EPA Certified: 2011 Mustang GT Touts 412 Horsepower, 26 MPG Highway

Fresh off the heels of announcing its 2011 Mustang V-6 as the first production vehicle ever to achieve over 30 mpg highway with a 300-plus-horsepower engine, Ford has released newly certified fuel economy details for its 2011 Mustang GT. How does 26 mpg highway from a 412-horsepower 5.0-liter V-8 sound? Yeah, we thought so, too.

Officially, Ford's best-in-class fuel ratings for the GT come out to 17 mpg city/26 mpg highway with a six-speed manual on board. Opt for the six-speed auto and the fuel ratings end up at 18 mpg city/25 mpg highway.

Like its smaller 3.7-liter V-6 cousin (in which we recently rode), the bigger eight-cylinder is built entirely from aluminum and gets the brand's Twin Independent Variable Camshaft Timing (Ti-VCT), tuned intake/ exhaust systems, and revised gear ratios. Ford says the new rear axle ratios (3.31 for the manual, 3.15 for the automatic) are ideal for both cruising and all-out acceleration runs.

Engineers also installed a restyled front clip, taller air damn, rear tire spats, new underbody cladding, and rear decklid seal to provide a more aerodynamic form. A new electronic power steering assembly replaces the engine-operated hydraulic power steering pump and cuts its drag from the GT's efficiency equation.

Here are both the 2011 Mustang V-6's and 2011 Mustang GT's official EPA fuel economy ratings:

Mustang V-6 19 mpg city and 31 highway (automatic), 18 mpg city and 29 highway (manual)

Mustang GT 18 mpg city and 25 highway (automatic), 17 mpg city and 26 highway (manual)
