1965 Shelby Daytona
Seen at Goshen, CT Car Show
During 1964 and 1965, Ford entered their six Shelby Daytona Coupes in numerous races through the British Alan Mann Racing Ford factory team, as well as a temporarily selling or leasing to other racing teams such as “Tri-Colore” of France and Scuderia Filipinetti of Switzerland.
During this period, Shelby Daytona Coupes raced in GT Division III, for engine displacements over 2000 cc. They competed at numerous 500 km, 1000 km, 2000 km, 12 hour and 24 hour races on the World Sportscar Championship circuit, including events at Le Mans, Daytona, Sebring, Imola, Reims, Spa Francorchamps, Goodwood Circuit, Oulton Park, Circuito Piccolo delle Madonie, the multi-race Tour de France Automobile, Enna, Rouen, Monza, and Nürburgring.
The Shelby Daytona Coupes, in their first year of competition, finished second (by 6 points) in GT III class for the 1964 World Sportscar Championship season. The Shelby Daytona Coupes won the GT III class (by 19 points) for the 1965 World Sportscar Championship season.
Carroll Shelby, after winning Le Mans in 1959, wanted to return to Europe to beat Enzo Ferrari at Le Mans with a car of his own design. Having developed the AC Cobra/Shelby Cobra into a successful GT race car, he realised that the weakness of the open-cockpit sports cars at Le Mans was the aerodynamic drag which limited top speed on the 3 miles (4.8 km) longMulsanne Straight to around 157 miles per hour (253 km/h), nearly 30 miles per hour (48 km/h) less than the Ferrari 250 GTO, which itself could hold speeds of circa 186 miles per hour (299 km/h). Given the length of this straight, this speed differential represented a loss of over 10 seconds per lap which could negate any power and acceleration advantage that the Cobra had in the slower sections.
Shelby asked employee Pete Brock to design the Daytona's aerodynamic bodywork and Bob Negstad to design 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.
After sketching the proposed design on the floor of the Shelby America workshop, starting with the roadster chassis crashed at the 1963 Le Mans race, Brock removed the bodywork and placed a seat and steering wheel in alignment of where he felt that they should be. He then placed driver Ken Miles in the car, and using scrap wood and gaffer tape, designed the windscreen - the first component to be manufactured for the car. He then interspaced wooden formers, and using these as a guide hand-beat the aluminium bodywork for chassis #CSX2287 around them.
Shelby conferred with an aerodynamics consultant from Convair who said that the design needed to be extended on the tail by at least 3 feet (0.91 m), but Brock stood by his design. Miles took the car to the Riverside Raceway, and on the 1 mile (1.6 km) main straight, took the car on his first five laps to 186 miles per hour (299 km/h), admittedly after it had been found to have "almost flown, lightening the steering a great deal" at speeds above 160 miles per hour (260 km/h). It took another 30 days of development before Miles signed off the car, clocked at that point capable of speeds over 190 miles per hour (310 km/h).
