency and outstanding value, the TSX has remained the volume leader within its segment according to Global Insight. Rather than resting on their laurels, Acura engineers have made major updates to the 2011 TSX.

While the TSX sedan receives significant updates for 2011, the big news is an all-new TSX variant-- the TSX Sport Wagon. With crisp styling and added utility, the TSX Sport Wagon is a smart alternative for those considering a compact SUV. Besides offering better fuel economy, the TSX Sport Wagon provides cargo area comparable to that of many CUVs. Plus, the TSX Sport Wagon offers an available power actuated tailgate, a multi-configurable rear cargo area (with numerous hidden storage areas) and a low lift-over height allowing for easy loading. In today's tough economic environment, the time is perfect to offer a smarter choice for buyers-- one without sacrifice or that is a compromise for the needs of today's savvy buyer.

The combination of value, fuel efficiency and technology that make the TSX a smart luxury choice have given the TSX the largest percentage of buyers under 30 among all luxury sedans. The TSX Sport Wagon now offers a smarter choice for young families and those with active lifestyles, wanting added space for utility without having to pay the penalty of the increased size and reduced fuel economy that is common with many SUVs.

30 years ago station wagons ruled the road for hauling the family. For 2011 the wagon returns to again rule the road, but in a smarter package that prioritizes sporty driving and excellent fuel efficiency. Smart luxury-- it's a key element in every Acura model, and it is perfectly illustrated in the all-new TSX Sport Wagon.

However, the Sport Wagon isn't the only thing new, as the 2011 TSX sedan receives a wide array of new features, options, and technology-- with particular attention being paid to further improving quality and reducing noise, vibration, and harshness (NVH). Furthermore, the TSX sedan receives an updated exterior look as well. In short, the best entry luxury car just got better.

On the outside, the 2011 TSX receives a new front fascia and an updated grill that team with new underbody panels to improve aerodynamics. The standard 17-inch 5-spoke aluminum wheels for the I-4 models are more cutting edge as they now incorporate a machined lip on the spokes, and split 5-spoke 18-inch aluminum wheels remain standard for the V-6 model. At the rear, a new garnish around license plate area and revised taillights deliver added visual punch for the 2011 TSX.

Inside, the 2011 TSX receives a host of visual upgrades in the form of revised styling for the center console, darker trim pieces, brightly finished door handles, an updated parking brake handle, new steering wheel garnishes along with contrasting-color stitching for the leather seats, door armrests and center console. Rear seat occupants will enjoy added comfort thanks to the addition of heating/cooling vents mounted at the rear of the center console. The 2011 also makes use of even more LED lighting now including the front footwells.

Acura is known for its outstanding array of user relevant technology, and the 2011 TSX further expands on this concept. New for 2011, the TSX with available Technology Package now includes an LED backlit full VGA navigation screen (that generates 400-percent higher resolution than before), Song By Voice™ (SBV) user interface, a 60-gigabyte hard disk drive (HDD), and the ability to download 15-gigabytes of personal music to the HDD. With the ability to store more than 3,500 songs, there is no longer any need to haul around a stash of bulky CDs.

Acura has always put much emphasis on building an interior that is exceptionally quiet, and for 2011 the TSX has even less noise, vibration, and harshness (NVH) thanks to items such as a new acoustic glass front windshield, even thicker side glass, increased use of sound-deadening insulation, thicker floor mats and new underfloor covers.

The 2011 TSX remains fun to drive thanks to two powerful engine choices; a spirited 2.4L inline four cylinder available on TSX Sedan and Sport Wagon and a torquey 3.5L V-6 available on TSX Sedan. For 2011, both engines receive numerous improvements to reduce internal operating friction which help improve fuel economy. As a result, the friction reduction measures are a significant element to improve fuel economy as (for example) there are improvements in city, highway and combined fuel economy for both the 2.4L I-4 and the 3.5L V-6 for the 2011 TSX models.

Helping maximize the engine output, new automatic transmission programming allows for Shift Hold Control during cornering along with "smart shift" functionality that allows for semi-manual operation when in Drive-- not just when in Sport Mode. In addition, the Sequential SportShift 5-speed automatic transmission now features a fluid warmer that helps improve shift quality and engine fuel economy for TSX owners who live in colder climates.

THE ENTRY PREMIUM MARKET

With a price point typically in the high $20,000 to mid $30,000 range, the "entry premium" segment represents the gateway to luxury for over a dozen automakers. Customers will find the Acura TSX positioned alongside the Audi A4, BMW 3-series, Infiniti G, Lexus IS, Mercedes-Benz C-class and Saab 9-3. With the entry to a luxury brand comes high expectations, and the TSX – together with the award-winning Acura dealership experience – is ready to meet all of them. For 2011, the TSX further raises the performance bar for those looking for additional cargo space and utility while still maintaining ample sportiness. While the TSX sedan with 2.4L I-4 competes with vehicles such as the A4 2.0T, 328i, IS 250, C300 and the new G25, the TSX V-6 targets even more performance minded entry luxury sedans. The TSX V-6 is a strong consideration for customers who will shop the BMW 335i, Lexus IS 350 and Mercedes C350. And now with the availability of the new Sport Wagon, the TSX also competes with the Audi A3 and A4 Avant, BMW 328i Sports Wagon, Saab 9-3 SportCombi and Volvo V50.

TARGET CUSTOMER

The 2011 TSX is designed to appeal to young professionals who are previous TSX owners, conquests from other luxury brands such as Audi, BMW and Lexus, as well as to customers whose income and tastes are moving upscale. Demographically, TSX buyers are expected to range in age from 28 to 34 years old and hold a college degree. These customers are split nearly evenly between male and female, and slightly less than half are married. They are image seekers and will appreciate the styling, technical allure and total performance that the TSX offers – while also valuing the outstanding customer treatment that owners have come to enjoy at Acura dealerships.

The buyer for the TSX V-6 is expected to be older (approximately 38 years old) than the TSX buyer, 80-percent male, 60-percent married, with a household income of about $110,000. Remaining the same is that the TSX V-6 buyer will be extremely brand conscious and eclectic in their tastes and interests.

Buyers for the all-new TSX Sport Wagon are expected to be Gen X individuals, slightly older than TSX Sedan owners who have young families. A secondary buyer for the TSX Sport Wagon will likely be active lifestyle empty nesters.

ENGINE & POWERTRAIN

With the availability of a V-6 powered TSX, Acura filled a niche in its lineup between the four-cylinder TSX sport sedan and the TL performance luxury sedan.

First available in 2010, the TSX could be ordered with a 3.5L SOHC V-6 that develops 280 horsepower and 254 lb-ft of torque. The V-6 features VTEC® valvetrain control, a high 11.2:1 compression ratio and a dual-stage induction system contained within a lightweight magnesium intake manifold. For TSX use, the V-6 is tuned to deliver a more linear torque curve with emphasis on the rpm range most commonly used for day-to-day driving.

The 3.5L V-6 meets California's stringent CARB LEV II ULEV emissions certification and delivers an EPA estimated fuel economy of 19 mpg in city driving and 28 mpg on the highway**-- an increase of 1 mpg in both city and highway driving for the 2011 TSX.

Sporty performance, good fuel efficiency and low emissions are the hallmarks of the TSX's all-aluminum DOHC i-VTEC® inline four-cylinder engine. Displacing 2.4 liters and producing 201 hp and 172 lb-ft of torque (6MT), the inline engine produces its useable power across a wide rpm range, while a broad torque curve further strengthens the engine's pulling power at middle rpm levels. This allows the 2011 TSX to be responsive off the line, out of corners and when overtaking other vehicles.
The performance and flexibility of the 2.4L I-4 is credited to a high compression ratio, precise valve timing, and a high flow intake and exhaust system. Further credit also goes to the TSX's i-VTEC® "intelligent" valve control system. Variable Valve Timing and Lift Electronic Control (VTEC®) combines with Variable Timing Control™ (VTC™) to deliver excellent power. Likewise, a rear-mounted exhaust manifold layout, a close-coupled catalytic converter design and a Programmed Fuel Injection (PGM-FI) system that team to substantially reduce emissions levels, enabling the 2011 TSX to meet the EPA TIER 2 - BIN 5 and CARB LEV II Ultra Low Emission Vehicle (ULEV) standards. Thanks in great part to the new friction reducing upgrades to the 2011 I-4 engine, both the city and highway fuel economy improve by 1 mpg with city/highway combined fuel economy improving by 2 mph versus the 2010 TSX's I-4 engine.

2011 TSX EPA estimated city/highway/combined fuel economy ratings**
TSX model	EPA rating	Improvement (versus 2010 model)
2.4L I-4 (5AT)	22/31/26 mpg	+1 city, +1 highway, +1 combined
2.4L I-4 (6MT)	21/29/24 mpg	+1 city, +1 highway, +1 combined
3.5L V-6 (5AT)	19/28/23 mpg	+1 city, +1 highway, +2 combined

TSX customers who choose the spirited four-cylinder engine have a choice of two transmission styles as standard equipment-- a 6-speed close-ratio manual or a Sequential SportShift 5-speed automatic. The manual transmission features a short-throw shifter with a precise, light action that makes it highly rewarding to use. The manual transmission uses an aluminum case to reduce vehicle mass thus improving all-around performance and efficiency.

For TSX drivers who prefer a more relaxed driving experience, available is a sophisticated Sequential SportShift 5-speed automatic transmission that can be operated manually via steering wheel mounted racing inspired paddle shifters. The smooth shifting automatic is also fitted with intelligent features such as Grade Logic Control and Shift Hold Control, which make driving the TSX on hilly or winding roads more enjoyable.

BODY & CHASSIS

The 2011 TSX features a wide and muscular body which translates into outstanding handling and performance. A wide body (72.4 inches), long wheelbase (106.5 inches) and overall length (185.6 inches) give the TSX sedan excellent ride quality and ample interior space for passengers. The TSX Sport Wagon features a slightly longer overall length (189.2 inches) and taller height (57.9 inches), but still retains the sporty driving characteristics of the TSX sedan.

The TSX uses Showa dual-mode suspension dampers, which provide superior suspension damping characteristics at both lower and higher damper speeds. The TSX employs Electric Power Steering (EPS) that delivers precise input during performance driving, with slightly different tuning for the Sport Wagon model.

Advanced techniques in body design and construction, such as the use of cross-braced roof structure and a strong rear bulkhead, yield a very rigid and vibration-resistant structure. Aerodynamic tailoring included the use of inside frame rails, comprehensive aerodynamic tailoring underneath the car, and the use of A, B and C-pillar separators-- all of which give the TSX a quiet cabin even when on rough roads or at high speeds. The TSX's slippery aerodynamics also helps fuel efficiency as well as high-speed stability, all while lowering emissions.

INTERIOR

Functionality and refinement, luxury and style converge in the interior of the 2011 Acura TSX. Featuring a blend of sweeping shapes, a high level of standard comfort and convenience features, widespread use of premium materials and an available Technology Package, the TSX sports sedan offers an upscale, modern interior that customers have come to expect from Acura. For 2011, the interior features numerous improvements including revised styling for the center console, darker trim pieces, brightly finished door handles, an updated parking brake handle, new steering wheel garnishes along with contrasting-color stitching for the leather seats, door armrests and center console. Rear seat occupants will enjoy added comfort thanks to the addition of heating/cooling vents mounted at the rear of the center console. Plus, the 2011 makes use of even more LED lighting now including the front footwells.

First impressions are powerful, and an initial look inside the TSX reveals much about its character. From the precision crafted metal door sills to the satin-metal finish accents, from the leather-covered seats to the steering-wheel mounted controls, and from the premium 7-speaker audio system to the dual-zone automatic climate control, the TSX represents a merge of intelligent design and innovation. Bluetooth® connectivity is standard and includes HandsFreeLink® cellular telephone interface that makes communications easier while en route. The TSX's Keen-Edgedesign blends perfectly with its range of electronic features in a way that makes the driving experience more satisfying.

Adding to the already impressive list of TSX standard equipment is the available Technology Package, which bristles with leading-edge electronics that make driving that much more efficient and enjoyable. The Acura Navigation System with Voice Recognition™, AcuraLink Real-Time Traffic™ and AcuraLink Real-Time Weather™, and the highly useful AcuraLink® Satellite Communication System are the centerpieces of the Technology Package. Also part of the Technology Package is a rear view camera that now includes the availability of showing gridlines (driver can turn off function if desired) that help with alignment when backing up.

The navigation system features continuously updated traffic maps covering 109 major metropolitan areas within the United States (three metropolitan markets within Canada), and offers Traffic Rerouting™ to help navigate around slow-downs. New for 2011 is a 60-gigabyte hard disk drive (HDD) for the navigation and audio systems. Besides offering impressive response time (much faster than the 2010 system), the HDD offers the ability to download 15-gigabytes of personal music.

Also part of the available Technology Package is a 10-speaker premium audio system tuned by legendary recording engineer and producer Elliot Scheiner. The Acura/ELS Surround® Premium Audio System includes a Note function for XM® Radio that makes it easy to identify songs to recall at a later date. With push of a button, the Note function can capture 10 seconds each of up to 30 songs, along with text indicating song title, artist name and XM® Radio channel. New for 2011 is Song by Voice™ (SBV) that allows the driver to select audio choices via voice activation, rather than having to remove a hand from the steering wheel.

