General Motors considers their Chevy Volt as an electric car where as the EPA wants to classify it as a hybrid.
PC Magazine explicates, “Its drive train is entirely electric, since the companion gas engine powers a generator, not the car itself. The Volt is not a hybrid in the usual sense, in other words. GM claims it can run 40 miles before the gas engine even kicks in.”
The car applies its batteries to render most of its ability, setting off the electric generator only when they are exhausted to a certain point. The car is so planned that it arrives to its destination at approximately 30%-35% of the battery’s status of charge.

For hybrid cars like these, you will receive a  nice discount on your insurance for your cars in many states.
