Brun Motorsport

Brun Motorsport GmbH was a Swiss auto racing team founded by driver Walter Brun in 1983. They competed as a Porsche privateer team in sports car racing for their entire existence, running in a multitude of international championships. They notably won the World Sportscar Championship in 1986 and later became a full-fledged chassis constructor. Brun was also briefly part of the EuroBrun Formula One team from 1988 to 1990. The team was eventually dissolved in 1992.

Following several years of competing for Team GS-Sport and their partner Sauber in the World Sportscar Championship (WSC) and Deutsche Rennsport Meisterschaft (DRM), Walter Brun would take over the ailing GS-Sport company and rename it Brun Motorsport for the 1983 season. Brun initially took over GS-Sport's BMW M1s and a Sauber SHS C6, modifying the later into what became known as the Sehcar C6. The new team would also keep Hans Joachim Stuck and Harald Grohs as their drivers, with Walter Brun himself also doing driving duties.

Following initial problems with the Sehcar, Brun would become one of the early privateer owners of a Porsche 956, which was used in both the World Sportscar Championship and Deutsche Rennsport Meisterschaft. The 956 would immediately boost Brun's performance, as the team quickly took their first victory that season at an Interserie event at Autodrom Most with Walter Brun driving. This would be followed by a fourth place at the 1000 km Spa.

Abandoning the Sehcar project for 1984, a second 956 would be purchased by the team, being used mainly by drivers Massimo Sigala and Oscar Larrauri. The team would also add sponsorship from Jägermeister and Warsteiner. Running their first full seasons of the WSC and DRM with the 956s, Brun continue to improve their performances as the season progressed. The season opened with a fourth at the 1000 km Monza, followed by fourth and seventh places finishes at the 24 Hours of Le Mans, and third and fourth at the 1000 km Spa. The team would achieve their second victory ever at the 1000 km Imola, which was followed a week later by a victory at a DRM round at the Nürburgring, and then once more a month later at the same circuit for an Interserie event. Brun would secure their first championship by winning the DRM teams title, while Stefan Bellof won the drivers' championship, having run for both Brun and Joest Racing.
