What does MPGe mean? Electric-car efficiency explained
MPGe stands for miles per gallon of gasoline-equivalent. Because electric vehicles don't burn fuel, the U.S. EPA created MPGe so you can compare an EV's energy efficiency to a gas car on one scale. It is based on the fact that 33.7 kilowatt-hours (kWh) of electricity contains the same energy as one gallon of gasoline.
So a car rated at 100 MPGe travels 100 miles on the energy in one gallon of gas (33.7 kWh). Higher MPGe means less energy used per mile. A typical modern EV is rated around 100–140 MPGe combined — several times more efficient than a comparable gas car (often 25–35 mpg).
MPGe vs range: MPGe measures efficiency, not how far you can drive — that's the battery range. Two EVs can share an MPGe rating but have very different ranges depending on battery size.