Another benefit of the new HDD navigation system is expanded Bluetooth functionality including more actions that can be made via interface dial rather than just using voice commands.

The all-new TSX Sport Wagon features an even greater level of utility over the TSX sedan. Besides offering a generous 60.5 cu-ft of rear cargo area (with rear seats folded down; 25.8 cu-ft with the seats up), the wagon’s rear opening height of approximately 28-inches allows for the stowage of bulky items such as large boxes, furniture, bicycles, four full-size golf bags and even surfboards.

SAFETY

Providing an array of advanced safety features is among the highest priorities of the 2011 Acura TSX. Leading the way is the TSX's Advanced Compatibility Engineering™ (ACE™) body structure. ACE™ improves the dispersal of frontal crash energy via load-bearing frame structures that also better match the TSX with other vehicles of different sizes and with different bumper heights. In doing so, ACE™ helps reduce the frontal crash forces before they reach the passenger compartment.

Contributing to the safety performance of the 2011 TSX is a broad range of passive safety features, including six airbags (dual-stage, multiple-threshold front airbags, dual-chamber front seat side airbags, and side curtain airbags for outboard seating positions).

TSX driver and front passenger are further protected thanks to active front head restraints and front seatbelts with an integrated automatic tensioning system and load limiters. The rear seat features a Lower Anchors and Tethers for CHildren (LATCH) system with built-in lower anchors and ready-to-use tether attachment points that allow compatible child safety seats to be installed without using the vehicle's seat belt system.

Exterior features designed to further improve safety include daytime running lights (DRL) along with pedestrian injury mitigation technologies such as a deformable hood panel, hood hinges and windshield-wiper pivots.

2011 Acura TSX - Powertrain

INTRODUCTION

The most significant change to the TSX powertrain for 2011 is the use of numerous friction reducing technologies applied to both the 2.4L I-4 and the 3.5L V-6 engines. The reduction of internal operation friction enables the two engines to deliver improved and class-leading fuel efficiency.

Both the 4- and 6-cylinder engines make use of a new plateau honing technique for the cylinder bores that generates a smoother surface. As a result, the piston rings achieve more consistent contact with the cylinder walls which generates improved ring-to-bore sealing along with reduced overall friction.

With the 2.4L I-4, the pistons make use of a new low-tension piston ring that reduces operating friction while the 3.5L V-6 uses a redesigned ion-plated piston ring design. In addition, the outer skirts of both the 4- and 6-cylinder pistons now feature a molybdenum coating applied in a unique dot-pattern application. The result is reduced overall friction as the pistons move within the cylinder bores.

Other friction reducing items include the use of lower viscosity engine oil (0W-20 weight versus the previous 5W-20 weight oil) along with lower viscosity oil for the Sequential SportShift 5-speed automatic transmission. In addition, the 5-speed automatic fitted to the 2.4L I-4 engine now makes use of a new fluid warmer assembly warmer that helps improve shift quality and engine fuel economy for TSX owners who live in colder climates.

For 2011, the 2.4-liter DOHC i-VTEC® inline four-cylinder engine remains as the standard engine. The engine offers good acceleration while generating excellent fuel efficiency. The all-aluminum I-4 engine produces 201 hp and 172 pound-feet of torque (6MT), and incorporates Acura’s i-VTEC® "intelligent" valve control system that features Variable Valve Timing and Lift Electronic Control (VTEC®) combined with Variable Timing Control™ (VTC™). Though peak horsepower is virtually unchanged versus the previous generation 2.4L engine, peak torque output has risen by 8 lb-ft. In addition, the engine’s torque curve has fattened considerably. Horsepower, for example, is up five percent at 4,400 rpm. The result is stronger throttle response and better acceleration just about everywhere in the engine’s operating range. To achieve these power gains, the engine has a higher compression ratio, new valve timing, and intake and exhaust flow improvements. An aluminum and resin composite intake manifold reduces weight over the previous I-4’s aluminum design, while better insulating the engine’s incoming airflow from under-hood heat.

A rear-mounted exhaust system layout, close-coupled catalytic converter and advanced Programmed Fuel Injection (PGM-FI) team to help both the I-4 and V-6 engines meet EPA 2 - Bin 5 and CARB LEV II Ultra Low Emission Vehicle standards.

Beginning in 2010, the TSX was available with a transversely mounted 3.5-liter all-aluminum V-6 engine with single overhead camshaft (SOHC) cylinder heads. The V-6’s 12 intake valves are actuated by Acura’s acclaimed VTEC® (Variable Valve Timing and Lift Electronic Control) system. The compact and efficient V-6 engine produces 280 horsepower and 254 lbs-ft of torque. The power curve has been specially tailored to deliver strong, linear power in the rpm range used in most day-to-day driving conditions.

The 2011 TSX with 2.4L I-4 engine comes with a choice of two transmissions-- a close-ratio 6-speed manual transmission (Sedan only) or a Sequential SportShift 5-speed automatic transmission. The manual gearbox has a lightweight aluminum alloy case and multi-cone synchronizers providing a light, quick action with very short shift throws. To provide more spirited driving, the manual transmission includes performance-minded gear ratios to maximize acceleration during spirited driving.

The Sequential SportShift 5-speed automatic transmission has a straight-style shift gate with Drive and Sport positions that provide fully automatic operation. At the driver’s option, the automatic transmission can be shifted manually via steering wheel mounted paddle shifters. Grade Logic and Shift Hold Control work in automatic mode to keep the transmission in the gear that is ideal for the current driving situation. Further improving performance and drivability is a revised torque converter lock-up assembly.

100,000-mile tune-up intervals and a standard Maintenance Minder™ system (which automatically monitors the vehicle’s unique operation condition to indicate to the driver when maintenance is required) help to lessen the cost of ownership. The Maintenance Minder™ system is designed to ensure that important service issues are addressed in a timely manner, and eliminate unnecessary maintenance procedures to help reduce environmental impact and operating expenses.

ENGINE BLOCK

The TSX’s 3.5-liter V-6 engine uses an inherently smooth-running 60-degree V-angle. The engine block is constructed of lightweight die-cast aluminum and uses thin-wall iron liners that are made in a centrifugal spin-casting process that ensures high strength and low porosity. The rough outer surface of these liners makes an effective bond with the aluminum block, enhancing block stiffness and heat transfer from the cylinder liners to the block. For 2011, the cylinder liners are now finish honed using a new plateau honing technique that generates a much smoother surface that translates to improved ring-to-bore sealing along with reduced operating friction.

The 3.5-liter cylinder aluminum block is heat-treated for strength and has deep-skirt designs with four bolts per bearing cap (providing excellent structural support for the crankshaft), thus minimizing engine noise and vibration.

The 2.4L I-4 uses a die-cast lightweight aluminum cylinder block with cast-in iron cylinder liners that are made using a unique spin casting, centrifugal process. Like the 3.5L V-6, the inline four uses Acura’s new plateau honing technique. For maximum rigidity and minimal noise and vibration, the cylinder block is a 2-piece design that supports the five main bearings with a single cast-alloy bed-plate assembly.

CRANKSHAFT/CONNECTING RODS/PISTONS

The 3.5-liter engine employs a robust forged-steel crankshaft for high strength and minimum weight. Forged aluminum 11.2:1 pistons are used and are cooled with oil spray directed to the underside of the piston crowns, making possible the high compression ratio. The pistons feature a new MoS2 molybdenum coating applied in a unique dot-pattern application that reduces overall friction as the pistons move within the cylinder bores. The connecting rods are steel forgings for high strength, and are crack-separated-- a unique process in which the bearing caps are broken apart from the rod rather than machined separately. This process forms a lighter, stronger connecting rod with exact mating surfaces.

The four-cylinder uses a high strength forged-steel crankshaft with micropolished journals to help reduce friction and to improve long-term durability. High compression 11:1 aluminum pistons feature the new MoS2 molybdenum coating and also use a new design of low-friction rings to help reduce friction.

CYLINDER HEADS/VALVES

The 3.5-liter engine has lightweight aluminum cylinder heads that are pressure cast for high accuracy and low porosity. To save weight and reduce parts count, these cylinder heads have uniquely integrated exhaust-port castings that provide optimal positioning for close-coupled catalytic converters-- one on each cylinder bank. This design results in more rapid "light off" of the catalytic converters for reduced emissions during cold start-up. The cylinder heads are sealed to the block with a special 3-layer shim-type head gasket.

The 2.4L I-4 cylinder head is constructed of pressure-cast aluminum and features four valves per cylinder actuated by dual overhead camshafts (DOHC). The cams are driven by an automatically adjusted silent-type chain. The chain system is maintenance free and runs in an oil bath for maximum durability. The combustion chambers have large "quench" areas to promote faster flame propagation and more complete burning, thus helping to reduce carbon monoxide (CO) and hydrocarbon (HC) exhaust emissions. Large intake and exhaust valves along with high-flow ports contribute to excellent engine breathing. Additionally, a high compression ratio of 11.0:1 is a significant contributor to the TSX’s torque output.

VTEC® VALVE CONTROL SYSTEM

The 3.5-liter V-6 engine uses the Variable Valve Timing and Lift Electronic Control (VTEC®) system that provides crisp throttle response, strong low-speed torque and enhanced high-rpm power. This is achieved by providing reduced intake valve lift and duration at low engine speeds for good torque, with increased valve lift and longer duration at higher speeds for optimum power. With the VTEC® system, both intake valves are controlled by a single low-speed camshaft lobe.

On the V-6, at 4,750 rpm the Powertrain Control Module (PCM) electronically triggers the opening of a spool valve that routes pressurized oil to small pistons within the intake valve rocker arms. Moved by this pressurized oil, these pistons lock together each cylinder’s intake rocker arms, which then follow in unison a single high-lift, long-duration cam lobe. Intake valve lift and opening duration are adjusted according to engine speed, resulting in a broad torque curve as well as superior power at peak rpm.

The 2.4L I-4 engine features Acura’s i-VTEC® "intelligent" valve control system that pairs Variable Valve Timing and Lift Electronic Control (VTEC®) with Variable Timing Control™ (VTC™). A patented VTEC® design uses three reduced-thickness aluminum rocker arms that operate a pair of valves for each cylinder. At low rpm, the intake valves follow low-lift, short duration camshaft profiles to help boost low-end torque. Above 5,000 rpm, the valves are operated by high-lift, long-duration camshaft profiles for maximum high-rpm horsepower.

To further refine the I-4’s operation, the engine features an "intelligent" element that adds Variable Timing Control™ (VTC™) to VTEC® which provides continuously variable, computer controlled camshaft timing. In total, the I-4’s i-VTEC® system provides performance, efficiency and emissions benefits by allowing the intake valve lift and valve timing to be continuously adjusted to suit the engine's operating parameters.

Variable Timing Control™ (VTC™)

With the 2.4-liter engine, intake camshaft timing is continuously adjusted to suit engine operating conditions via a system called Variable Timing Control™ (VTC™). An integral part of the i-VTEC® system, the VTC™ enhances power output, fuel efficiency and emissions performance with its precise control of camshaft timing.

Camshaft position, intake manifold pressure and engine rpm are simultaneously monitored by the powertrain control unit (PCM), which then commands a VTC™ actuator to advance or retard the intake camshaft timing. The intake camshaft is almost fully retarded at idle to deliver more stable idle and reduced hydrocarbon (HC) emissions. As engine RPM builds, the intake camshaft is progressively advanced so the intake valves open sooner and valve overlap increases. Such operation reduces pumping losses, which increases fuel efficiency and further reduces exhaust emissions due to the creation of an internal exhaust-gas recirculation effect.

INDUCTION SYSTEM

The 3.5L V-6 features a dual-stage intake manifold made from lightweight magnesium alloy. The manifold works together with VTEC® to improve low-speed torque with no sacrifice in high-rpm power. Divided into two banks feeding three cylinders per bank, the manifold has two Powertrain Control Module-controlled valves located between each bank. These valves are closed at low engine speed, which reduces the operating volume of the plenum and increases the effective length of the inlet passages. The result is maximum resonance effect and amplification of pressure waves within each half of the manifold at lower engine speeds, significantly increasing cylinder filling and low rpm torque. The open ends of the intake runners are also flared into a "trumpet" shape (as on racing engines) to further improve airflow.

At 3,950 rpm the valves open, connecting the two halves of the manifold, increasing its effective volume and increasing the mass of air rushing down each intake passage. The inertia of this increased air mass forces more charge into each cylinder for better cylinder filling, increasing power at high rpm. The manifold’s two modes further complement the changes in low and high speed running made possible by the VTEC® system.

The induction system used with the 2.4L I-4 is designed for high flow as well as to create an aggressive sound. The inlet design allows cool ambient air to be picked up at the front of the vehicle, and then routed though a high-flow air filter assembly. The single-stage lightweight plastic intake manifold has fixed-length intake runners that are tuned in length, diameter and shape to provide an optimal blend of low-rpm torque and high-rpm response. The composite manifold incorporates 48 mm intake runners along with a high flow aluminum throttle-body.

