On the last Friday of this year’s F1 season Ralf Schumacher and Juan Pablo Montoya had two troublefree practice sessions for the Brazilian Grand Prix.

Ralf Schumacher: The track seems to be massively bumpy. It is therefore not easy to find the right set-up nor will it be easy to make the right tyre choice. That said, all in all we had a trouble free day.

Juan Pablo Montoya: We did our homework today and the car seems to respond reasonably well. The track is maybe more bumpy than before, but the tyres seem to compensate for the bumps which is good. It won’t be easy to get the right balance and we have still quite a lot of work to do in view of tomorrow's qualifying.

Sam Michael (Technical Director, WilliamsF1): It was a normal Friday with our time spent on evaluating tyres and working on the set-up. Since we have not been to Brazil for a long time and the cars and tyres have evolved a lot we have more work to do here than perhaps on some other Fridays. The high altitude here means everybody is down on power but also on drag.

Mario Theissen (BMW Motorsport Director): It was a good practice day. Both the drivers completed their programmes methodically and without any problems. It is obviously not easy to find the ideal set- up on such a bumpy circuit. Regardless, we should have collected enough data to meet our tyre choice and both the engines ran without problems.
