Turkey preview quotes: Williams

"I had a great holiday over the three week summer break with my family. I managed to train every day, and I covered lots of kilometres on the bike and while running. I also made sure I did some extra work to strengthen my neck, back and shoulders in preparation for Turkey."

Nico Rosberg: "Istanbul is a great track so I'm looking forward to driving it again. I'm hoping we will have found some more performance over the three week gap which will allow us to stay close to the others and to keep our momentum going into the last races.

"It's going to be very hot again so it'll be a tough race but it will still be easier than Hungary. I have some good memories from last year's race in Turkey, I was running in fifth at one point. To have a good race this year and score some more points for the team is what I'll be aiming for."

Sam Michael, Technical Director: "Turkey's Istanbul circuit has a great layout. It's a challenging track for the drivers and there are a couple of overtaking opportunities around each lap which make for good racing.

"During the three week break following the last race in Hungary, we've been working hard to deliver some more performance for the FW29 as we enter the final leg of the 2007 season.

"Downforce levels have to be fairly high in Turkey, not because the straights are long, but due to the many corners. The set-up will be geared towards medium speed cornering, while still allowing for the very long left hand corner that really loads up the Bridgestone Potenza tyres during the lap.

"We are expecting high ambient temperatures again this year, perhaps around 35?C, which, with no cloud cover, will raise track temperatures to around 50°C. Most teams will probably opt for a two stop strategy this weekend."