PROGRAMMED FUEL INJECTION (PGM-FI)

Both the I-4 and V-6 engines feature Programmed Fuel Injection (PGM-FI) that uses an array of sensors to constantly monitor a number of critical operating variables, including throttle position, intake air temperature, water temperature, ambient air pressure (altitude), air flow, air/fuel ratio, along with the position of the crankshaft and camshafts. Highly vaporized-style fuel injectors reduce the typical size of fuel droplets, which improves air/fuel atomization and flame propagation inside the combustion chambers.

MULTI-HOLE FUEL INJECTORS

Special multi-hole fuel injectors mounted in the lower intake manifold spray directly toward the intake ports. The multi-hole injector design means that fuel droplet size is reduced for better fuel atomization, resulting in improved cold weather start-up, better fuel efficiency and higher horsepower.

DRIVE-BY-WIRE™ THROTTLE SYSTEM

In place of a conventional mechanical throttle linkage setup, the TSX uses a Drive-by-Wire™ throttle system. The result is more accurate and precise throttle control, along with reduced weight and less clutter under the hood. A DC motor controls the amount of throttle-body opening that leads to the intake manifold. This allows the ratio between pedal movement and throttle motion to be altered to suit the specific driving conditions. The system monitors throttle pedal position, throttle-body opening amount, road speed, engine speed (rpm) and engine vacuum. This information is used to define the throttle control sensitivity. The system also alters throttle response based on the calculated road slope, providing more throttle gain uphill and less downhill. When driving on curvy roads, the Drive-by-Wire™ throttle system recalibrates throttle gain to make the TSX easier to control.

In addition, the Drive-by-Wire™ throttle system works with the Sequential SportShift 5-speed automatic transmission to make gear shifts smooth and quick. With coordination of the throttle opening and the transmission's shifting functions, shift shock and shift delay are reduced.

ONE-TOUCH STARTER SYSTEM (TSX V-6)

A TSX fit with the available 3.5-liter V-6 features a starter with more power to crank the larger engine. In addition, the TSX V-6 has a one-touch starter system that automatically maintains starter engagement until the engine has started. The TSX driver simply activates the starter switch once by turning the key and needs not hold the switch in the Start position. Once the V-6 engine starts, the one-touch system disengages the starter automatically.

EXHAUST SYSTEM

The TSX 3.5-liter V-6 has exhaust manifolds that are cast directly into the cylinder heads for reduced weight, parts count and bulk. Attached directly to the cylinder heads are high-efficiency catalytic converters. Due to closer-than-normal proximity to the exhaust ports, the close-coupled catalytic converters "light off" very quickly after the engine starts, reducing emissions during the critical start-up mode. To ensure optimum flow and low backpressure, a hydroformed two-into-one collector connects the close-coupled catalytic converters to the main under-floor catalytic converter.

Downstream of the under-floor converter, the V-6 engine has a single pipe that feeds to a pair of resonators, followed by a pipe split that connect to a pair of high-flow mufflers fit with round exhaust tips. With the V-6, the exhaust system is tuned to deliver a sportier, more aggressive exhaust note than with the 2.4L I-4.

To help boost engine torque, the 2.4L I-4 has a high-flow, low back-pressure exhaust system. Large-diameter pipe sizes throughout the exhaust system increase flow; beyond the under-floor catalytic converter, the exhaust system passes through a pre-chamber (located under the second-row floorboards), and then splits just behind the rear axle to feed into free-flowing dual silencers fitted with chrome exhaust tips.

Emissions control

The 2011 TSX is compliant with the California Air Resources Board (CARB) LEV II ULEV standard, which is one of the toughest emissions regulations in the United States. The TSX also achieves EPA TIER 2 - BIN 5 regulations emissions compliance.

Acura’s advanced technologies contributing to this performance are the close-coupled catalytic converters which light-off quickly on start-up, an increased amount of EGR gas recirculated into the engine, and an advanced 32-bit RISC microprocessor within the Powertrain Control Module (PCM) that boosts computing power to improve the precision of fuel and spark delivery at all engine speeds and conditions. Particularly in the critical post-startup mode, the high-efficiency multi-hole fuel injectors deliver better fuel atomization for lower emissions.

Both TSX engines feature Programmed Fuel Injection (PGM-FI) that continually adjusts fuel delivery to achieve the best combination of power, fuel efficiency, and low emissions. The fuel injectors help reduce exhaust hydrocarbons after engine startup, while a linear air/fuel sensor positioned in the exhaust system just upstream of the catalyst improves air/fuel mixture control.

The inline four-cylinder engine is designed with emissions performance in mind, employing Variable Timing Control™ (VTC™) and a unique i-VTEC® cylinder head design promoting exceptional internal exhaust gas recirculation, which helps reduce NOx emissions output.

Both the V-6 and I-4 engines feature an exhaust manifold design that is integrated directly into the cylinder head casting. This unique design allows the catalytic converter to be positioned very close to the cylinders for swift converter light-off after a cold engine start. A secondary catalytic converter is positioned downstream under the passenger compartment floor.

DIRECT IGNITION AND DETONATION-KNOCK CONTROL

A strong ignition spark is critical to improve power and reduce emissions. Thus, both the 2.4L I-4 and 3.5L V-6 engines feature a direct ignition system that uses individual coil units positioned directly above each spark plug. Because accurate ignition spark timing is crucial for best power and torque output (as well as reduced emissions), the Powertrain Control Module (PCM) continually monitors several engine parameters to determine optimum spark timing based on specific driving conditions.

Additionally, a block-mounted acoustic detonation (knock) sensor "listens" to the engine, sending information about potentially damaging detonation to the PCM, which then incrementally retards ignition timing as needed to help prevent damage.

NOISE, VIBRATION & HARSHNESS (NVH) CONTROL

The 3.5L V-6 is designed to effectively control noise, vibration and harshness (NVH). Featuring a high-rigidity die-cast engine block with 60-degree V-angle cylinders, a strong forged-steel crankshaft, die-cast accessory mounts and stiff cast aluminum engine oil pan, low engine NVH is ensured. The induction and exhaust systems are designed to emit a refined and quiet tone at low speeds, with a sporty "growl" above 3,000 rpm.

The 2.4L I-4 engine has an array of features designed to reduce NVH. The pressure-cast cylinder block has a bed-plate type main bearing cap that results in a highly rigid assembly, which helps to resist vibration. Two balance shafts further smooth the inherent vibration commonly found with a large-displacement inline four-cylinder engine layout. A self-adjusting, silent-type camshaft drive chain and serpentine accessory drive belt team to help reduce NVH.

eLECTRONIC Control MOUNT (ecm)

Acura’s sophisticated Electronic Control Mount (ECM) system is used to minimize the effects of engine vibration. At low engine speeds, vacuum-controlled engine mounts allow additional engine movement, so that less low-frequency vibration is transmitted to the body. At higher rpm, the ECM mounts stiffen so that the mass of the engine is properly restrained for better handling.

With the 3.5L V-6, in addition to being used for the engine, ECM mounts are also used for the Sequential SportShift 5-speed automatic transmission.

ENGINE COMPARTMENT COVER

While the engine compartments for both TSX models are handsomely finished, the 3.5L V-6 features an engine compartment cover that conceals accessory systems. The engine itself is visible and is finished to eliminate the need for traditional cosmetic covers. Whereas the 2.4L I-4 TSX uses a prop rod to hold open the hood, the 3.5L V-6 TSX makes use of a gas-charged strut assembly to hold open the hood. The strut setup not only delivers an improved underhood appearance, but it helps lift the hood during opening as a convenience to the user.

100,000 MILE TUNE-UP INTERVAL

All TSX models are exceptionally low-maintenance automobiles. With features like Iridium alloy-tipped spark plugs and a space-saving, self-tensioning serpentine accessory drive belt assembly, both TSX engines require no scheduled maintenance until 100,000 miles (exclusive of periodic inspections and normal replacement of fluids and filters). The first scheduled service at 100,000 miles includes valve adjustment, timing belt replacement and water-pump inspection. Note that 100,000-mile tune-up interval does not apply to fluid and filter changes. Exact mileage is determined by actual driving conditions.

Maintenance Minder™ SYSTEM

All TSX models feature as standard equipment a Maintenance Minder™ system automatically monitors the vehicle's operating condition. The driver is alerted via a message on the Multi-Information Display (MID) when maintenance is required. The system helps eliminate unnecessary service stops, while ensuring that the vehicle is properly maintained.

The Maintenance Minder™ system monitors operating conditions such as coolant and oil temperatures along with engine speed, and then determines the proper service intervals. Depending on the engine operating conditions, oil change intervals can be extended to a maximum of 10,000 miles, potentially sparing the owner considerable money and inconvenience over the life of the vehicle.

The Multi-Information Display (MID) shows the remaining percentage of engine oil life, and indicates when service is due via a wrench icon. A percentage-based countdown to the next service is displayed when the car is within 15-percent of the end of the service interval. The type of service required is shown in an alphanumeric code, and if a service is missed, the MID indicates its urgency by showing past-due mileage. The system can be reset manually by the owner, and monitors all normal service parts and systems, including oil and filter, air-cleaner, tire rotation, automatic transmission fluid, coolant, spark plugs, timing belt, brake pads and more. Maintenance alerts are presented on the instrument cluster when the ignition is first turned on, and not while driving.

TRANSMISSIONS

SEQUENTIAL SPORTSHIFT 5-SPEED AUTOMATIC TRANSMISSION

All TSX models are available with a smooth shifting Sequential SportShift 5-speed automatic transmission. Although similar in design, the transmission fit to the V-6 engine is more robust to handle the substantial increase in horsepower. In addition, the transmission uses special gear ratios to take advantage of the V-6’s abundant torque. Although the I-4 and V-6 use different transmission gear ratios, the operation of the Sequential SportShift 5-speed automatic transmission is identical. Both Sequential SportShift 5-speed automatic transmissions feature racing-inspired paddle shifters (mounted on the backside of the steering wheel) and Grade Logic Control to maximize acceleration, fuel efficiency and driver control.

Automatic mode
A console mounted, 5-position shift gate makes operation of the transmission simple. When in the "D" position, the transmission operates automatically (selecting from one of the five forward gears) based on the driving conditions. When in automatic mode, the transmission incorporates advanced Grade Logic Control and Shift Hold Control, both of which work to reduce gear "hunting" on hills or when the TSX is in the midst of a turn.

Grade Logic Control reduces shift frequency and improves vehicle speed control by altering the transmission's shift schedule when traveling uphill or downhill. The transmission computer continuously compares throttle position, vehicle speed and acceleration/deceleration with a map stored in the computer memory. The Grade Logic Control System determines when the TSX is on an upslope or down slope. The shift schedule is then adjusted to automatically hold the transmission in a lower gear for better climbing power or increased downhill engine braking.

When the throttle is quickly released and the brakes are applied, as might be the case when decelerating for a corner, Shift Hold Control keeps the transmission in its current (lower) gear ratio. This helps provide added engine braking, and ensures that abundant power is immediately available at the corner exit.

Manual mode
The TSX is equipped with paddle shifters (mounted to the back side of the steering wheel) that operate the Sequential SportShift 5-speed automatic transmission. The paddle shifters are activated with a fingertip pull; the right paddle commands an upshift while a pull of the left paddle commands a downshift. A digital display in the tachometer face indicates which gear the transmission is in when the steering wheel paddles are active.

The steering wheel paddles can operate in both the "D" and "S" transmission positions. When in "D," a touch of a paddle shifter temporarily places the transmission in manual mode (but without gear holding at redline). After steady-state cruising conditions are detected, the transmission returns to fully automatic operation. In "S," engaging a paddle shift enables transmission gear holding, which allows only driver-commanded shifts, with the exception of automatically shifting to First gear at a stop-- even if not driver-selected.

When first placed in "S" mode, the transmission will automatically shift between First, Second, Third and Fourth gears until a paddle shifter is activated. When a paddle shifter is activated, the transmission goes into full manual mode and upshifts will only be made if commanded by the driver.

Manual mode protective features
To help protect the engine and drivetrain from damage, an array of protective features are active when the transmission is in manual mode. The Powertrain Control Module (PCM) will cut fuel flow to the engine if there is a possibility of over-revving in a specific gear, as might occur if the driver is late in commanding an upshift. To prevent over-revving while downshifting, the transmission will not execute a driver-commanded downshift that would send the engine beyond redline in the lower gear. Even if the driver allows the vehicle to come to a stop in a high gear, the transmission will automatically downshift to First gear to prevent lugging away from a stop in a high gear.

5-Speed Automatic Transmission Gear Ratio Comparison
	5AT (I-4 engine)	5AT (V-6 engine)
1st Gear	2.652:1	2.697:1
2nd Gear	1.614:1	1.606:1
3rd Gear	1.082:1	1.071:1
4th Gear	0.773:1	0.693:1
5th Gear	0.566:1	0.490:1
Reverse	2.000:1	1.888:1
Final Drive	4.44:1	4.31:1

Cooperation between Automatic Transmission & Drive-by-Wire™ Throttle System

With the TSX's electronically-controlled Sequential SportShift automatic transmission and Drive-by-Wire™ throttle system, the function of the engine and transmission are closely choreographed for faster, smoother shifting. As a result, shift shock is reduced significantly during shifts.

