2021 Acura TLX Press Kit


The all-new 2021 TLX is the first Acura sedan created from the ground up based on Acura's Precision Crafted Performance brand direction. It continues the performance focus of Acura established with the launch of the second-generation NSX supercar, the brand's return to motorsports competition, and by new approaches to Acura design and technology first seen in the Acura Precision Concept and Precision Cockpit and later evolved in the Acura Type S Concept and in the newest-generation Acura RDX.

The 2021 Acura TLX takes a dramatic step forward as the most performance-focused sedan Acura has ever offered, built on an all-new platform, developed exclusively for TLX, and geared to the desires of today's sport sedan enthusiast.

This new generation of TLX also marks the return of Acura's celebrated Type S performance line after more than a decade-long hiatus. The new TLX Type S will supplant previous models as the most potent Type S model ever, deriving power from an all-new 3.0-liter DOHC turbocharged
V-6 engine developed exclusively for Acura and Type S. Moreover, the new TLX Type S will be the first Type S to utilize Super Handling All-Wheel Drive™ (SH-AWD®), now in its fourth-generation of advancement.

The TLX sport sedan and its predecessor, the TL sedan, are historically Acura's top-selling sedan models, with cumulative U.S. sales of more than 1.1 million units since the launch of the first-generation TL in 1995. Since the launch of the second-generation model, in 1998 (1999 model year), all TL and TLX models have been designed, developed and manufactured in the U.S. using domestic and globally sourced parts.

The new TLX launches on the heels of a successful new RDX sport-utility and integrates a number of the next-generation Acura technologies and features first deployed on RDX, including its 2.0-liter turbo engine, 4th-generation SH-AWD®, ELS Studio 3D® Premium Audio, 16-way sports seats, and the latest iteration of Acura's innovative True TouchPad Interface™.

The 2021 Acura TLX launches with four distinct grades: TLX, TLX with Technology Package, TLX A-Spec, and TLX with Advance Package. Eight exterior colors grace the exterior, including five premium colors: Phantom Violet Pearl (new), Majestic Black Pearl, Performance Red Pearl, Platinum White Pearl and Apex Blue Pearl. Interior color schemes, depending on grade and exterior color, include Ebony, Expresso, Parchment, Graystone and, for A-Spec, Ebony or Red with Black Ultrasuede® inserts.
Design and Packaging
The TLX's bold yet clean exterior form draws heavily upon the Acura Precision Concept with its near-exotic stance and proportion, sheer body surfacing and dramatic character lines. The TLX's more distinctive and premium presence is founded in its reconstituted exterior dimensions – a 3.7-inch longer wheelbase, 2.2-inch wider body, 0.5-inch lower height, and 7.8-inch longer dash-to-axle dimension. The resulting effect is stance and proportion unlike anything in its segment. Moreover, the TLX's long wheelbase, wider tracks (+1.2 in. front and +1.6 in. rear) and wider wheels and tires (+0.5 to 1.0 in.) contribute to the TLX's more athletic driving dynamics and refined ride quality.
The TLX's new look is highlighted by signature Acura design cues first seen on the Acura Type S Concept, starting with an all-LED lighting package that includes next-generation 4-lamp Acura JewelEye™ headlights, “Chicane” daytime running lights and taillights inspired by the ARX-05 DPi race car, along with a new, wider Diamond Pentagon grille, upswept rear deck, and large dual exhausts finishers.

Exclusive New Body and Chassis
The 2021 TLX is built on an all-new, Acura-exclusive body and chassis architecture designed for Type S levels of driving performance and shared across the full TLX lineup. The new Acura sedan platform heralds the return of the double wishbone front suspension as a foundational component of the TLX's handling prowess.  

In addition to the double wishbone front suspension, the TLX chassis employs a multitude of performance-focused technology and engineering upgrades. These include a new high-capacity, belt-driven and variable-ratio electric power steering system, NSX-derived electro-servo brake-by-wire technology, and available Adaptive Damper System, which provides for more responsive and also customizable ride and handling performance.

The TLX's new chassis is anchored to an advanced new body structure — the most rigid ever offered on an Acura sedan — delivering major gains in rigidity, including a 50 percent increase in global torsional stiffness and up to a 100 percent improvement in localized rigidity, where the suspension is mounted to the body. The new structure uses 64 percent (by weight) advanced, lightweight materials, such as aluminum and press-hardened steel, more than any previous Acura sedan.

An ultra-rigid new center tunnel serves as the backbone of the TLX's higher structural rigidity and is complimented by triangulated front strut tower bars, front and rear underfloor braces,  and Acura-first cast-aluminum front shock tower mounts. Front-to-rear weight balance is also improved by the extensive use of aluminum, including in the front bumper, hood, front fenders and front shock tower mounts, along with the relocation of the 12-volt battery from the engine bay to the trunk.

Advanced Powertrains
The 2021 TLX's new standard powertrain is the same 2.0-liter DOHC, direct injected and turbocharged engine and 10-speed automatic transmission that debuted in the latest-generation RDX sport-utility vehicle. The 2.0-liter turbo, with peak output of 272 horsepower and 280 lb.-ft. of torque, boasts the highest standard horsepower in the TLX's core competitive set and delivers major gains in torque when compared to the previous model's normally aspirated 3.5-liter V6 (+13 lb.-ft. at peak, +48 from low rpms) and its normally aspirated 2.4-liter 4-cylinder (+98 lb.-ft. at peak, +123 from low rpms). 

Acura's 10-speed automatic (10AT) offers a wider ratio range, more discrete gears, 4-gear direct downshifts, and a lower first gear for exceptional launch performance when compared to the previous 9AT, making exceptional use of the new turbo engine's high torque output.

Acura SH-AWD®
All grades of TLX can be equipped with the latest generation of Acura Super Handling All-Wheel Drive™ (SH-AWD®), with performance-elevating torque-vectoring capability.

Acura's 4th-generation SH-AWD® system has 40 percent more rear torque capacity and 30 percent quicker front-to-rear torque transfer than the 3rd-generation system in the previous TLX. The system can transfer up to 70 percent of engine torque to the rear axle, continuously apportioning 100 percent of that rear-axle torque between the left and right rear wheels. Additionally, the rear axle is continuously overdriven by 2.9 percent, which amplifies the yaw moment effect of left-to-right torque transfer, elevating performance through sharper and more accurate turn-in, enhanced and improved traceability when cornering.   

Sport Sedan Cockpit
Inside, the 2021 TLX's more premium, personal and technologically sophisticated cabin is designed around the needs and desires of today's luxury sport sedan enthusiasts, offering first-class seating comfort for the driver and front passenger, with exceptional hip, elbow and shoulder room courtesy of its wider body design. Overall passenger volume is slightly increased (+0.1 cu.-ft.).

In keeping with Acura's commitment to both performance and premium quality, the TLX cockpit eschews old-world opulence for a sharp and modern “cockpit” design with the tasteful integration of authentic, high-grade materials, including aluminum, open-pore wood, and full-grain, top-stitched Milano leather. For a more personalized cabin environment, the TLX with Technology Package features the new IconicDrive™ interior LED ambient lighting system with 27 selectable color themes. Three of those themes are tied to the Integrated Dynamics System, one each for Comfort, Normal and Sport modes, with an additional 24 themes named after iconic destinations and driving circuits.  

The 2021 TLX utilizes the full array of Acura's newest and most advanced comfort, convenience and connectivity technologies, including the innovative and driver-oriented Acura True Touchpad Interface™ featuring a high-mounted 10.2-inch HD display and “absolute positioning” touchpad; a full-color 7-inch Multi-Information Display (MID) in the center gauge cluster, and an available 10.5-inch Head-Up Display (HUD); along with an available 17-speaker, 710-watt ELS Studio 3D® Premium Audio system, and available 16-way power adjustable heated and ventilated Acura sport seats for both the driver and front-seat passenger (12-way seats standard for both front-seat occupants).

The new TLX's True Touchpad Interface integrates the latest OS updates with improved touchpad performance by implementing more accurate swipe zones and handwriting recognition, as well as other performance and cybersecurity enhancements. The TLX's True Touchpad Interface adds a more ergonomically optimized palm rest. Also, new console-mounted Power, Volume and Seek controls, next to the touchpad improve usability. The 2021 TLX features AcuraLink™ cloud-based services, including in-vehicle 4GLTE Wi-Fi, vehicle location, geofencing, and Acura concierge services.

Integrated Dynamics System with New Individual Mode
The new TLX offers a more personalized driving and cabin experience with its new Integrated Dynamics System, incorporating a multitude of powertrain, chassis and other systems, all tied into the center console-mounted, NSX-inspired Drive Mode Dial.

The new Integrated Dynamics System features Comfort, Normal and Sport modes, that integrate the Drive-By-Wire™ throttle, transmission, SH-AWD, steering, Adaptive Dampers (with Advance Package), along with Active Sound Control, idle stop functionality and ambient cabin lighting. Additionally, the new Individual mode allows the driver to choose their own ideal settings for each of these systems to create a fully personalized driving experience. Once programmed, Individual mode is activated very simply, in one step, by pressing the Acura symbol at the center of the drive mode dial.

Advanced Safety and Driver-Technologies
As an integral part of Acura Precision Crafted Performance, the new TLX is designed to provide advanced levels of both passive and active safety, utilizing the latest generation of Acura's proprietary Advanced Compatibility Engineering™ (ACE™) body structure and a full suite of AcuraWatch® safety and driver-assistive technologies, along with the first-ever application of the next-generation front passenger airbag technology, designed to protect occupants in a broader range of frontal collisions, including oblique-angle impacts.

The new TLX targets the highest available third-party safety ratings, a 5-Star Overall Vehicle Score from the National Highway Traffic Safety Administration (NHSTA), and a TOP SAFETY PICK+ rating from the Insurance Institute for Highway Safety (IIHS), including a GOOD rating in all collision tests and a SUPERIOR rating for frontal crash prevention, both vehicle-to-vehicle and vehicle-to-pedestrian.

All new TLX models come equipped with AcuraWatch® technology, incorporating new features, including Traffic Sign Recognition, Driver Attention Monitor, and new Traffic Jam Assist (enables Lane Keeping capability at speeds below 45mph). In addition, AcuraWatch features include Collision Mitigation Brake System™ (CMBS™) with pedestrian sensing and Forward Collision Warning (FCW), Lane Keeping Assist (LKAS) with Lane Depart Warning (LDW), Road Departure Mitigation, and Adaptive Cruise Control (ACC) with Low-Speed Follow. 

Additional standard driver-assistive features include a new Driver Attention Monitor, Multi-Angle Rear View Camera with dynamic guidelines, Vehicle Stability Assist (VSA) with Traction Control, and in-wheel tire pressure monitoring system (TPMS); while upper grades add features including Blind Spot Information (BSI), Rear Cross Traffic Monitor, front and rear parking sensors, Surround View Camera System, and automatic high-beam headlights.

Design, Development and Manufacturing
Like all TLX and TL models since the 1999 Acura TL, the 2021 Acura TLX was designed, developed and manufactured in the U.S. Styling design was led by Acura Design in Torrance, California, while development was led by engineers in the company's Raymond, Ohio R&D center. Engineering development of new 3.0-liter turbocharged V6 engine was led by the company's Tochigi, Japan, R&D center and supported by powertrain experts in Ohio.

The new TLX will be manufactured at the company's Marysville, Ohio, plant using domestic and globally sourced components. The TLX's 2.0-liter and 3.0-liter turbocharged engines will be produced at the company's Anna, Ohio, engine plant, also home to the NSX twin-turbocharged V6. Its 10-speed transmission will be manufactured in the company's Tallapoosa, Georgia, plant. The rear differential and the torque-transfer unit for the SH-AWD® system are manufactured in the company's Russels Point, Ohio manufacturing plant.

The 2021 TLX features a new generation of engine, transmission and driveline technology, with substantially increased performance across the full model range. The TLX's new 272-horsepower 2.0-liter turbocharged in-line 4-cylinder engine is the most powerful standard engine in the model's core competitive set.

The new turbo 4-cylinder engine offers substantially higher torque when compared to the previous model's normally aspirated 2.4-liter 4-cylinder (+98 lb.-ft. at peak, +123 lb.-ft. from low rpms) and its optional 3.5-liter V6 (+13 lb.-ft. at peak, +48 lb.-ft. from low rpms).

