Brazil preview quotes: Williams

"It was fantastic to see Fernando win at Suzuka but, knowing Michael and Ferrari, they will continue to push until the end. As with the last two events in China and Japan, weather could still play a role in sealing the Championship as the Brazilian Grand Prix is often wet on at least one of the days.

"There's always a fantastic atmosphere at the track, the Brazilians are so passionate about Formula One and will be right behind their home drivers. Interlagos is a very unique circuit, it's a very bumpy and short lap and I expect the qualifying times to be incredibly close."  

Nico Rosberg: "Brazil seems to be a great place. I was in Rio for the week prior to the race in order to get used to the time difference from China and Japan, and it is an awesome city. I learnt to surf there, which was really good fun. The Interlagos track is again completely new for me so I'm going to need to learn it fast.

"I will probably be at the track on Wednesday to have a close look at it with our engineers. Performance-wise, it's important that we build on the progress that we made in Japan and I hope that the Bridgestone tyres are as strong in Brazil as they were in Suzuka."

Sam Michael, Technical Director: "Interlagos is a great race track with plenty of overtaking opportunities, mainly created by the two straights and the variable gradients. Dominated by slow to medium corners and straight lines, it is important to have a good car balance in the corners that precede the straights.

"The long pitlane and low fuel penalty both have a first order affect on strategy decision and indeed what tyre compound level we will use. We worked with Bridgestone at last week's Jerez test to select two tyres that will cover the varying track temperatures that we can experience in Brazil. 

"This weekend's race, the final round of the Championship, will be significant for the team for two reasons. Firstly, it will be Mark's last before he leaves WilliamsF1. Mark has made a significant contribution over the past two seasons, not only on the race track, but he has also been a great team player and we wish him well for the future. It will also be Cosworth's last race with Williams, and we thank them for all their efforts this year.

"For everyone involved with the team, it would be a fitting reward to take some points away from the final round. It hasn't been the best of years for us, but we have taken all the lessons learnt on reliability and performance and are busy applying them to our 2007 car, where we aim to return to being a front running team."

Simon Corbyn, Head of F1 Race Engineering, Cosworth: "The 2006 Brazilian Grand Prix is likely to be the last race for Cosworth as a Formula One engine supplier. The objective from the outset of the CA2006 programme was to deliver the benchmark new generation V8 Formula One engine. Cosworth believe we achieved that in terms of engine performance, reliability and also engineering support to WilliamsF1.

"Mark Webber will start the weekend with a fresh Series 6 engine and will run an engine duty cycle specifically for Brazil which will allow the engine to run at 20,000RPM for the entire race. Cosworth will be going all out to add to our tally of 176 wins in 39 seasons of Formula One."
