Interesting Details
8-Speed DCT With Torque Converter
Acura described the 2.4L TLX transmission as the world’s first dual-clutch transmission of its type to be paired with a torque converter, combining DCT shift behavior with smoother low-speed operation and torque multiplication at launch.
FWD With Rear Steering
The TLX 2.4 was front-wheel drive, but it also used Acura Precision All-Wheel Steer. The system allowed the rear wheels to adjust toe angle to support low-speed maneuvering, stability, and handling response.

Where This Fits In
Acura TLX 2.4 (UB1)
The Acura TLX 2.4 does not belong to a clean performance lineage in the same way as an NSX, Integra Type R, or BMW M3. Its role is more transitional: it consolidated Acura’s TSX and TL sedan lines into one model and paired a naturally aspirated 2.4-liter i-VTEC inline-four with an 8-speed dual-clutch transmission, front-wheel drive, and Precision All-Wheel Steer.
Model Context
Where The TLX 2.4 Fits
The TLX 2.4 is best viewed as the successor context for Acura’s smaller TSX and part of the replacement strategy for the larger TL. It carried forward the idea of a precise, naturally aspirated Acura sport sedan, but moved away from manual-transmission, enthusiast-focused positioning toward a more refined entry-luxury sedan formula.