Both 2021 TLX engines are mated to an incredibly responsive and quick-shifting Acura-engineered 10-speed automatic transmission with a wider ratio range and more discrete ratios than the previous 9-speed automatic (TLX V6) and 8-speed Dual-Clutch Transmission (TLX 2.4L).

The TLX with the new 2.0-liter turbo is available with front wheel drive or with the latest generation of Acura Super-Handling All Wheel Drive™ (SH-AWD®)—using a fourth-generation rear differential with faster response and greater torque capacity.

Powertrain Architecture and Features

Cylinder Block and Crankshaft
The TLX's turbocharged inline 4-cylinder engine uses a lightweight die-cast aluminum block with reinforced main bearing caps to minimize weight. Centrifugally cast-iron cylinder sleeves enhance durability. Each journal on the crankshaft is micro-polished to reduce mechanical  friction.

Pistons and Connecting Rods
The TLX's engine has pistons with cavity-shaped crowns that help maintain stable combustion and contribute to improved efficiency. The lightweight pistons have a carefully optimized skirt design to minimize reciprocating weight, which reduces vibration and increases operating efficiency. The pistons are cooled by oil jets directed at the underside of each piston crown. Special cooling channels in the pistons also help modulate engine operating temperatures, while ion-plated piston rings further reduce friction. Lightweight, high-strength steel connecting rods are heat-forged in one piece and then “cold cracked” to create a lighter and stronger rod with an optimally fitted bearing cap.

Cylinder Head and Valvetrain
The direct-injected 2.0-liter VTEC Turbo® has a lightweight, low-pressure die-cast aluminum alloy double overhead cam (DOHC) cylinder head. With the exhaust manifold cast directly into the cylinder head, the use of a separate cast iron exhaust manifold is eliminated, reducing weight and simplifying assembly. The manifold is also liquid cooled to help keep heat in check and has a 4-into-1 design for improved fuel efficiency and responsiveness.

A low-friction, silent chain drives dual overhead cams that activate four valves per cylinder. The cam drive is maintenance free for the life of the engine. To further reduce weight, thin-wall hollow camshafts are used.

To benefit fuel efficiency, emissions and power, the engine uses sodium-filled exhaust valves. A hollow chamber within the valve contains sodium that is cooled by the exhaust port cooling jacket. Since the chamber is close to the valve head, the sodium helps to cool the entire valve; and since the valve is internally cooled, it doesn't need the enriched fuel mixture that is generally used in turbo engines to help cool exhaust valves. The resultant leaner mixture reduces emissions and increases fuel efficiency and power.

The engine uses an advanced valve control system to combine high power output with high fuel efficiency and low emissions. The system combines intake and exhaust Variable Timing Control (dual VTC), which continuously adjusts the intake and exhaust camshaft phasing, with Variable Valve Timing and Lift Electronic Control (VTEC), which changes valve lift, timing and duration of the exhaust valves.

The cylinder head incorporates small, 12-millimeter (M12) sparkplugs, down from the more common 14-millimeter (M14) size, to save space and weight. The head also includes direct-injection multi-hole wide-range fuel injectors with a small-diameter bore. High-pressure direct injection optimizes fuel atomization, allowing for more efficient combustion.

Dual Variable Timing Control (Dual VTC)
Dual VTC adjusts cam timing for the optimal balance of power and efficiency. Based on a range of sensor information, VTC adjusts an oil-control valve, which acts as a hydraulic actuator that can vary the position of each camshaft sprocket relative to the cam it drives. Under light loads, valve overlap can be increased to reduce pumping losses and improve fuel efficiency. When engine speed is low and the engine's workload is high, such as during initial acceleration, the amount of overlap is increased to boost the scavenging effect, which improves torque and responsiveness.

Drive-by-Wire™ Throttle
The TLX's Drive-by-Wire™ throttle uses smart electronics that “connect” the accelerator pedal to a throttle valve inside the throttle body. Acura's Drive-by-Wire™ throttle evaluates and responds to varying driving conditions by monitoring throttle pedal position, throttle valve position, engine speed (rpm) and road speed.

Direct Injection
The TLX's engine features a direct-injection system that enables increased torque across the engine's full operating range, along with high fuel efficiency. The system features a compact, high-pressure, direct-injection pump that allows both high fuel flow and pulsation suppression, while variable pressure control optimizes injector operation. Multi-hole injectors deliver fuel directly into each cylinder, allowing for more efficient combustion.

Low Inertia Mono Scroll Turbo with Electric Wastegate and Intercooler
The TLX's 2.0-liter turbo engine uses a mono-scroll turbocharger with a small-diameter, low-inertia turbine for maximum responsiveness. The mono scroll housing design helps the turbo build boost even at relatively small throttle openings and low engine rpm. The electrically actuated wastegate allows boost pressure to be precisely controlled.

A large, low-restriction intercooler is positioned low in the front of the car where it receives unobstructed airflow. The intercooler helps reduce the temperature of air entering the engine, increasing its density for greater performance. Intake air travels from the air filter, to the turbo compressor, on to the intercooler, then to the engine's intake ports. To reduce weight, the turbo system is plumbed with lightweight resin-composite and aluminum inlet pipes.

Direct Ignition and Detonation/Knock Control
The TLX's Electronic Control Unit (ECU) monitors engine functions to determine the best ignition spark timing. An engine block-mounted acoustic detonation/knock sensor "listens" to the engine, and based on this input, the ECU can retard the ignition timing to prevent potentially damaging detonation. The inline 4-cylinder engine has an ignition coil unit for each cylinder that is positioned above each spark plug's access bore.

Engine Idle-Stop
To help improve fuel efficiency, the TLX is equipped with Idle-Stop capability that automatically shuts off the engine when the vehicle comes to a stop. The engine is automatically restarted when the driver releases the brake pedal after a stop, or pushes the accelerator pedal if the Automatic Brake Hold is active.

The 2021 TLX uses new control logic for more intuitive Idle-Stop operation. Previously, when the driver brought the vehicle to a stop, the engine would automatically stop; however, when the driver selected "P" (Park), the engine would sometimes restart. Now, in this situation, the engine remains off.

Close-Coupled Catalyst
The TLX engine's exhaust manifold is cast directly into the aluminum-alloy cylinder head to reduce weight and complexity, and to position the primary catalytic converter as close as possible to the combustion chambers. The turbocharger is mounted to the exhaust port of the cylinder head, and a high-efficiency catalytic converter mounts directly to the turbocharger turbine exit for extremely rapid converter activation after engine startup.

10-Speed Automatic Transmission
All 2021 TLX models are equipped with a 10-speed automatic transmission (10AT). Engineered for high efficiency with low internal inertia and an exceptionally wide ratio range, the 10AT maximizes the TLX's performance and fuel efficiency. Compared with the previous TLX's 9-speed automatic that was paired with the available V-6, the 10AT has a 3.3-percent wider overall ratio range with a 13.5-percent lower (numerically higher) first gear.  Compared to the previous 8DCT in the 2.4-liter TLX, the new 10AT offers a 59.2 percent wider ratio range and 33.7 percent lower first gear.

The 10AT is designed to be lightweight and compact. It features four planetary gear sets that work together to provide an exceptionally wide ratio spread of 10.139:1 compared with 9.82:1 on the previous-generation TLX V-6's 9-speed unit and 6.37:1 on the previous 8DCT.

The 10-speed also has substantially faster shift performance than the previous-generation 9-speed transmission. For greater responsiveness, the 10AT can make 4-gear direct downshifts, such as from 10 to 6, or from 7 to 3, enabling quick acceleration for merging or passing. To maximize fuel efficiency and minimize engine noise when cruising, 10th gear ratio is an exceptionally tall 1.857:1.

Shift-By-Wire Gear Selector

The 2021 TLX uses a fully electronic, shift-by-wire gear selector. Park, Neutral and Drive are selected with the push of a button. Reverse is selected by pulling back a dedicated switch. Indicator lights on or next to the buttons indicate the mode selected. Also, if the vehicle is brought to a stop in Drive or Reverse, the system will automatically select Park if the driver's seatbelt is unbuckled and the driver's door is opened. Steering wheel-mounted paddle shifters let the driver take manual control of transmission gear selection.

Automatic Modes
The 10-speed automatic transmission can be operated in two fully automatic modes: The D (or “Drive”) mode is ideal for most driving situations and combines fuel efficiency with smooth operation and responsive power when needed. The S (or “Sequential” mode) is meant for more spirited or demanding driving in 1st through 8th gears and features more aggressive shift mapping to keep engine speeds (rpm) higher for greater acceleration and pulling power.

In D mode, the transmission incorporates an advanced Grade Logic Control System, Shift Hold Control and Cornering G Shift Control – all of which reduce unwanted shifting and gear hunting. The result is smart transmission operation that optimizes fuel efficiency and keeps the transmission in the appropriate gear for driving conditions, offering excellent performance and smooth operation.

Grade Logic Control
While ascending or descending hills, Grade Logic Control alters the transmission's shift schedule to reduce shift frequency and improve speed control, helping to minimize driver workload. The transmission ECU continually measures throttle position, vehicle speed and acceleration/deceleration to determine when the vehicle is on a hill. The shift schedule is then adjusted – during ascents to hold the transmission in lower gears to boost climbing power, and during descents to provide greater engine braking.

Shift Hold Control
Shift Hold Control keeps the transmission in its current (lower) gear ratio during aggressive driving, as in the case of decelerating at a corner entry. Shift Hold Control leaves the chassis undisturbed by eliminating excess shifting and ensures that power will be more immediately available (without a downshift) at the corner exit.

Cornering G Shift Control
Cornering G Shift Control monitors the speed of each rear wheel independently to determine when the TLX is turning. When the system detects a sufficient speed differential between the rear wheels, it will suppress any unwanted upshifts. This prevents the transmission from upshifting during a corner which could upset the chassis balance, thus requiring downshifting again at the corner exit when the throttle is applied.

Paddle Shifters
The TLX features dual steering wheel-mounted paddle shifters. Particularly useful in mountainous terrain or during spirited driving, the paddles give the driver greater control over transmission operation. On long downgrades, the driver can command downshifts with the paddles that allow increased engine braking to reduce the load on the brakes and help control the TLX's downhill speed. A-Spec models get paddle shifters with a metal finish.

Paddle Shifter Operation in Drive Mode
While in Drive mode, special transmission logic programming allows the use of the steering wheel-mounted paddle shifters. When the driver operates the paddle shifters, the transmission responds to the driver's shift command and then returns to its normal fully automatic mode if further paddle shift inputs are not made within a few seconds, depending upon driving conditions. This special logic makes it easy for the driver to command a quick downshift without leaving the convenience of Drive mode. This temporary manual mode can be cancelled at the driver's will by holding the right-side paddle for two seconds, and the transmission will resume “Drive.”

Paddle Shifter Operation in Sequential Mode (Sequential SportShift)
By selecting the “S” position, Sequential mode is engaged. This mode offers automatic operation with more aggressive shift mapping and locks out operation of 9th and 10th gears. A pull on either of the paddle shifters places the transmission in fully manual mode until another mode of operation is selected. A digital display in the instrument cluster indicates which gear the transmission is in. The Drive-by-Wire™ throttle system creates a “blip” of the throttle to help match gear speeds while downshifting.

Transmission Operational Backstops
To prevent harm to the powertrain when the transmission is paddle shifted by the driver, the system will inhibit potentially damaging shifts. As an added safety measure, the Electronic Control Unit (ECU) can also cut off fuel to the engine to prevent over-revving. If fuel cutoff is insufficient to prevent engine over-revving, as might be possible when the vehicle is on a steep downhill, the transmission will automatically upshift to prevent damage. On downshifts, the transmission will not execute a driver command that will over-rev the engine.

For improved stop-and-go performance and to help prevent “lugging” the engine, the transmission will automatically downshift even though the transmission has been left in a higher gear as the vehicle comes to a stop.

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

Drivetrain Architecture and Features

Front-Wheel Drive
The TLX offers standard front-wheel drive. With its efficient design and light weight, the TLX with front-wheel drive receives EPA fuel economy ratings of 22 mpg city, 31 mpg highway, 25 mpg combined. The TLX A-Spec with front-wheel drive receives EPA fuel economy ratings of 22 mpg city, 30 highway, 25 mpg combined.

