San Marino Friday quotes: Williams

Mark Webber - 19th: "I had a few laps at the end of the session to help with the tyre selections - not as many laps as you might like, but I'll make up for it tomorrow. The balance feels about right and we have lots of good information from Alex to look through tonight."

Nico Rosberg - 17th: "I think today's sessions went well and Alex did a good job again to find the right set-up, so I immediately had quite a good balance when I first went out. We divided my activity in two runs so I had a bit of time to look at data comparisons. All in all, the performance felt quite good today."

Sam Michael, Technical Director: "We had a productive day with Alex's car today and we went through the whole programme, particularly checking tyres. The tyre choice will be difficult, but we have plenty of data to go through to assist the engineers with this. Alex also tried a couple of different mechanical set-ups specific to the Imola circuit. We did two runs with Nico's car to give him more track time and one run with Mark's car to check the balance, so it was normal activity for a Friday."

Simon Corbyn, Head of F1 Race Engineering, Cosworth Ltd: "All three CA2006 engines ran without problems today. As usual for Friday, Alex completed the bulk of the running and evaluated the effect of some engine map changes. The data will be checked tonight prior to finalising Mark & Nico's engine plans for Saturday & Sunday."
