Brawn GP secured the 2009 FIA Formula One Constructors' Championship at the Brazilian Grand Prix in Interlagos today with Jenson Button driving a superb race from 14th position on the grid to a fifth place finish to wrap up the Drivers' Championship with one race of the season to go.

Teammate Rubens Barrichello started his home race from pole position after an excellent performance in Saturday's rain-delayed qualifying session but finished in eighth position after a late puncture forced an unscheduled trip to the pits and dropped him back to eighth place.

Brawn GP secured the Constructors' Championship with 161 points with Jenson winning the Drivers' Championship with 89 points and Rubens in third position with 72 points with the final race of the season in Abu Dhabi to take place on 1 November.

"What a day! I am so incredibly proud of the team and our drivers and it's so very special to have won the Constructors' and the Drivers' Championships in our first year as Brawn GP,” said an emotional Ross Brawn. “The second half of the year has been tough after such a successful start but getting the results in the difficult times is what counts in a Championship season. It's really going to take a while for what we have achieved today to sink in. Jenson is a fantastic racer and he had a great race today, particularly after such a difficult qualifying yesterday.”

“He knew what he had to do and did just that and is a very deserving World Champion. Rubens has made a fantastic contribution to this season without which we could not have won the Constructors' Championship today. The spirit in which our two drivers have fought for the Championship makes me very proud. They have been a credit to the team and our sport. The work and the commitment that the team showed over the winter and throughout this season really has been sensational.”

“We would like to take this opportunity to say our thanks to Mercedes-Benz who have been a fantastic partner for our team and have integrated incredibly well this season. Their contribution to our success, and the support of McLaren gave us over the winter and at beginning of season, has enabled us to be in the position that we are in today. I hope that everyone at the factory in Brackley and at Mercedes-Benz High Performance Engines in Brackley, is very proud of what we have achieved today. I also want to thank everyone who has worked with the team over the years that couldn't be with us this season as we had to resize the team at the start of the season. My sincere thanks go out to them because they worked so hard and should feel a part of our success."
