Running cost at different fuel prices and mileages
The figure everyone actually wants, and the one the EPA does not publish — because it depends on a fuel price no agency will commit to.
| Fuel price | Per mile | 10,000 mi/yr | 15,000 mi/yr | 20,000 mi/yr |
|---|---|---|---|---|
| $2.50/gal | $0.023 | $231 | $347 | $463 |
| $3.00/gal | $0.028 | $278 | $417 | $556 |
| $3.20/gal | $0.030 | $296 | $444 | $593 |

| $5.00/gal | $0.046 | $463 | $694 | $926 |
This is an electric vehicle, so the EPA rates it in MPGe — the distance it travels on the energy equivalent of a gallon of petrol. The dollar figures above are a petrol-equivalent illustration only; charging at home is billed per kWh and is normally far cheaper. Treat the MPGe as an efficiency comparison, not a fuel bill.