Super Handling All-Wheel Drive System™ (SH-AWD®)
The TLX is available with the fourth generation of Acura's acclaimed Super Handling All-Wheel Drive™ (SH-AWD®), which progressively distributes optimum torque not only between the front and rear axles, but also between the left and right rear wheels for more precise and exhilarating handling response across a wide variety of road conditions.

First introduced on the 2019 RDX, the new 4th-gen SH-AWD® rear differential has enhancements to upgrade its torque capacity and response. Compared to the previous-generation TLX, maximum rear axle torque capacity has been increased by 40 percent. In normal conditions, up to 70 percent of torque can be sent to the rear axle, and 100 percent of that torque can be distributed to either the left or right rear wheels. The rear wheels also receive torque 30 percent faster than the previous-generation TLX.

1 Based on projected 2021 EPA mileage ratings. Use for comparison purposes only. Your actual mileage will vary depending on how you drive and maintain your vehicle, driving conditions and other factors.

When cornering, SH-AWD® distributes more torque to the outside rear wheel, creating a yaw moment to help turn the vehicle through corners – making for more accurate turns, reducing understeer and improving controllability. With cornering forces more evenly distributed between front and rear tires, the ability to utilize more torque is increased – on wet or dry roads. The system also overdrives the rear axle by 2.9 percent, which amplifies the yaw effect of lateral rear-wheel torque distribution when cornering.

Electronic Controls and Parameters
The SH-AWD® system works in cooperation with the TLX's Vehicle Stability Assist™ (VSA®) system and Agile Handling Assist to optimize torque distribution for superior handling and traction utilization. The Electronic Control Unit (ECU) provides information on engine rpm, airflow and transmission gear-ratio selection, while the VSA® ECU provides wheel-speed data. The SH-AWD® ECU also monitors steering angle, lateral g-forces, vehicle yaw rate and electrohydraulic clutch engagement for the right and left rear axle shafts. Drive torque is calculated by the ECU, and then the acceleration, wheel spin, lateral G-force and steering angle are used to determine the front-to-rear torque distribution and the torque split between right and left rear wheels.

SH-AWD® System Layout
The TLX SH-AWD® is a full-time all-wheel-drive system that requires no driver interaction or monitoring, thanks to a torque-transfer unit that is bolted directly to the front-mounted transaxle. The torque-transfer unit receives torque through a spline connection that is part of the front differential housing. A set of helical gear shafts and a hypoid gear set within the torque-transfer unit sends power to the propeller shaft, which in turn transfers power to the rear differential. To optimize the unique packaging needs of the TLX, a "high mount" torque-transfer unit from the front transaxle is used.

The TLX's lightweight SH-AWD® rear differential utilizes an electric motor that powers a pair of hydraulic pumps – one for each clutch pack. A pair of linear solenoids controlled by the Electronic Control Unit (ECU) selectively sends pressure to the clutch packs, which in turn control the amount of power sent to each rear wheel.

The hydraulically operated clutches can be controlled as a pair to alter front/rear torque split, or they can be controlled independently to allow up to 70 percent of available engine torque to go to either rear wheel, which gives the system the unique ability to create yaw moment that increased cornering grip and line traceability.

The fourth-generation SH-AWD® system offers 30-percent quicker front-to-rear torque transfer compared to the third-generation SH-AWD® system, achieved by the adoption of a shorter hydraulic circuit and a higher-torque electric motor that drives the rear differential's twin hydraulic pumps. The hydraulic circuit was also optimized for more consistent response time at the left and right rear wheels.

The TLX powerplant requires no scheduled maintenance for 100,000 miles or more, other than periodic inspections and normal fluid and filter replacements. The first tune-up includes water pump inspection, valve adjustment and the installation of new spark plugs.

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

Final Reduction Ratio



The 2021 TLX has an all-new, model-exclusive body structure, using more advanced lightweight materials, such as aluminum and press-hardened steel, than any previous Acura sedan, providing the foundation for exceptional handling ability, supple ride quality and top-level collision safety performance.

The TLX's exterior body styling was designed to give the car a more authentic, exciting and emotional exterior. Longer, lower and wider, featuring a longer wheelbase with shortened rear overhang, a longer dash-to-axle ratio and an expansive hood, the new TLX delivers “class-above” proportion and stance while maintaining the quick and nimble reflexes of a compact sport sedan.

Premium exterior details include a redesigned Diamond Pentagon grille, all-LED exterior lighting featuring next-generation Jewel Eye™ LED headlights and “Chicane” daytime running lights and taillights, inspired by the ARX-05 Daytona Prototype, as well as standard 18-inch aluminum alloy wheels, with 19-inch aluminum alloy wheels available with the Technology, A-Spec and Advance Packages.

At 113.0 inches, the new TLX's wheelbase is 3.7 inches longer than before, with the added length adding both to the EPA passenger volume (+0.1 cu ft.) and rear legroom (+0.4 in). The longer wheelbase also helps the TLX deliver a more compliant ride over road irregularities. Finally, its more aggressive stance results from a wider body (+2.2 in.) and a wider track (+1.2 in. front and +1.5 in. rear).

Spatially as well as stylistically, the new TLX benefits from a 7.8-inch longer dash to axle dimension—the distance from the forward most portion of the dashboard to the centerline of the front axle—than the prior generation. This serves multiple purposes, including added room for the turbocharged V6 engine in the upcoming TLX Type S and enhancing the new TLX's premium proportions.

The TLX's new body architecture employs advanced engineering and assembly techniques to increase rigidity. Rigidity enhancements include the extensive use of high-performance structural adhesive between inner and outer body panels, and Acura's first use of ultra-rigid cast aluminum front shock tower mounts bonded to a steel body. In conjunction with up-to-100-percent greater suspension mounting point stiffness, these enhancements significantly improve ride and handling and collision safety performance.

Significant use of aluminum helps reduce curb weight, improves rearward weight bias and enhances both handling performance and fuel efficiency. In addition to the cast-aluminum front shock tower mounts, aluminum is used for the front and rear bumper beams, hood, front suspension subframe and, in a first for TLX, the front fenders. (See the Chassis section for more information.)

Next-Generation Design
With its premium proportions and stance and “Alluring Contrast” surfacing, drawing heavily from the Acura Precision Concept and Type S Concept, the 2021 TLX represents the next generation of Acura sport sedan design. Fundamental to the emotional new look are dramatically longer and wider proportions, longer wheelbase and shorter front and rear overhangs, and well-defined wheel arches and soaring character lines.

These bold new proportions are complimented by such striking features as a wider Diamond Pentagon grille, next-generation 4-lamp Acura Jewel Eye™ LED headlights, dramatic new “Chicane” DRLs and bright LED turn signals and taillights, and larger standard wheels and tires.

In the center of the grille, a special composite lens allows millimeter wave radar beams to pass through – wide enough for enhanced pedestrian detection – while also protecting the radar unit from dirt, debris, rain and ice buildup.

Nearly two feet in length, the LED “Chicane” DRLs and the wide, slender 4-lamp Jewel Eye™ LED headlights both sweep dramatically outward and back, dynamically joining the aerodynamic front end with the athletic body's sides. These windswept lines, along with the longer wheelbase make the TLX appear lower and sportier.

Three more functional and stylistic lower openings include a center cooling duct for the engine's 28-inch wide x 6-inch tall turbocharger intercooler; and at each corner are wing-shaped functional air-curtain openings, inspired by those on the NSX supercar. Below, an air splitter lends both form and function.

With an expansive hood and longer wheelbase, the side profile of the new 2021 TLX communicates a more premium, elegant and performance intent design. Its neatly hemmed wheel arches closely frame the standard 18-inch and available 19-inch alloy wheels, while a trio of upswept character lines, bright accents and body-colored door handles give the new TLX a more athletic form. New for the TLX, a laser brazing process that joins the roof to the body side panels creates a clean exterior appearance with no need for a garnish over the roof's rain channels. Further character lines flow along the roof sides, and sweep in with a flourish toward the rear window.

At the rear, the new TLX features slimmer C-pillars that provide better (+0.4 degrees) of over-the-shoulder rear visibility. It also continues the premium design theme with an inventive new “Chicane” LED taillight array. This bold combination LED array begins at the corners of the rear fenders and tapers inwards toward – and onto – the trunk lid. The taillights take the shape of a racing chicane, which is complemented by V-shaped brake-lights on each side. Above are the amber LED turn signals, while the LED backup lights occupy a separate position at the inner portion of the overall array.

Dual polygonal polished stainless exhaust finishers integrate with the lower rear fascia on all 2021 TLX grades, with rear parking sensors included on the Technology Package and Advance Package. For the first time on an Acura model, the rear “A-mark” is placed over a background of gloss black paint (regardless of body color). This unique treatment allows the TLX to cleanly integrate its standard Multi-Angle Rearview Camera, while also positioning it higher than most other sedans, allowing for increased visibility through the rearview camera.

TLX A-Spec: Sport Appearance Package
The TLX A-Spec is distinguished from standard TLX models from all angles by a gloss black surround with matte grey diamonds for the grille, gloss black window surround, gloss black rear license plate garnish and rear diffuser, and 19-inch wheels in a Shark Grey finish. An aggressive gloss black rear trunk lid spoiler is shared with the TLX Type S performance variant. TLX A-Spec models also receive gloss black treatment inside the headlights and taillights for a darkened appearance. Exclusive paint and interior trims are offered on A-Spec models. (See Interior section for more information.)  

Refined Aerodynamics
A comprehensive aerodynamics package helps optimize the new TLX's fuel efficiency, interior quietness and dynamic performance at highway speeds. Air guides direct the airflow through the turbocharger's low-mounted intercooler and the engine's radiator, while the remaining airflow moves over, around and under the vehicle. A cold-air intake is also provided for the engine, delivering the densest, most oxygen-rich ambient air possible.

Computer designed and proven though the use of computational fluid dynamics (CFD) and full-scale wind-tunnel testing, some of the key aerodynamic details include:

  • Minimizing the inlet opening area at the front of the vehicle
  • Small vents built into the front inner fenders create air curtains that help maintain smooth, attached airflow across the wheel openings to reduce drag – while also improving stability in crosswinds
  • Optimized A-pillar dimensions smooth airflow from windshield to side glass and improve forward visibility by 2.7 degrees
  • A molded under-tray located directly beneath the front air dam smoothly initiates the rearward flow of air underneath the vehicle – and as needed, through the engine bay
  • Multi-element strakes deflect airflow around the front tires to reduce drag
  • Dual molded side under-panels improve airflow between the front and rear wheels
  • An angled trunk-lid shape promotes clean air separation from the rear of the vehicle

Rigid New Body Structure
The 2021 TLX's exclusive new body structure is significantly more rigid -- with 50 percent greater global torsional stiffness and up to 100 percent greater rigidity where the suspension mounts to the body -- thanks to the extensive use of advanced materials and computer-aided design and manufacturing methods, as well as the expanded use of structural adhesives, including TLX's first application of high-performance structural adhesives in key areas of the body.

The new structure provides the foundation for the TLX's exceptional ride and handling capabilities, quiet cabin and top-class collision safety performance. The new body was designed to be more rigid and tightly sealed and incorporates numerous new engineering features, including:

  • 64 percent (by weight) application of advanced materials, including aluminum and press hardened steel, the most ever used in an Acura sedan
  • A new high-strength-steel center tunnel
  • New high-strength-steel rear bulkhead ring stiffeners
  • A one-piece, ultra-high-strength steel outer and multi-piece advanced high-strength steel inner door ring design
  • The application of sound-absorbing acoustic spray foam in 10 body cavities, which combine with triple sealed doors and other sound-deadening measures to deliver exceptional cabin quietness
  • The use of high-performance structural adhesive –34.8 meters worth – in the body construction to reduce weight and improve rigidity

Global torsional (twisting) stiffness is increased by 50 percent, which supports high-fidelity chassis responses and allows engineers greater fine-tuning of the suspension system. Locally, front torsional and lateral stiffness are further improved 17.6 percent and 13.5 percent, respectively, supported by triangulated strut bars: two tubular steel bars connecting the upper front suspension towers to the cowl, and a third connecting the front suspension towers. Overall, the stiff body structure allows the chassis to work more effectively and reduces the suspension action needed to control body motion. Another benefit of the rigid body structure is a quiet and more comfortable ride for passengers, with less noise, vibration and harshness (NVH) felt over a wide range of driving conditions.

