No two ways around it, the revamped 2009 Acura TSX is a larger, heavier car than the version it replaces. Sure, the suspension wizards tinkered around with anti-roll bars, increased the track width, fitted some trick new dual-mode dampers, and shifted the roll center to keep the new TSX feeling as composed as its lighter, nimbler forbearer. Even the drivetrain techies got involved, bumping the 2.4L four-banger’s compression ratio, improving its breathing for a small increase in torque (8 lb-ft to 172), and shortening the gear ratios in the manual-equipped car to prevent acceleration times from slipping.

The most obvious alternative to putting a car on a diet is to add more power, and that’s precisely what Acura has done with its 2010 Acura TSX V-6. Honda’s premium automaker has stuffed a 280-hp, 3.5L V-6 into the engine bay of the TSX to mute any cries that the European Accord-based sedan has lost some of its soul. Essentially the same VTEC-enhanced engine found in Acura’s base-level TL midsize sedan, the TSX also helps to bridge the gap between TSX and TL in the model lineup. The TSX V-6 will be offered exclusively with Acura’s Sequential SportShift automatic, meaning steering-wheel-mounted paddle shifters will have to quench enthusiasts’ yearnings for a manual gearbox—at least for now.
With the new V-6 comes a retuned suspension. The basic TSX configuration remains—double wishbones up front and a multilink rear setup—but the V-6 variant will receive exclusive specifications aimed at providing a sportier experience than the standard TSX. Additionally, 18-in., split five-spoke aluminum alloy wheels wrapped in Michelin Pilot all-season tires, will distinguish the TSX V-6 model from the four-cylinder variant, as well as providing sharper turn-in and crisper handling. Other than the rolling stock and a V-6 badge, the exterior will be identical to that of its sibling.
