72 MPGe The 2020 BYD e6 is EPA-rated at 72 MPGe combined (73 city / 71 highway). Over 15,000 miles a year that is about 208 gallons, $667 a year in fuel, or $0.044 per mile at $3.20/gal.
Across its full 2012–2020 run it averages 68 MPGe, improving by 10 MPGe over 7 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 | $0.035 | $347 | $521 | $694 |
| $3.00/gal | $0.042 | $417 | $625 | $833 |
| $3.20/gal | $0.044 | $444 | $667 | $889 |
| $3.50/gal | $0.049 | $486 | $729 | $972 |

| $5.00/gal | $0.069 | $694 | $1042 | $1389 |
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.
