Singapore preview quotes: Sauber

Sergio Perez: "I believe the Singapore city circuit could be a good one for us. Actually I have not raced there yet, but I did a lot of work in the simulator and, knowing our car, I really hope we can have a positive weekend there. We obviously need to score points to get back our sixth position in the World Championship. I have done some night racing in Qatar when I was in GP2. It is a very special feeling if you live at night and it can also be fun. I will arrive from Zurich, which means I come from the European time zone and then for the night race you actually just stick to that and don't go onto local time. Regarding the city of Singapore, I only had a quick look around during a stop-over, so I can't say much about it as this was only a few hours. This time I will make sure I come early enough to discover a bit more about it."

James Key, Technical Director: "Following Spa-Francorchamps and Monza, which are unique circuits, we go to another unique track in Singapore. It's a long and windy high downforce street circuit, which is typically quite bumpy. It needs good mechanical grip. Traction levels and braking stability are important as well. It's a hard circuit for the brakes. We'll be running a high downforce configuration, and we will be working on the mechanical grip. Pirelli will supply the soft and super soft tyres, the same as in Hungary, and we feel these are generally better tyres for us than what we have had at the last two events. We'll be looking closely at the balance of the car and its ability to absorb the kerbs and the bumps. We tested some new engine maps in Monza for the first time, and we will develop these further in Singapore. Even with DRS, overtaking will be difficult on this track, so qualifying positions and strategy are going to be important. Last year Kamui was able to make it into Q3. Obviously we are keen to bounce back after the disappointment of not scoring the points we thought were certain in Monza."
