The electric Jeeps, measured differently
Jeep has 1 model that never visit a filling station, averaging 94.3 MPGe. That figure looks four times better than the 19.1 mpg the petrol Jeeps 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 |
|---|---|---|---|
| Jeep Wagoneer S | 35.7 | $728 |
