What it costs to fuel
Across its configurations, the 2017 i3 costs about $600 to $2,300 a year to fuel at the EPA's 15,000-mile basis, averaging roughly $1,183. Over five years that is about $5,917 in fuel alone before maintenance, insurance and depreciation — which is why the running cost, not just the price, decides what a car really costs.
Relative to an average new vehicle, the most efficient i3 configuration saves about $8,500 in fuel over five years; less efficient versions spend more.
For context, the average combined economy of subcompact cars in this dataset is about 27 MPGe. The i3 sits roughly 52 MPGe above that mark at its midpoint, making it more efficient than average for its EPA class.