ACTIVE LOCK-UP TORQUE CONVERTER
To provide good fuel efficiency while maintaining a high level of drivability, the 5-speed automatic transmission includes an active lock-up torque converter. With the precise control afforded by a linear solenoid and assist spring, the system features a wide range of speed and throttle settings in which lock-up assembly can be engaged in the top four gears. This results in improved fuel efficiency for both city and highway driving.

6-SPEED MANUAL TRANSMISSION

Available with the TSX sedan with 2.4L I-4 is a close-ratio 6-speed manual transmission. With precise and light shifting action, the manual gearbox is designed to compliment the TSX’s sporting side. Compared to a 5-speed transmission, the 6-speed gearbox allows for closer gear ratio spacing. Such tighter gear spacing enables the engine to operate closer to its power peak during acceleration for better performance.

The compact, highly rigid transmission case is cast of aluminum alloy to reduce weight. Additionally, the highly rigid casting helps damp out noise and vibration. Multi-cone synchronizers on First through Fourth gears reduce and smooth shifting effort. A high (numerically low) top gear ratio allows for a relaxed cruising rpm, improved fuel efficiency and lower emissions.

The close-ratio 6-speed manual transmission teams with a specially designed clutch pedal assembly that delivers low-effort actuation and has a broad engagement band for progressive engagement and smoother launches.

2011 Acura TSX - Body

INTRODUCTION

The 2011 TSX reflects Acura's advanced design direction. Forceful and muscular but at the same time sleek and elegant, the revised styling clearly sets the tone for the TSX's driving dynamics— agile and invigorating for performance oriented drivers, yet quiet and comfortable for those with luxury intentions.

BODY OVERVIEW

The 2011 Acura TSX's updated body design represents the latest direction in Acura styling. The TSX was styled in Acura's Wako design studio (located just outside Tokyo, Japan) and is assembled at the Sayama Factory in Japan. The 2011 TSX exterior receives a new front fascia and an updated grill that team with new underbody panels to improve aerodynamics. The standard 17-inch 5-spoke aluminum wheels for the I-4 models are more cutting edge as they now incorporate a machined lip on the spokes, and split 5-spoke 18-inch aluminum wheels remain standard with the V-6 package. At the rear, a new garnish around license plate area and revised taillights deliver added visual punch for the 2011 TSX.

Advanced aerodynamic treatments such as inside frame rails, new (larger) underbody air deflectors, a redesigned chin spoiler and a chiseled aerodynamic body shape help the TSX move with a minimum of drag— thereby reducing fuel consumption and lowering emissions output, while simultaneously enhancing interior quietness and high-speed dynamic stability.

While the TSX sedan receives significant updates for 2011, the big news is an all-new TSX variant— the TSX Sport Wagon. With crisp styling and added utility, the TSX Sport Wagon is a smart alternative for those considering a compact SUV. Incorporating a unique high-rigidity rear body structure with a special hoop-style cross section, the TSX Sport Wagon simultaneously provides excellent body strength (for impressive handling performance) along with good crash safety.

The TSX's dynamic styling is designed to appeal to a wide range of customers. These customers lead an active lifestyle, and often participate in outdoor activities. Thus, they want a vehicle that reflects their passion for performance and athleticism while also supporting their active social lifestyle with roomy, comfortable seating for five. Of special note, with 60.5 cubic feet of cargo area, the TSX Sport Wagon offers exceptional utility for owners who lead an active lifestyle.

KEEN-EDGED STYLING

The TSX features Acura's signature design language known as Keen Edge Styling. In keeping with this styling language, Acura designers infused crisp, dynamic design elements into the exterior design of the TSX. Additionally, the TSX's aerodynamic design evokes both emotion and tension with a decisively sporty flair— as if a solid piece of billet material was shaped with a sharp knife.

The 2011 TSX features an updated version of Acura's signature grille along with updated headlights. Fog lamps are now better integrated in the outer edges of the front fascia and remain as a standard feature on the TSX. Keen eyes will notice that the TSX V-6 makes use of a slightly redesigned front bumper assembly that features added air intake openings for improved cooling of the V-6 model's oversized radiator.

Sharp contour lines run alongside the body and connect the front and rear of the new car together in a strong, windswept line that promises both agility and performance. Bold wheel arches that frame the refinished five-spoke, 17-inch aluminum wheels (TSX I-4) or split five-spoke, 18-inch aluminum wheels (TSX V-6) emphasize strength and muscularity. Chrome door handles and chrome trim surrounding the side windows adds a look of substance and quality.

In back, updated taillights compliment large turn signals at the outside edges of the trunk lid. Although similar in look, the TSX Sport Wagon uses unique taillights. Twin reflectors are low-mounted on the rear fascia near the 3.2-inch diameter exhaust finishers.

WIDE BODY DIMENSIONS

The body width for the 2011 TSX is a full three inches wider than the previous-generation TSX. This increase, along with the 2.6-inch wider track and the 1.4-inch longer wheelbase, considerably improves interior roominess. There is a dynamic upside to the wider track: enhanced handling agility and stability. The seating position is also 0.4-inch lower than in the previous generation TSX, offering increased headroom and helping to create a sportier driving experience.

Body Dimension Comparison (Sedan models)
	Acura TSX	Audi A4	BMW 3-Series	Lexus IS	Mercedes C-Class
Length, in.	185.6	185.2	178.2	180.3	182.3
Width, in.	72.4	71.9	71.4	70.9	69.7
Height, in.	56.7	56.2	55.9	56.1	56.3
Wheelbase, in.	106.4	110.6	108.7	107.5	108.7
Track, F/R, in.	62.2/62.2	61.6/61.1	59.1/59.6	60.4	60.7/60.8

SLIM A-PILLARS

To improve the field of view for the driver, the TSX has exceptionally thin A-pillars which permit a broader field of forward view without compromising structural strength. At 4.2 inches wide in their interior dimension, the A-pillars are an inch narrower than the previous TSX A-pillars. The use of thin A-pillars allows for best in class outward frontal field of view.

CLOSED-CHANNEL CROSS-BRACED ROOF STRUCTURE

The TSX uses a strengthened roof section designed to significantly reduce flexing and vibration, resulting in less noise in the passenger compartment. Whereas the roof section on the previous TSX used open-channel stiffeners, the 2011 TSX's roof section uses two closed-channel crossbeams that help create a structure that is highly resistant to flexing and vibration.

The installation method of the roof structure is unique as well. With the previous TSX, the roof panel and its open-channel stiffeners were welded onto the rest of the unit body as a unit. With the 2011 TSX, the roof frame assembly is first welded in place without the roof panel, allowing full access to the ideal welding locations. The roof panel itself is then attached. This process creates stronger joints and a stiffer overall roof and body structure— 35 percent greater rigidity in front and 20 percent greater rigidity in back. The end result for the TSX owner is markedly decreased noise and vibration inside the car.

In addition, the new TSX Sport Wagon incorporates a unique high-rigidity rear body structure with a special hoop-style cross section. This robust build design is lightweight yet provides excellent body strength (for impressive handling performance) along with good crash safety.

FRAME RAIL SYSTEM

The TSX uses an internal frame rail system for reduced aerodynamic turbulence and drag. In addition by positioning the stamped steel frame rails above the floor of the passenger compartment (instead of below it) the bottom of the vehicle can be made much flatter resulting in a quieter ride at highway speeds.

AERODYNAMICS

Careful attention to airflow management helps increase fuel efficiency, reduce emissions and improve stability at higher speeds and in strong crosswinds. Visible elements of the TSX's aerodynamically efficient body design include flush mounted headlights, hidden windshield wipers and flush mounted side and rear glass.

For 2011, the updated front bumper assembly and redesigned chin spoiler team for a 5-percent improvement in aerodynamics while new underbody panels deliver both improved aerodynamics and lower NVH. In addition, the improved aerodynamics of the 2011 TSX reduce lift and improve high speed stability compared to the 2010 model.

Underbody aerodynamic aids include:

A short, wide wickerbill underneath the front fascia helps separate the airflow and allows it to move underneath the engine and transmission with less drag.
A large aluminum and plastic undercover further improves airflow beneath the engine and transmission.
New, exceptionally long underbody covers smooth under-car airflow while simultaneously helping to dampen road and wind noise within the interior.
A pair of deep air “strakes” are located in front of the front tires to help air flow efficiently around the tires.
A pair of covers located in front of the rear suspension subframe help improve airflow.

NOISE INSULATION

The TSX make use of extensive insulation features to reduce the interior sound level. Four separate strategies are employed:

A thorough insulation package including melt sheet is applied to lower unit body areas.
The floor carpet provides sound absorption and insulation to markedly reduce road noise in the passenger compartment. For 2011, interior floor mats are a more robust design with updated damping material.
Floating front and rear suspension subframes are rubber mounted to reduce road and suspension noise, vibration and harshness (NVH).
A, B and C-pillar separators are also used.

A-, B- & C-PILLAR SEPARATORS

In vehicles, generally the A-, B- and C-pillars that extend vertically from the floor of the vehicle to the roofline are hollow, which can transmit road and wind noise into the passenger compartment. The TSX pillars are sealed internally, dramatically reducing the transmission of noise and vibration.

WIND NOISE REDUCTION MEASURES

Acura has always put much emphasis on building an interior that is exceptionally quiet, and for 2011 the TSX cabin is even more serene thanks to items such as a new acoustic glass front windshield, even thicker side glass and increased use of sound-deadening insulation.

A comprehensive series of features dramatically reduces audible wind noise inside the TSX – especially at higher speeds or in windy conditions.

Wind noise reduction measures include:

Inside frame rail system positions structural frame rails above the floor rather than below it. This smoothes the bottom of the vehicle for reduced air turbulence.
A series of new underbody covers controls airflow underneath the car and around the front and rear tires.
A new design windshield that makes use of acoustic glass.
Windshield wipers and arms positioned below the hood line.
Rear doors feature thicker side window glass for 2011
Flush-mounted side window and moonroof moldings reduce air turbulence.
Exterior mirror housings are aerodynamically shaped to reduce turbulence.

ACOUSTIC WINDSHIELD

Special acoustic glass is now used on the 2011 TSX windshield to help reduce noise entering the cabin. Tuned specifically to attenuate wind-noise frequencies, the unique windshield uses two layers of 2 mm safety glass with an in-between layer of a transparent elastic acoustic membrane for a total thickness of 4.7 mm. The acoustic windshield (in conjunction with 4 mm thick side windows) helps position the TSX at the top of its class in wind-noise performance.

EXTERIOR GLASS

For 2011, the TSX now features thicker glass for the side windows. Now measuring 4.0 mm thick (previous thickness was 3.1 mm), the rear doors feature new glass that helps produce an even quieter cabin. All exterior window glass on the TSX, including the new acoustic glass front windshield, have a special UV-resistant coating that helps reduce interior temperatures, lessens glare, and helps protect the leather and other surfaces inside the vehicle from fading.

EXTERIOR LIGHTING

The 2011 TSX uses restyled projector-style Xenon High Intensity Discharge (HID) low beam headlights and 60-watt halogen high beams. In addition, the rear taillights incorporate a bright array of incandescent bulbs that illuminate in conjunction with a Center High Mounted Stop Light (CHMSL). Front bumper-integrated fog lamps are standard equipment on the TSX.

EXTERIOR COLORS

A range of seven exterior colors (including a choice of four pearl and three metallic colors) are designed to compliment the TSX sedan's sporty styling. Body colors are applied with a waterborne paint process to reduce environmental impact and waste.

	Basque Red Pearl	Crystal Black Pearl	Premium White Pearl	Vortex Blue Pearl	Graphite Luster Metallic	Forged Silver Metallic
Ebony interior		●	●	●	●	●
Taupe interior	●	●	●		●	●
Parchment interior	●	●	●

MOONROOF

The TSX features a power sliding moonroof that is flush mounted to reduce wind noise. A pop-up wind deflector reduces turbulence and noise when the moonroof is open. In addition, an inner panel further reduces noise from entering the passenger compartment when the moonroof is closed.

For ease of operation, a one-touch switch is mounted on the ceiling just ahead of the moonroof. The switch controls open/close as well as tilt functions. The moonroof also features an auto-reverse feature for safety and may be operated after the ignition is turned off (until the driver's door is opened).

POWER WINDOWS

The 2011 TSX is equipped with both driver- and front passenger-side power operated auto-function up/down windows. With a light touch of the window switch, the side windows will either lower all the way or rise all the way. An auto-reverse feature reduces the likelihood of injury in the event that a passenger's hand or arm is extended out the window while it is closing.

