US GP Friday quotes: Williams

Alex Wurz - 16th: "I just drove in second practice today on the used set of tyres from Kazuki's run in the morning. Just as I was starting to get into a rhythm and tune the car in, I had a gearbox oil leak. That lost us about half an hour so it was a real rush at the end to get some timed laps in. Despite the setback, we have a good idea as to the set-up we'll go for, we will just have to wait and see now how qualifying goes."

Kazuki Nakajima: "Throughout the morning session we worked on the car's balance and various different set-up options. It all went well and I'm particularly happy because I completed the programme as planned.

"This was my first time at Indy so going round the banking was pretty exciting, but then you get used to it and it becomes normal. It's a fairly challenging track, due to the twisty and slow speed sectors, but it's just a legendary circuit to drive."

Rod Nelson, Chief Operations Engineer: "A reasonably normal Friday morning. Kazuki was driving the T-car in the first session, as is normal when there isn't a GP2 race. He gave us some useful feedback on set-up direction and had a first look at the tyres. Nico, who drove in both sessions, did a good job looking at aero levels to gauge where to go for the race.

"We also carried out some mechanical set-up work, which we transferred over to Alex's car for session two. Unfortunately, Alex had a slightly more fraught session in the afternoon as we had a problem with a gearbox oil leak which limited our track time, but he did a good job with the little running he had."
