You might not have thought of the Mustang as a reasonably fuel-efficient vehicle a number of years ago; but times have changed. The 2014 Ford Mustang can be one of the more economical-to-operate—and dare we say, reasonably green—sporty coupes. If, that is, you can go for the V-6 and manage to restrain your right foot.
V-6 versions of the 2014 Mustang manage up to 31 mpg highway, according to the EPA. Go for the 420-horsepower V-8 and drive it gently and you won't see your fuel budget go out of control either; they're rated at up to 26 mpg highway.
As for the super-performance Shelby GT500, don't expect to do nearly as well; that version is rated at 15/24 mpg—numbers that we think could be highly optimistic, given the constant temptation.
