From Acura press: With athletic and emotional styling, powerful engine performance and a new Super Handling All-Wheel Drive™ (SH-AWD®) model, the all-new fourth-generation 2009 TL is nothing less than the most exciting performance luxury sedan in Acura history.
Moreover, as the sales volume leader for the division, the TL is also Acura's most important car. In completely redesigning the TL from the wheels up, Acura aimed to enhance literally every aspect of the original model. Featuring a stiff unit-body construction with expansive use of high-strength steel (as well as key aluminum components), unique and dramatic exterior styling, a choice of two powerful VTEC V-6 powertrains (280-hp 3.5L and 305-hp 3.7L), all-new Electric Power Steering (EPS), and a luxurious and technologically advanced interior, the new TL sets the benchmark for the future direction of the Acura division.
For the first time ever in an Acura vehicle, the 2009 TL is available in a choice of front-wheel-drive TL or all-wheel-drive TL SH-AWD® configurations. The new TL is a powerful and precise performance luxury sedan that is as confident and composed on a mountain road as it is in the city center. Replacing the previous TL Type-S is the TL SH-AWD® model, built exclusively for the enthusiast driver and featuring Super Handling All-Wheel Drive™, special suspension and steering tuning, and the most powerful engine from Acura ever. Unlike some competitors, who add all-wheel drive to their vehicles primarily to help in winter conditions, the TL's available SH-AWD® was designed to dramatically enhance sporty handling in addition to further enhancing the vehicle's winter-driving capability. This means that the TL SH-AWD® is inspiring to drive year-round.
The 2009 TL SH-AWD® makes a significant advance in both on-road performance and driving exhilaration as it significantly surpasses the previous track-tuned TL Type-S in all measurable levels of handling performance. Moreover, not only is the new TL SH-AWD® more exhilarating when pushed on challenging roads, but in day-to-day use it delivers a more rewarding and exhilarating level of driving excitement. Without a doubt, the first ever application of SH-AWD® with the TL sedan-Acura's best selling sedan-marks a new milestone for performance, drivetrain sophistication, and safety. Not only is it the best performing Acura TL ever, but the new TL SH-AWD® is a top performer amongst every vehicle in its class.
The 2009 Acura TL and TL SH-AWD® are each fitted with a transversely mounted V-6 powertrain that has been painstakingly engineered to meet the specific requirements of each TL model. The TL features an all-aluminum 3.5-liter V-6 with single overhead camshaft cylinder heads and 24 valves, with all intake valves actuated by the Acura VTEC® (Variable Valve Timing and Lift Electronic Control®) system. This compact and efficient engine produces 280 horsepower and 254 lbs-ft of torque. Compared to the previous generation TL's 3.2-liter engine, the 3.5-liter V-6 delivers 22 additional horsepower and 21 additional lbs-ft of torque.
The TL SH-AWD® is powered by a new 3.7-liter V-6 that shares many features with the 3.5-liter engine, but gains displacement through larger cylinder bores and increased stroke. With 305 horsepower and 273 lbs-ft of torque, the 3.7-liter engine is as powerful as some V-8s, and is the most powerful engine ever offered in an Acura. Compared to the previous generation TL Type-S 3.5-liter engine, the 2009 TL's 3.7-liter V-6 has gained 19 horsepower and 17 lbs-ft of torque. Similar to the 3.7-liter engine that now powers the 2009 RL sedan, the new TL SH-AWD® engine features a new VTEC® system which varies the exhaust valves as well as the intakes to contribute to elevated power output. The engine is even lighter than the 3.5-liter powerplant it replaces, due in part to the use of aluminum rather than iron cylinder liners.
