The electric Rolls-Royces, measured differently
Rolls-Royce has 1 model that never visit a filling station, averaging 78.3 MPGe. That figure looks four times better than the 12.3 mpg the petrol Rolls-Royces 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 |
|---|---|---|---|
| Rolls-Royce Spectre | 43 | $877 |
