The Environmental Protection Agency (EPA) records the TSX’s fuel economy by body style and drivetrain. The 2011 Sport Wagon rates highly at 22/30 mpg; the sedan earns ratings of 20/28 mpg for the four-cylinder manual, while the automatic boasts 21/30 mpg.
The V-6 sedan still is rated at a fairly strong 18/27 mpg. It’s an especially good showing, considering the extra 79 horsepower on tap.
Acura offers no hybrid drivetrains with the TSX—or on any of its vehicles. A planned diesel version of the TSX sedan was canceled last year.
