Spain preview quotes: Williams

"The atmosphere in Spain will be incredible because of Fernando, but it is good for the rest of us to compete when the event is buzzing. I'm looking forward to it."

Nico Rosberg: "Even though I have raced in Barcelona only once before in GP2, I know the track very well because we have done a lot of testing there, like most of the F1 teams. Since Imola, we have improved our performance and we were quite competitive at the Nurburgring, so I believe we can collect some points at Montmelo.

"It's an interesting and a quick track, and I like it. I scored some points there in GP2 and also set the fastest lap, but the best memory I have of Barcelona is my first test in an F1 car - a Williams, of course, back in 2002."

Sam Michael, Technical Director: "Barcelona is a unique circuit, but it is also challenging to find a well balanced set-up there. We spend some time testing at Barcelona during the winter but the weather conditions are usually so different that the teams are still tuning the set-up during the race weekend. The reduced engine power compared to last year means that two of the four high speed (250kph+) corners are now full throttle, although they still put a large loading on the car.

"We will have some mechanical items to further improve the FW28 as we go into the second race on the Cosworth engines, while Bridgestone are also bringing two new tyres that we have tested extensively at Barcelona and at Silverstone a few weeks ago. Strategy has traditionally been a two or three stopper, but the revised qualifying format may affect that, but that will become evident after the practice sessions."

Simon Corbyn, Head of F1 Race Engineering, Cosworth: "Both Cosworth CA2006 Series 4 engines will continue for their second events at this weekend's Spanish Grand Prix. We identified no problems with either engine during the post race checks at the Nurburgring. Cosworth will now work with WilliamsF1 to optimise the remaining engine duty cycle for both Mark and Nico in Barcelona."
