Brazilian GP Sauber preview

Willy Rampf (Technical Director):
Interlagos is quite a different track to Melbourne and Malaysia, so it poses special challenges. There are two long straights: past the pits and along the back of the circuit. Then there is also the tight infield complex followed by the long climb to the start/finish line. It's quite difficult to strike the right compromise there, especially as you need very different set-ups for qualifying and for the race. For qualifying you need high downforce to handle the infield, but for the race you need high top speed so you can overtake on the straights. You also need to pay a lot of attention to mechanical set-up, with the springs and rollbars, to find the most suitable means of dealing with the circuit's serious bumps.

Nick Heidfeld (18 GPs, 3 World Championship points):
Team RED BULL SAUBER PETRONAS have shown so far that the car is competitive. I am definitely looking forward to racing at Interlagos. It's a different sort of track so it's difficult to predict how we will go. The weather is due to be as warm and sunny than in Australia and Malaysia, but the climate could also bring some rain.

Interlagos is interesting too for tyres as the track is reknown as to be bumpy. I also wish to find the quickest combination for qualifying. I kept my physical level up since the Petronas Malaysian Grand Prix as driving through the bumps is very uncomfortable: you get some very hard shocks on your whole body. Also usually muscles on the left of your neck are not as strong as on the right-hand side.

Kimi Räikkönen (2 GPs, 1 World Championship point):
Interlagos is another new circuit for me to learn. It doesn't worry me to know that it is anti-clockwise and considered as one of the toughest of the year in the calendar.

The track is difficult because it is very bumpy. It is a lot of work to find a special set up for that, unlike any other track in the F1 calendar. I'm looking forward to driving there, and to challenging again for some points.
