The

Chevrolet Volt

is unique among

electric vehicles

because you have two sources of energy. You have an electric source-a battery-that allows you to drive gas-free for an EPA-estimated 35 miles. And there's also an onboard gas generator that produces electricity so you can go up to a total of 375 additional miles on a full tank of gas. So if you want to drive using only electricity, you can. If you want to drive using electricity and gas, you can do that too. Volt is the first for two very good reasons.
