Brawn GP Formula One Team, then the trading name of Brawn GP Limited, was a Formula One world championship-winning motor racing team and constructor, created by a management buyout of Honda Racing F1 Team led by Ross Brawn, but using a Mercedes engine.
The team only competed in the 2009 Formula One World Championship, with drivers Jenson Button and Rubens Barrichello. The team clinched that year's Constructors' Championship, and Button took the drivers' title. For 2010, the team again changed identity, becoming Mercedes GP.
On its racing debut, the season-opening 2009 Australian Grand Prix, the team took pole position and 2nd place in qualifying and went on to finish first and second in the race. Button won six of the first seven races of the season and on 18 October at the Brazilian Grand Prix, he secured the 2009 Drivers' Championship and the team won the Constructors' Championship. Barrichello won twice and finished third in the Drivers' Championship. The team won eight of the season's seventeen races, and by winning both titles in its only year of competition became the first to achieve a 100% championship success rate.
On 16 November 2009 it was confirmed that the team's engine supplier, Mercedes-Benz, in partnership with Aabar Investments had purchased a 75.1% stake in Brawn GP (Mercedes: 45.1%; Aabar: 30%), which was renamed Mercedes GP for the 2010 season.
