No engines doesn't mean low tech, however. The 16 featured cars are gravity racers built by the world's top auto manufacturers, including Bentley, General Motors, Nissan, Chrysler, Volkswagen, Audi, Mazda, Porsche and Pininfarina. They were a part of this year's Extreme Gravity Racing series. They will be going on the block with no reserve during the 36th Annual Barrett-Jackson Collector Car Event in Scottsdale, Ariz in mid-January.
"The gravity racers are pure speedsters that embody a style of racing exhibited during the golden era of automobiles," said Craig Jackson, president of the Barrett-Jackson Auction Company. "They are engineered for raw competition and demonstrate absolute perfection, with no need for horsepower or supercharged engines. These racers represent the best of the best in automotive design and would be the crown jewel of any collection."
