General Motors says an electric car capable of driving 500 miles (800 kilometres) on a single U.S. gallon of gasoline could be on sale by 2010. The Chevy Volt concept car uses the same high-power lithium-ion batteries found in laptop computers. They can power a small car up to 64 kilometres on a single charge -- then keep going as a tiny gasoline engine kicks in to drive an on-board generator.
Some analysts worry the public has heard automakers cry wolf once too often about an electric solution to western dependency on petroleum fuels. But several were optimistic about the Chevy Volt.
Is this realistic? What will it cost?
