The 2012 Acura TSX does a good job in straddling several purposes, ranging from sensible family commuter to sport sedan; and considering its broad focus, it's a reasonably green choice.The Environmental Protection Agency (EPA) rates the TSX Wagon at 22 mpg in the city and 30 mpg on the highway; the sedan earns ratings of 21/29 mpg for the four-cylinder manual, while the automatic boasts 21/31 mpg.
Go for the V-6, and you won't end up paying much more for gas sedan still is rated at a fairly strong 22/30 mpg. It’s an especially good showing, considering the extra 79 horsepower on tap.
And that leads us back to the four. While we've seen better real-world numbers with the four than with the V-6, it's worth pointing out that a wide range of (larger) mid-size sedans now get better ratings than the TSX--so some shoppers might be a bit disappointed. The diesel version of the TSX that had been in the works was canceled, and there's no hybrid option.