Advanced High Strength Steel
To aid safety performance and long-term durability, the 2021 TLX utilizes six different grades of press-hardened and high-strength steel (HSS) in 56.4 percent of its body structure by weight. This high-grade, high-tensile strength steel is applied to improve both dynamic handling performance and collision safety while mitigating weight. Altogether, 64 percent of the TLX body is composed of press-hardened steel, high-strength steel or aluminum.

Advanced Compatibility Engineering™ (ACE™) Body Structure
The new TLX's Advanced Compatibility Engineering™ (ACE™) body structure is designed to enhance occupant protection and crash compatibility in frontal collisions. It uses a network of connected structural elements to distribute crash energy more evenly throughout the front of the vehicle, helping to reduce the forces transferred to the passenger compartment. ACE channels frontal crash energy to both upper and lower structural elements, including the floor frame rails, side sills and A-pillars. It can help to more evenly disperse the forces transferred to other vehicles in a crash as well.

ACE™ also helps reduce the potential for override in collisions between two vehicles of differing heights. ACE goes further by offering additional strength and protection in small overlap frontal collisions, which are among the most severe. (See the Safety and Driver Assistance section for more information.)

Crash Stroke
The TLX's ACE™ body structure features crash stroke technology. In a severe frontal collision, the lower section of the front vehicle frame is designed to deform in a manner that helps direct the engine downward to minimize cabin intrusion.

Center Tunnel Load Path
To help the 2021 TLX meet the anticipated new oblique frontal crash test evaluations by the NHTSA, the central floor tunnel was specially engineered and uniquely attached to the lower dashboard to help absorb these loads. The design channels some oblique frontal crash loads through the tunnel instead of the passenger foot area. To accomplish this, four tunnel caps made of advanced high-strength steel (780 and 980 grade) extend from the lower dash rearward past the front seats.

Similar in concept, rear crash load paths begin at the rear bumper and extend through the trunk floor and rear wheel wells and into the side sills.

Ultra-High Strength Door Rings
The 2021 TLX features ultra-high-strength-steel door reinforcement beams and one-piece outer ultra-high-strength front door rings made of 1500-MPa press hardened steel. Laser welded and significantly stronger than conventional steel, the ultra-high-strength steel reinforcements are designed to help better protect occupants in a frontal or side impact.

High-Performance Structural Adhesive
The 2021 TLX makes widespread use of structural adhesives – 34.8 meters in total – throughout the unibody, supplementing structural welds and significantly increasing rigidity and aiding collision performance. Applied before certain overlapping body panels are welded together, the high-performance adhesive material is used in the front suspension towers, front side frames, rear side sills, A-, B- and C-pillars, roof panel, central roof arch, rear wheelhouses, rear floor pan, and lower rear unibody corners.

Rear Ring Structure
New rear bulkhead ring stiffeners increase body rigidity while simultaneously reducing weight (-17.7 lbs.) and contributing to a 10 percent larger (by area) cargo pass-through opening with the rear seatbacks folded flat. The advantage lies in the new ring's welded structure in place of two bolt-on gussets in the previous model.

Hemmed Rear Wheel Arch
Instead of typical spot welds, the TLX's rear wheel arches are finished with a roll-hemming process for an especially clean edge. The process allows a reduced tire-to-fender gap that improves aerodynamics, and offers a smoother, more refined appearance.

Cast Aluminum Front Shock Tower Mounts
The 2021 TLX's cast aluminum front shock tower mounts are a first for Acura. Compared to typical steel mounts, these lightweight castings provide a more rigid upper mounting point for the suspension, which improves the operating efficiency of the damper, allowing engineers to optimally tune suspension performance for sharper handling and improved ride compliance.  The new mounts also aid in the reduction of vibrations transmitted into the cabin and contribute to the new TLX's front-to-rear weight bias. The mounts attach to the steel unibody using structural adhesive and self-piercing rivets.

Shock Tower Braces
Additionally, tubular steel braces connect the left and right towers to each other and with the top of the cowl. Triangulating these structures improves torsional stiffness by 17.6 percent and front lateral stiffness by 3.5 percent, with minimal additional mass. This stiffening provides multiple benefits, including the ability to more finely tune the suspension, and further improvement in both handling sharpness and ride quality.

Underbody Bracing
TLX models equipped with Super Handling All-Wheel Drive™ (SH-AWD®) receive additional underbody bracing to improve dynamic performance. These stamped steel braces increase rear torsional stiffness 7.9 percent, rear lateral stiffness 11 percent, and rear bending stiffness 4.6 percent. These underbody braces triangulate the vehicle's floor structure with the rear differential mount. A stamped steel brace is also added to the front subframe on all SH-AWD models as well as front wheel drive TLX's with A-Spec or Advance Packages. 

Noise, Vibration and Harshness (NVH) Design Features
Extensive noise, vibration and harshness (NVH) features include strategically placed body sealants, structural adhesives and other measures to reduce vibration and the transmission of noise.

Wind and Exterior Ambient Noise Reduction

  • Dual 360-degree molded door seals reduce wind noise and improve isolation.
  • Door gap seals at all door edges further keep wind noise from entering the cabin.

Acoustic Spray Foam
The application of acoustic spray foam provides extra sound insulation by blocking off hollow pillars, which reduces the transmission of wind and road noise into the passenger cabin. The foam, applied to five locations on each side of the body (10 total locations) is heated and injected into:

  • The base of the A, B, and C pillars
  • The base of the windshield frame
  • The unique pillar structure above the rear damper

The application process is automated and computer controlled, with the foam curing in 7 to 11 seconds after application, for a highly precise and consistent process.

Sound Deadening Materials
The new TLX has widespread application of sound-deadening material and other insulation throughout the unibody to reduce wind, road and engine noise.

  • High-density, sound-deadening “melt sheet” is used in key areas of the floor, including in the front footwells, beneath the front seats, in the rear footwells, and beneath the rear seats.
  • Additional sound-deadening material is used in the lower dashboard and inside the trunk.
  • The Advance Package has additional sound-deadening material, including inside the front wheel wells, under the floors, and inside the rear wheel wells.

Recycled Materials
Nearly 50 percent of the material used in the TLX's sound-insulating panels used for the hood, center tunnel, inner-dashboard and rear wheel liners is made from lightweight post-industrial textile waste and post-consumer plastic bottles (3.6 pounds and 1.3 pounds, respectively).

  • To create the hood, center tunnel and dashboard insulators, bales of textile waste are shredded into textile fibers, volumized, made into sheets, and then molded into specific shapes.
  • To create the wheel liners, bales of recycled PET bottles are pelletized, extruded into fibers, mixed with other fibers, and then molded into specific shapes.

Acoustic Glass
Laminated acoustic glass is used for the TLX's windshield to help reduce noise entering the cabin. Tuned specifically to help attenuate wind-noise frequencies, the windshield glass uses an outer layer of 2.0 mm thick safety-glass, a 0.7 mm thick middle layer of acoustic polyvinyl butyl (PVB), and a 1.8 mm thick safety-glass inner layer, for a total thickness of 4.5 mm (variable thickness between 4.5 to 4.9 mm on the Advance Package, due to the unique requirements of the HUD windshield). The windshield blocks 100 percent of UV light rays.

The TLX has 5 mm thick tempered front door glass and 4 mm thick tempered rear door glass. The tempered rear-quarter glass and tempered rear window glass are 4 mm thick, and are 0.5 mm and 0.9 mm thicker, respectively, than in the 2020 TLX.

Exterior Lighting
Next-Generation Acura LED Lighting
The 2021 TLX incorporates light-emitting diode (LED) exterior lighting throughout, including new “Chicane” LED Daytime Running Lights (DRL), new Jewel Eye® LED headlights with four light elements on each side, LED side marker lights, “Chicane” LED taillights, and LED turn signals (including LED side mirror-mounted turn signals). Additionally, LED fog lights are included with the A-Spec and Advance Package.

Chicane LED Daytime Running Lights (DRL)
The TLX has new “Chicane” LED Daytime Running Lights (DRL) positioned below and outside the Jewel Eye™ LED headlights. In addition to enhancing safety, the new DRLs' shape identifies the TLX at a glance. Taking inspiration from Acura's championship-winning ARX-05 race car, the taillights are also shaped to enhance the premium stance of the new TLX.

LED Jewel Eye™ Headlights with Auto On/Off
The 2021 TLX's new LED Jewel Eye™ headlights provide a significant advance in performance compared to the previous generation TLX, while offering dramatically better nighttime illumination and visibility than both high-intensity discharge (HID) headlights and traditional halogen headlights.

Incorporating four lighting cells per side, with each cell including a low- and high-beam LED, the new low-beam headlights provide 15 percent longer reach and 35 percent greater width in illumination. Meanwhile the high beams have 10 percent longer reach and 40 percent greater width in illumination. Whenever the headlights are turned on, regardless of whether low- or high-beams are activated, all four lighting cells illuminate, providing a consistent appearance at the front of the vehicle.

Besides improving driver confidence and active safety, the LED headlights use less energy, helping to enhance fuel efficiency by reducing engine loads. In addition, the LED headlights last up to three times longer than HID headlights and up to six times longer than halogen headlights – contributing to less frequent replacement. An auto on/off function is included, and the low-beams illuminate momentarily when the doors are unlocked at night.

Auto High-Beam System
The new 2021 TLX's standard auto high beam system uses a camera located on the windshield to continually scan for oncoming traffic. The system illuminates the high beams except when oncoming or proceeding traffic is detected and then automatically switches to the LED low-beams. Requiring no intervention or action from the driver, the auto high beam feature significantly improves nighttime illumination for enhanced active safety and a high level of driver confidence.

The system functions when the headlight switch is in the Auto position and may be disabled and reactivated by a quick pull on the high-beam stalk. A green headlight icon with an "A" appears on the instrument panel when the system is functioning. The auto high beam feature automatically disengages during rainy conditions, when low beam lighting is preferable. Auto high beam deactivates with continuous wiper operation and reactivates when wiper operation is ceased.

Driver-Focused, Premium Cockpit Design
The all-new TLX interior builds on the “Acura Precision Cockpit” design language, with premium detailing, intuitive functionality and flowing lines. Dramatic styling elements sweep through the cabin, dividing the front seating into dual personal spaces, with Acura's award-winning True Touchpad™ Interface positioned within easy reach on the center console and the Integrated Dynamics System selector dial prominently positioned in the center section of the instrument panel. Fit and finish have received close attention throughout, with high-quality, soft-touch materials and available perforated Milano leather. Standard genuine aluminum accents give the TLX cabin an advanced, technical appearance, while the interior of the TLX with Advance Package is warmed with the look and feel of genuine open-pore European Ash wood or American White Oak.

First-Class Front Seat Comfort
The meticulously tailored cabin takes advantage of the wider body design to offer expanded hip and shoulder room, providing first-class accommodations for front-seat occupants (up 0.5 and 0.7 inches, respectively). The body's roof pillars have moved rearward, providing a more commanding forward view (+2.7 degrees). Rear legroom is also improved (+0.4 inches), while rear head, hip and shoulder room are nominally reduced to accommodate the more tapered greenhouse.

For greater cargo carrying utility, the standard, lockable 60/40-split and folding rear seatbacks reveal a 10 percent larger (by area) pass-through opening. The trunk offers 13.5 cubic feet of cargo space, - near the top of the model's competitive set.

NEW: Acura Sport Seats
The TLX's front bucket seats are a new-generation design that made its debut in the 2019 RDX. Designed to provide luxurious comfort, combined with secure lateral support for aggressive driving, they utilize an ultra-high-strength steel frame for low weight and high rigidity. The seats provide comfortable support for a wide range of body types, along with greater adjustability than ever before.

The front seats in TLX, offer standard 12-way power adjustability, including 4-way power lumbar adjustability and new 4-way adjustable headrests. In the TLX with Advance Package, the front seats deliver class-leading 16-way power adjustability, adding 2-way power-adjustable side bolsters and thigh support. In addition to the conventional seat control switches located on the outboard side of each front seat base cushion, the TLX with Advance Package adds an on-screen seat control interface for added convenience.

