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 is available in numerous configurations including a choice between front-wheel-drive and all-wheel-drive. And for 2010, the TL SH-AWD® is now available with either a Sequential Sportshift 5-speed automatic or an all-new 6-speed manual transmission. However, the special TL 6MT goes well beyond the addition of a new transmission. Acura engineers developed a complete performance package for the 6-speed model that includes numerous enhancements to handling, steering and reliability. Not only is the manual transmission model the best performing Acura TL ever, but it is the top performer in handling amongst every vehicle in its class.
The 2010 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 generation TL's Type-S model is the TL SH-AWD® model that is built exclusively for the enthusiast driver. Featuring Super Handling All-Wheel Drive™, special suspension and steering tuning, the most powerful engine from Acura ever and an all-new close-ratio 6-speed manual gearbox, the 2010 TL offers plenty of appeal for both commuters and performance enthusiasts. Unlike some sedan competitors that add all-wheel-drive to their vehicle to primarily help in winter conditions, the TL's available SH-AWD® was specially 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 2010 Acura TL and TL SH-AWD® are each fitted with a transversely mounted V-6 engine 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 the intake valves actuated by Acura’s VTEC® (Variable Valve Timing and Lift Electronic Control®) system. This compact and efficient engine produces 280 horsepower and 254 lbs-ft of torque.
The 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.
Both V-6 engines reflect Acura’s unwavering commitment to the environment with good fuel efficiency given their power output. All TL engines meet EPA TIER 2 - BIN 5 and CARB LEV II ULEV standards, and have close-coupled catalytic converters to ensure efficient cold-start emissions control.
The standard transmission in the TL is a Sequential SportShift 5-speed automatic transmission with a straight-gate style console-mounted shifter. For more spirited driving, a racing-inspired steering wheel paddle shifter system is standard and works when the transmission is in "Drive" or "Sport".
For 2010, an all-new close ratio 6-speed manual transmission with a new clutch system is available for the TL SH-AWD®. In addition to providing more gear choices (six forward gears versus five) compared to the TL’s Sequential SportShift 5-speed automatic transmission, the new 6-speed manual transmission is approximately 110 lbs lighter in weight to further benefit acceleration, deceleration and handling.
