Brun Motorsport - Constructor History

Constructor History

Walter Brun developed cars throughout the entire history of Brun Motorsport, although only one would bear his name. At the time of the formation of Brun Motorsport, the former Team GS-Sport Sauber SHS C6 was retained by the new team. Brun believed that the car had potential in the C2 class and therefore modified his chassis to adapt a Ford Cosworth V8. Problems with the car eventually led Brun to replace the Ford Cosworth with a turbocharged version of the BMW unit that Sauber had initially used. The car would however be considered too difficult to continue, and Brun opted instead to purchase a Porsche 956.

Later, aftear many years of experience and success with the 956 and later 962, Brun was forced to attempt to catch up to major manufacturers like Jaguar and Mercedes-Benz. Attempting to improve on the 962 platform, Brun began development of their own chassis in 1987. Attempting to overcome the flexing problems that had plagued the factory 962s, these new cars would have a monocoque built by Brun and then assembled with standard 962 parts. Eight of these cars would be built in total, with a few sold to other teams while the rest would join Brun's fleet of existing 962s.

Brun's largest project was the development of the Brun C91 in 1991, in preparation for the 1992 regulation changes. The car was a fresh design, using many elements from the Peugeot 905, Mercedes-Benz C291, and Jaguar XJR-14 such as a large double rear wing and low bodywork dominated by a tall cockpit. With the new regulations banning the turbocharged Porsche flat six, Brun would require a naturally aspirated engine that was on part with Formula One technology. Using elements of the EuroBrun team, Brun would turn to the same team that had supplied engines to the Formula One outfit: Judd. EuroBrun had initially used the outdated Judd CV V8, but Brun was able to get funding for the new EV V8. The car would however suffer mechanical woes from its debut halfway through the 1991 season, and the team would never manage to come to terms with the car before funding would eventually run out.