Heated front seats are standard in all TLX models. An algorithmically controlled ECU allows for three temperature settings, along with fast warm-up and smooth, precise temperature control. The TLX A-Spec and TLX with Advance Package add three-mode ventilated front seats with an Auto climate function.

NEW: Head-Up Display
For the first time, the TLX with Advance Package features a large 10.5-inch color Head-Up Display (HUD), which projects a broad range of customizable information displays on the lower portion of the windshield in the driver's line of sight. The driver can adjust the location (up and down) and the brightness of the projection or turn off the system via switches on the instrument panel.

Display modes can be selected using steering wheel-mounted controls. Display modes include:

  • Vehicle speed
  • Current mode for Adaptive Cruise Control and Lane Keeping Assist System
  • Turn-by-turn directions
  • Traffic sign recognition

NEW: Drive Mode Dial
Positioned just below the climate controls, the TLX's large Drive Mode Dial takes direct inspiration from the NSX and makes it easy to quickly select one of three distinct driving modes, Comfort, Normal and Sport. Rotate the dial left or right to select the desired driving mode. An on-screen animation and interior ambient lighting (Technology Package and above) confirms each mode selection. In addition, TLX is the first Acura model to feature an Individual Mode – allowing the driver to tailor a personalized set of dynamic characteristics. (See the Chassis section for more information.)

NEW: IconicDrive™ Selectable LED Ambient Lighting
The 2021 TLX with Technology Package offers the most expressive interior lighting technology in Acura's history, with the availability of a total of 27 different interior ambient lighting schemes — selectable through the Integrated Dynamics System and the True Touchpad Interface. In TLX models with the Technology Package or above, LED accent "light pipes" trace character lines along the front doors and down the sides of the center console. Based on the mode selected (Comfort, Normal, Sport or Individual), the color of the light pipes, ambient lighting in the footwells and door-pull pockets changes—setting a unique mood that becomes more defined as darkness falls.

The standard Comfort, Normal and Sport driving modes have default color themes (Blue, White and Red respectively). The "Individual" mode allows the user to choose any of those three colors as an "Individual" favorite, or pick between one of 24 other color theme combinations that are inspired by some of the world's great destinations and racetracks. A specific lighting theme can also be set as a driver preference with further changes disabled even if the drive mode is changed.

NEW: Genuine Wood Interior Accents
For the first time, the TLX offers genuine wood interior accents with the Advance Package. The sustainably sourced dark open-pore European Ash wood and blonde open-pore American White Oak have a low-gloss finish to better display the character of the wood. The wood accents sweep from the front doors, appearing to flow behind the instrument panel and arc down the sides of the center console.

TLX A-Spec: Sport Appearance Package
Interior enhancements for the TLX A-Spec include a flat-bottom steering wheel with A-Spec badge, perforated leather and red contrast stitching. The TLX's standard steering wheel mounted paddle shifters are metal finished, and the satin silver gauges feature red illumination. Additionally, metal door sill plates, metal sport pedals, a black headliner and embossed aluminum interior accents further distinguish the TLX A-Spec interior.

The TLX A-Spec can be equipped with either Red or Ebony Milano-leather wrapped seats, both accented with premium black Ultrasuede® inserts, providing comfort and breathability during performance driving. In addition to style, the Ultrasuede material used in the TLX contributes to sustainability, with 30 percent of the polyester used in its creation coming from molasses, a waste product of sugar refining. This sustainable, plant-based raw material is processed to create polymers indistinguishable from those made using petrochemicals. The environmental benefits are substantial, with about 2.2 lb. (1 kg) of greenhouse gas emissions saved for every 2.2 lb. (1 kg) of Ultrasuede produced, or a savings of about 1 pint (0.47 liter) of crude oil (the raw material for petroleum-based polymers) for every square meter of material produced.

Interior Colors and Materials
The TLX's luxury interior palette is sophisticated and coordinated, and is offered in Ebony, Greystone, Parchment and Espresso color schemes. Two performance-themed interior colors are offered in the TLX A-Spec: Ebony and Red, both with black Ultrasuede® inserts.

Seating material in the TLX is in keeping with the sedan's performance/luxury mission. Synthetic leather is standard in the TLX. In the TLX with Technology Package, A-Spec and Advance Package, special full-grain Milano leather is used. Made with young North American hides, this leather has a more premium look and feel and gives the seats a long-lasting, precisely tailored look. In the A-Spec, black premium sustainable Ultrasuede® perforated center panels help keep passengers in position during aggressive cornering and improve breathability.

Comfort and Convenience Features

Remote Smart Entry Door Handles
All 2021 TLX models offer the convenience of Smart Entry front door handles. The Smart Entry system simplifies approaching, entering and operating the TLX – especially when the driver has their hands full. To gain entry to vehicle, the driver simply pulls one of the two front door handles while the remote is in their possession. TLX models with the Technology Package add Smart Entry to the rear doors.  

Unique Driver Preferences
All TLX models come with two keyless remotes with unique identifiers. Each remote can be set with unique profiles to accommodate the individual preferences of two different drivers. The available preferences include driver seat and mirror positions, along with select HVAC functions. Other preferences include turning entry lights on or off, audio system pre-sets, air conditioning preferences, and navigation system settings. In the event both owners use the vehicle at the same time, the TLX will recognize the keyless remote that approaches the driver's door first.

Auto High-Beam System
The TLX's standard auto high-beam system makes optimal use of the vehicle's headlights. When the headlight switch is set in the Auto position, the system automatically illuminates the high beams until an integrated camera detects oncoming or proceeding traffic and automatically switches to low beams. (See the Body & Exterior and Safety & Driver Assist sections for more information.)

Multi-Angle Rearview Camera
A multi-angle rearview camera is standard on the TLX. Its wide-view format significantly expands the driver's rearward visibility when the camera is in use, increasing convenience and peace of mind. (See Safety & Driver Assist sections for more information.)

Surround-View Camera System
In the TLX with Advance Package, four exterior cameras provide a 360-view of the space immediately around the vehicle through the audio/information display. A camera button conveniently located on the end of the turn signal lever changes camera views. (See Safety & Driver Assist sections for more information.)

Dual-Zone Automatic Climate Control
All TLX models feature a dual-zone automatic climate control system that lets the driver and front passenger set temperatures to their individual liking. Technology, A-Spec and Advance Packages add a GPS-link for still better control of individual settings. For the comfort of rear seat passengers, adjustable dual vents are provided in the rear of the center console.

With its position-sensing ability, the GPS navigation system (TLX with Technology Package) contributes to overall passenger comfort with a 3D solar sensing feature. Based on continuously updated vehicle position information, the navigation system determines the position of the sun relative to the driver and front passenger. Combining this information with input from a solar sensor located on top of the instrument panel, the climate control system automatically adjusts cooling/heating and airflow from side to side as needed to compensate for asymmetrical solar heating. On the A-Spec and Advance Packages, the heated and ventilated front seats are electronically linked to the climate control system, expediting the transition to the desired temperature.

Audio and Connectivity

NEW: Acura True Touchpad Interface™
The all-new 2021 TLX features Acura's most advanced user interface yet. The True Touchpad Interface™ features a 10.2-inch full-HD display mounted high atop the instrument panel close to the driver's natural line of sight, a dual-zone touchpad with absolute position mapping, and a powerful Android-based operating system with customizable app tiles. For more intuitive operation, the TLX features new console mounted Power, Volume and Seek controls just to the right of the touchpad, where they fall readily to hand without a long reach.

TLX's True Touchpad Interface combines the best elements of a conventional touchscreen with those of a remote-based interface. A traditional touchscreen is intuitive and direct – what you see is what you press – but the placement of the screen is out of the driver's natural line-of-sight. A remote interface solves this problem, but the interaction between the remote and display is often clumsy.

Unlike existing remote interfaces that operate like a computer trackpad, every spot on the TLX's touchpad is mapped precisely – one-to-one – with the corresponding position on the large center display – as the world's first application of “absolute positioning” in the driving environment. For instance, a tap on the top left corner of the touchpad corresponds precisely with the action on the top left of the center display. This arrangement can greatly reduce or even eliminate the need to visually confirm the desired command, thereby helping drivers keep their eyes on the road.

All elements of the True Touchpad Interface™, including simple, clean graphics and menu structures, were designed in concert to work seamlessly with one another. The TLX's new onboard natural language voice recognition system dramatically improves the ease and intuitiveness of voice commands in the vehicle, plus handwriting recognition ability in the True Touchpad Interface offers an alternate input method. Additionally, the available interactive Head-Up Display (HUD) compliments the system and provides drivers with a new level of situational awareness.

Research and development of the prototype touchpad, as originally introduced in the 2019 Acura RDX, was validated by tens of thousands of hours at The Ohio State University's world-class Driving Simulation Laboratory established with the help of Acura's Ohio R&D Center. In the process, it was discovered that, on average, drivers become acclimated and comfortable with the touchpad system in just minutes.

Three Available Audio Systems
For the first time, the TLX offers three distinct levels of audio performance depending on trim. Along with a physical knob for power and volume and hard keys for forward and backward station seek, the full range of audio system controls can be accessed using the True Touchpad Interface™ positioned within easy reach of the driver and front-seat passenger. Controls for key audio system functions are also positioned within fingertip reach on the left side of the TLX's steering wheel.

All three available TLX audio systems offer a variety of source options including AM, FM, HD Radio™, SiriusXM®, Bluetooth Audio, USB connected device (iPod) as well as cloud-based services.

Acura 10-Speaker Audio System (Standard)

The 2021 TLX comes standard with a 450-watt Acura premium audio system with 10 speakers strategically located throughout the TLX cabin. Each front door has a 3.5-inch full-range speaker and a larger 6.7-inch driver. A pair of 3.5-inch full-range speakers are positioned on the rear parcel shelf. Separate 1.1-inch tweeters are positioned near the A-pillars.

New for 2021, the TLX features a pair of upward-facing Twin Telford™ 5-inch subwoofers positioned in the outside corners of the rear parcel shelf. These subwoofers are uniquely canted inward at an opposing 13.5-degree angle. This innovative design helps to reduce unwanted rattle or buzz in the supporting structure and allows the Twin Telford™ subs to deliver focused, low distortion bass extending to 20Hz.            

ELS STUDIO® 13-Speaker Premium Audio System (Technology Package)

The TLX with Technology Package features a 13-speaker, 550-watt ELS STUDIO® system that is engineered to offer impressive sound quality from a wide range of media formats. Building on the 10-speaker layout found in the TLX, two additional 1.1-inch by 4-inch Highline™ ultra-slim overhead speakers are added in the front portion of the headliner and a 3.5-inch center-channel full-range speaker is placed atop the instrument panel. An external amplifier with patented Acoustic Motion Control™ provides 12 channels of amplification.

Engineered specifically for the TLX, the system delivers highly detailed, well-balanced sound to all seating positions. The system gets its name from multi-Grammy® Award winning producer/engineer Elliot Scheiner's recording industry-recognized moniker "ELS."

NEW: ELS Studio 3D™ 17-Speaker Premium Audio System (A-Spec, Advance Package)
The TLX A-Spec and TLX with Advance Package feature a state-of-the-art 710-watt 17 speaker, 16-channel ELS STUDIO 3D™ Audio System. Building on the 13-speaker system, the 3D system features four Highline™ ultra-slim overhead speakers in the vehicle's headliner. An additional 3.5-inch driver is positioned in each rear door. An upgraded external amplifier with patented Acoustic Motion Control™ provides 710 watts of system power, delivered through 16 discrete channels.

With three-way front cabin sound architecture and user selectable Multi-Zone Audio, the sound image can be personalized to meet the desires of the sedan enthusiast's individual tastes. Even the rear seat passengers are treated to an expansive soundstage utilizing 9cm rear door speakers, two Highline® overhead speakers, two 9cm rear surrounds and the Twin Telford subwoofers, mounted at an inward-facing angle on the rear parcel shelf to mitigate vibration.  This level of audio performance is a new benchmark for Acura sedans.

Engineered by Elliot Scheiner, the 3D system is designed to create an immersive sound stage experience that, thanks to the full array of Highline™ ultra-slim overhead speakers, seems to be suspended in mid-air. The result is a powerful listening experience that brings studio-quality sound to the TLX.

