160-573: A significant number of continental drivers. The weak pound (a result of the energy crisis) and the increasing cost of importing Chevrolet V8 engines caused some concern and engine regulations for European F5000 were revised to permit engines other than the 5.0 litre pushrod V8s - the DOHC Cosworth GA V6 (based on a unit used in Group 2 Capris was permitted to race at a capacity of 3500cc.

288-652: The IMSA GT Championship in 1981, the old F5000 were now clumsy and slow compared to the new cars . In the UK, the arrival of the Cosworth DFV engine meant that many teams could now afford to build their own chassis around a good engine/transmission package, so Cooper , Lotus and Brabham stopped the production of customer Formula 1 cars. Unfortunately, smaller privateer teams and drivers that entered Britain's non-championship F1 events were left behind, and

320-752: The RAC quickly adopted the American F5000 regulations. A European championship was first run in 1969 as the Guards Formula 5000 Championship. This was renamed to Guards European Formula 5000 Championship in 1970, to Rothmans European Formula 5000 Championship in 1971 and then to ShellSport European Formula 5000 Championship in 1975.

Formula 5000 was also the main component of Australian Formula 1 from 1971 to 1981 and this formula was the primary category contesting the Australian Drivers' Championship during those years and the Australian Grand Prix until 1980. Although still called Australian Formula 1 until 1983, F5000 was replaced by Formula Pacific and Formula Mondial after 1981. While European cars such as

However, the same problem that befell US F5000 happened in Europe, and in 1976 the European F5000 Championship evolved into the Shellsport Group 8 Championship. This was a British-based series for Formula 1 , Formula 2 , Formula 5000 and Formula Atlantic cars, forming

832-525: The world from 1968 to 1982. It was originally intended as a low-cost series aimed at open-wheel racing cars that no longer fit into any particular formula. The '5000' denomination comes from the maximum 5.0 litre engine capacity allowed in the cars, although many cars ran with smaller engines. Manufacturers included McLaren , Eagle , March , Lola , Lotus , Elfin , Matich and Chevron . In its declining years in North America Formula 5000

864-399: Was a never adequately replaced. Nichols and Oliver secured a Swiss tobacco company, Tabatip Cigarillos, to sponsor the team on a limited basis for the 1976-77 season with additional sponsorship coming from Franco Ambrosio for the 1977 season. Shadow faced a tragedy similar to the loss of Revson when Tom Pryce was killed during the 1977 South African Grand Prix when a track marshal ran across

896-546: Was dominated by drivers that were usually seen in Formula 2 or at the back of F1's World Championship grids. Peter Gethin managed to launch his F1 career thanks to his F5000 championship titles.

However, by

960-611: Was inspired by the success of the Can-Am Series, which featured unlimited formula sports cars fitted with very powerful engines derived from American V8s ; the idea was to replicate the concept using open wheel racing cars. F5000 enjoyed popularity in the early 1970s in the U.S. and featured drivers such as Mario Andretti , Al Unser , Bobby Unser , James Hunt , Jody Scheckter , Brian Redman , David Hobbs , Tony Adamowicz , Sam Posey , Ian Ashley , John Cannon and Eppie Wietzes . Increasing costs and Lola domination meant

992-580: Was modified into a closed wheel, but still single-seat sports car racing category. Formula 5000 was introduced in 1968 as a class within SCCA Formula A races, a series where single seaters from different origins were allowed to compete, but which rapidly came to be dominated by the cars equipped with production-based American V8s. The engines used were generally 5 litre, fuel injected Chevrolet engines with about 500 horsepower (370 kW) at 8000 rpm, although other makes were also used. The concept

1024-491: Was powered by a 2993 cubic centimeters (182.6 cu in) Ford Cosworth DFV engine. Having recently only worked with the smooth-revving BRM V12 engines, Southgate did not allow sufficient damping and reinforcement to compensate for the vibration of the flat-plane V8 DFV. This caused some severe reliability issues for the cars, particularly at the start of the season. The Shadow works team cars were finished in an all black scheme, with sponsorship from UOP .
