Mitsubishi i-MiEV
112 MPGe The 2017 Mitsubishi i-MiEV is EPA-rated at 112 MPGe combined (121 city / 102 highway). Over 15,000 miles a year that is about 134 gallons, $429 a year in fuel, or $0.029 per mile at $3.20/gal.
Across its full 2012–2017 run it averages 112 MPGe, essentially flat across 5 model years.
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 | $0.022 | $223 | $335 | $446 |
| $3.00/gal | $0.027 | $268 | $402 | $536 |
| $3.20/gal | $0.029 | $286 | $429 | $571 |
| $3.50/gal | $0.031 | $313 | $469 | $625 |
| $4.00/gal | $0.036 | $357 | $536 | $714 |
| $4.50/gal | $0.040 | $402 | $603 | $804 |
| $5.00/gal | $0.045 | $446 | $670 | $893 |
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.
