The Shelby Daytona Coupe (also referred to as the Shelby Daytona Cobra Coupe) was a coupé based loosely on the AC Cobra roadster chassis and drive-train. It 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. With this car Shelby became the first American constructor to win a title on the international scene at the FIA World Sportscar Championship in 1965.
