#3 2009 Brazilian GP (Championship winner: Jenson Button)
2009 turned out to be the year of Brawn GP. Backed by F1 legend Ross Brawn, the team sensationally managed to dethrone the big boys in F1 and lead the pack thanks to their experienced drivers Jenson Button and Rubens Barrichello.
As we approached the end of the season, however, some cracks started developing in the Brawn arsenal and opened possibilities of a collapse. But thanks to the calm head of Button, the drama didn't last long.
Heading into Interlagos, Button had a 14-point lead but qualifying wasn't kind to him. What helped was that rival Vettel didn't do well either, and while Rubens Barrichello had every chance of winning the race and the title, he couldn't manage his way to the end. His race fell apart, and Button did enough to secure a famous maiden Championship.