This sophisticated speaker array offers multi-zone audio, with selectable speaker level optimization. The system allows optimized privacy sound zones for the driver, for the front seats, or rear seats. In addition, the 3D system is fully integrated with the Bluetooth® HandsfreeLink® phone system to use the overhead speakers for a new level of hands-free phone clarity.

NEW: Acura Navigation System with Natural Language Voice Recognition
The 2021 TLX with Technology Package features an all-new integrated Acura Satellite-Linked Navigation System with natural language voice recognition using GPS technology to provide drivers with turn-by-turn guidance to their chosen destination (available in all 50 United States as well as Puerto Rico, Canada and Mexico).

The TLX's navigation system, developed in cooperation with HERE, offers many improvements, including enhanced graphics, 3D buildings, turn-by-turn directions displayed in the instrument cluster and more.

An HD Digital Traffic feature, which alerts the driver to current traffic conditions and can display alternate routes around gridlock. It features expanded coverage including many surface streets within the U.S., allowing the driver to choose faster, less congested routes. HD Digital Traffic is subscription-free.

The navigation system can be controlled by voice or the True Touchpad Interface™. TLX's new, enhanced natural-speech voice-recognition system can respond to more casual command phrases that require less user familiarization, in addition to the previous capability of being able to understand spoken city and street names.

Using Eyes Free mode, Siri takes hands-free functionality even further and helps to minimize potential distractions by keeping the iOS device's screen from lighting up.

SMS Text Messaging
All TLX models have a standard SMS text message function that can read incoming texts aloud over the audio system and allow the driver to reply with any of six factory preset messages.
To minimize the potential for driver distraction, the text of the incoming message is not displayed on screen unless the transmission is in Park.
Bluetooth® HandsFreeLink®
The Bluetooth® HandsFreeLink® interface is designed to offer hands-free operation for many Bluetooth®-enabled mobile telephones. Standard on all TLX models, the system wirelessly connects the driver's cell phone to the vehicle's audio system. This allows the driver to make or answer cell phone calls without removing hands from the steering wheel. The system is compatible with Bluetooth®-enabled cell phones that have the Hands Free Profile (HFP).

USB Ports and Power Outlets
All TLX models have two 12-volt power outlets, one in the center console and a second on the center console side pocket, near the passenger footwell. In addition to a traditional AUX input jack, the TLX offers two 2.5-amp USB ports inside the center console. One of the 2.5-amp USB ports allows connectivity to items such as an iPod® or iPhone®, or a removable flash drive storage device containing WMA, MP3 or AAC format music, or simply for charging. This USB port is also used for CarPlay® or Android Auto™ connection. The other 2.5-amp USB port is used only for charging.

Center Console Connectivity and Storage
The TLX's new center console is a key design element of the interior, both stylistically and functionally. It integrates the bold theme lines that run through the doors and instrument panel and is finished in high quality materials including authentic metal or authentic wood trim panels. The console maximizes driver and passenger comfort with a padded armrest. There is also a padded hand rest built into the console, designed to help support the driver's hand when using the True Touchpad Interface™.

Substantial design effort went into incorporating smart storage features to make daily use simpler. Side pockets are positioned on either side of the forward portion of the console—perfect for smaller items like phones, wallets or keys. Two large cup holders are positioned on top of the console for easy access, alongside a rubberized tray for a phone; in A-Spec and Advance Package models, the tray incorporates a new faster wireless charging for compatible devices. Inside the 3.5-liter console, is a USB port for Apple CarPlay™ or Android Auto™ connectivity, along with an AUX input jack, 12-volt power outlet, and an additional USB port in the center console for device charging.

2021 TLX: Chassis

The new model-exclusive chassis architecture for the 2021 TLX combines with a more rigid body structure to provide the best balance of ride comfort, agile handling and a precise driving feel. Steering is quicker, cornering capability is higher, body motion control is better, and braking performance is stronger.

The TLX's longer wheelbase, greater front and rear track widths, improved front-to-rear weight balance, new double-wishbone front and 5-link rear suspension systems, and increased wheel and tire sizes further contribute to these ride quality and performance gains.

Additional major chassis technologies include a new belt-driven, variable-ratio, rack-and-pinion Electric Power Steering (EPS); and an Acura NSX-derived, electronically controlled electro-servo brake system for excellent feel and feedback under all driving conditions; and available 4th-generation Super-Handling All-Wheel drive for improved handling capabilities in all weather and road conditions.

What's New:
The following Chassis features are new for the 2021 TLX:

  • Double-wishbone front suspension
  • Five-link independent rear suspension
  • Bonded stabilizer bar bushings
  • Sensor-controlled Adaptive Damper System (Advance Package)
  • Belt-Driven Variable-Ratio Electric Power-Assisted Rack-and-Pinion Steering (EPS)
  • Electro-Servo Brakes derived from NSX
  • Four-mode Integrated Dynamics System
  • Cast aluminum front subframe
  • Wider, noise-reducing aluminum alloy wheels (+0.5 in. on 18-in. wheels, +1 in. on 19-in. wheels)

Front and Rear Suspension
The 2021 TLX suspension delivers both agile handling and a composed, supple ride. The system uses a combination of new front double-wishbone design and a rear 5-link design, with a front rigid aluminum subframe and a rear steel subframe. In front are lower hydraulic suspension bushings to enhance ride compliance. The TLX, TLX with Technology Package and A-Spec use 2-stage Amplitude Reactive Dampers, while the TLX with Advance Package employs a sensor-controlled Adaptive Damper System.

The new 5-link rear suspension provides outstanding handling characteristics and ride quality, while also helping to maximize second-row seating and cargo space. TLX models equipped with front-wheel drive feature a 29.5 mm solid front and 20 mm solid rear stabilizer bars, SH-AWD models feature a larger, 20.5 mm rear stabilizer bar. The solid rear stabilizer bars improve turn-in response while reducing body roll during cornering. New for the 2021 TLX, the stabilizer bars are bonded to their mounting bushings and use low-friction connecting links for smooth operation.

NEW: Front Double Wishbone Suspension
The 2021 TLX's front double wishbone suspension is engineered to provide inspired handling performance and a responsive feel. Lateral stiffness is up 85 percent in front and 45 percent in the rear of the double-wishbone system, when compared to the previous TLX's MacPherson strut design. Specially calibrated geometry ensures the optimal tire contact patch under all driving conditions – and in particular at-the-limit cornering – giving the new TLX improved steering response, feel, precision and grip.

The front suspension has been optimized with compact and high-strength components, including lightweight forged aluminum lower wishbones. The upper wishbone is stamped steel, and the steering knuckle and lower damper fork are cast iron. The suspension geometry is specially tuned to yield communicative on-center steering feel and excellent response and stability. The system also minimizes steering disturbances, such as torque steer and road kickback through the steering wheel.

Hydraulic Suspension Compliance Bushings
The forged-aluminum lower suspension arms are connected to the body via specially tuned hydraulic compliance bushings in aluminum carriers. This design provides the ideal combination of ride quality, handling responsiveness and precision, and maximum isolation from road noise, vibration and harshness (NVH) inside the vehicle.

NEW: Cast Aluminum Front Subframe
The TLX employs a cast-aluminum front subframe to reduce road surface vibration and shock inputs for a smooth, quiet ride. Lightweight and rigid, the front subframe supports the engine, transmission, front suspension and steering system. In conjunction with the hydraulic compliance bushings, this aluminum casting reduces vertical and fore/aft forces felt at the front seats, while also contributing to better front-to-rear weight distribution, improved handling and greater fuel efficiency. The previous-generation TLX utilized a “hybrid” aluminum and steel design.

NEW: Five-Link Rear Suspension
The 2021 TLX's new 5-link rear suspension system offers both ride compliance and handling performance significantly above the previous generation, putting the TLX in the same league dynamically as top European competitors. This new multi-link system uses two forged aluminum and three steel control arms to minimize unsprung weight and optimize component stiffness, and an aluminum hub carrier. Improvements to the TLX's unibody stiffness – particularly in the rear area – help the new suspension system excel at improving stability, ride compliance, and impact harshness. The system is designed to perform ideally in both FWD and SH-AWD® configurations.

Amplitude Reactive Dampers
Amplitude Reactive Dampers (ARD) are used on the TLX, TLX with Technology Package and TLX A-Spec. Amplitude Reactive Dampers contribute to outstanding ride comfort together with crisp, precise handling. The dampers operate in two distinct performance parameters, including a Ride Zone and a Handling Zone. Each zone has a unique set of compression and rebound damping forces tailored to provide the desired ride and handling attributes. In essence, the amplitude reactive dampers operate like two separate suspension systems combined in one. The dampers function reactively or "passively," and are entirely mechanical/hydraulic in operation with no electronics required.

NEW: Sensor-Controlled Adaptive Damper System (ADS) (Advance Package)
Newly available in the TLX with Advance Package, the Adaptive Damper System enables active and customizable control of damper response using information from the Vehicle Stability Assist (VSA) system's wheel sensors, yaw/G sensors, engine rpm and torque values, steering angle, and damper-stroke sensors, to adjust damping response every 0.002 seconds to adapt to both varying road conditions and driver inputs.

The Adaptive Damper System is a part of the vehicle's Integrated Dynamics System. As directed by the driver's choice of Comfort, Normal or Sport, an electric actuator integrated into each damper governs hydraulic fluid movement inside the unit progressively increases damper stiffness.

At the driver's preference, Comfort or Normal mode may be set as the default upon vehicle startup and is linked to each key fob.

NEW: Belt-Driven Variable-Ratio Electric Power-Assisted Rack-and-Pinion Steering (EPS)
The new TLX's belt-driven Electric Power Steering (EPS) uses a high-output electric motor to increase the torque available for steering assist. This high capacity is essential for delivering an even faster steering response than offered by the previous-generation TLX. The new EPS system's variable gear ratio system is designed and tuned to provide the most essential characteristics in a luxury sport sedan's steering, including:

  • Instantaneous response
  • Smooth and natural, direct and precise steering feel
  • Agile low-speed maneuverability for city streets and parking
  • High-speed stability and predictability for highway travel
  • Quiet operation

The system's variable steering ratio is enabled by a steering rack with progressively wider gear-tooth spacing, so as the steering wheel is turned further off center, the steering ratio is quickened. The new TLX steering system delivers a 15 percent quicker initial response at center and up to 22 percent quicker response as steering input increases (as the steering wheel is turned farther from center). The electric steering system's ECU is calibrated with the Integrated Dynamics System to increase steering weight in the Sport mode.

Rigid Steering Column
The TLX steering column is a highly rigid design with a one-piece steel mounting bracket and two radial bearings. The resulting stiffness gives maximum driver steering feedback along with minimizing vibration felt in the wheel. The TLX features manual tilt and telescope steering wheel adjustment. The telescoping adjustment range was increased by 20mm, allowing for an enhanced driver-focused seating position.

NEW: Electro-Servo Brakes
Inspired by the Acura NSX supercar, the TLX's new electro-servo brake system is hydraulic from the master cylinder to the 4-wheel disc brakes, just like a traditional braking system. The key difference is that the braking function is electronically controlled rather than a purely mechanical activation. The system offers excellent feel and feedback for the driver through the brake pedal.

When the driver applies the brake pedal, a signal is sent to the vehicle's Electronic Servo Brake ECU, which determines the appropriate amount of braking force to be applied by the hydraulic braking system. As in a traditional braking system, a hydraulic master cylinder then pumps brake fluid through the system; however, midway between the master cylinder and the calipers is a separate motorized electronic actuator, the same actuator used in the NSX. This actuator receives an electronic signal, generated in the master cylinder module, that measures how the driver has applied the brakes – soft or hard, slow or fast – and precisely defines how much  hydraulic pressure is apportioned to the brake calipers at each wheel. The system provides a consistent, linear, and predictable brake pedal feel, regardless of driving conditions.

An additional benefit of the TLX's electro-servo brakes is the ability for engineers to finely tune the brake pedal force and electronically control the brake pressure to optimize pedal feel and braking performance for a premium sport sedan driving experience.

Four-Wheel Disc Brakes with ABS
Four-wheel disc brakes with 4-channel anti-lock braking system (ABS), electro-servo brake system (ESB), electronic brake force distribution (EBD) and brake assist are standard on the 2021 TLX. The system provides confident stops with a short-travel, firm pedal feel. The result is a comfortable and refined braking feel at low speeds, predictable and easy operation on the highway, a performance feel on winding roads, and reassuring high-performance stopping in emergency situations.

