Williams expects improvement in Brazil

The team has endured a tough start to the season with its troublesome FW25 chassis, but drivers Juan Pablo Montoya and Ralf Schumacher believe the car will be better suited to the Interlagos circuit.

"We've done well over the last two years at Interlagos so hopefully we can produce another good result this year," said Montoya. "It seems to be a track that suits our package. My intention is to try and make up for the victory that slipped through my hands in 2001, but I expect this will be quite difficult to do."

Schumacher struggled in qualifying at the Malaysian Grand Prix, although he recovered to finish fourth. "Sao Paulo's circuit should suit out package better," he said. "The narrow infield should work well with the FW25 and I am therefore very confident. I know first of all I must improve in qualifying, because managing to get the best possible set up of my car in a very short time has always been one of my strengths."

Williams chief operations engineer, Sam Michael, said: "Interlagos will be an exciting race for everybody as the track layout provides a couple of overtaking opportunities every lap. The circuit is dominated by slow to medium speed corners and straights. We are confident of a strong challenge in Brazil with improvements from testing on all fronts including chassis, tyres and engine."
