Frank Weber, GMs Volt vehicle line executive talked about the Chevy Volt the day before the Chicago Auto show.

The questions after the speech are usually the most interesting.

Is the Chevy Volt a flex-fuel vehicle? If so, what is the difference in miles per gallon between gasoline and ethanol?

How does the Chevy Volt deal with cold start?

Does weight matter as much in the electric car versus aerodynamics?