EXTERIOR MIRRORS

The TSX's passenger-side exterior rearview mirror features a power-activated Reverse gear tilt-down feature. When Reverse gear is engaged, the passenger side mirror automatically tilts downward to provide an improved view of curbs or painted lines. If desired, the tilt-down feature can be disabled. The exterior mirrors are also heated to improve rear visibility in foggy or icy conditions, and feature a special tint to reduce glare. The mirror housings are designed for good aerodynamics and incorporate turn indicators at the outer edges of the housings.

ELECTRIC FUEL-FILLER DOOR LOCK

The TSX's fuel-filler door locks and unlocks automatically along with the doors. By eliminating the need to reach for the traditional floor-mounted cable release, the system simplifies the process of refueling the car. As long as the driver's door is unlocked, opening the fuel-filler door is as simple as gently pushing on the rear edge of the door to release its latch. Latching the door requires a gentle push.

DOOR EDGE GARNISH

To provide a more finished interior appearance, an attractive metal garnish covers the inside edges of front and rear door ends except for the door latch (and the child safety locks on the rear doors). This improves the visual appeal of the doors when they are open.

TRUNK UTILITY

The TSX sedan features a wide and usable trunk that makes loading bulky or heavy items easy. Widely spaced trunk lid hinges provide greater clearance, and when closed, the hinges disappear into slots in the finished trunk lining that do not intrude on cargo space. Plus, the hidden hinge design improves trunk aesthetics and gives a more high-quality feel. The fully lined and illuminated trunk can accommodate a wide range of cargo, including four golf bags or four Pullman-style suitcases.

Trunk Opener

The TSX sedan's trunk latch may be released with the remote transmitter built into the folding ignition key, via a pushbutton on the trunk lid rear fascia (when the doors are unlocked) or by pushing a button located on the driver's inside door panel. An emergency cable release is available in case the TSX battery should ever run down.

2011 Acura TSX - Chassis

INTRODUCTION

In keeping with its lean, athletic appearance, the 2011 TSX offers a flat ride that is free from excessive pitching motions, along with outstanding agility and steering precision. Several chassis developments (such as a highly rigid body design with a cross-braced roof structure and a safety cage-type rear bulkhead structure) help contribute to the TSX's dynamic performance. With the all-new TSX Sport Sedan, a special rear hoop structure generates excellent body rigidity, and a light weight tailgate structure keeps body mass low.

SUSPENSION

The TSX suspension's high roll center (the geometric axis on which the body rolls or leans while cornering) reduces body lean during cornering, which better equalizes the workload for all four tires while also improving passenger comfort.

Front suspension
Double-wishbone front suspension components include stamped-steel upper A-arms, cast-iron steering knuckles, cast-iron lower A-arms, coil-over dampers and a large front stabilizer bar. A robust steel subframe cradles the engine, transmission and lower suspension components, and mounts on rubber bushings tuned to reduce road and engine noise, vibration and harshness (NVH) without compromising handling agility or steering precision.

For the TSX fitted with the 3.5L V-6 engine, the front suspension has been upgraded with unique front springs and revised dampers. The revised suspension accounts for the increased weight of the 3.5L V-6 engine and generates a level of sporty handling that buyers will expect from the powerful TSX V-6 model.

Along with unique tuning for the Electronic Power Steering (EPS) system, the TSX Sport Wagon also makes use of dual-mode dampers that are specifically calibrated for the vehicle. Combined, the result is a wagon that drives like a sport sedan.

Rear suspension
The multi-link rear suspension includes stamped-steel upper A-arms, cast aluminum knuckles, double lower tubular lateral links, tubular-steel toe-control links, coil-over dampers and a large stabilizer bar. This suspension system provides excellent handling, together with a flatter ride and exceptional control of noise, vibration and harshness (NVH).

DUAL-MODE DAMPERS

All TSX models feature dual-mode dampers. While most conventional dampers are tuned to provide a compromise between ride comfort and sporty handling at different speeds, the TSX's dual-mode dampers are uniquely engineered to provide ideal damping rates at both low and high speeds.

With a typical suspension, damping forces rise with the speed of damper compression, such as occurs when the vehicle encounters road irregularities at high speed. This can cause significant ride harshness and noise that reduces passenger comfort and enjoyment. However, the TSX's dual-mode dampers are tuned to provide the ideal damping rates for comfort and smoothness at low speeds of damper compression, while also limiting the maximum damping forces to reduce ride harshness at higher speeds of damper compression. In this way, the TSX provides a wider range of comfortable ride quality and exceptional road holding under a wide variety of driving speeds and conditions.

Deflector plate technology
Acura's dual-mode dampers automatically adjust compression damping characteristics to suit the vehicle speed, cornering forces and road surface. The dampers use a unique "deflector plate stack" that deflects when the compression forces reach a certain level, such as when encountering a large bump or dip in the pavement at high speeds. When these severe forces act on an ordinary damper, oil cannot move quickly enough through the damping orifices and the effective damping rate climbs— resulting in an excessive shock transmitted into the vehicle body.

With the TSX's dual-mode dampers, when severe conditions are encountered, the plate stack momentarily deflects, allowing oil to pass through at a much higher rate (in essence "capping" the damping rate at a preset level). Allowing an increased flow rate in extreme situations noticeably reduces the shock transmitted into the vehicle body for improved comfort. Deflection of the plate stack is carefully calibrated and controlled by spring pressure force on the plate stack. The simplicity of the dual-mode damper system also means that no electronics or movable valves are required.

ELECTRIC POWER STEERING (EPS)

The TSX uses Electric Power Steering (EPS) which regulates steering via a computer-actuated electric motor. With the computer-controlled system, advanced algorithms built into the operating software allow for continuous fine-tuning of the steering assist forces so that minimal force is required at low speeds— such as when parking or maneuvering. Conversely, progressively higher steering effort is generated at higher speeds (such as when driving on the freeway) to deliver a sport-minded driving experience.

The EPS system found in the TSX is an evolution of an earlier EPS system found on the Acura NSX supercar. Its key features and advantages include:

The EPS system reduces the steering effort at low speeds, improving agility and ease of effort when parking or maneuvering in tight areas
Rigidity of the steering mount is higher, which allows a more precise and "connected" feel during high-speed maneuvers (such as during lane changes or when on winding mountain roads)
The EPS steering assist incorporates computer algorithms based on vehicle speed rather than engine speed, allowing TSX engineers the flexibility of tailoring the steering feel to match actual driving conditions— especially high-speed driving. The EPS steering algorithms incorporate steering assist changes for every 0.6 mph.
The EPS system is different (and uniquely tuned) for each of the TSX models: 2.4L I-4 sedan, 3.5L V-6 sedan, and the new Sport Wagon.
EPS employs a sporty, 13.5:1 steering ratio which further improves performance driving agility
In its evolution from the original NSX system, the TSX's EPS system uses a significantly more powerful electric motor teamed with a far more sophisticated microprocessor
By eliminating the conventional power steering pump assembly, EPS uses less engine power which improves acceleration and fuel efficiency

4-WHEEL DISC BRAKES WITH ABS

The 2011 Acura TSX features 4-wheel disc brakes. The front rotors measure 11.8 inches in diameter and are made of cast-iron with integrated radial vents for excellent heat dissipation and wear properties. At 11.1 inches diameter, the solid-type rear rotors provide enhanced braking capability during repeated use. Floating-style single-piston cast-iron brake calipers are used front and rear. For the TSX V-6, special rear brake pads are used. In addition, the V-6 model makes use of a larger brake master cylinder, a revised pedal ratio and a unique brake booster to deliver a more performance minded braking feel.

A sophisticated 4-channel Anti-lock Braking System (ABS) is standard and works in concert with the vehicle's Traction Control System (TCS), Brake Assist, and Vehicle Stability Assist (VSA) systems for an outstanding array of electronic dynamic aids.

WHEELS AND TIRES

The 2011 TSX sedan and TSX Sport Wagon come standard with 17x7.5-inch five-spoke aluminum alloy wheels that feature a new machined surface for the spokes. Fitted to the wheels are Michelin Pilot HX MXM4 P225/50R17 93V all-season tires developed specifically for the vehicle. For TSX V-6 models, the wheels are upgraded to 18x8-inches in size and are fitted with performance minded Michelin Pilot HX MXM4 P235/45R18 94V tires. All TSX wheels have a clear-coat finish designed to provide good looks and added protection when the wheels are exposed to harsh weather conditions. Located under the trunk floor panel is a T135/80D16 temporary spare tire mounted on a 16x4-inch steel wheel.

TESTING

Dynamic testing and chassis tuning for the TSX was conducted both in Japan and America. The TSX was specifically tuned for the best combination of agility and handling needed in an urban environment and at higher speeds. The Los Angeles area (with its huge variety of road surfaces, freeways and varied topography) proved invaluable in chassis tuning to achieve a balanced overall package. Also invaluable was a "mini-Nürburgring" test course built in Japan that is designed to replicate some of the most demanding elements of the famed German racetrack.

2011 Acura TSX - Interior

INTRODUCTION

Step over the polished doorsill plates to enter the TSX interior, and the purposeful nature of the vehicle is immediately apparent. Blending luxury, performance and technology in equal measure, the TSX's interior exhibits a high level of fit and finish that customers have come to expect from Acura. And for 2011, the utility of the TSX increases dramatically with the availability of a new Sport Wagon model. With crisp styling and added utility, the TSX Sport Wagon is a smart alternative for those considering a compact SUV. The Sport Wagon offers a multi-configurable rear cargo area (with numerous hidden storage areas) and a low lift-over height allowing for easy loading, and an available power actuated tailgate.

Inside, the 2011 TSX receives a host of visual upgrades in the form of revised styling for the center console, darker trim pieces, brightly finished door handles, an updated parking brake handle, new steering wheel garnishes along with contrasting-color stitching for the leather seats, door armrests and center console. Rear seat occupants will enjoy added comfort thanks to the addition of heating/cooling vents mounted at the rear of the center console. Plus, the 2011 makes use of even more LED lighting now including the front footwells.

Acura is known for its outstanding array of user relevant technology, and the 2011 TSX further expands on this concept. New for 2011, the TSX with available Technology Package now includes a full VGA navigation screen (that generates 400-percent higher resolution than before), Song By Voice™ (SBV) user interface, a 60-gigabyte hard disk drive (HDD), and the ability to download 15-gigabytes of personal music to the HDD. With the ability to store more than 3,500 songs, there is longer any need to haul around a stash of bulky CDs.

The driver's cockpit is engineered for comfort and precise control, with many controls positioned within fingertip reach on the thick, leather-wrapped steering wheel. With the Sequential SportShift 5-speed automatic transmission, racing-inspired shift paddles mounted on the back side of the steering wheel make for convenient gear changes. Sport minded front bucket seats offer enhanced lateral support, and the driver's seat is 8-way power adjustable with lumbar support. The roomy 5-passenger interior offers standard leather seating surfaces, as well as standard dual-zone automatic climate control. Convenient standard 60-40 fold-down rear seatbacks reveal a pass-through to the trunk to expand cargo-carrying versatility.

Typical of Acura, the TSX offers an exceptional level of standard equipment. Included are standard power-actuated driver and front passenger seats, a folding key fob with remote entry, "quick vent" functionality and 2 personalized memory settings, automatic headlight activation, premium 7-speaker audio system with AM/FM tuner, CD, XM® Radio with Note function, USB port and AUX jack connectivity along with a Bluetooth® HandsFreeLink® cellular phone interface.

STYLING

The TSX's sport-oriented interior is designed to evoke a premium, avant-garde appearance with a blend of high-quality materials and graceful accents. Interior shapes are sweeping and fluid, and front and rear doors have sweeping armrests that are integrated with the door pulls. Satin metal finish accents arc across the instrument panel and along the sides of the center console, and vehicle entry is over metal sill plates bearing the Acura logo.

For the driver, large analog gauges are easily legible and the small-diameter steering wheel has a thick, leather-wrapped rim for a sporting feel. Controls for many fundamental systems are positioned on the steering wheel within fingertip reach, including racing-inspired steering wheel mounted paddle shifters for the 5-speed automatic transmission. A large digital display within the tachometer face shows gear selection when the transmission is in manual mode. The interior comes in three premium colors: Ebony, Parchment and Taupe.

DRIVER-ORIENTED COCKPIT

The TSX is designed to provide the driver with a functional and refined cockpit that puts controls within easy reach. The primary controls (the steering wheel, pedals, and console shifter) are positioned for comfort and control.

Sport-oriented seating offers added lateral support for spirited cornering. The 8-way power adjustable driver's seat is positioned low for improved headroom and a lower center of gravity. The seat includes a 2-position memory feature. The steering column tilts and telescopes to accommodate drivers of varying sizes.

Instrumentation and controls are clearly legible and switchgear offers precise tactile feedback. Automatic and manual transmissions are offered with the TSX 4 cylinder sedan, and both are designed for ease of operation. The 6-speed manual transmission has short throws like those of a sportscar. The Sequential SportShift 5-Speed automatic transmission has a simplified straight-style shift gate located on the center console along with racing-inspired paddle shifters that are within fingertip reach on the steering wheel.

