BMW rocked Formula One on Wednesday by announcing its exit as a team and engine supplier at the end of 2009. The Munich carmaker's abrupt decision, after a dismal season on the track and with the industry in crisis, leaves the glamor sport with just four manufacturers - Fiat-owned Ferrari, McLaren's partners Mercedes, Renault and Toyota. However, three new teams are due to enter next year with others on standby. “The BMW Group will not continue its Formula One campaign after the end of the 2009 season,” the Munich carmaker said in a statement issued before a news conference at their company headquarters. “Resources freed up as a result are to be dedicated to the development of new drive technologies and projects in the field of sustainability. BMW will continue to be actively involved in other motorsports series.” Team boss Mario Theissen told reporters that the natural scenario would be for a partner to take over the team that BMW bought from its Swiss founder Peter Sauber in 2005. BMW's exit is the first prominent withdrawal from the series since Honda quit in December due to tough business conditions. That team was resurrected as Brawn GP, the current championship leader, which now use Mercedes engines. BMW's decision, taken at a board meeting only on Tuesday, came just as the teams were on the verge of signing a new commercial agreement that would have committed them to at least the end of 2012. It also follows a standoff between the governing International Automobile Federation (FIA) and eight of the teams that nearly led to a breakaway championship, plunging the sport into its biggest crisis in 60 years. “Of course, this was a difficult decision for us. But it's a resolute step in view of our company's strategic realignment,” said board of management chairman Norbert Reithofer. The departure ends the carmaker's hopes of winning a title with their own team. The carmaker decided in mid-2005 that supplying engines to former champion Williams was not enough and bought a majority stake in Swiss-based Sauber, renaming the team BMW-Sauber. It won its first race last season when Poland's Robert Kubica triumphed in Canada, and challenged for both titles. This season, however, it has scored just eight points in 10 races and is eighth overall. “It only took us three years to establish ourselves as a top team ... unfortunately, we were unable to meet expectations in the current season,” said Klaus Draeger, board member for development. BMW has not supplied engines to any other team and Draeger said it would not do that in future either. He could not rule out redundancies.
