All they have to do is produce a hybrid with today's technology and the stylings of that Volt concept car, and GM can get into the hybrid market in a big way. That would be a logical way to gain market share, something GM brass is apparently disdainful of doing.
That's for sure. That would be more fun to drive than my gas-sipping Saturn. Hybrids really do provide "free energy," in that they harness braking energy that is usually dissipated as heat.
