Toyota weighing in early on what the Volt is and is not

The production Chevrolet Volt electric vehicle (right) debuts on the West Coast at the Alternative Energy and Transportation Expo in Santa Monica, California Friday, September 26, 2008. Next to the Volt is the EV1, the electric car developed by General Motors in the mid-90's that pioneered electric vehicle technology, much of which is used in the Chevy Volt.
