China Friday quotes: Williams

"We tried a few other things and really made good progress with the set-up. We still need to improve for tomorrow, but all in all we had a positive day and I have a good outlook for tomorrow."

Alex Wurz - 16th: "I only ran in the second session today and I started on used tyres to find my rhythm - which was not difficult, to be honest. However, the circuit conditions were quite strange today and I don't think the tyres were working properly yet.

"That said, it was the same for everyone, so we tried a few set-up changes in order to try and improve the car balance."

Kazuki Nakajima: "It was the first time for me on this circuit and even though it's not an easy track, I enjoyed it. The first long corner is fun, and it is then followed by plenty of corners with high lateral loads that make the tyres work hard. The track was quite green and dirty to start with, but it was okay at the end and we had a consistent run.

"We tried a few things for set-up and completed the programme. In summary, we had a good session this morning and I got a lot of laps under my belt, which was good both for my experience and for the team. The lap times we set at the end of the morning were reasonable, so I am quite happy with my work today."

Patrick Head, Director of Engineering: "We conducted a normal Friday programme with no mechanical problems and we are still working on how to generate performance from the tyres.

"Both tyres are very hard and so far we haven't been quicker on the option, but I am sure by tomorrow it will be the quicker tyre. We will be working hard to get the cars well prepared for qualifying tomorrow."
