GM, Discovery collaborate for car design documentary

Discovery Channel and GM are taking viewers behind the closely guarded doors of GM Design as part of a new, four-part documentary. Set to debut in 2007, the Discovery Channel program will examine the future of automotive engineering - from design and alternative fuel sources to advanced materials and in-vehicle electronics. With access to the GM Design internship program, the documentary will include elite young designers as they develop eight vehicles - each based on GM's advanced hydrogen fuel cell technology - from initial sketches through digital models to finished design properties. Along the way, viewers will get a rare look at the design studios, confidential proving grounds, aero labs and engineering centers. The Leftlane Perspective: Last time GM was involved in a documentary, the automaker previewed a new Cadillac concept car. Will we get some surprises this time, too?
