{"abstract":"The U.S. Department of Energy (\"DOE\") proposes to revise its regulations regarding procedures for calculating a value for the petroleum-equivalent fuel economy of electric vehicles (or \"EVs\") for use in the Corporate Average Fuel Economy (CAFE) program administered by the Department of Transportation (DOT).
