General Motors began its second century by revealing the production version of the Chevrolet Volt. The automaker hopes that the electric-powered Volt will make GM a vehicle technology leader. The Volt is planned to go on sale in November 2010 with the potential for an Opel version in Europe in 2011. Estimates of Volt’s starting price range between $30,000 and $40,000. GM also estimates that the Volt’s battery can be charged for less than $1.
