Lots 1580 through 1588 are specially constructed gravity racers built by the world's leading design studios. The concepts reflect many different genres of auto racing, including Formula 1 and Bonneville while others look like a Pinewood Derby car on steroids.
Some of the automakers included in the auction include Pininfarina, Audi (my favorite that is shown), GM, Chrysler, Nissan, Volvo, Mazda, VW, Porsche and Bentley.
These are more than souped up Soapbox Derby cars. Exotic materials and body designs generated from high-tech CFD computer analysis are the norm. Some cars may have even been tested in the wind-tunnel.
