MPGe is the abbreviation for “miles per gallon of gasoline-equivalent.” It’s an
energy efficiency metric that was introduced by the Environmental Protection Agency (EPA) in 2010 to compare the amount of energy consumed by alternative fuel vehicles to that of traditional gas-powered cars. If a vehicle uses non-liquid fuels that aren’t burned and gets its power from electricity or compressed natural gas, it’s rated in MPGe. This is the calculation you will see on an electric car’s window sticker.
