"no-emission electric motors — which began the automobile revolution — are the technology of tomorrow for cars. but today's batteries can't support the typical driving experience. chevy's volt is a nice compromise. the sedan has an electric motor with a battery that can provide up to 40 miles (about 65 km) of range on a single charge. a gas engine kicks in to recharge the battery while you're driving. since nearly 80% of us drive less than 40 miles a day, that means that unlike the prius, the volt could get drivers off gas altogether. the best of both worlds lands by the end of 2010."
