2015 Acura TLX: What's New, Specs & Features
Last updated August 4, 2026
The 2015 Acura TLX is an all-new sedan that replaced both the TL and TSX. Its headline change is a clean-sheet design with a new platform, new engines, and new transmissions.
About the 2015 Acura TLX
1st generation TLX (2015-2020), first model year; all-new replacement for the Acura TL and TSX.
Acura positioned the TLX as a sport-luxury sedan that mixes quick responses with a polished cabin. Acura’s own theme was “Red Carpet Athlete,” meaning the car was meant to feel more engaging than a soft luxury sedan while still delivering the quiet ride, premium materials, and everyday usability buyers expected in this class. Its main appeal was offering several distinct powertrain and equipment personalities within one midsize luxury sedan range.
Acura positioned the TLX as its main midsize sport-luxury sedan, balancing a quiet, comfortable ride with responsive handling. The 2.4 pairs a 206-hp four-cylinder engine with front-wheel drive, while 3.5 versions bring a 290-hp V6 and upscale features such as navigation, leather seating, premium audio, and added driver aids. Every TLX has Jewel Eye LED headlights and a dual-screen dashboard interface.
