Sema Preview: Pontiac Solstice SD-290 Concept.

GM released only this single view of the Pontiac Solstice SD-290 Concept for SEMA. The Solstice features a cover over the passenger compartment that is reminiscent vintage single-seat club race cars and includes a new windscreen and separate review mirror mounted in the middle. It's likely powered by something that's green and mean. Look for further updates this week.
