Acura has added V6 power to the compact TSX sports sedan for 2010, with the introduction of the 280-horsepower TSX V6.

Many enthusiasts felt that Acura's nimble, cutting-edge TSX would be a serious contender in the sport-luxury market, if only it had enough power and a couple of extra cylinders to compete with the likes of the Audi A4, Lexus IS350 and Infiniti G. It appears that Acura has come to the same conclusion, as it unveiled the latest addition to the lineup, the TSX V6, at the Chicago Auto Show today.

The update is a simple one: Acura has shoehorned a 3.5 liter V6 engine under the hood. The 280-horse powerplant features a dual-stage induction system and VTEC valve control, of course. Acura's sequential SportShift transmission handles shifting duties, and includes paddle shifters, Grade Logic Control and Shift Hold Control for spirited driving.
Exclusive suspension tuning is also part of the mix; the TSX V6 gets unique 18-inch split five-spoke wheels and tires and a tauter suspension, to handle the additional power. Double wishbones are used up front, with five-link construction at the rear.

Apart from the mechanical changes and a slight design change on the front fascia, the TSX V6 is the same as the four-cylinder version. A laundry list of standard equipment includes a power moonroof, automatic climate control, XM satellite radio with Bluetooth connectivity and a USB port and a seven-speaker sound system. The optional Technology Package adds voice-commanded satellite navigation and an upgraded sound system.

The TSX V6 goes on sale this summer as a 2010 model. Acura says this car is the first in a series of upcoming introductions from the brand that will result in "significant enhancements" to every model in the lineup.
