While there officially was no Mitsubishi i-MiEV for the 2015 model year, that’s because dealers still had a sufficient supply of leftover 2014 units to sell. Sure, the egg-shaped i-MiEV is tiny and slow, but it’s one of the cheapest ways to own a zero-emissions vehicle. It’s EPA-rated at a frugal 126/99 (city/highway) mpg-e, but with an average 62 miles on a charge, it’s the shortest-range model on our list. A 2014 version can be found selling at retail for just $5,325 with average miles. By comparison, a new i-MiEV in 2017 (its most recent model year) started at $23,845.
