The electric Chevrolets, measured differently
Chevrolet has 7 models that never visit a filling station, averaging 102.3 MPGe. That figure looks four times better than the 21.2 mpg the petrol Chevrolets 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 |
|---|---|---|---|
| Chevrolet Bolt EV | 28.3 | $577 | |
| Chevrolet Spark | 28.3 | $577 | |
| Chevrolet Equinox | 31.1 | $634 | |
| Chevrolet Blazer | 33.3 | $679 | |
| Chevrolet SS | 39.6 | $808 | |
