Base TLX models come with a 2.4L 4-cylinder engine making 206 hp. 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 making 290 hp. Power is sent to either the front, or with Acura's SH-AWD system, all-four wheels via a 9-speed automatic transmission. Acura worked to improve the sports credibility of the TLX with the addition of the A-Spec package with a unique suspension and quick ratio steering setup paired with the 4-wheel steering system allowing the TLX to be both nimble and stable when carving up a twisty road. Acura offers a choice of 4-cylinder or V6 engines and front-wheel or SH-AWD all-wheel drive, each of which can each be ordered with a Technology Package or Advanced Package. A-Spec is available with both V6 and Technology Package boxes checked. Standard equipment levels are excellent. The base TLX comes equipped with LED headlights, Bluetooth connectivity, SiriusXM satellite radio, a rearview camera, keyless access, a multi-function display, Siri eyes free functionality and USB and iPod connectivity. Buyers who opt for the Technology Package get a navigation system with real-time traffic updates, a premium audio system with HD radio, a colored display screen, a perforated leather trimmed interior, rain sensing wipers, lane assist and lane departure warning systems as well as blind spot and forward collision warning systems. The all-new A-Spec package utilizing a quicker steering ratio, sporty suspension, and lower profile tires demonstrates excellent handling ability without compromise of comfort. The A-Spec is available with black or red Alcantara leather interior with contrasting stitching, exclusive Still Night Blue Pearl exterior paint, Shark Gray 19-inch wheels and unique round LED fog lamps. The V6-powered TLX comes in both front and all-wheel drive configurations, though all-wheel drive versions always come equipped with either the Technology or the Advanced Package. Safety systems across the TLX line include anti-lock brakes, traction control and stability control. Front, side, side curtain and driver's knee airbags are all standard.
