Rosberg made his F1 debut in 1978 for Theodore, followed by drives for other backmarker teams Wolf and Fittipaldi, before claimign the Williams drive in 1982. He went on to win the championship that year over turbo-powered opposition, and stayed with Williams until 1985. He drove his final Formula One season, 1986, as Alain Prost's teammate at McLaren.
After a brief retirement, Rosberg drove for Peugeot in the World Sportscar Championship in 1991. In 1992, he joined Mecedes' GTCC squad, and then in 1995 founded his own Opel-based GTCC team.
