Formula Ford is an entry-level class of single seater, open-wheel formula racing. The various championships held across the world form an important step for many prospective Formula One drivers. Formula Ford has traditionally been regarded as the first major stepping stone into formula racing after karting. The series typically sees professional career minded drivers enter alongside amateurs and enthusiasts. Success in Formula Ford can lead directly to other junior formulae such as a Formula Renault 2.0 or even an F3 seat. Formula Ford is not a one-make championship. It allows freedom of chassis design, engine build and numerous technical items of specification on the car. This opens the door to many chassis manufacturers, large and small. Many other single-seater formulae impose fixed specifications. Only two other professional single seater racing formulae in the world offer the same freedom of chassis and engine build: Formula Three and Formula One. ==History== The origins of Formula Ford began in the early 1960s, where motor racing schools such as The Jim Russell school and Motor Racing Stables featured single seat Formula Junior and Formula 3-like machines from world class constructors like Cooper and Lotus. Many aspiring Formula 1 stars looked to these schools in the hope of learning the craft and also looking the part. However, although there was no shortage of aspiring drivers, these schools had much trouble avoiding bankruptcy. The 1 litre Formula 3 engines, the 1.1 litre Coventry Climax FJ and later the Ford Anglia 105E, cost around £3,000 at the time in addition to the Dunlop racing tires which cost £80 a set. Furthermore, these engines were incredibly fragile to boot, meaning they had a tendency to self-destruct. All these factors contributed to a steep maintenance and upkeep cost of the schools. In 1963, Geoff Clarke; the owner of Motor Racing Stables, moved his racing school to the Brands Hatch circuit. This brought him in contact with John Webb; Managing Director of Developments at Brands Hatch. At about this time, two of the school’s Lotus Formula Junior chassis were fitted with a standard 1498cc Ford pushrod engine as featured in the then-recently introduced Cortina GT saloon. The 1500 Cortina, with its sensational reliability and horsepower output fairly close to “F3 proper” proved a resounding success in the school. The earliest experiments with radial tires bore fruit as well: the students of the day didn’t care that these weren’t the racing engines or racing tyres, just that the cars were equal. At an informal meeting at the December 1966 racing car show day at Olympia, John Webb and Geoff Clarke were discussing the possibility of building a fleet of identical open wheel race cars based on the success of combining the Ford power plant and road wheels, radial tyres, and Formula junior style chassis. Not only would they make ideal school cars, but would also provide a new entry level formula for a race series. They felt if they called it “Formula Ford” they could get backing from Ford itself. Webb was on the phone the next day to Ford competition manager Henry Taylor, who agreed to provide Clarke and MRS with 54 Cortina GT engines at £50 each (£15 below retail). Webb also approached the Royal Automobile Club's competition director, to establish rules for this new class. Late in 1967, Ford announced the new Formula Ford class to the world. Geoff Clarke then set about approaching existing race car constructors to build the first Formula Fords. Both Bruce McLaren and Jack Brabham turned down the idea; Colin Chapman however dusted off the then obsolete Lotus 31 Chassis and reinvented it as the Lotus 51. He agreed to provide the first of two 25 car batches at £850 per car. The only stipulation Chapman had was that a Renault gear box was used. This proved to be fundamental weak point in the drive train. Difficulty with the Renault transmission resulted in a failure to continue with the second batch of cars for MRS. Jim Russell approached Colin Chapman to supply Formula Ford cars for his own school. Chapman insisted Russell match Clarke’s 50 car order; Russell would only commit to 10 cars so the deal fell through. Russell then approached Allan Taylor who built the Alexis car and a deal was struck to jointly produce the Russell-Alexis. This car had the Hewland racing gear box which made the car more expensive (£999), but was more reliable and allowed interchangeable ratios. The first standalone Formula Ford race took place at Brands Hatch on July 2, 1967. Of the 20 cars that competed, 10 were MRS Lotus 51’s, including the eventual winner, Ray Allan. The Russell-Alexis car won its debut race in August 1967, and by 1968 54 Russell-Alexis had been sold. Based on this success Jim Russell opened 2 more racing schools in Britain, another in Canada, and another in the United States. Chapman and his Lotus 51 did recover, replacing the troublesome Renault gear box with the Hewland unit, even claiming Jim Russell as a customer in 1968. 1968 also saw the debut of Meryln as a Formula Ford constructor, dominating sales for that year. Other new manufactures included Crosslé Car Company, Dulon, Elden Racing Cars, Hawke Racing Cars and Royale Racing Cars, together with existing constructors such as Brabham choosing to build a Formula Ford chassis. As the production Ford Cortina engine evolved to a new 1600cc crossflow unit, so did the Formula Ford regulations. Increasing costs forced them to relax the £1,000 price ceiling on Formula Ford as blueprinting of the engine was now allowed. Belgium hosted the first race outside England, in 1967. Formula Ford racing quickly spread across Europe and North America, with the first official Formula Ford race in the United States on March 23, 1969. By the late 1960s and early 1970s, Formula Ford had established itself as a direct path to a seat on a Formula 1 car, the highest level in open wheel motorsport. Australian Tim Schenken won over 2 dozen Formula Ford races in 1968, two years later he was driving a Formula 1 car for Frank Williams. Emerson Fittipaldi impressed during the 1970 Formula 1 Grand Prix Season after a short stint in Formula Ford. In 1970, he became the first Formula Ford graduate to win a Formula 1 Grand Prix. In 1972, he became the first Formula Ford graduate to win the Formula 1 World Championship. Currently, Formula Ford racing exists in two main forms: National Series for aspiring 'career' drivers run around the world which have used the 1600 Duratec engine, (which replaced the heavier but not significantly more powerful Zetec engine in 2006), and for 2012 are beginning to adopt the new EcoBoost 1600 turbo engine; and a mainly amateur, club-racing series attracting serious enthusiasts using the now elderly 1600 Kent engine with which the formula ran from the mid-1960s to mid-1990s. Whatever the engine of the Formula Ford car, it has long provided a relatively inexpensive way for drivers to race purpose-built racecars. There are many Formula Ford 1600 series for drivers of the older Kent-powered cars. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Formula Ford」の詳細全文を読む スポンサード リンク
