The Tyrrell 020C was a racing car from the British team Tyrrell , which was used in nine races of the Formula 1 World Championship in 1993 . It was the first Tyrrell vehicle to be fitted with a Yamaha engine. It was a transitional car that was brought to the start until the completely newly developed Tyrrell 021 was ready for use.

background

The traditional racing team Tyrrell had experienced a number of sporting failures in the 1980s. In 1989 and 1990 the team found their way back to the midfield with the innovatively designed models 018 and 019 ; both years it finished fifth in the constructors' championship. For the 1991 season , the team succeeded in receiving highly developed ten-cylinder engines from Honda instead of the previously used customer engines from Cosworth . Team boss Ken Tyrrell hoped that this would result in a further increase in performance. As an emergency vehicle, Tyrrell reported the Tyrrell 020 developed by Harvey Postlethwaite in 1991 , which, however, did not meet the expectations placed on it; the team fell in the year-end standings to sixth place in the constructors' championship. Honda ended its alliance with Tyrrell after just one year. For 1992 , Tyrrell switched to Ilmor engines which were built into a chassis called the Tyrrell 020B . The 020B was technically identical to last year's 020. The connection to Ilmor also ended after only one year. For 1993, Tyrrell received engines from Yamaha that were given to the team at no charge. The team started the season with the 020C, which was a further evolution of the 020 developed in 1991.

technology

Yamaha OX10A V10

The Tyrrell 020C was a "quick and cheap" revision of the 020. The main changes involved adapting the two-year-old Postlethwaite design to the Yamaha engine. The chassis, the running gear and the body remained almost unchanged. The development of the 020C was led by Mike Coughlan .

A 3.5 liter ten-cylinder engine from Yamaha with the designation OX10A served as drive. The power unit had no connection to the earlier Yamaha engines used by Zakspeed in 1989 (OX88, eight cylinders) and in 1992 by Jordan (OX99, twelve cylinders). Nevertheless, the OX10A was not a new design. After an unsuccessful season with Jordan, Yamaha ended its own engine program and instead hired the British racing engine manufacturer Engine Developments ("Judd") to develop Formula 1 engines for 1993 . The Yamaha engine of the 1993 season was technically a further development of the Judd GV ten-cylinder, which had been used in 1991 by Scuderia Italia and 1992 by Brabham and Andrea Moda . The main change compared to the Judd GV was the use of variable intake manifolds and valve pneumatics. The engine was poorly performing and unreliable.

Races

The drivers of the Tyrrell 020C were Ukyō Katayama and Andrea de Cesaris . Both drivers suffered from the insufficient stability of the engine. Katayama and de Cesaris each failed four times due to defects in the engine area or in the drive train. In the first race of the year in South Africa , none of the cars survived the first lap. In total there were only four target arrivals with the 020C; the drivers were each lapped several times. Katayama was 17th in Canada , five laps behind, and 13th in Great Britain after four laps. De Cesaris achieved the best result of an 020C at the Monaco Grand Prix , which he finished tenth, two laps behind.

From the British Grand Prix de Cesaris had the new 021 available; Katayama also got a 021 in the following race.
