Germany preview quotes: Sauber

Sergio Perez: "After being in Silverstone, the Nürburgring is another historical race track and, like in the UK, is in another country where I have lived. I am very much looking forward to going back to Germany and having a good race there. For me, after having missed two Grands Prix this year, it is very important now to push forward for the rest of the season and especially before the summer break, which is a very intense period with three races in one month. I also drove on the Nordschleife once in a road car. Obviously it is an amazing track. On the modern circuit one of my favourites is the chicane in the last sector, which I enjoy a lot. I also think the circuit should suit our car quite well and, summing it all up, we should have a good race there."

James Key, Technical Director: "The Nurburgring is quite a mixed circuit with different features, which makes it hard to characterise. Good braking stability is important into turn one, where there is a potential overtaking opportunity. The first sector is relatively low speed, or at least is after turn one which results in a car which needs good traction and good levels of downforce. Then there is a high speed section down to the hairpin, which presents another overtaking opportunity. The second half to the lap is relatively high speed. Primarily it consists of medium and slow speed corners and a couple of relatively long straights with a chicane in the end and a difficult last corner. This is a challenge for the engineers and drivers to try and get it right particularly in qualifying. It's going to be an interesting weekend, because there are many different challenges with the big mix of corners and straights. The tyre compounds will be medium and soft. We know the medium tyres were a little tricky in Canada, so we have to work on them. The softs should be okay. The car will continue with the updates we brought to Silverstone, which worked well, and we will have a further small update on the diffuser and the rear brake ducts. After our good performance in Silverstone, we look forward to carrying that momentum forward and trying to score more points in Germany."
