Brawn GP
In 2009, Ross Brawn's newly conceived Formula One team, Brawn GP used Mercedes engines to help win the constructors' championship, and Jenson Button to become drivers' champion. At the end of the season, Mercedes-Benz sold its 40% stake in McLaren to the McLaren Group and bought 70% of the Brawn GP team jointly with an Abu Dhabi-based investment consortium. Brawn GP was renamed Mercedes GP for the 2010 season and became the main team for Mercedes-Benz. The company continued providing engines to other teams under customer relationships.
