ETV proposes use of more than one standard

ETV Motors, an Israeli company that specializes in self-charging hybrid-electric propulsion systems for cars, has suggested in a letter to the Environmental Protection Agency (EPA) that the U.S. government consider a new multiple standard in rating fuel efficiency. ETV Motors Chief Executive Officer Dror Ben-David says ETV advocates a three-pronged rating for fuel efficiency: one number to show how far the car can go on a single plug-in battery charge, a second number to show how energy intensive the battery is, and a third for how much gasoline it consumes to drive a generator or the wheels when the battery runs out.
