This engineering exercise was created under the auspice of a Safety Proposal, a program headed by Frank Winchell. Zora Duntov was unimpressed and opted for a mid-engine design with more stability and continually pursued his idea. Larry Shinoda was assigned as the design leader along with John Schinella. It reflects several of Shinoda's later C3 design characteristics in the fender line, rear window deck area and swooping rear clamshell. The center of gravity is about eight inches in front of the rear wheel at a height of 14.5 inches. Chevrolet ordered XP-819 destroyed in 1969 and turned over the duties to Smokey Yunick. The car was cut apart and unceremoniously stored in Smokey's paint booth until it was discovered by Steve Tate. The current owner later acquired the car and enlisted Kevin MacKay of Corvette Repair, Inc. to complete a frame-off restoration.
