As part of a strategy to change its image as a technology laggard that's indifferent to environmental concerns, GM has been allowing unprecedented media access as it develops the Chevrolet extended-range electric car. The Volt is expected to go on sale in 2010.

The Converj concept shows what a luxury version of the Volt extended-range electric car could look like. It uses what GM is now calling the Voltec propulsion system, which allows a car to drive up to 40 miles on plug-in electric power only. If extra range is needed, the car can then rely on a small on-board gasoline engine.
