The U.S. Department of Energy has finalized new rules to estimate the mileage of electric vehicles. The ruling better represents the real-world efficiency of EVs and is expected to help the industry pivot toward an electrified future by facilitating carmakers to sell more EVs. The proposal required gas-equivalent EV mileage ratings to be slashed by 72% by 2027. That means the petroleum equivalency factory was set at a stringent 23.
“The old calculation included a multiplier of nearly seven that significantly inflated the calculated fuel economy of EVs. DOE’s final rule phases out the multiplier while updating other data used in the calculation with more current figures.” Get the InsideEvs Newsletter Sign Up Today Automakers were caught off guard by the initial proposal that an auto industry group said would have resulted in $10.5 billion in penalties for not complying with the proposed fuel economy standards.
