DOE Proposes Rules to Reduce Electric Vehicle Milage Ratings to Meet Fuel Economy Rules.

The U.S. Energy Department (DOE) has proposed new fuel economy rules that would lower the mileage ratings for electric vehicles (EVs) in an effort to comply with existing fuel economy standards. The new proposal would reduce the efficiency ratings of electric vehicles by about 10%, lowering the mileage rating for an EV from 125 miles per gallon equivalent (MPGe) to 113 MPGe. This current system of calculating the petroleum equivalent fuel economy has not been updated in over two decades.
