The electric Mitsubishis, measured differently
Mitsubishi has 1 model that never visit a filling station, averaging 112 MPGe. That figure looks four times better than the 23.2 mpg the petrol Mitsubishis manage, but the two are not the same unit — so we keep them apart and price the electric ones in kilowatt-hours.
| Model | MPGe | kWh / 100 mi | Charging per year |
|---|---|---|---|
| Mitsubishi i-MiEV | 30.1 | $614 |
