1964 Ford GT40 Prototype
In the early sixties, Henry Ford decided that his company would brand its products with motoring performance by contesting international endurance racing, including the 24 Hours of Le Mans. Ford had already gained some experience in motorsport, providing Carol Shelby with power plants for his Cobra 427, but the new program would be the next step.
Ford’ first move towards their new goal was to purchase Ferrari but fortunately the Italian firm stood strong and remained independent. Thus began one of the largest and most famous rivalries in motor sport history: Ford vs Ferrari.
Ford’s challenge was to make a car fast enough to overcome the Ferrari 275P and later 330 P3. They started with the 1964 Ford GT, a well funded prototype, which would become the legendary GT40 a year later.
Two Cars Were Directly Related to the Ford GT.
The 1962 Ford Mustang I Concept showcased Ford’s early idea of a Le Mans racecar. Roy Lunn and Len Bailey were responsible for the development of this show car which stood as a prelude to the large motor sports campaign which would follow. Lunn later searched for companies, beyond Ferrari, to make a car embodying the Mustang I’s concept.
A separate entity within Ford called Kar Kraft was managed by Lunn to overlook the Ford GT program. Kar Kraft negotiated the deal with Eric Broadley to develop a Ford version of his promising Lola Mark 6. Together, the companies would work in a new facility called Ford Advanced Vehicles (FAV). John Wyer from Aston Martin became the managing director of FAV and also managed the european racing efforts.
Development
Several people including Lunn, Phil Remington and Len Bailey were sent to Slough, England to manufacture the first car with Eric Broadley and Lola. It was decided the Ford GT would be made in Slough to take advantage of the British specialists such as Abbey Panels, Mouldings Ltd and Harold Radford Ltd. While most of the manufacturing was completed in England, some development work was carried out at Dearborn, Michigan. Still, in most regards, the GT was built with US-funded, British expertise.
In North America, Ford relied on new technology to assist in the development of the GT40. Most of the work carried out by Ford included aerodynamic testing using a scale model in the Maryland wind tunnel. Ford found heavy lift at high speeds and to revert this problem, an additional wing was fixed. It was mounted just below he nose of the car.
Ford also assisted Lola with computer-aided calculations. They were necessary to ensure the aerodynamics were proper under braking. Anti-diving suspension geometry was also setup using computer calculations.
In Detail
Race-proven engineering from Lola provided a basis for the Ford GT. It’s mid-ship layout was becoming normal practice for race cars but were still many years behind the Formula One cars that pioneered the trend.
The chassis was made up of complicated pressed steel sections forming a single tub. Most of the rigidity came from twin pontoons which ran down the side of the car and contained the fuel cells. These chassis were manufactured by Abbey Panels of England as a completely steel product. Thus, the chassis accounted for much of the Ford GTs hefty weight.
Interior space of the Ford GT was well thought out. The seats were perforated with holes to provide ventilation to the driver. Additionally the inside of the seats received fresh air from a high-pressure area on the front of the car. This made the Ford GT40 one of the first racecars to have a conditioned seat. It was aspects like the seat and the adjustable pedals which increased driver stamina and made the GT40 more habitable.
Conclusion
As Ford was the first Detroit giant entering international prototype racing, the press was increasingly interested in the Ford GT project. Reports on the car Ford GT40 were published abundantly in automotive publications. The first car, chassis #GT101, was shown to the press at the 1964 New York Automobile Show. Later appearances at Le Mans, Nurburgring and Reims with addional cars increased Ford’s publicity.
It is not surprising that the GT40 did not take any remarkable victories in it’s first year. The entirely new car was up against competition that had developed prototype cars for decades. What the 1964 Ford GT did do is make a favorable impression on the racing industry and motoring press.