Controls for the power moonroof (with tilt and auto-open/close) are located overhead in an intuitive location. The trunk can be opened via a button positioned within easy reach in the driver's door panel. The fuel filler door is electrically locked anytime the doors are locked, eliminating the need for a cable-style fuel door release button. When the power door locks are unlocked, the fuel filler door can be easily opened.

LEATHER-WRAPPED STEERING WHEEL

In keeping with its sporting mission, the TSX has a thick leather-wrapped 3-spoke steering wheel that integrates many control functions. Audio controls are positioned on the left spoke while cruise-control switches are on the right spoke. On cars equipped with the Technology Package, Acura Navigation System with Voice Recognition™ controls are located on the bottom spoke of the steering wheel. When equipped with the Sequential SportShift 5-speed automatic transmission, a pair of shift paddles are positioned behind the steering wheel.

LED Instrumentation WITH MULTI-INFORMATION DISPLAY

The TSX's analog instrumentation has satin metal-finish bezels and a clean, uncluttered look that makes it easy for the driver to interpret readings. LED backlighting makes the large gauges clear-- day or night. The illuminated pointers on the tachometer and speedometer are "floating," and appear to sweep around an invisible center pivot.

When equipped with the Sequential SportShift 5-speed automatic transmission, the tachometer face includes a digital gear selection indicator. The V-6 model receives an updated tachometer face with a unique rpm redline range that corresponds to the operating parameters of the 3.5L V-6 engine.

A Multi Information Display (MID) positioned in the speedometer face displays outside temperature, vehicle mileage and trip mileage, instant as well as average fuel efficiency readouts and Tire Pressure Monitoring System (TPMS) tire pressure status. Maintenance Minder™ also alerts the driver of upcoming maintenance needs via the MID.

To give the TSX a welcoming feel, when the door is first opened, the instrument lighting comes on at a low brightness; when the key is put in the ignition, the brightness progressively increases to 100-percent illumination. Then when the ignition is turned on, the illuminated instruments come to life, indicating that all systems are up and running. At the end of the drive, the illumination process reverses. New for 2011, crisp, bright LED lighting illuminates the front footwell when the doors are opened.

SEATING

During spirited acceleration, cornering and braking, secure seating for the driver and passengers is an important part of overall comfort. With high lateral loadings the driver's seat becomes an important part of the control system, helping the driver read the dynamic information the chassis and powertrain convey. Specific attention was given to increasing shoulder-area support for enhanced comfort while cornering.

With 8-way power adjustability, the TSX driver's seat provides an accommodating fit and two different seat position profiles can be stored in memory. Each seat profile is linked to one of the pair of folding ignition keys with integral remote-entry transmitter. When the driver uses the remote entry feature of the key, the TSX automatically adjusts the driver's seat to the preset position as well as links the driver-side exterior mirror and radio presets. The buttons used to preset the seating positions may also be used to select the individual seating positions if the seats have moved since unlocking the doors.

The driver's seat backrest lumbar mechanism is adjustable via a lever mounted on the right side of the seat back. The mechanism is designed to offer smoothly contoured support without the "sharp edged" feel of some less sophisticated mechanisms. TSX is equipped with a 4-way power adjustable front bucket seat for passenger comfort. To eliminate the chill on cold days, the TSX features heated front seats that can warm at two different levels.

INTERIOR ROOM

The TSX's wide wheel track and overall body width translate into a spacious interior cabin. The TSX's efficient packaging offers comfortable long-haul space for four passengers, and can accommodate up to five passengers for shorter drives. Rear seat room is particularly impressive relative to other vehicles within the TSX's class, with the TSX offering adequate leg and headroom for passengers over six feet tall.

CARGO CARRYING VERSATILITY

When more space is needed, the lockable 60/40 split fold-down rear seatback can be lowered by pulling release handles that are easily accessible from inside the trunk. Once released, the rear seat backs fold down to reveal a cargo pass-through to the back seat area. Trunk cargo volume of the TSX sedan is 12.6 cubic feet, with a total vehicle cargo volume of 107.1 cubic ft.

TSX Sport Wagon rear cargo area

The TSX Sport Sedan features an even greater level of utility than with the TSX sedan. Besides offering a generous 60.5 cu-ft of rear cargo area (with rear seats folded down), the wagon's rear opening height of approximately 28-inches allows for the stowage of bulky items such as large boxes, furniture, bicycles, four full-size golf bags and even surfboards. In addition, the Sport wagon features four hidden compartments for out-of-sight storage. A 2.4 cu-ft storage area is cleverly located beneath a lift-up hatch within the load floor. Smaller items can be placed in a 0.2 cu-ft storage area (hidden by a removable panel) located in the side panel on the driver side, or in one of two 13-inch long storage areas near the main in-floor storage area. With a low lift-over height of about 24-inches, loading heavy items is simplified. For increased security, standard is a retractable cover that prevents rear cargo items from being seen should a passer-by look into the rear windows.

With the second row seat in use, there is 25.8 cu-ft of cargo space available. The rear seats are a 60/40 fold-down design, so one section can be lowered to generate more cargo room while the other section can remain in the up position to accommodate a rear seat passenger. Or, fold down both seats to attain the maximum cargo area replete with a load-flat floor that is nearly 70-inches long. As expected, the TSX Sport Wagon incorporates a variety of tie-down hooks for keeping cargo items secure.

The TSX Sport Wagon's 60.5 cu-ft (rear seats folded down) of rear cargo area is more than any other wagon in the category-- including the BMW 3 Series (54.7 cu-ft) and the Audi A4 (56.5 cu-ft). Interestingly, the TSX Sport Wagon also rivals (or beats) the cargo capacity of many compact SUVs or CUVs. Thus, the Sport Wagon is a smart alternative for those who are considering the purchase of a small SUV-- but who value the better fuel economy, lower emissions and improved performance of a sport sedan.

COMFORT AND CONVENIENCE ITEMS

The TSX interior is designed to help make passengers comfortable along with offering plenty of customer-relevant features. Front and rear cupholders accommodate large drinks, convenient storage bins and compartments include seatback map pockets and bottle holders in all four doors, and the front door panels also have large map pockets. A 2-section locking glove compartment has a damped door, and there is also overhead sunglasses storage, while the center console incorporates side utility pockets. Beneath the sliding, padded armrest, the center console storage compartment has an internal 12-volt power point, a 2.5 mm auxiliary input mini-jack for the audio system, and a USB jack for the easy connection of a compatible audio device (such as an iPod®) to the TSX's audio system.

A versatile Multi-Information Display located in the speedometer face tracks the vehicle's maintenance needs, shows warnings and offers an array of driver preference settings. The TSX also features a dash mounted electronic compass for added directional information while driving. Illuminated door-mounted window switches are easy to locate at night. A HomeLink® remote system allows the control of up to three home electronic devices remotely from inside the car.

DUAL-ZONE AUTOMATIC CLIMATE CONTROL SYSTEM

The TSX has as standard a dual-zone automatic climate control with clear, intuitive controls. A replaceable filter system helps remove particulates from the interior air. When equipped with the Acura Navigation System with Voice Recognition™, key HVAC system functions can be accomplished via voice commands. In addition, the navigation system calculates sun position to adjust system operation from side to side to help compensate for solar heating.

INTERIOR COLOR & TRIM COMBINATIONS
Three interior colors are available, including Ebony (black), Taupe (gray) and Parchment (ivory). The upper instrument panel in all versions is black, while the lower instrument panel color matches the interior color.

REMOTE ENTRY

Two folding ignition keys with integrated remote transmitters are provided with the TSX. Each transmitter can be linked to one of two driver profiles. The key fob that is used to unlock the vehicle triggers a specific driver profile and the system automatically positions the power driver's seat, adjusts the side mirrors and sets the radio presets to match that profile.

Using the key fob, one push of the unlock button unlocks the driver's door while a second push unlocks all the doors. When placed in the driver's door lock, one twist unlocks only the driver's door while a second twist unlocks all the doors.

The TSX also features a unique "quick vent" feature that (when holding the unlock button on the keyless remote for two seconds) instantly lowers all four door windows and opens the power moonroof to quickly vent the built-up interior heat. In addition, by holding the key in the "lock" position, all open windows can be simultaneously raised.

BLUETOOTH® HANDSFREELINK® WIRELESS TELEPHONE INTERFACE

All Acura vehicles have as standard a Bluetooth® HandsFreeLink® telephone interface system that is designed to work with a wide variety of Bluetooth® enabled mobile telephones. Bluetooth® is a radio frequency-based technology that allows portable devices (such as cellular telephones, PDAs, laptops and other devices) to communicate wirelessly over a limited distance. The TSX's HandsFreeLink® system is compatible with Bluetooth®-enabled cellular phones that have the Hands Free Profile (HFP). (Some early Bluetooth®-enabled phones do not have this communications protocol, but most new phones have HFP.) After the driver completes a one-time pairing process, the TSX can communicate wirelessly with the driver's cell phone when it is within approximately 10 feet of the vehicle. The telephone needs to be on (with Bluetooth® connectivity enabled), but can be stowed in a pocket, briefcase, purse, or anywhere inside the TSX cabin.

With Bluetooth® HandsFreeLink®, the TSX driver can make or answer telephone calls without removing their hands from the steering wheel. When a call comes in, the incoming caller's telephone number is displayed on the Multi-Information Display (MID). In addition, a phone ring tone can be heard via 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 TSX's audio system speakers. On Technology Package models, a special overhead array microphone helps cancel "echo effect" and reduces background noise to improve the transmission quality of the driver's speech when using the HandsFreeLink® system.

By activating the Bluetooth® HandsFreeLink® system using fingertip controls mounted on the steering wheel, the driver can dial a telephone number by voice. The driver also can store frequently called numbers in the system's memory using unique voice tags. Up to six different compatible mobile telephones (each with a unique "user profile") can be paired at one time with the TSX's Bluetooth® HandsFreeLink® system.

Each phone profile has its own password-protected call history, phonebook, speed dials and voice tags. With a single paired phone and the proper password for each profile, a user can access any of the other profiles. This convenient feature means that a person who carries both a work cellular phone and personal cellular phone can easily access both profiles from either telephone.

When equipped with the available navigation system in the Technology Package some HandsFreeLink® functions are displayed on the high-resolution navigation system screen. This provides a versatile interface for HandsFreeLink® operation. The system can also import a compatible cellular telephone's phonebook (over 1,000 entries), allowing the data to be more easily searched via the new full VGA high-resolution color screen. Additional HandsFreeLink® information can be found at www.acura.com/handsfreelink.

PREMIUM 7-SPEAKER AUDIO SYSTEM WITH CD AND AM/FM/XM® TUNER

The TSX's Premium audio system delivers a high performance listening experience. Engineered for simple and intuitive operation, the audio system incorporates an AM/FM tuner, XM® Radio and a single-disc CD player. The system also displays Radio Data System (RDS) information, which appears as text showing station name and program type.

Multiple audio sources
The TSX's audio system can play program material from a wide variety of sources. The single-disc CD player can read discs encoded with MP3 or WMA® files, and there is a 2.5 mm auxiliary mini-jack in the center console for use with an external MP3 player. A USB port and cable is provided in the center console for the easy connection of an iPod® or compatible MP3 player. When used with compatible iPod® models, the USB connection also provides charging power and allows the display of iPod® content information on the audio system head unit. Control of the iPod® is via the audio head unit for maximum convenience.

The TSX has as standard equipment an XMÒ Radio receiver that (when activated) offers over 130 digital channels devoted to music, sports, talk, traffic, weather, children's programming and entertainment. Of the 130 XM® channels, 69 are commercial-free. A 90-day complimentary subscription to XMÒ is included.

The audio system also offers Bluetooth® Audio, a new technology for Acura. When the system has been paired with a compatible cellular telephone that incorporates a built-in audio player, the phone's audio content can be played on the TSX audio system via a wireless Bluetooth® connection. With the phone turned on and its music player running, the TSX audio system allows control of volume, forward and back track skipping along with pause/resume via the vehicle's audio head unit (function not legal in all states).

360 watts of power
The 360-watt audio system has a total of seven speakers. A pair of tweeters are positioned in the top of the instrument panel, and two 6.3-inch drivers are positioned in the front doors. The rear deck has another pair of 6.3-inch drivers, along with an 8-inch subwoofer (mounted on the right side of the cargo area in TSX Sport Wagon). An in-glass antenna (located in the rear window) is optimized to help deliver excellent radio reception without having a negative impact on vehicle aerodynamics. Remote controls located on the TSX's 3-spoke steering wheel put frequently used audio functions within fingertip reach of the driver.

ACURA/ELS SURROUND® PREMIUM AUDIO SYSTEM WITH 10-SPEAKERS, DVD-AUDIO, DTS™, CD PLAYER, AND AM/FM/XM® TUNER

When equipped with the available Technology Package, the TSX includes a spectacular Acura/ELS Surround® Premium Audio System featuring 10-speakers and DVD-Audio. 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. The sophisticated ELS® system, developed together with Panasonic Automotive Systems, uses 10 speakers and a total of 415 watts of power (460 watts with the Sport Wagon) to create a unique listening experience in the TSX.

