Detroit Auto Show: It's here. GM's plug-in hybrid is the Chevy Volt Concept {Autoblog Green}

Jan 7th 2007 7:35AM Definitely a very cool car. The range is the most attractive thing to me. 600+ miles on a tank of gas is good.

I do wonder... what happens to the gas in your tank, if you do a lot of short-range driving, and never use the ICE?

Even drivers who only use the Volt for short-hop driving will keep gas in the tank, Just In Case.
