2017 Toyota Prius Prime Gallery

As efficiency targets go, 120 MPGe is an ambitious one, but that's the challenge Toyota is biting off with the Prius Prime. Latest in the company's revamped plug-in hybrid series, the new hatchback offers twice the all-electric range of its predecessor, with the promise of 22 miles of driving without the engine kicking in.

On the outside, the inspiration of the Mirai fuel-cell car is clear, while inside a new portrait-orientation touchscreen dominates the dashboard. You can't ignore the Tesla feel to that, though the Model S is no longer the only car with such a center console, so let's be generous and call the Prius Prime "inspired by" rather than an outright copy.
