BMW Sauber was a Formula 1 team that competed in the seasons 2006 to 2009. The team was created when BMW stopped as an engine supplier for Williams. BMW then wanted to continue independently as an F1 team and therefore took over the Swiss Sauber team. Out of respect for the old Sauber team and founder Peter Sauber, the new team was called BMW Sauber. The team withdrew from Formula 1 after 2009.
