MPG vs MPGe : What is MPGe? How is MPGe Calculated?


There have been lots of changes happening in the automotive industry. Brands are always competing to create the best possible vehicles for their consumers. Electric vehicles are a new category for competition and with the increasing number of charging stations nationwide this new transportation option is not going anywhere.
Buyers now need to learn about this new option. The first question usually asked is “What is the mileage on an EV?”. Consider this a crash course made purposely to help buyers like you make the best choice for your routine, family, budget, and lifestyle.

What is MPGe? How is MPGe Calculated?

When looking into Hybrids, Plug-in Hybrids, and fully Electric Vehicles you will undoubtedly come across the new term MPGe. MPGe is an acronym for “Miles Per Gallon equivalent”. MPG stands for “Miles Per Gallon” and tells you how far a particular vehicle can travel using one gallon of gasoline. MPGe similarly tells you how many miles an electrical vehicle can travel using the electric equivalent of one gallon of gasoline.

You can’t simply pour electricity into a bucket to measure one gallon like you can with gasoline, so how do we know the electric equivalent? The Environmental Protection Agency has set the standard electricity to gasoline equivalent for the automotive industry. By measuring the amount of heat produced by one gallon of gasoline after ignition the EPA found a measurement that could be applied to electricity. Following ignition, one gallon of gasoline will produce 115,000 British Thermal Units of heat. In order to get an identical thermal energy output from an electric engine, 33.7 kilowatt-hours of electricity would have to be expended.
