After slow intial sales and plenty of unpleasant prods from the media and politicians (revealed in more detail via our ultimate guide), the Volt is finally finding its feet and sales are steadily creeping up. Rather than a typical power-split plug-in hybrid like some of the others here, the Volt is really a range-extended electric vehicle--an electric drivetrain with around 40 miles of range does most of the work, but once you run out of battery juice the 1.4-liter gasoline engine keeps you going.

It's proving an incredibly popular vehicle with owners, who collectively have traveled 63 percent of their miles in EV mode--so Chevy can lay fair claim to the "electric car" tag, despite that internal combustion engine sitting in the nose.
