3. Toyota Prius Plug-In Hybrid — $30,815
The Toyota Prius Plug-In Hybrid is the cheapest plug-in hybrid vehicle on the market. If you’re not sure what that means, here’s how it works: While the Nissan Leaf, Ford Focus Electric and others are fully electric vehicles, the Prius Plug-In offers a range-extending gasoline engine in addition to its electric motor. The downside is that the Prius Plug-In can only travel 11 miles before running out of juice. But the benefit is that you’ll never have range anxiety, since there’s a gasoline engine waiting to pick up right where the EV motor leaves off.
