Germany preview quotes: Sauber

Kamui Kobayashi: "I know the Hockenheim circuit pretty well as I have raced there in Formula Renault, Formula 3 and GP2. I actually quite like the track. It has some narrow sections, but also a long straight and this combination makes it a very technical circuit. It is not easy to find the right set-up for the car there, and this is an interesting challenge. After two good races recently I hope we can keep our momentum and develop the car further. If the new update we will be getting for the German Grand Prix also works, as the last two did for Valencia and Silverstone, I'm confident of scoring points again."

Technical Director James Key: "After two good races we obviously want to carry on the momentum as best we can at Hockenheim. It's quite a different track to the last two. It's more a mix of slow speed corners in the final section, where you can gain lap time if you get it right, and to a certain extent quite a bit of straight line running. It's gonna be a tradeoff between downforce and drag. Braking stability will be important to get the best out of the slow speed corners. There are some high speed areas, which we think will suit our car well. "Most interestingly it's a circuit where you have one or two good overtaking opportunities. Tyre compounds are extreme, they are either very soft or very hard, so it will be interesting to see how that works out for qualifying and the race. This will increase the workload on Friday and Saturday to make sure we have a good understanding of both compounds. We will have several aero updates on our C29, including a modified diffuser. It's a package which is again a step in the same direction we've been pursuing for Valencia and Silverstone."
