Brazil preview quotes: Williams

Nico Rosberg: "Interlagos is a really fun track to drive as it has a bit of everything - gradient changes, a complete mix of corners and it runs in an anti-clockwise direction which presents a different challenge for the drivers. We had a strong race there last year and I finished fourth. As we haven't had a great showing in the past two races, it would be nice to do well again here and end the season on a positive note. It's going to be difficult with this year's harder tyres, and we'll have to cover a lot of ground with the car on Friday to get to the optimum set-up.

"After the long trip to Asia, I've spent the past week in New York training and spending time with my girlfriend who's over there working at the moment. As the Big Apple is in a similar time zone to Sao Paulo, and I'm now over any jet-lag after the trip to Asia, I'm in a good position going to Brazil later this week. It will be busy for me as I have several sponsor commitments to cover before the race weekend routines start, but I'm ready for the final round!"

Kazuki Nakajima: "This race marks my first anniversary in Formula One and I can't believe how quickly it's gone! I've certainly learnt a lot and I'll be using that experience in Brazil this weekend. This race will be easier than some of the others this season because I actually have experience of racing at Interlagos. Our car worked well in Brazil last year, and I hope that's the case on Sunday and we have a better race than we did in Japan and China. The track itself is fairly challenging, but it's really exciting to drive.

"I headed straight back to the UK after Shanghai so I've had the chance to spend some time at home and also to do some work with my engineers at the factory in preparation for this weekend's race. It was a busy time for me in Asia with lots of marketing commitments so the break was nice!"

Sam Michael, Technical Director, Williams F1: "Interlagos is positioned at a high altitude and has ambient air pressures around 930mbar which causes an 8% reduction in downforce, drag and engine power compared to when we race at circuits at sea level. The track's undulating layout consists of mainly slow speed corners, but it does have a couple of high speed turns that are taken at either full throttle, or just before braking for a slow speed corner, so their effect on lap time isn't significant.

"There are some good overtaking opportunities around the lap, particularly at turns one and four. The grid here is traditionally very tight due to the low fuel penalty and short lap time, so the midfield will probably be even closer than usual. Most teams will go for a one or two stop strategy and Bridgestone will supply the medium and soft tyre compounds, both options will be strong in the race. We've put in some good performances in Brazil over the years, last year's race being no exception. This weekend, we'll be looking to close 2008 with a good result."
