CNN reports that GM unveiled a plug-in hybrid vehicle that uses a small gasoline engine only when necessary to recharge the batteries. The Chevy Volt can drive for about 40 miles of "suburban driving" and recharges in about 6.5 hours.
Maybe GM is trying to make up for killing the EV-1 (see "Who Killed The Electric Car" for more information about this reference) by being the first US car company to bring this much-needed product to market!
My hope is that GM - and other car companies - will unveil plug-in hybrids like the Chevy Volt as soon as possible. We need to move away from a transportation sector powered by oil and toward one that is powered by electricity. With plug-in hybrids, the stage could be set for cars powered by renewable-based energy.
