Brun Motorsport

They competed as a Porsche privateer team in sports car racing for their entire existence, running in a multitude of international championships.

The new team also kept Hans Joachim Stuck and Harald Grohs as their drivers, with Walter Brun himself also doing driving duties.

Following initial problems with the Sehcar, Brun became one of the early privateer owners of a Porsche 956, which was used in both the World Sportscar Championship and Deutsche Rennsport Meisterschaft.

The team began to dominate in the combined Interserie-DRM series, taking five victories and earning Hans Joachim Stuck second in the drivers' championship behind Joest Racing's Jochen Mass.

With their great success and hoping to aid their driver Oscar Larrauri move into Formula One, Brun joined with Euroracing to form the EuroBrun team.

Although Walter Brun provided a large amount of monetary investment, the team was run more by the Euroracing side.

Following a third at the 24 Hours of Daytona, Brun would abandon their small IMSA GT concern and instead moved to the All Japan Sports Prototype Championship, where they also scored a third on their debut.

At the same time, the World Championship was beginning to phase in new regulations which would leave the 962s that Brun campaigned ineligible starting in 1992, and Porsche planned no replacement for the cars.

However the financial strain of the EuroBrun team, the C91 project and a lack of results to attract sponsorship became too much, and Brun Motorsport closed before the 1992 season.

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.

Later, after 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 overcome the flexing problems that had plagued the factory 962s, these new cars had a monocoque built by Brun and were then assembled with standard 962 parts.

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 required a naturally aspirated engine that was on par with Formula One technology.