Like the 7-speaker Premium audio system, the Acura/ELS Surround® Premium Audio system can play program material from a wide range of sources. The CD player can read discs encoded with MP3 or WMA® files. There's a 2.5 mm auxiliary mini-jack for use with an external MP3 player, and a USB jack and cable is located in the center console for the connection of an iPod® or compatible MP3 player. When used with compatible iPod® models, the USB connection provides iPod® control via the audio head unit. Bluetooth® Audio allows a compatible cellular telephone with a built-in audio player to wirelessly play the phone's audio content on the TSX audio system.

The Acura/ELS Surround® audio system features selectable Dolby® Pro Logic® II signal processing that creates simulated 5.1-channel surround sound from CD, MP3/WMA®, XM® Radio, AUX and USB inputs. The TSX audio system plays conventional CDs and DTS™ discs, in addition to DVD-Audio discs.

While Elliot Scheiner and Panasonic Automotive tuned the Acura/ELS Surround® Premium Audio system to create outstanding sound from any source, DVD-Audio is the system's most impressive sounding format. This advanced audio reproduction technology delivers over 500-times higher resolution than traditional CD audio. DVD-Audio delivers smoother, fuller and far more accurate sound through six discrete channels. (The system will not play DVD movies, DVD-V or DVD-R/RWs.)

To make Acura/ELS Surround® system simple to operate, it has large-format dash-mounted controls. In addition, steering wheel-mounted controls of key audio functions are positioned within fingertip reach. Select audio system functions can also be executed via voice commands.

Hard Disc Drive
The TSX has a new hard disk drive (HDD) media storage space with 15-gigabytes of storage capacity dedicated to music storage (the balance of the HDD's 60-gigabyte total storage capacity is used for the navigation system). The hard drive's fast file-access time speeds search and retrieval of audio tracks, and allows tracks to be shuffled by album, artist and genre.

On-board information provided by Gracenote® (formerly CDDB®) allows the audio system to display the song artist, album name, track name, and genre for the program material that is stored on the HDD. Gracenote® uses a multi-step recognition method to enable identification, categorization and organization of digital music. The Gracenote® database is updated quarterly to include new audio releases. The TSX owner can download Gracenote® updates at www.acura.com, and then load the updates onto a USB thumb drive or CD-R which, in turn, can be downloaded into the TSX's audio system. Without the Gracenote® update, new audio tracks will play on the Acura/ELS® system, but will play without accompanying text information on genre, artist, album name and track name.

The HDD media storage means that the TSX owner can download CDs directly to 15-GB (enough capacity to hold over 3,500 songs*) of dedicated hard drive storage for later playback. Once the CDs are downloaded to the HDD, the TSX owner no longer needs to carry around a bulky collection of CDs. Only original CDs and uncompressed CD-R files can be copied to the hard drive. Other formats such as DVD-Audio, MP3/WMA, DTS CD, USB, Bluetooth® audio and AUX inputs can not be recorded to the hard drive.

*Approximate capacity based on an average size of 4.0 MB per song at a 128kbps bitrate

10-speaker array
Each of the 10 speakers in the Acura/ELS Surround® Premium Audio system uses a high-energy Neodymium magnet for excellent sound quality and to reduce weight. There are soft-dome tweeters in the mirror patch location, plus a 2.75-inch midrange polypropylene-cone center speaker in the middle of the dashboard top. Each of the doors has 6.7-inch full-range dual-thickness polypropylene-cone speakers, and in the rear parcel shelf there are two more 6.7-inch drivers flanking a special Super Low Distortion 8-inch diameter subwoofer. The combination of high performance speaker drivers, optimal speaker locations and 415 watts of power (460 watts with the Sport Wagon) creates an audio system that delivers outstanding sound at any seating position.

An AM/FM tuner gets signals from a powered, active glass-mounted antenna that is laminated into the rear window glass. The system displays Radio Data System (RDS) information, which can show items such as station name and program type.

XM® Radio
The TSX audio system includes an XM® Radio receiver, which provides more than 130 channels of digital program material and near-CD quality sound. XM® Radio offers virtually uninterrupted coast-to-coast coverage within the 48 contiguous states and coverage to densely populated regions of Canada; service for Alaska and Hawaii is not available at this time. Three months of complimentary XM® service is provided, and when equipped with the Technology Package, the complimentary period also includes AcuraLink Real-Time Traffic™ and AcuraLink Real-Time Weather™. After the complimentary period, XM® Radio requires a monthly subscription.

XM® programming includes channels devoted to music, sports, talk, traffic, weather, children's programming and entertainment. Of the 130 XM® channels, 69 are commercial-free. When the TSX's audio system plays XM®, the display screen shows the current station, song title, or artist's name.

Note Function for XM®
The TSX audio system includes the Note function for XM® Radio which is designed to be a convenience for owners who want to make note of songs heard on XM®. With the touch of a button, the Note function for XM® Radio records the current song title and artist name in text form, along with a short audio excerpt of the song.

The Note function captures up to 10 seconds of each selected song and can store a total of 30 song excerpts for later playback. Thus, if the TSX driver likes a particular song or artist, it's easy to note (and refer back to it) for later consideration.

Song By Voice™
With so much audio content available with the TSX's new hard disk drive (HDD) media storage and in a user's iPod®, Acura engineers set out to make it easy to choose audio content while driving. Song By Voice™ (SBV) lets the driver choose music by artist, album, song title, genre, playlist and even composer.

From most navigation screens, the driver simply presses the "TALK" button on the steering wheel and then says "iPod Search" or "HDD Search." A category screen appears, and the user can choose by voice among categories to select the content they want. Alternately, selections can also be made using the interface dial. To improve voice recognition performance with unique words, the system has a feature that accommodates phonetic adjustment for up to 2,000 names. These updated phonetic names then apply to Song By Voice™ use of the hard drive or a connected iPod®.

ACTIVE SOUND CONTROL (TSX V-6)

The TSX V-6 receives an Active Sound Control system that is much advanced over Acura's previous Active Noise Cancellation™ (ANC) system. Whereas ANC dealt specifically with the elimination of low sound pressure entering the cabin, the new Active Sound Control system has a much broader range including the elimination of unwanted high frequency noise. In addition, Active Sound Control is linked to throttle position and engine rpm to provide a more quiet cockpit during normal cruising while allowing the 3.5L V-6's muscular sound to be heard more during higher rpm, higher speed driving.

Sporting a special array of processing technology and sensors, Active Sound Control not only improves sound cancellation but also works throughout the entire engine rpm range (whereas the previous ANC system only worked to cancel engine booming noise up to 2,000 rpm). Moreover, Active Sound Control is specially tuned for various levels of "effect" generated at different throttle positions: during low rpm, Active Sound Control delivers a quiet cabin; during mid-rpm throttle, some of the throaty exhaust note is allowed to enter the cabin; and during high rpm the Active Sound Control system is tuned to allow a more crisp exhaust note to enter the cabin.

Active Sound Control operates whenever the car is running, regardless of whether the audio system is on or off. There are two microphones mounted in the headliner-- one just behind the front overhead console and another just ahead of the overhead rear light module. The microphones capture low frequencies entering the cabin, and send a signal to the Active Sound Control unit. The Active Sound Control unit then creates a precisely timed reverse phase audio signal that is sent to an amplifier, which powers the door speakers.

The Active Sound Control dramatically reduces the booming noise of the exhaust, front and rear. In the frequency range below 100 hertz, Active Sound Control results in an impressive 10 dB reduction in noise level. Moreover, the Active Sound Control system helps reduce high frequency and middle-frequency noise attenuation during normal cruising.

Acura Navigation System WITH VOICE RECOGNITION™

Designed for easy, intuitive operation, the TSX's navigation system has a wide range of capabilities. The system features AcuraLink Real-Time Traffic™ along with AcuraLink Real-Time Weather™ that are useful tools that not only help the TSX driver navigate their drive route, but also provides important weather information along the drive route.

For 2011, the standard navigation screen is replaced with an 8-inch full VGA high-resolution color display with LED backlighting. The new screen generates substantially crisper graphics and more vivid colors. The full VGA monitor is positioned high up in the center of the instrument panel where it is close to the driver's line of sight while remaining shrouded from glare.

Also part of the system is a rearview camera (that projects an image on the VGA color screen) that helps provide added situational awareness for the driver when the vehicle is in Reverse.

System Operation

The Acura Navigation System with Voice Recognition™ tracks the TSX's position based on positioning data from up to 12 orbiting Global Positioning Satellites (GPS). If GPS reception is blocked by a tall building, tunnel, or parking garage, an internal gyroscopic system with a speed sensor tracks the location to keep the mapping information current and reliable until satellite reception is restored.

The TSX's navigation system stores its mapping data on a new internal hard disk drive (HDD). The same drive is partitioned and used by the audio system to store audio files. Much faster than the DVD drive used on the 2010 model, the new HDD is the key to the system's impressive search and routing speed. The system can be updated annually with the latest mapping information by inserting an update disc into the audio system's slot-loading CD/DVD drive. DVD update discs are available for purchase on an annual basis on-line at www.acura.com or by calling 888-549-3798.

The navigation system can be controlled by using the interface dial by choosing menu options or by spelling out a word (e.g., an address, business name or place). Characters on an on-screen keypad can be selected using the Interface Dial. For voice operation, the driver simply presses the "Talk" button on the steering wheel and says any of a number of preset command phrases. The system responds to over 700 command phrases, as well as to spoken city and street names. Voice recognition capability saves time and simplifies operation of the system.

The audio system is automatically muted when the "Talk" button is pressed, and an overhead array microphone receives the command from the driver. Commands can be given in plain English, like "Display gas stations," "Find nearest hospital," or "Find nearest Chinese restaurant." The TSX's voice recognition technology allows the driver to simply speak city and street names aloud, and the system responds by displaying matches available in the database. Points of interest on the map (such as restaurants or grocery stores) can be displayed or you can have the system provide turn-by-turn navigation-- all by voice command. The massive point-of-interest (POI) database includes telephone numbers, which can be dialed by using the Bluetooth® HandsFreeLink® system or with the driver's cellular telephone.

INTERFACE DIAL

Most frequently used electronic functions in the TSX have dedicated controls placed on the instrument panel or on the steering wheel. Voice control of navigation, climate control, audio and communications functions are available, while the interface dial positioned just ahead of the center console-mounted shift lever provides another avenue of control. The Interface Dial can be rotated and rocked like a joystick to select function menus displayed on the navigation screen. A push of the controller selects the highlighted item. Functions controlled by the Interface Dial include:

Audio system
Navigation system
AcuraLink® Satellite Communication System

Wallpaper image display
To further customize the TSX's interior, the navigation system allows the storage of up to 10 images each for each driver (two drivers total) on the built-in hard disk drive (HDD). Any one of the stored images can be displayed as a full-screen image on the navigation display when the display is not otherwise in use. To avoid driver distraction, there is no "slide show" function. J-peg images can be loaded from a computer onto a USB storage device, such as a thumb drive. Then the thumb drive can be plugged into the TSX's USB port that is located in the center console. Using on-screen menus, the images can then be transferred to the TSX's internal HDD. Each driver can then choose among their stored images for display, or set the system to not display wallpaper.

AcuraLink® Satellite Communication System

The TSX's available Technology Package includes the AcuraLink® Satellite Communication System (within the 48 contiguous United States). AcuraLink® allows two-way communication between Acura and the TSX, providing customers with the latest information specific to their vehicle.

Once the owner has enabled its data-transmission function, the owner's Bluetooth® telephone is used in cases where communication from the car to the Acura Telematics server is needed. In addition, while driving, the AcuraLink® system conveniently allows the TSX owner to make automated appointments for vehicle service. The data connection from the server to the vehicle is enabled even if the monthly XM® service package is not in effect.

Each AcuraLink® message is prioritized by importance, with high priority messages displayed immediately while normal messages trigger a message icon on the navigation display. To avoid distraction, low priority messages show up only on vehicle start-up. The owner can choose to read or listen to a message immediately, or archive it to be retrieved at a later time. AcuraLink® messages consist of a limited amount of text plus expanded details via Text-To-Speech.

Messages that can be sent to the TSX include Maintenance Minder™ (information regarding the next required maintenance), Quick Tips (information regarding the TSX features), Feature Guide (supplements to the TSX Owner's Manual) and Diagnostic Info (detailed information and instructions should an onboard system issue arise). The TSX owner has complete control over the types of messages they receive. All AcuraLink® preferences can be set via the MyAcura website (www.myacura.com).

AcuraLink® can provide the owner with important information that previously has been unavailable. For example, if a warning light should appear on the TSX instrument panel, AcuraLink® can automatically send a trouble code along with the sensor data associated with the fault to the Acura Telematics Server. The code is analyzed, and a message is sent back to the TSX-- such as "A software issue has been detected. It is OK to continue driving. The repair is currently being developed, so you do not need to visit your dealer at this time." A separate AcuraLink® message will be sent to the TSX when it is time to visit the dealer to have the system repaired. AcuraLink® can tell the TSX owner if a particular fault is serious enough to cancel a trip, if it can be dealt with later or if it requires special driving techniques.

