Base TLX models come with a 2.4L 4-cylinder engine that makes 206 horsepower. Power is sent to the front wheels via an 8-speed dual-clutch transmission, which features a torque converter to smooth out any jerkiness in the drivetrain during low speed operation. The optional engine is a 3.5L V6 that makes 290 horsepower. Power is sent to either the front or with Acura's Super Handling-All Wheel Drive (SH-AWD) system, all four wheels via a 9-speed automatic transmission. Acura worked to improve the sports credibility of the TLX with the additions to the A-Spec package. The package comes with a unique suspension and quick ratio steering setup that is paired with the 4-wheel steering system. This allows the TLX to be both nimble and stable when carving up a twisty road.
