At the 2007 Detroit Auto Show, General Motors unveiled an eye-catching -- in more than one way -- concept. The Volt's futuristic looks caught the public's attention but it was the technology underneath the concept's skin that was truly noteworthy. It featured a lithium-ion battery pack that enabled the concept to travel 40 miles on a single charge and had a 1.0-liter turbocharged gasoline engine to act as an electricity generator after the battery pack was depleted.