System details include:

  • Anti-lock braking system (ABS) independently modulates braking power at each wheel to help the driver retain steering control during heavy braking.
  • The electro-servo brake system (ESB) uses a motorized electronic actuator to assist braking performance while improving brake feel and pedal modulation in virtually all conditions. ESB continuously analyzes and interprets the driver's brake-pedal inputs and adjusts the braking force to suit.
  • Electronic brake force distribution (EBD) automatically optimizes hydraulic pressure to the front and rear brakes for ideal performance under different vehicle load and driving conditions.
  • Brake assist recognizes emergency braking situations and almost instantly applies full braking force when appropriate.

The 13.0-inch ventilated front brake rotors are 0.4-inch larger than previously, and are clamped by twin-piston calipers. The 13.0-inch rear disc brakes are 0.8-inches larger than previously and incorporate solid rotors paired with single-piston brake calipers. The brake pads are a high-friction type for peak stopping performance even under strenuous conditions. A special brake-pedal yoke spring reduces pedal play for a more satisfying driving experience, while the brake calipers are designed to reduce brake drag when not in use, reducing rolling resistance and improving fuel efficiency in the process.

Case-Hardened Brake Rotors
During manufacturing, the front and rear brake rotors are treated with a high-temperature ferritic nitrocarburizing process (commonly known as case hardening) that infuses the rotors' iron material with nitrogen and carbon to create a more durable working surface. This added step yields high resistance to brake-fade, and scuffing, fatiguing and corrosion during the brake rotors' service life.

Vehicle Stability Assist™ (VSA®) with Traction Control
Vehicle Stability Assist™ (VSA®) is an electronic stability control system that works in conjunction with the TLX's Drive-by-Wire™ throttle and its 4-channel ABS systems to enhance control capability while the vehicle is accelerating, braking, cornering or when the driver makes a sudden maneuver.

VSA® also provides a limited-slip differential effect by applying braking force to a slipping wheel, thereby redirecting driving force to the wheel with more traction. While the driver can reduce the traction control effectiveness allowing more wheel slip during stuck conditions by pressing the VSA® button, ABS remains fully operational at all times.

Agile Handling Assist (AHA)
The TLX's handling dynamics are augmented by Agile Handling Assist, which uses the brakes selectively to improve initial turning response, increase overall cornering ability, and inspire driver confidence. By using brake vectoring – applying braking force independently at each wheel as necessary – during cornering, the system creates a "yaw moment," thus generating more turning force and reducing understeer.

Integrated Dynamics System
The Integrated Dynamics System on the 2021 TLX automatically and seamlessly fine tunes powertrain, chassis and Active Sound Control system functions on a continual, real-time basis to maximize vehicle performance and driver enjoyment and excitement, regardless of conditions.

Systems adjusted via mode selection include:

  • Throttle response
  • Automatic transmission function
  • Active Sound Control (ASC)
  • Electric Power Steering (EPS)
  • Adaptive Damper System (ADS) (Advance Package)
  • Super-Handling All-Wheel-Drive (SH-AWD)
  • Idle stop functionality
  • Interior lighting theme

Using the console-mounted Dynamic Mode Dial, drivers may preset Comfort and Normal as their default mode (enabled upon engine start), while the Sport and Individual modes can be selected after engine start-up. The selected mode is then displayed on the Multi-Information Display located between the tachometer and speedometer.

  • Comfort mode optimizes throttle response, shifting, electric power steering, SH-AWD® rear-wheel torque-vectoring (if TLX is so equipped) for the most luxurious driving experience. This setting makes the TLX relaxed and easy to drive.
  • Normal mode enhances throttle, SH-AWD® rear-wheel torque-vectoring control (SH-AWD® models) EPS and ADS (Advance Package) to sharpen vehicle dynamics. This setting provides direct and sport-tuned response and feel.
  • Sport mode adjusts transmission shift mapping, throttle response, SH-AWD®, EPS, ADS (Advance Package), and Active Sound Control (ASC) to maximize the driver experience.
  • NEW: Individual allows drivers to independently select their desired setting (Comfort, Normal or Sport) for all controlled dynamic systems including powertrain (throttle response, transmission shift mapping, and Active Sound Control (ASC)), steering, SH-AWD®, idle stop, Adaptive Damper System, and interior lighting schemes.

Hill Start Assist
The Hill Start Assist function helps to prevent the vehicle from rolling backwards when the driver switches from the brake pedal to the accelerator pedal while the vehicle is stopped on a hill. Hill Start Assist automatically activates when the vehicle senses a certain incline and is fully stopped in any forward gear when facing up hill or in reverse gear when facing downhill. The system uses a longitudinal G-sensor along with a wheel speed sensor to control the hydraulic brake modulator. When activated, Hill Start Assist will release the brakes when the driver depresses the throttle or if the driver doesn't press the accelerator after a few seconds.

Electric Parking Brake (EPB)
The standard Electric Parking Brake (EPB) is simpler, more convenient and comfortable to use than a traditional parking brake. Engaging the parking brake requires only a pull on a switch on the center console. To release the parking brake, the driver simply presses on the accelerator pedal while the seatbelt is buckled when the transmission is in Drive or Reverse or else pushes on the parking brake switch while operating the brake pedal.

Automatic Brake Hold
When activated, Automatic Brake Hold retains brake pressure when the vehicle comes to a stop such as at a traffic light or in heavy traffic. This frees the driver from continually pressing the brake pedal to maintain the vehicle in a stopped position until the driver presses the throttle pedal.

Weight Distribution
Handling balance is dependent on suspension design and unibody structural stiffness, but it also requires controlling the component weight and packaging to optimize the vehicle's center of gravity. During its redesign, TLX engineers moved the center of gravity 3.4 inches rearward. Contributing to this advancement were an aluminum hood and front fenders, and the repositioning of the absorbed glass-mat (AGM) 12-volt battery (Group 94R with 800 CCA) from its traditional location under the hood to a compartment inside the trunk. The location also helps lower the vehicle's center of gravity and helps keep the battery cool. Positive and negative jump-start terminals are provided under the hood.

Overall, these changes resulted in an improved front/rear weight distribution of 57/43 percent compared to the previous generation TLX's 60/40 percent front/rear weight distribution for models equipped with SH-AWD®. The improvement helps the TLX dynamically in virtually all driving conditions, especially during spirited cornering and emergency avoidance maneuvers.

Wheels and Tires
The new TLX comes standard with 18-inch aluminum alloy wheels. To enhance cornering performance, the TLX with Technology Package, A-Spec Package and Advance Package feature 19-inch aluminum alloy wheels, and each TLX model features its own unique wheel design and finish.

The standard TLX rides on 235/50R18 tires mounted on 18 x 8-inch wheels, while the TLX with Technology Package, A-Spec Package and Advance Package have wider and lower-profile 255/40R19 tires on 19 x 8.5-inch wheels. Specifically designed for TLX, the all-new tires feature updated tread compounds and tire constructions focused on enhanced handling performance while also reducing rolling resistance, and both the 18- and 19-inch tires are 10 mm wider than previously. The standard 18-inch tire offers the same level of lateral grip as the available 19-inch tire from the previous-generation TLX equipped with SH-AWD. Similarly, the performance-tuned 19-inch tires on TLX models equipped with SH-AWD offer a 3.6 percent improvement in lateral grip compared to the 19-inch tires on the previous-generation TLX equipped with SH-AWD.

All 2021 TLX tires carry an M+S all-season rating, making them suitable for year-round use in all weather and road conditions. To maximize trunk volume, all 2021 TLX grades feature an easy-to-use tire repair kit in lieu of a temporary spare.

The TLX with Advance Package also includes a Head-Up Display and Surround View Camera System.

The new TLX has the newest generation of Acura's Advanced Compatibility Engineering™ (ACE™) body structure, high-strength steel front door stiffener rings, and for the first time, eight airbags including next-generation front airbags and driver and new front-passenger knee airbags. Acura engineers also targeted the highest available safety ratings from the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS), including the TOP SAFETY PICK + (TSP+) rating.

Every 2021 TLX is equipped with the AcuraWatch™ suite of driver-assistance technologies, which helps to improve the driver's situational awareness and, in certain circumstances, intervenes to help avoid a collision or mitigate its severity.

Next-Generation Advanced Compatibility Engineering™ (ACE™) Body Structure
The TLX utilizes the latest version of Acura's Advanced Compatibility Engineering™ (ACE™) body-structure to enhance occupant protection and crash compatibility in frontal collisions. The ACE body structure uses a network of interconnected structural elements to absorb and distribute crash energy away from the passenger compartment.

To further enhance occupant protection, the 2021 TLX central floor tunnel is made of high-strength steel and ties into the lower front bulkhead. This advanced structure channels crash loads into and through the tunnel instead of into the passenger cabin. Rear crash load paths are similarly dispersed. (See the Body & Exterior section for more information.)

The enhanced frontal crash energy management can also help to more evenly disperse the forces transferred to other vehicles in a crash. Additionally, ACE helps minimize the potential for under-ride or over-ride situations that can happen during frontal impacts with a larger or smaller vehicle. (See the Body and Exterior section for more information.)

Collision Safety Ratings
In federal National Highway Traffic Safety Administration (NHTSA) testing, the TLX is targeted to achieve a 5-Star Overall Vehicle Score. In Insurance Institute for Highway Safety (IIHS) testing, the TLX is targeted a TOP SAFETY PICK+ rating, including a GOOD rating for all crash modes and a SUPERIOR rating in front crash prevention on all grades.

Crash Energy "Pathways"
Unlike most conventional designs that direct frontal crash energy only to the lower load-bearing structures in the front end, the TLX's latest ACE™ body structure actively channels frontal crash energy to both upper and lower structural elements, including the floor frame rails, side sills and A-pillars. By creating specifically engineered "pathways" that help distribute these frontal impact forces through a greater percentage of the vehicle's total structure, the ACE body structure can more effectively route crash energy around and away from the passenger compartment to help limit cabin deformation and improve occupant protection.

Structural Safety
Meeting the TLX's crash-safety rating targets required advanced structural engineering features, including side collision-load pathways, ultra-high-strength-steel door reinforcement beams, and one-piece outer ultra-high-strength front door rings made of 1500-MPa press hardened steel. These features and more help improve occupant protection. (See the Body and Exterior section for more information.)

Airbag System
The new TLX is equipped with eight airbags, the most ever for the model. These include a driver front airbag, advanced next-generation front passenger airbag, front side airbags, side-curtain airbags with rollover sensor, and both driver and front passenger knee airbags.

Driver Front Airbag
Every TLX is equipped with an advanced front driver's airbag. The front airbag is designed to supplement the seat belts to help reduce the likelihood of head and upper body injuries in frontal crashes.

NEW: Next-Generation Front Passenger Airbag
The 2021 TLX incorporates innovative passenger front airbag technology designed to better protect occupants in a wide range of frontal collision scenarios. The new airbag is particularly beneficial in angled frontal impacts in which lateral collision forces can cause an occupant's head to rotate severely or slide off the airbag, increasing the chance of serious injury.

Unlike conventional airbag systems that rely on a single inflatable compartment, the new system utilizes four major components: three inflated compartments – including a center chamber and two outward-projecting side chambers that create a wide base across the dash – along with an uninflated “sail panel” that stretches between the two side chambers at their outermost edge. Operating something like a baseball catcher's mitt, the sail panel catches and decelerates the occupant's head while also engaging the side chambers, pulling them inward to cradle and protect the head, mitigating the potential for injury resulting from the velocity of head rotation.

Driver and Front Passenger Side Airbags – Driver and front passenger side airbags mounted in the outboard area of each front seatback are designed to help provide pelvis and thorax protection in the event of a severe side impact.

Side Curtain Airbags with Rollover Sensor – All outboard seating positions include a side curtain airbag system. In addition to providing a significant level of head protection in side impacts and rollovers, the side curtain airbags in the 2021 TLX offer enhanced protection in frontal impacts. The side curtain airbags feature optimized cell patterns and sizes designed to work harmoniously with the frontal airbags.

