GM to unveil an plug-in hybrid prototype in Detroit
General Motors is likely to unveil a prototype plug-in hybrid at the North American International Auto Show 2007 as part of its company-wide focus on "electrifying" the car, GM officials said Thursday.
The prototype’s advanced technology would have an extended driving range on battery power alone and would also have a diesel or gasoline engine that could power the car when the battery was low.
GM sees hydrogen fuel cells as the solution to ending the country’s reliance on oil. However GM believes the key is using electricity — through hybrids, batteries and hydrogen fuel cells — to run vehicles, not gasoline.
Plug-in hybrids are gas-electric vehicles that can recharge their batteries with an extension cord and a normal wall outlet. Like conventional gas-electric hybrids, which have two drivetrains, a plug-in hybrid can also recharge its batteries through a regenerative brake system while on the road. The range on plug-in cars has typically been no more than 20 or 30 miles on battery alone.
