The Shelby Daytona (also referred to as the Shelby Daytona Cobra Coupe) was a coupe based loosely on the AC Cobra roadster. It was built for auto racing, specifically to take on Ferrari in the GT class. Just six Daytona coupes were built in 1964 and1965, with Shelby reassigned to the Ford GT40 project after that. Pete Brock designed the car's bodywork, while Bob Negstad designed the car's suspension. Negstad also designed the chassis and suspension for the GT40.
