Chevrolet Volt Said to Get 230 Miles Per Gallon in City Driving
GM is beginning to pour on the coals here -- will the car deliver at a price we can afford? Tentative EPA methodology results show 25 kilowatt hours/100 miles electrical efficiency in city cycle. Plugging in daily is its key to high-mileage performance. The Volt will receive ?a higher number than anyone would expect,? GM Vice Chairman Bob Lutz, 77, said by e-mail yesterday. He wouldn?t say what the mileage will be.
