*MPG when operated on gasoline. † MPGe is miles per gallon of gasoline-equivalent and represents the miles per amount of energy of a non-gasoline fuel that is equivalent to the amount of energy in a gallon of gasoline. For an EV or PHEV, 33.7 kilowatt-hours of electricity represents the same amount of energy as one gallon of gasoline. ‡ The Chevrolet Volt is ranked based on a combined electricity and gasoline value of 60 MPG.
