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. Acura offers a choice of 4-cylinder or V6 engines and front-wheel drive or SH-AWD, each of which can be ordered with a Technology Package or Advance 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 system, lane departure warning system and blind spot and forward collision warning systems as well. The A-Spec package utilizes a quicker steering ratio, sporty suspension and lower profile tires. It demonstrates excellent handling ability without any major compromises in the comfort department. 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 Advance Package. Safety systems across the TLX line include anti-lock brakes, traction control and stability control. Front, side, side curtain and driver's knee air bags are all standard.
