The TLX is 3.8 inches shorter than the current TL, slotting in between the ILX and the RLX models, but still shares the TL's 109.3-inch wheelbase. This gives the appearance of pushing the wheels out to the corners of the vehicle.
Two engines will be available for the 2015 TLX when it arrives. The first is an all-new 2.4-liter inline four-cylinder engine that uses direct-injection and Acura's signature i-VTEC valvetrain. The automaker tells us that the new engine is significantly lighter than previous mills of similar displacement.
The other engine option will be a 3.5-liter V-6 engine that uses direct-injection and cylinder deactivation technologies to boost its fuel efficiency potential. We've seen a version of this engine under the hood of various Honda and Acura models, so we can guess that it outputs about 310 horsepower and 272 pound-feet of torque, despite Acura omitting specs in the release.
The V-6 is paired with a new nine-speed automatic transmission. With so many gears, Acura is able to use closely spaced ratios for good acceleration, while maintaining a wide overall range for good cruising fuel efficiency.
Front-wheel drive models with either available engine will be able to benefit from Acura's Precision All-Wheel Steer (P-AWS) technology, which allows independent toe steering of the left and right rear wheels and boosting the sedan's responsiveness.
The V-6 engine and its nine-speed automatic are also available with the next generation of the automaker's Super Handling All-Wheel Drive (SH-AWD) system, which is 25 percent lighter than the previous generation, and now employs torque vectoring on the rear axle.
Acura's driver-assistance technology suite will be available on the TLX, including the awesomely weird Lane Keeping Assist System (LKAS) that we tested on the latest MDX. There's also forward-collision warning with collision-mitigation braking, lane-departure warning, adaptive cruise control, and blind spot monitoring.
