All three Acura sedans are revised for 2009.
The entry Acura TSX is a larger, second-generation model with updated exterior styling and a 2.4-liter, four-cylinder engine with 8 more foot-pounds of torque — to 172 foot-pounds — than its predecessor. Horsepower peaks at 201.

The mid-range TL is a larger, fourth-generation model and has the most powerful sedan engine in Acura’s lineup: a 305-horsepower, 3.7-liter V-6 with 273 foot-pounds of torque. This powerplant is available in the uplevel TL SH-AWD version that, for the first time, includes Acura’s special all-wheel-drive system. That not only shifts power from front to rear wheels when needed, but also from one side of an axle to the other for improved cornering.

Acura’s flagship sedan, the RL, has more aggressive styling this year and a more powerful engine: a 300-horsepower, 3.7-liter V-6 that develops 271 foot-pounds of torque. The new RL has a roomier back seat than its predecessor did, and suspension and tires are upgraded.
