2010 Acura TSX V-6 model year, the front-wheel-drive TSX sedan will be available with a 280-horsepower 3.5L V6 engine. The2010 Acura TSX V-6 offered solely with a naturally aspirated 2.4-liter four-cylinder, I was, in all honesty, a bit let down. Not because I dislike that engine - 201 horsepower, 172 pound-feet, and an F1 personality mixed with redline refinement are hard to fault -- but rather because the TSX's sporty, well-sorted chassis seemed capable of shouldering plenty more oomph.