ACURALINK REAL-TIME TRAFFIC™

With AcuraLink Real-Time Traffic™, the TSX's navigation screen can display regularly updated traffic information including traffic flow, incidents and construction on freeways in 109 major metropolitan areas within the United States and three major metropolitan markets within Canada. The information is part of the XM NavTraffic® feature (aggregated by NAVTEQ™ from multiple sources including police and highway patrol incident reports and transportation departments). Information is transmitted by XM® satellites to the TSX where it is graphically displayed on the navigation system-- with a zoom scale ranging between 1/20-mile to 5-mile increments.

To see details or select traffic incidents, the TSX owner can click on an icon on the map by pushing "Enter" on the interface dial. TSX drivers can avoid congestion en route and choose the fastest path to their destination with traffic information that is continuously updated. The system displays traffic incidents, determines average traffic speed and (if a destination is programmed into the navigation system) estimates travel time along the chosen route. It can automatically recalculate results as factors change. Plus, XM NavTraffic® alerts drivers of scheduled traffic incidents such as construction and road closures, plus unscheduled incidents such as incidents and disabled vehicles.

Traffic Rerouting™ 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.

AcuraLink Real-Time Traffic™ with Traffic Rerouting™ gives TSX owners a useful time saving tool on freeways. AcuraLink Real-Time Traffic™ is offered on a subscription basis following a 3-month free trial period. In addition to the on-screen traffic information, TSX owners who maintain their XM® Radio service also receive more general audio traffic information for 109 major metropolitan areas that runs on a 2-3 minute loop.

2011 Acura TSX - Safety

Introduction

The 2011 Acura TSX provides an extremely high level of standard safety equipment. Key safety technologies include the Advanced Compatibility Engineering™ (ACE™) body structure, a total of six airbags and the use of active front head restraints on the front seats. In addition, due to its heavier weight (versus the four-cylinder model), the TSX V-6 features a special polypropylene foam box added to the front bumper beam to provide enhanced energy absorption during a frontal impact.

Acura's "Safety Through Innovation" initiative is based on the brand's commitment to leadership in safety, and excellent safety is a paramount element in every new car Acura builds. The initiative's goal is for all Acura models to provide a high level of occupant protection along with injury mitigation to pedestrians, as well as increased crash compatibility with other vehicles, regardless of size or price.

Advanced safety technology
Advanced Compatibility Engineering™ (ACE™) Body Structure enhances occupant protection and crash compatibility in frontal crashes. The ACE™ design utilizes a network of connected structural elements to distribute crash energy more evenly throughout the front of the vehicle. 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.

Inside, the TSX incorporates dual-chamber front-seat side airbags with front passenger-side Occupant Position Detection System (OPDS) and active head restraints for the front seats that are designed to reduce the likelihood of neck injury in the event of a rear collision. These features compliment a 4-channel Anti-lock Brake System (ABS) with Brake Assist, front seatbelts with automatic tensioning system and load limiters, dual-stage/multiple-threshold front airbags, side curtain airbags for all outboard seating positions and an advanced pedestrian injury mitigation design for the hood, hood hinges and windshield wiper mounts. Daytime running lights (DRL) and driver and front passenger seatbelt reminders are also standard.

Standard safety features include:

Active Safety Systems

4-wheel disc Anti-lock Brake System (ABS) with Electronic Brake Distribution (EBD) and Brake Assist
Vehicle Stability Assist™ (VSA®) with traction control (electronic stability control)
Tire Pressure Monitoring System (TPMS)

Passive Safety Systems

ACE™ body structure
3-point seatbelts for all seating positions
Front seatbelts with automatic tensioning system and load limiters
Dual-stage, multiple-threshold front airbags
Dual-chamber front seat side airbags
Side curtain airbags for all outboard seating positions
Front seats with active head restraints
Head restraints for all outboard seating positions
Lower Anchors and Tethers for CHildren (LATCH) child car-seat attachment system located in the rear seat outer positions

ADVANCED COMPATIBILITY ENGINEERING™ BODY STRUCTURE

Like every other Acura vehicle, the 2011 TSX features Advanced Compatibility Engineering™ (ACE™) unit-body design. ACE™ is an exclusive body design that enhances occupant protection and crash compatibility in frontal crashes. The ACE™ design utilizes a network of connected structural elements to distribute crash energy more evenly throughout the front of the vehicle. 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.

If the TSX should collide head-on with a vehicle of different size, the Advanced Compatibility Engineering™ structure helps provide good engagement with the other vehicle's frame thanks to a special lower member that extends below the front bumper beam. This lower member helps ensure that if the TSX collides with a vehicle of differing size, the lower front member will better engage the other vehicle's bumper system. This helps reduce the risk of intrusion while simultaneously helping to disperse the crash energy across a wider area at the front of the vehicle.

Inside frame rails
Longitudinal frame rails are positioned above the floor panel rather than below it, both for aerodynamic improvements and to better withstand severe side impacts.

STANDARD VEHICLE STABILITY ASSIST™ (VSA®)

Standard equipment on all models of the TSX is Vehicle Stability Assist™ (VSA®)-- an Electronic Stability Control system that enhances controllability while the vehicle is accelerating, braking, cornering, or when the driver makes a sudden maneuver. The VSA® works in conjunction with the vehicle's Drive-by-Wire™ throttle system and its 4-channel anti-lock braking system (ABS) to help the vehicle maintain the driver's intended path of travel. VSA® functions by applying brake force to one or more wheels independently while also managing the throttle, ignition and fuel systems to reduce engine power output.

Vehicle Stability Assist™ constantly analyzes data from seven sensors that monitor wheel and vehicle speed, steering input, lateral G-forces and yaw rate-- then compares the driver's control inputs with the vehicle's actual response. Whenever the vehicle's actual response falls outside of a predetermined acceptable range, VSA® intervenes with corrective action. If VSA® detects an oversteer condition, the system may apply braking force to the outside front and rear wheels to counteract the unintended yawing effect. Or in the event of understeer, VSA® may apply braking to the inside rear wheel while reducing engine power to help return the car to its intended course.

Vehicle Stability Assist™ is calibrated to work in a nearly transparent manner, meaning that drivers may not even be aware of its operation. Therefore, to keep the driver informed, an indicator light flashes on the instrument panel anytime the system is enhancing vehicle stability. While the driver may deactivate the VSA® and traction-control functions via a switch on the instrument panel, ABS and Brake Assist remain fully operational at all times.

ADVANCED 4-CHANNEL ABS WITH ELECTRONIC BRAKE DISTRIBUTION

The 2011 TSX is equipped with 4-wheel disc brakes and a sophisticated 4-channel / 4-sensor anti-lock braking system. The system helps improve active safety by offering a firm brake-pedal feel and a short activation stroke, as well as Electronic Brake Distribution (EBD) circuitry that automatically proportions braking force between the front and rear wheels based on the vehicle's weight distribution. EBD helps maximize braking effectiveness whether the TSX is transporting only the driver, or is fully loaded with passengers and luggage.

BRAKE ASSIST

Brake Assist (which utilizes some of the VSA® system components) recognizes emergency braking situations and assists the driver apply maximum braking force to slow the vehicle more quickly. This important system is controlled by special computer logic that determines when the speed and stroke of the brake pedal exceed a typical range-- as they would in a panic stop. At this point the modulator pump increases braking pressure to ensure maximum stopping force and help shorten braking distance. Brake Assist functions only when the driver is pressing the brake pedal, and the additional braking force provided by the system ceases when the driver releases pressure on the brake pedal.

DUAL-STAGE, MULTIPLE-THRESHOLD FRONT AIRBAGS

Both the TSX driver and front passenger are protected by advanced front airbags that incorporate dual-stage and multiple-threshold activation technology. In the event of an airbag deployment, these two features work together to help minimize the likelihood of injuries that could sometimes be caused by the airbags themselves. In doing so, Acura's sophisticated dual-stage, multiple-threshold system matches the airbag deployment rate to both the speed and severity of a crash. The control logic also takes several other factors into consideration, including the seating position of the driver, the weight of the front passenger, as well as whether the seat belts are in use.

Dual-Stage, Multiple-Threshold Airbag Parameters

Airbag deployment thresholds are controlled depending on the severity of a collision, driver seat position, passenger weight, and the seatbelt buckle status of both occupants.
The dual-stage, multiple-threshold strategy applies to front airbags only and does not affect operation of side airbags or side curtain airbags.

For instance, during a lower-speed collision or if the seat is too close to the steering wheel, the inflators in the driver's frontal airbag will activate sequentially (instead of simultaneously) to help reduce the initial deployment force. In a high-speed collision or if the seat is positioned farther back, both airbag igniters are triggered simultaneously for rapid inflation. The TSX's passenger-side frontal airbag is designed to operate in a similar manner, however a sensor under the passenger seat calculates whether the weight on the lower cushion meets a minimum value specified by NHTSA. If it doesn't, such as in the event a child is occupying the seat, the airbag is deactivated – and a light on the instrument panel indicates such a condition.

The driver's front airbag is located in the steering wheel while the front passenger airbag is located on the top of the dashboard. When deployed, the passenger airbag inflates upward and then rearward to maximize its protective potential while reducing the likelihood of injuries being caused by the activation process.

DUAL-CHAMBER FRONT-SEAT SIDE AIRBAGS

The TSX has front-seat side airbags featuring a dual-chamber design that enhances protection for the torso and pelvis in the event of a severe side impact. Replacing the previous single-chamber airbags, the dual-chamber units have a larger upper chamber that provides improved protection for the chest area, as well as a smaller lower chamber that protects the lower-back/hip area. A single inflator unit fills both airbag chambers. Dual-chamber airbags are significantly more effective in helping minimize potential injuries caused by impacts from larger vehicles, such as a side impact involving a truck.

SIDE-CURTAIN AIRBAGS

Full side-curtain airbags provide head protection for occupants of both the front and outboard rear seats. The airbag modules are mounted in the roof and are activated by a central sensor and sensors in the side of the TSX that (depending on crash severity) determine the most appropriate timing and deployment rates in side or other impacts depending on severity.

FRONT SEATBELTS WITH AN AUTOMATIC TENSIONING SYSTEM

Front seatbelts
The TSX front seatbelts are equipped with an automatic tensioning system and load limiters to help minimize injury potential in a frontal collision. If an impact occurs, the automatic tensioning system automatically tightens the front seatbelt to help hold the occupant firmly in position. Each front seatbelt retractor also incorporates a load limiter that works in conjunction with the automatic tensioning system. The load limiter permits a small amount of controlled seatbelt slack momentarily after the automatic tensioning system is activated to limit peak restraining forces, helping to reduce the potential of serious bodily injury. The TSX's front seatbelts also feature adjustable height shoulder anchors.

Rear seatbelts
Three-point seatbelts are standard for all three rear-seating positions.

HEAD RESTRAINTS

Active front head restraints
The TSX front seats are fitted with active front head restraints designed to help minimize the risk of neck injuries in the event of a rear impact. The head restraint system is mechanically linked to a lumbar plate located inside the front seatback. In a rear impact, the occupant's body pushes against the seatback, causing the head restraint to move forward and upwards in a carefully prescribed arc. This motion helps equalize the impact forces transmitted to the neck and spine during the collision. Effectively managing and dispersing this crash energy is critical to help minimize the potential for injuries.

Adjustable rear head restraints
The TSX's rear seat features individually adjustable head restraints for all three passengers.

LOWER ANCHORS AND TETHERS FOR CHILDREN (LATCH)

The 2011 TSX includes a LATCH (Lower Anchors and Tethers for CHildren) child-seat mounting system for the outboard rear seating positions. LATCH features built-in lower anchors and ready-to-use tether attachment points that allow compatible child safety seats to be installed without using the vehicle's seat belt system. Additionally, the LATCH system simplifies child-seat installation when an owner installs a LATCH-compatible child seat. The rear seat center passenger position has upper tether anchors only.

TIRE PRESSURE MONITORING SYSTEM (TPMS)

An integrated Tire Pressure Monitoring System (TPMS) alerts the TSX driver whenever the air pressure in one or more of the vehicle's tires decrease significantly below the recommended pressure level. Using four sensors (one in each tire), TPMS monitors and transmits information regarding tire air pressure to the TSX's MID system. When the pressure in one or more tires drops to a significantly low level, it causes a low tire pressure indicator in the instrument cluster to illuminate.

PEDESTRIAN INJURY MITIGATION

The Acura TSX makes pedestrian injury mitigation a high priority, and adopts several pedestrian-injury mitigation measures that United States law does not require. These features include a deformable hood panel (positioned high enough above the engine and other under-hood components to have space to deform) as well as deformable hood hinges and movable windshield-wiper pivots. These components help dissipate collision forces in the event of contact with a pedestrian, thereby helping to reduce the likelihood, and potential severity, of pedestrian injuries caused by the vehicle-pedestrian contact.

Anti-Theft Features

The TSX offers a wide array of security features including an electronic engine immobilizer to help thwart would-be thieves. Security is also advanced by the use of reinforced door lock cylinders to help deter break-ins along with protectors for the hood and trunk locks.
