Chaparral

Chaparral was a racing team best known for its innovative prototype racecars. The first featured a giant adjustable rear wing which worked like an airplane brake. This improved aerodynamics and handling. The second featured a design which improved ground effects and led to its nickname the "vacuum cleaner". Chaparral went on to have great success in Can Am and endurance racing until the rules were changed outlawing their cars. Chaparrals were usually powered by Chevrolet.
