The Tyrrell 004 is a racing car from the former British Formula 1 team Tyrrell . Together with the largely identical Tyrrell 002 and Tyrrell 003 , it formed a model family that followed in 1971 on the Tyrrell 001 prototype presented the previous year . The 002/003/004 family established Tyrrell's reputation as one of the leading racing car designers of its time. Like its sister models, the 004 was a one-off. It was only intended as a replacement vehicle from the start and was only used in three world championship races in the works team. The 004 is the only example in the model family that has been sold to an independent customer team.

The model family 002/003/004

Tyrrell regularly identified its racing cars with a consecutive three-digit number code. Until 005, the name was not linked to a series, but to individual chassis. The 002, 003 and 004 were therefore each unique pieces. From a technical point of view, however, they were almost identical. Chassis 002 and 003, which were completed in January and April 1971 respectively, received a number of technical improvements over the course of the year. The 004, which was not completed until the end of 1971, was equipped with these modifications right from the start.

History of origin

The Tyrrell Racing Organization had competed in Formula Junior , Formula 3 and Formula 2 since the 1950s . After team founder Ken Tyrrell had temporarily headed the Formula 2 and Formula 1 works teams of Cooper in the 1960s , he brought his own racing team to Formula 1 in 1968. In the first two years, Tyrrell was a pure customer team, the chassis from Matra combined with engines from Cosworth . When Matra made the further chassis delivery to Tyrrell dependent on the use of French engines for the 1970 season, Ken Tyrrell ended the relationship with Matra. Since no other competitive customer chassis were available, he decided to build his own racing car. After a short transition period with chassis from March , the first prototype, the Tyrrell 001, was ready for use in August 1970. The car, designed by Derek Gardner in great secrecy, was fast, but had numerous teething problems, including insufficient oil and fuel supply, as well as reliability problems in the mechanical area. The 001 competed in five world championship races in 1970 and 1971, but only crossed the finish line once: Stewart finished second in the opening race of the 1971 season in South Africa . In addition, there were the only finishes in Formula 1 races that did not have world championship status .

Based on the 001, Gardner constructed the model family 002/003/004. They were further developed and improved versions of the 001, to which they were still very similar in essence.

construction

The Tyrrell 004 had an aluminum monocoque that was formed from thicker aluminum sheets than its predecessor. The monocoque was 10 cm longer than that of the 001 and offered more elbow room. The roll bar behind the driver had been reinforced. One-piece wishbones were used at the front. The 004 had double disc brakes from Girling. Tyrrell used the established Cosworth DFV engine with 3.0 liter displacement as drive; a five-speed transmission from Hewland (FG40) took over the power transmission . Tyrrell, however, was one of Cosworth's preferred customers. While most DFV engines made around 435 hp, Tyrrell drivers had specially redesigned versions that delivered 10 to 15 hp more.

The body corresponded to the 002 and 003 in their last form. Right from the start, the 004 had a plastic air scoop over the engine and a new front spoiler that extended across the entire width of the vehicle and was supposed to direct the air over the front wheels.

Races

1972

Jackie Stewart drove it at the Monaco Grand Prix ; he finished fourth in 004. Tyrrell then gave the car twice to Patrick Depailler , who was the third driver of the Tyrrell works team in France and the USA . In France he was not classified, in the USA he was seventh.

1973 and 1974

At the end of 1972, Tyrrell sold the 004 to the South African racing driver Eddie Keizan , who used it in the South African Formula 1 Championship in 1973 and 1974 and also competed in the Formula 1 World Championship at the South African Grand Prix in both years . Keizan was not classified in the 1973 world championship run, and in 1974 he finished 14th.
