GM is testing lithium-ion batteries for future use in the Volt which will be released in about 2 years. The Volt is an extended range plug in electric vehicle. The tests are being conducted in Warren and the malibu is the test vehicle.The Volt can travel 40 miles and 150 miles with the use of a conventional engine to charge the batteries.The up side to this is that althrough no design elements have been released, they are using the Malibu for a test vehicle so this could be a decent size car, not the roller skate we have seen in the latest electric cars.
