Mercedes GP determined to end season on a high in Brazil

The team has already secured fourth place in the standings and is fully focused on the development of next year's car.

But Brawn insists Mercedes is eager to finish the year on a high note at Interlagos after a series of positive results.

"Although our focus at the factory has been on 2012 for some time now, at the race track we are continuing to work hard with this year's car and make improvements," said Brawn.

"We are determined to end the season on a high and continue the run of top six results that we have enjoyed recently, which is the upper limit of the potential of the current car.

"Interlagos is a very unique track which presents some unusual challenges; the high altitude location, the bumpy surface and the challenging layout all test both the drivers and engineers."

Michael Schumacher is also looking to keep the team's momentum going after having managed solid results in the previews races.

"We have enjoyed some good results finishing in the top six over the last few races, and I would love to continue this trend in Brazil and bring the season to a positive end," said Schumacher.

"The team have worked very hard to improve our performance with the car that we have available to us and it would be a fitting reward for them."
