"The day has gone well. We have been able to complete our programme without any problems and we have recorded lots of interesting data. We still need to work hard to improve the car in time for tomorrow, but I'm pleased with my day."
"It might only be Friday, but it's important to get off to a good start on such an important weekend. We found a good set-up for the car, which seemed to be well balanced in both sessions. The track here offers a lot of grip and so, even with today's low temperatures, that was not a problem, especially given the tyres we have available to us here. My aim? To be in front of everyone, both tomorrow and on Sunday. Then we can do the maths when it's over. Racing at home, with the crowd on your side is a great motivation for me: it's a fantastic feeling, but difficult to put it into words."
“I was ill with the 'flu yesterday, so I took the time to rest in order to help me recover. Today I have been feeling better and I was able to drive with no problems. We had a good Friday session in general, going through the set-up work and looking at tyre choice for the race. We worked on balancing the car and we had some success.
“We still have some areas to improve, but in general I'm happy and we have shown a good level of competitiveness so far. It's only Friday and ideally we would like higher track temperatures, but all-in-all this has been a good day.”
"Our car was blindingly quick this morning despite the cold weather, which made the track feel quite slippery. This afternoon we focused on our race pace - but we were interrupted by the threat of rain and the changeable wind direction. I flat-spotted my tyres on a couple of runs, but I'm positive that the changes we've made will put us in a good position for tomorrow."
"It was a generally positive day for us, although it is still only Friday, which means it's too early to draw any definite conclusions. We worked through our usual programme and tried various settings on the car. The only difficulty was linked to the weather, with the rain coming down occasionally. My aim? To do my own race and help the team reach its objectives and I know what I have to do for that to happen. It will be a tough race on Sunday and you never know what could happen: we have to be prepared for every eventuality."
"We had a pretty productive day. I was happy with the car quite early on in the session as we got the balance right, which is always a good start. Getting on top of the tyres is not easy and we had quite changeable conditions, but overall that was a good start to the weekend."
"Free practice was mainly dry, but conditions were tricky in the drizzle – you would see the drops on your visor and wouldn't know how far you could go. We made a big step, improving the car from the morning to the afternoon.
“I think here it will be quite tricky to get the tyres working well over a long run, and you could see several people struggling with that. Towards the end, you could see the grooved tyres become slick tyres, so maybe we're already getting ready for 2009."
