Although there are some similarities, these two are different in most aspects such as model year, body structure, starting price, fuel economy, and ground shadow size. First of all, there is a notable difference in the starting price of the 2013 Nissan Leaf, which is $3,150 less than the base MSRP of the 2016 Kia Soul EV, which is three model years newer. Also, body structures are completely different. One is a Wagon and the other a Hatchback. The 2016 Soul EV is also slightly smaller than the 2013 Leaf. And finally, you get 10 more mpg with the Soul EV than with the Leaf. Among similarities are the market segment and maximum occupancy.
