General Motors Chairman Rick Wagoner and Vice Chairman Robert Lutz revealed the Chevy Volt Concept at the Detroit Auto Show this afternoon. The Volt, as we revealed earlier, is an electric car with range extension capability thanks to an onboard internal combustion engine that acts as a generator for the batteries, which gives the Volt a range up to 640 miles. We don't want to steal AutoblogGreen's thunder, so you can check out their full coverage of the unveiling and a high-res photo gallery of live shots taken during the reveal.
