Acura teased us back at February’s Chicago Auto Show with a new V6-powered version of its TSX sports sedan, and now the car is finally ready to go sale as part of the automaker’s updated 2010 lineup. The midsize sedan picks up Acura’s familiar 3.5L V6 from its TL and RL siblings, which in the TSX is rated at 280hp (209kW).

To handle the extra power, the car has also been updated with stiffer suspension and new control setting for Acura's Sequential SportShift 5-speed automatic transmission with F1-style paddle shifters. The V6 TSX also sports unique five-spoke 18in aluminum wheels shod with Michelin Pilot all-season tires.

In addition to larger wheels, the V6 TSX is further distinguished from the four-cylinder variant with the use of a slightly revised front fascia and V6 badging. The 3.5L engine meets California's CARB LEV II ULEV emissions certification and delivers an EPA estimated city/highway fuel economy of 18/27mpg.

Remaining on sale is the 2.4L four-cylinder version. Producing 201hp and 172lb-ft of torque, the four-cylinder engine comes standard with a 6-speed manual or optional 5-speed automatic.

All 2010 TSX models feature a double wishbone front and multilink rear suspension system, while the new V6 model's independent front suspension receives firmer springs and revised calibration for the dual-mode suspension dampers.

Like all Acura models, the new TSX features as standard a power moonroof, automatic climate control, a premium seven-speaker sound system with XM Satellite Radio, Bluetooth hands-free and USB and auxiliary ports. Optional goodies include Acura’s Technology Package, which adds satellite navigation, a reversing camera, and a premium sound system.
