Peter Harry Sutcliffe, a British textile manufacturer from Huddersfield, was active in sports car racing until 1967. Between 1959 and 1967 he won the 1964 Prix de Paris at the Autodrome de Linas-Montlhéry, and the 1965 Pietermaritzburg 3 hours. He raced in Aston Martins, Jaguar D-Type and E types, Shelby Cobra Daytona, Ford GT40s and works Ferrari 330P4s.

The Shelby Daytona Coupe is an American sports-coupé. It is related to the Shelby Cobra roadster, loosely based on its chassis and drive-train developed and built as an advanced evolution. It was engineered and purpose built for auto racing, specifically to take on Ferrari and its 250 GTO in the GT class. The original project had six Shelby Daytona Coupes built for racing purposes between 1964 and 1965, as Carroll Shelby was reassigned to the Ford GT40 project to compete at the 24 Hours of Le Mans, again to beat Ferrari in the highest level prototype class. With the Shelby Daytona, Shelby became the first American constructor to win a title on the international scene in the FIA International Championship for GT Manufacturers in 1965. In 2014, the first Cobra Daytona Coupe became the first vehicle recorded under a U.S. federal program for documenting historically important national treasures.
