Bernhard Mühlner built his first competition car as early as 1978. Together with his brother Hartmut, he built a Volkswagen Golf GTI with which the brothers then competed in national rallies.
His involvement with the sport continued when in 1983 he started a wholesale & retail business for car accessories and parts, supplying a large number of teams and drivers with specialist parts for race and rally cars. Furthermore, teams and drivers in various championships were supported, up to and including the DTM and the ETCC.
1989 saw the formation of Mühlner Motorsport GmbH, in which Bernhard Mühlner, as team manager and race engineer, was responsible for all the technical side of things. Numerous race wins and podiums followed and four championships were won with race cars built, developed and run by the Mühlner Motorsport Team

After 12 years allegiance to OPEL, the period December 2001 up to the 2004 season saw Mühlner build a total of four VOLVO S60s for the German Endurance Championship and the Nürburgring 24hrs.

At the end of the season, the two 997s were converted for use in the Endurance Championship on the Nürburgring Nordschleife. Immediate success followed with a Group H win on their debut there. At the first running of the 24hrs of Bahrain in December, the team were able to celebrate a further podium with a second place after having been delayed by an accident and subsequent repairs.
