Brazil preview quotes: Williams

"It's fantastic for Formula One to have a three-way battle for the Championship going into the last race of the season, which is not a situation that happens very often. Personally, I hope Lewis manages to win because he deserves it."

Kazuki Nakajima: "I'm obviously feeling really excited about my first Formula One race. I've never driven at Interlagos before, so I've been doing lots of preparation work in the team's simulator at Grove. I've also ramped up my training in the gym to help me cope with the pressures on my neck because it's an anti-clockwise track.

"It looks like it's going to rain over the weekend, so the weather is going to make the whole process quite tricky. I'm trying not to put any pressure on myself though. I'm going to take it at my own pace, work through each session step by and step and, above all, just enjoy it."

Sam Michael, Technical Director: "Interlagos is a well laid-out track. It has a lot of gradient changes over the lap and two long straights which are crucial for overtaking. The performance of the car in the corners that precede the straights is the most important consideration when it comes to car set-up.

"Lying 750 metres above sea level, Sao Paulo has the lowest ambient pressures of any circuit that we race at. With pressures around 930mbar, we lose around eight percent of our normal downforce. Drag is also reduced by around eight percent, but so is engine power, so top speeds remain the same.

"The grid line-up is traditionally tight due to the low fuel penalty and short lap time. Coupled with a long pit lane, the strategy is a close call between a one and a two stop strategy so we will see a mix of both on race day. Bridgestone are bringing the Soft and Super Soft tyres to the race, but we may not get to use them as the forecast is currently predicting rain all weekend.

"As this is the last race of the 2007 season, we will be pushing hard to claim points in the constructors' championship. We have had two races in a row where we haven't scored points due to various circumstances, but we are aiming to change that in Brazil.

"Alex Wurz has retired and we thank him again for all his hard work in developing the FW29 and contributing to the constructors' points for AT&T Williams this year. He is a great guy to work with and we wish him well for the future. As a result of Alex's retirement, Kazuki will be in the car in Brazil making his Formula One debut. It's a big weekend for him as part of his next stage of development."
