Jenson Button
Brawn GP dominated the early part of the 2009 season, with Jenson Button winning six of the first seven races. As other teams improved their cars, Brawn struggled for pace, but still recorded several podiums during the rest of the year. Their strong start and consistent finish was enough to secure the Constructors World Championship at the first (and only) attempt, as well as the drivers title with Jenson Button. At the end of the season, the team was purchased by engine supplier Mercedes-Benz.