Driver and Passenger Knee Airbags – In addition to the driver knee airbag, the 2021 TLX features a new front passenger knee airbag. The airbags are designed to better control the forward motion of the occupants in the event of a frontal collision, in conjunction with the front airbags and seatbelts. Each knee airbag is contained beneath a panel on the underside of the instrument panel, which is contoured away from the knees.

Three-point seatbelts are standard for all seating positions. New for TLX, both the front and outboard rear seatbelts are equipped with pyrotechnic pre-tensioners and load-limiting retractors to help mitigate injuries in a frontal collision.

Adjustable Head Restraints
All five front and rear seating positions feature individually adjustable head restraints with the TLX's front head restraints featuring the latest generation of neck protection performance. Four-way adjustable front head restraints have four vertical positions at 10-millimeter intervals, as well as adjustment fore and aft.

Child Safety Features
The 2021 TLX features improved usability for its two sets of Lower Anchors and Tethers for CHildren (LATCH) child seat-mounting positions. The LATCH system utilizes both an upper child-seat tether anchor and dedicated lower-anchor points that are built into the body of the vehicle to ensure correct mounting of compatible child seats. A third upper tether mounting position is located in the rear center position. In addition to optimized lower latch and upper tether mounting positions, the lower latch mounting positions feature a removable flap allowing for easy visibility and access, while also substantially reducing the required installation force. These usability enhancements target the highest rating of GOOD+ in IIHS LATCH ease of use testing.

The TLX also features childproof rear door locks. When engaged, they permit the rear doors to be opened only from the outside, thereby helping to prevent accidental opening.

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

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

AcuraWatch™ Active Safety and Driver-Assistive Technology
Standard on all TLX grades, the AcuraWatch™ suite of driver-assistance technologies include the following:

Lane Keep Assist System (LKAS)
Included in all TLX grades, the Lane Keeping Assist System (LKAS) provides a less stressful driving experience by reducing steering correction movements and driving effort on the highway. LKAS uses a camera to read lane markings and uses EPS to assist the driver in keeping in the middle of the lane.

Designed for the U.S. road structure, the system uses a Monocular Camera mounted on the upper portion of the windshield to identify solid or dashed painted lines, Botts' dots and cats eye markers at speeds between 45 mph and 90 mph. When LKAS senses that the driver is drifting from the middle of a detected lane, the system generates corrective steering torque to assist the driver in maintaining lane position.

Collision Mitigation Braking System™ (CMBS™)
Included in all TLX grades, Acura's latest version of its Collision Mitigation Braking System™ (CMBS™) alerts the driver when it determines there is potential for a collision, and then applies automatic emergency braking to help reduce the severity of a collision if drivers don't take corrective action on their own.

When CMBS determines there is a potential for collision, visual and audible alerts prompt the driver to take corrective actions. The visual alerts appear on the Multi-Information Display (MID), and on the Advance Package, additionally on the windshield via the Head-Up Display. If the system determines that a collision is imminent, it applies the brakes to help reduce vehicle speed and eventual collision forces.

A Millimeter Wave Radar unit located behind the front grille and a Monocular Camera mounted at the upper portion of the windshield are used to detect vehicles and pedestrians. This "fusion" of radar and camera allows the system to more effectively detect the nature, distance and speed of obstacles to determine whether there's a potential for a collision.

For 2021, the radar unit has a wider field of view, allowing for improved detection of objects, including pedestrians, which are located further in the vehicle's periphery. In order to accommodate the wider field-of-view, along new U.S. Department of Transportation requirements for protecting the integrity of the radar unit in the event of a frontal collision (FVMSS part 581), engineers moved the radar unit farther back from the front bumper and, therefore, adopted a larger transparent shield, which helps to ensure proper operation of the radar sensor and protects it from the elements.  

It is important to note that CMBS cannot detect all objects ahead, nor is it intended to replace the driver's assessment of traffic conditions and control of the vehicle. The driver must intervene in certain situations and must always be attentive when using the system. Although in many cases CMBS will stop the car, it is not intended to apply enough braking force to prevent all collisions. Based on the conditions, the system also may not perform all visual- and audible-alert stages, and may instead automatically engage the brakes if the system deems it necessary.

Forward Collision Warning (FCW) – Integrated with CMBS™
Included in all TLX grades, Forward Collision Warning (FCW) uses a camera mounted in the upper portion of the windshield to detect vehicles and pedestrians ahead and to determine whether a collision is imminent. If the FCW system detects a vehicle or pedestrian in front of the TLX and then determines that a collision may occur (due to a speed differential between the TLX and the object), it will trigger a "BRAKE" message on the Multi-Information Display (MID) and Head-Up Display (on Advance Package) and an audible alert. If CMBS™ is activated and the driver fails to respond to the FCW system, the vehicle's brakes will be automatically applied if the system determines a collision is imminent.

Drivers may adjust the distance at which FCW alerts occur and may choose between "Long," "Normal," or "Short." Drivers may also select "Off" to disable the FCW system entirely.

Please note that FCW cannot detect all objects ahead; accuracy will vary based on weather, speed and other factors.

Adaptive Cruise Control (ACC) with Low-Speed Follow and Traffic Jam Assist (TJA)
Included on all TLX grades, Adaptive Cruise Control (ACC) allows the driver to set a desired speed and following interval behind a vehicle detected ahead, allowing the use of cruise control in light highway traffic conditions. This significantly reduces the driver stress of driving in traffic. The system uses Millimeter Wave Radar and a Monocular Camera to continually track the distance to the vehicle ahead, and then adjusts the TLX's speed to maintain the driver selected following interval. A short, medium, long, or extra-long interval can be selected. When required, the TLX automatically brakes to maintain the set interval.

Low Speed Follow, using the same Millimeter Wave Radar, Monocular Camera, and VSA® modulator, extends the automatic following capability to stop-and-go traffic situations (down to 0 mph). ACC with Low-Speed Follow functions include the following:

  • A preceding vehicle is detected ­in the lane ahead – Decelerates automatically, if required, and then controls the following interval.
  • The preceding vehicle slows to a stop – Stops automatically and remains stationary.
  • The preceding vehicle accelerates from a stop – Resumes following when the SET or RES switch or accelerator pedal is operated.
  • Another vehicle is detected merging in between the TLX and the preceding vehicle – Automatically switches "targets" to the nearest detected vehicle.
  • The preceding vehicle exits the lane – ACC with low speed follow system continues at cruise-control speed previously selected by driver (25 to 90 mph).

The 2021 TLX now includes Traffic Jam Assist (TJA) for the first time. In conjunction with the Lane Keeping Assist system (operational from approximately 45 mph to 90 mph), TJA operates at speeds below 45 mph to help the driver maintain lane position when traveling at slower speeds, such as might be experienced in congested traffic conditions.

When activated, by a switch on the right side of the steering wheel, TJA will automatically scan for a preceding vehicle and lane markings. The system can help the driver maintain lane position at speeds below 45 mph, with light steering assist all the way to a complete stop if needed.

A Multi-Information Display (MID) and Head-Up Display (Advance Package) message appears and related icons illuminate when ACC, Low-Speed Follow or TJA functions are activated.

Road Departure Mitigation (RDM) with Lane Departure Warning (LDW)
Included in all TLX grades, Road Departure Mitigation (RDM) uses a Monocular Camera (mounted on the upper portion of the windshield) to identify solid or dashed painted lane lines, Botts' dots and cats eye markers. RDM uses both steering force and braking force to help the vehicle stay in its lane.

The Monocular Camera recognizes lane features and identifies the lane. If the RDM system detects that the TLX is about to leave the detected lane, it will provide steering assist (primary) and in rare occasions when steering is not sufficient, braking assist, to help the driver stay on the road. Only lane departure is activated if the driver is passing over a dashed line, Botts' dots or cats eye markings, while deceleration support is disabled. In this case, TLX uses active steering force to return to the lane. RDM is integrated with the electro-servo brake system to provide moderate braking, and with the Electric Power Steering (EPS) system to provide steering input.

When the RDM system detects that the TLX is about to leave the detected lane, it displays a visual Lane Departure Warning (LDW) on the Multi Information Display (MID). If the driver does not respond, the system will produce an audible warning and take corrective action. RDM also has a customizable initial warning of either a steering wheel vibration or an audible alert. This can be customized in the vehicle settings.

New: Traffic Sign Recognition
In a first for Acura, all 2021 TLX grades include a new camera-based Traffic Sign Recognition feature that supports the driver in recognizing traffic speed limit signs. The TLX's monocular camera can automatically recognize speed limit signs and display the information on the Multi-Information Display (MID). The information is displayed immediately after the TLX passes the sign.

New: Driver Attention Monitor
New on the 2021 TLX, the Driver Attention Monitor continually monitors and assesses driver behavior behind the wheel to help determine if the driver is becoming inattentive – if so, warning the driver to take a break. The system uses input from the Electric Power Steering (EPS) to measure both the frequency and severity of the driver's steering inputs to gauge their level of awareness with four gradients.

When the Driver Attention Monitor is activated, the driver is first alerted by a coffee cup icon and a 4-level bar graph that is displayed on the Multi Information Display (MID). The bar graph indicates full attention when four white bar elements are illuminated. As the driver attention drops, fewer and fewer bars are illuminated. When the number of bars drops to two, a message inviting the driver to take a break is illuminated. If the driver continues driving and the graph drops to the lowest level of one bar, a beeper sounds and the steering wheel vibrates, prompting the driver to pay closer attention or take a rest break.

Multi-Angle Rearview Camera
A multi-angle rearview camera is standard on the TLX, TLX with Technology Package and TLX A Spec. It offers three viewing angles (wide view, normal view and top view). Drivers may select the preferred view according to driving conditions. The rearview image is displayed on the 10.2-inch color information display. On-screen guidelines help the driver better judge distances, and predictive guidelines help make maneuvering in reverse easier.

Rear Cross Traffic Monitor
Included in the Technology Package, the Rear Cross Traffic Monitor works in conjunction with the BSI radar sensors to enhance driver confidence when backing up. The system is especially useful when reversing in congested parking lots with an obstructed view from driver's seat.

The system utilizes a pair of blind-spot radar units located in the rear bumper corners. When Reverse is selected and an approaching vehicle is detected, arrows indicating the approaching vehicles direction are shown on the 10.2-inch display's rear camera image. Simultaneously, an audible warning is emitted if cross-traffic is approaching from either side.

Blind Spot Information
The blind Spot Information (BSI) system, included in the Technology Package, uses two radar sensors to continually monitor conditions behind the TLX and alert the driver if another vehicle is detected in close proximity – especially in the blind spot of the driver. The BSI system uses the LED indicators mounted on the A-pillar and an audible warning to alert the driver.

There are two warning levels: 1) If a vehicle is detected in the driver's blind spot then the LED indicator on the incoming side illuminates; and 2) If a vehicle is detected and the TLX turn signal is activated, the LED indicator on the incoming side blinks and a buzzer sounds three times. To prevent false alarms while maneuvering at low speed, the BSI system is disabled below approximately 20 mph.

Parking Sensors
To assist in maneuvering in tight spaces, such as entering or exiting a parking space, the 2021 TLX with Technology Package features a set of eight parking sensors. A sensor is located at each corner of the vehicle with an additional two across the center of the front and rear. When a sensor or sensors detects an object close to the vehicle, the system provides an audible warning plus a visual alert on the MID and, when backing up, also on the 10.2-inch color information display when rearview camera view mode is engaged. With each type of visual alert, the system indicates in what direction the detected object is located.

Surround View Camera System
In the TLX with Advance Package, four exterior cameras provide a 360-degree “bird's eye” view of the space immediately around the vehicle through the 10.2-inch display. A camera button among the upper display controls changes camera views to provide a choice of six different angles.

When Reverse is selected, the rear camera view appears on screen along with an overhead 360-degree view. Guidelines appear in each view, which correspond with the angle of the front wheel's angle to show the vehicle's predicted rearward path. A press of either camera button switches to show the rear view alone, and another press shows a wide-angle rear view.

Pressing either "CAMERA" button when not in reverse shows the 360-degree view combined with a front view that is useful for putting the vehicle in the ideal position in the garage. Another button press provides a front wide-angle view that is useful for helping spot an approaching vehicle or person when nosing out a tight spot with a blocked side view. Additional views include looking ahead from both sides and just the passenger side view alone.
