SANTA MONICA, California — Information about the 2009 Acura TL leaked out today, revealing full details of the fourth-generation sedan from Honda's premium division. Two different models of the TL will be available: a front-wheel-drive TL with a 280-horsepower 3.5-liter V6 and the all-wheel-drive TL SH-AWD with a 305-hp 3.7-liter V6.

The 2009 Acura TL moves further upmarket with a more aggressive interpretation of Acura's latest styling vocabulary, known as "Keen Edge Dynamic." The size of the car has increased slightly as a consequence, and the wheelbase has been stretched 1.4 inches to 109.3 inches. The car is also 6.2 inches longer overall, 1.8 inches wider and 0.5 inch taller. Rear legroom improves by 1.3 inches and rear shoulder room increases by 0.5 inch. The all-new package also improves structural rigidity significantly, thanks in part to the use of high-strength steel in 47.6 percent of the chassis.

The standard TL will be front-wheel drive and is powered by a 3.5-liter V6 that makes 280 hp and 254 pound-feet of torque, an increase of 22 hp and 21 lb-ft over the previous 3.2-liter V6. The new TL SH-AWD ("Super-Handling All-Wheel Drive" replaces the previous TL Type-S and is powered by a 3.7-liter V6 that produces 305 hp and 275 lbs-ft, an increase of 19 hp and 19 lb-ft over the 3.5-liter V6 of the Type-S. A five-speed automatic transmission is standard equipment for both engines and features shift paddles on the steering wheel.

The chassis features double-wishbone front suspension and multilink rear suspension. Electric power steering is standard for both models. The TL rides on 245/50R17 tires, the TL SH-AWD has 245/45R18 tires and 245/40ZR19 summer performance tires are optional for the TL SH-AWD.

As before, the 2009 Acura TL continues to provide an extensive list of electronic convenience items, now including a central multifunction display, an eight-speaker audio system with a six-disc CD changer, XM Satellite Radio and USB port connectivity. An Acura/ELS audio system with 10 speakers, surround-sound and DVD-A compatibility is available.

What this means to you: The 2009 Acura TL looks more aggressive and backs it up with more power and all-wheel drive, but we'll see if more personality can counter Acura's slow sales decline in recent years. — Michael Jordan, Executive Editor
