## Abstract

The Department of Energy (DOE) is revising its regulations on electric vehicles to provide a petroleum-equivalency factor (PEF) and procedures for calculating the petroleum-equivalent fuel economy of electric vehicles. The petroleum-equivalent fuel economy values of an automobile manufacturer's electric vehicles may be included in the calculation of that manufacturer's corporate average fuel economy (CAFE), according to regulations prescribed by the Environmental Protection Agency and the Department of Transportation.
