Ford Shelby Daytona Coupe
The Shelby Daytona Coupe, was built for auto racing, specifically to take on Ferrari in the GT class. Just six Daytona original coupes were built between 1964 and 1965. Shelby was reassigned to the Ford GT40 project after that to go compete at the 24 hours of Le Mans, again to beat Ferrari. Pete Brock designed the Daytona's aerodynamic bodywork, while Bob Negstad designed the car's suspension. Negstad also designed the chassis and suspension for the GT40 and the CSX 3000 series Shelby Cobra, often referred to as the "coil-Spring Cobra" chassis. Due to its slippery shape, with the same Ford 289 drive-train and chassis as the 289 Cobra roadster it was much faster at top speed.
