Acura's new V6-powered version of its TSX sports sedan is finally ready to go sale as part of the updated 2010 lineup. Unveiled at last February's Chicago Auto Show, 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 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.
The 2.4L four-cylinder version remains on sale. The four-cylinder engine, which produces 201hp and 172lb-ft of torque, 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.
Since all 2010 Acura TSX models are endowed with a cutting-edge double wishbone front and multilink rear suspension system, they all boast of being able to provide outstanding control, ride and handling. Likewise, all 2010 TSX models are installed with the revised EPS programming for a sharper steering response and enhanced "on center" feel.
Moreover, the independent front suspension of the Acura TSX V-6 model features firmer springs as well as revised calibration for the dual-mode suspension dampers – thereby providing a new level of sporty handling that matches the performance of the six-cylinder TSX.
Wrapping the standard with 17 x 7.5-inch five-spoke aluminum wheels are Michelin Pilot HX MXM4 P225/50R17 all-season tires developed specially for the 2010 Acura TSX. Meanwhile, the TSX V-6 model will feature an 18 x 8-inch split five-spoke aluminum wheels wrapped in Michelin Pilot HX MXM4 P235/45R18 all-season tires.
All TSX wheels feature a clear-coat aluminum finish that should complement the available exterior color paints. In charge of putting the TSX V-6 model into a performance stop are special rear brake pads, supported by a larger brake master cylinder, a revised pedal ratio and a new brake booster.
On the other hand, all TSX models are underpinned by a chassis that has inside frame rails and a closed-channel cross-braced roof structure, which, along with a stronger rear bulkhead, allows for a stronger and vibration-resistant structure for the 2010 Acura TSX.
Moreover, the inside frame rails help alter the aerodynamics underneath the Acura TSX, thereby increasing its fuel efficiency and reducing emissions and noise. Also helping the TSX stay quiet during speed driving or while traversing rough roads are new A-, B- and C-pillar separators.
Furthermore, the TSX V-6 model employs Acura's Electronic Control Mount system for the engine and transmission, helping manage the NVH levels generated by the vehicle's drivetrain.
While the 2010 TSX still features the sharp and aggressive design of the original TSX, it has a wider body and more muscular cues. There is no major visual difference between the TSX V-6 looks and the four-cylinder TSX aside from the V-6 badge on the trunk and a subtly modified front fascia featuring functional side openings for enhanced radiator cooling.
