CHEVY VOLT
General Motors' plug-in hybrid differs from today's hybrids in that drivers will be able to recharge the batteries with an electrical outlet instead of letting them recharge while the car runs on gasoline. Another difference: The Volt's gasoline motor does not power the drive wheels; instead, after the vehicle exceeds its 40-mile range on batteries only, the gasoline motor turns a generator to recharge the batteries that feed the electric drive. The lithium ion batteries for this vehicle still remain a challenge in cost and volume manufacturing, but GM is promising it can make first deliveries, in limited numbers, by November 2010.
