Although details are still sparse, rumor has it that tonight GM’s Vice President of Global Design, Ed Welburn will join Jay Leno to unveil their extremely confidential car design collaboration. They’re calling it a ’super car’ that all started as a sketch on a bar napkin (shown here). It’s clearly futuristic and early whispers indicate it’s eco-friendly– and that makes us very happy to hear. Stay tuned for more info and pictures of the launch. We’re planning on a few high-five sessions with Leno and GM executives afterwards– that is, if we like what we see.
