Video: Unveiling of the Chevy Volt concept car at the NAIAS

As automakers look to curb fuel consumption, the North American International Auto Show saw the unveiling of a new electric-powered concept car by General Motors (GM) - Chevy Volt. The Chevy Volt is a battery-powered electric vehicle that uses a gas engine to create additional electricity. The Volt can also run on E85 to deliver 150 miles-per-gallon (mpg). During the show, GM also introduced a new family of propulsion systems - the E-flex System - which is a series of vehicles that will produce energy from gasoline, ethanol, bio-diesel or hydrogen. The Volt is the first vehicle in the E-flex system.
