In model year 2023, the highest-rated EPA combined fuel economy for gasoline vehicles was about 60 miles per gallon (MPG), while two electric vehicle (EV) models – the Hyundai Ioniq 6 and the Lucid Air – achieved 140 mpg-equivalent (MPGe). MPGe is a unit of measure used by the EPA to represent EV fuel economy in a common unit with gas-powered vehicles, where 33.7 kilowatt-hours of electricity are equal to the energy contained in one gallon of gasoline. From MY 2011 (the year modern mass marketed EVs were introduced) to MY 2023, maximum EV fuel economy has grown 37% while gasoline vehicle fuel economy has increased just 19%.
Note: Combined fuel economy refers to EPA’s combined city/highway fuel economy rating. Read more about that rating here.
