Belgian Grand Prix: Sauber preview quotes

Sergio Perez: "Spa-Francorchamps is quite a daunting track with a great history. It has its own character and circuits like that are difficult to find nowadays. I am very much looking forward to racing there again. I believe it is one of the favourites of any racing driver. It is also challenging, and it is good to start the second part of the season with it. I believe the fast circuit in the Ardennes will suit our car. We should get everything right there and make sure we start into a productive second part of the season. Last year I qualified ninth there, but retired in the race. In what will be my second Formula One Grand Prix in Spa I want to at least score points."

Giampaolo Dall'Ara, Head of Track Engineering: "For drivers as well as for engineers Spa-Francorchamps is quite a challenging track. The downforce level is lower than on most other tracks, which is due to the long full throttle sections as well as the layout of the corners, which are mainly high speed with only a few low speed ones. With regard to set-up, it's not an easy track, and it's also quite demanding on the tyres, which this time will be the two hardest compounds - medium and hard. This is a logical choice, because the surface is quite abrasive, and there's a lot of load on the tyres in the high speed sections. But then you have this unpredictable weather. In the morning the track is often damp, and the conditions can change very quickly, which you have to consider when preparing for the weekend as well as during the race, when you might have to adapt the strategy. We will obviously use the medium downforce wings, and there will be some minor modifications to the car in view of the configuration we are running. Overall, I think we can expect a strong weekend for our team."
