Discovery channel has been running a four part series called FutureCar for the past few weeks and one of the segments focused on the GM Skateboard chassis that was first shown a few years back, featuring fuel cell power and complete by-wire controls. A variation of the Skateboard is used on the Sequel concept.

The segment doesn't delve too deeply into the technology, but instead focuses on a group of design interns . They were with tasked developing some new concepts that took advantage of the packaging flexibility afforded by low profile chassis and electronic controls. The Ford HySeries Drive system is similar in concept, minus the by-wire controls, and the Airstream concept was also designed to showcase packaging flexibility, even if the aesthetics were questionable.
