What happens when you collect together the cream of the world’s automotive design engineers from the likes of Porsche, Bentley and GM, give them lots of cash and tell them to have fun? You get the Extreme Gravity Racing Series, that’s what. Also known as the Ultimate Soapbox Derby?

‘The Extreme Gravity Racing Series was borne from Don MaCallister�s vision of creating an exciting venue where corporate participants would come together for fun competitive gravity-powered races with portions of the sponsorship proceeds supporting foster kid programs. Over its four years of life, the races evolved from simple timed ramp races to an increasing emphasis on design elements that included chrome accents, elegant artistic paintwork, and luxury car showroom finishes.’
