Acura TL SH-AWD
From Acura press: With athletic and emotional styling, powerful engine performance and a Super Handling All-Wheel Drive™ (SH-AWD®) model, the fourth-generation 2010 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. After a complete from-the-wheels-up redesign for 2009, Acura aimed to enhance 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), Electric Power Steering (EPS), and a luxurious and technologically advanced interior, the 2010 TL sets the benchmark for the future direction of the Acura division.
The 2010 TL SH-AWD® makes advances 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 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 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 TL SH-AWD® is a top performer amongst every vehicle in its class.
he TL SH-AWD® is powered by a 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. Similar to the 3.7-liter engine that powers the 2010 RL, the TL SH-AWD® engine features a VTEC® system which varies the exhaust valves as well as the intakes to contribute to elevated power output. The 3.7L engine is even lighter than the 3.5-liter engine, due in part to the use of aluminum rather than iron cylinder liners.
The 3.7-liter engine in the TL SH-AWD® is an enhanced version of the powerplant in the 2010 Acura RL, and it is the most powerful engine ever fitted to an Acura sedan. While dimensionally similar to the compact 3.5-liter TL engine, the 3.7-liter employs aluminum (rather than iron) cylinder liners for weight savings and improved cooling. Its VTEC® rocker arm system features variable lift and timing for both intake and exhaust valves. A free breathing intake system, a high compression ratio, a high-flow exhaust system using close-coupled catalytic converters and dual exhaust pipes with four exits all team make the TL SH-AWD® engine the most powerful engine that Acura has ever offered.
