Brawn: New car faces tough initiation

The nature of the Brazilian Grand Prix track, which is situated on a rolling hillside, means the new car will not be easy to set-up this weekend.

"The bumps make it a 3D track when it comes to setting up the car," said Brawn. "Last year we did not find a good solution and we struggled in the race. The car was a bit too stiff, especially when it rained, which is always a strong possibility around race time in Brazil. We learned a lot from last year's race, which means we should have a better idea of what to do this year."

Brawn added that he doesn't quite know what to expect from the track surface this weekend.

"Every year there seems to be work on the track surface to improve the bumps, but they never seem to be eliminated completely just the places changed. It's not until we run on Friday morning that we really know the kind of problems that can be facing us," he said.
