The 2015 Acura TLX Prototype was unveiled today in Detroit, showcasing the design and performance direction for the all-new 2015 TLX performance-luxury sedan launching mid-year at Acura dealerships nationwide.

Acura’s TLX sedan will replace the current TL and today’s concept is a very mildly disguised version of the production car.

Acura said an all-new 2.4-liter 16-valve inline 4-cylinder engine will be found under the hood which employs direct-injection and Acura’s i-VTEC valvetrain, and is significantly lighter than previous Acura engines of similar configuration and displacement.

The new engine is combined to an all-new 8-speed dual clutch transmission (DCT) with torque converter. This new 8-speed DCT is said by Acura to deliver incredibly quick and smooth gear changes, expertly matching engine revs on down shifts, and putting the power down in a responsive and intuitive way.

The TLX will also offer a version of its well known 3.5-liter SOHC V-6 that employs direct injection and VTEC variable valve control and cam timing along with fuel-saving Variable Cylinder Management (VCM) cylinder deactivation technology. The 3.5-liter V-6 will be combined to a new 9-speed automatic transmission with closely spaced gear ratios and a wide overall ratio range.

Acura stated both the 2.4-liter and 3.5-liter TLX models will target EPA fuel economy ratings at the top of the midsize luxury sedan class.

Acura also said two-wheel-drive models with either the 2.4- or 3.5-liter powerplant will utilize the next generation of Acura Precision All-Wheel Steer (P-AWS) technology with independent left and right rear wheel toe control.

The TLX SH-AWD, available exclusively with the 3.5-liter V6 engine and 9-speed transmission, will employ a new generation of Acura’s signature Super-Handling All Wheel Drive technology that is 25 percent lighter and incorporates new torque-vectoring control logic.

Acura added the TLX will feature an Integrated Dynamics System (IDS) to allow for further personalization and a sportier driving experience. The four driving modes – ECON (Economy), Normal, Sport, and a new Sport+ mode – take full advantage of the TLX’s high-performance capabilities. Depending on which mode the driver selects, the Integrated Dynamics System will adjust Electric Power Steering (EPS), throttle response, SH-AWD and P-AWS control logic, transmission shift mapping, Active Noise Control settings and HVAC control in accordance with the preferences of the driver.

The TLX will utilize Acura’s next-generation Advanced Compatibility Engineering (ACE) body structure and is expected to achieve the highest available safety ratings. The TLX will be available with Acura’s most advanced safety and driver-assistive technologies including Collision Mitigation Braking System (CMBS), Forward Collision Warning (FCW), Lane Departure Warning (LDW), Lane Keeping Assist System (LKAS), Adaptive Cruise Control (ACC) with Low-Speed Follow and Blind Spot Indicator (BSI).

The TLX will be manufactured in the Marysville, Ohio auto plant which presently manufactures the 2014 Acura TL performance-luxury sedan.

As it was unveiling this mild prototype, Acura also pulled the wraps off the new 2015 Acura TLX GT Race Car, announcing plans to move up to the GT category of the Pirelli World Challenge Championship.

Developed from the production 2015 Acura TLX by HPD, the racing arm of American Honda Motor Co., Inc., Acura explained the TLX GT Race Car will feature HPD chassis and aerodynamic performance parts approved for Pirelli World Challenge competition, and will be powered by a direct-injected, twin-turbocharged V6 engine, developed by HPD from the normally aspirated, production TLX luxury sport sedan. It will utilize all-wheel drive, as found in Acura’s Super-Handling All Wheel Drive (SH-AWD).
