Jarno Trulli – 6th:
Everything went well today and we did our usual Friday testing work. We had some rain in both sessions which makes things a bit harder than normal and particularly in the morning there wasn't much grip. But even though the weather disrupted things for us, we still went through quite a few set-up changes and it feels like we are moving in the right direction. The car seems pretty good on this track and I had no major problems so I hope we can continue this positive progress for the rest of the weekend. After the great result last time in Suzuka I am really motivated to keep up the momentum and I am optimistic we can do that.
Kamui Kobayashi – 13th:
It was a nice experience to be starting a weekend as a Grand Prix driver for the first time. It was also my first time driving in Brazil; I found that the track is good fun for a driver and also very challenging. Our work went well; just the weather wasn't perfect with the showers which meant the track surface was not consistent. That made it difficult to properly judge the set-up and also to fully learn each corner because the conditions were changing during the sessions. In the end I found a good rhythm and the car felt competitive so it was a good day for me. There are still things we can improve and I'll be working hard with my engineers to prepare properly for my first Formula 1 qualifying sessions. I'm really looking forward to it and I'm confident.
Dieter Gass, chief engineer race and test:
Overall it has been quite a good start to the weekend for us despite the difficult conditions all day. The drizzle in both sessions was not ideal but nevertheless we did pretty much all the work we wanted to; we just had to adapt the programme a bit to account for the weather. The two tyre compounds behaved largely as we expected, with no problems although the option proved to be a little better than we thought over a long run. Especially considering the difficult track conditions, Kamui's performance is even more impressive on a track he hadn't driven before today. We can only be pleased with how he performed. As usual we now have to look carefully at the data and fine-tune the set-up to get the most out of the car for the rest of the weekend.
