The mid-size Acura TL returns mostly unchanged for 2010. Redesigned in 2009, the car features the bold angular yet sleek styling that Acura is now known for and a roomy interior with a host of high-tech features. On the inside, the TL has a layout that affords both the driver and front passenger their own personal space, divided by a center console and audio controls that protrude outward. Front occupants get firm but comfortable sport seats, and there's space in back for three across. A 280-horsepower, 3.5-liter V6 powers front-wheel-drive versions, through a Sequential SportShift 5-speed automatic transmission. The all-wheel-drive SH-AWD model upgrades to a 305-horsepower, 3.7-liter V6 and a throaty high-flow dual exhaust system that brings more of a sport-sedan character. Although the all-wheel-drive model does improve the TL's available traction in snow and on slippery roads, the primary focus of the so-called SH-AWD (super handling) is to improve stability in sharp corners by sending torque to the wheels that need it most. New this year and available only on the SH-AWD is a 6-speed manual transmission, which is a full 110 pounds lighter than the comparable automatic, and helps make for better handling, stopping, and acceleration. For both models, a double-wishbone front suspension and rear multi-link setup assures a firm but smooth ride. The SH-AWD model is tuned for more responsive handling without giving up much in ride comfort, by incorporating a performance-tuned suspension, larger wheels and tires, and a version of the electric power steering system tuned for more feel of the road. Versions equipped with the 6-speed manual transmission also receive numerous other changes to the vehicle's dynamics, including an all-new self-adjusting clutch assembly and a specially calibrated Hill Start Assist that helps hold the vehicle on inclines of 8 degrees or more. The hood is made of aluminum for weight savings in both models. Standard features on the TL include dual-zone climate control, a power moonroof, leather upholstery, a Bluetooth HandsFreeLink calling interface and an 8-speaker, 276-watt sound system that features XM Satellite Radio and is compatible with Bluetooth audio streaming. Options are limited on the TL, the most noteworthy of them being the Technology Package. It brings premium Milano leather surfaces, plus Acura's voice-recognition navigation system, AcuraLink real-time traffic and weather info, a surround-sound premium system with ten speakers, 440 watts and a 2,500-song hard-drive system, and Keyless Access. An active noise cancellation system and ambient lighting system are also included.
