GM places bets on alternative fuel vehicles

By showing the Chevrolet Volt plug-in electric concept car this month at the North American International Auto Show, General Motors Corp. has staked its reputation — and a large chunk of change — on developing cars and trucks that can be propelled by something other than just gasoline.

But development of the Volt’s so-called E-flex propulsion system is dependent on advancements in lithium-ion battery technology. Such an advanced lithium-ion battery does not exist, yet.

Skeptics argue that its development is far off.
