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 | $0.019 | $188 | $282 | $376 |
| $3.00/gal | $0.023 | $226 | $338 | $451 |
| $3.20/gal | $0.024 | $241 | $361 | $481 |
| $3.50/gal | $0.026 | $263 | $395 | $526 |

| $5.00/gal | $0.038 | $376 | $564 | $752 |
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.
