Zora Arkus-Duntov was greatly influenced by the Auto Union and Mercedes race cars of the pre and post WW II era of racing. AWD was often part of the advanced engineering of the world’s best racecars, so it was no surprise that Duntov wanted AWD in his Corvette prototype to race at Le Mans. “Getting there” in a company that makes consumer cars would be a challenge, so Zora was limited to the parts bin. Duntov built his AWD racer using a 2-speed Powerglide automatic transmission with a modified 11-inch torque converter for the rear wheels, and a Corvair Powerglide transmission with a modified 10-inch torque converter just ahead of the front wheel centerline. There are many ways of driving four wheels in an automobile, but this was so unique that on November 19, 1968 Duntov was awarded U.S. Patient #3,411,601 for the design.
