The official U.S. Environmental Protection Agency (EPA) range is . Under its five-cycle testing, the EPA rated the 500e combined fuel economy at 116 miles per gallon gasoline equivalent (MPGe) ( equivalent) overall, 122 MPGe ( equivalent) in city driving and 108 MPGe ( equivalent) on the highway. Regenerative braking is employed to extend range; under normal braking (i.e., excluding panic and emergency stops), the brake pedal engages only regenerative braking down to speeds of , when the conventional mechanical brakes begin to engage.
