2010 Acura TSX V 6

Unveiled at the Chicago Auto Show, the most powerful version of the Acura's premium sports sedan is fitted with a 280-horsepower 3.5-liter V6 that's coupled to a Sequential SportShift automatic transmission with steering-wheel mounted F1-style paddle shifters. And no, Acura did not equip the TSX V6 with its four-wheel-drive system as it retains the 4-cylinder model's front-wheel drive layout.

The V6 powertrain also brought along a sportier suspension tuning along with 18-inch, five-spoke aluminum wheels, fit with Michelin Pilot all-season tires. To distingush it from the 4-cylinder variant, Acura slightly revised the TXS's front fascia and added a V6 badge on the trunk.
