The US Energy Department (DOE) on Monday proposed reducing electric vehicles’ (EV) mileage ratings to meet government fuel economy requirements, a move that could force automakers to sell more low-emissions cars or improve conventional models.
DOE wants to significantly revise how it calculates the petroleum-equivalent fuel economy rating for electric and plug-in electric hybrids for use in the National Highway Traffic Safety Administration’s (NHTSA) Corporate Average Fuel Economy (CAFE) program.
The current system has not been updated in more than two decades.
