Chaparral 2H 1969

Never one to be complacent, Jim Hall noted that the increasing down-force also created enormous drag. Seeking a competitive edge, the 2H was built in 1969 as the replacement for the 2G to minimize drag, rather than maximize down-force. However, the anticipated gains in speed were more than offset by the reduced cornering speeds and the car was consistently slower than anticipated.

A failure, it eventually was fitted with a huge wing.
