GM Chairman Rick Wagoner and Vice-Chairman Robert Lutz just unveiled Chevy Volt Concept to the mass of press here at Cobo Hall. Although they didn't really reveal anything new that wasn't in the previous stories about the Volt, they did emphasize that they don't consider this car a hybrid. As far as GM is concerned a hybrid is a car that drive the wheels either electrically or via an internal combustion engine. Since this vehicle only drives the wheels via an electric motor, they call it an EV.
