Is the Chevy Volt just hype?
Almost every major auto manufacturer has now announced plans to offer a plug-in hybrid vehicle that can run on electricity for 20-40 miles before switching to gasoline. Since half of American cars travel under 25 miles a day, plug-ins allow people to do most of their driving on electricity, but still have a car for long-distance trips that can be easily and quickly refuelled with gasoline.
