Nick Heidfeld: After a reasonable start to the first session with some good adjustments to the car, unfortunately the changes we made for the second session didn't improve it. We tried to come back on some of those things towards the end of the afternoon and I did a fairly long run to get some information for the tyres. I'm sure that we can progress in time for tomorrow.

Timo Glock: In the first practice session we had problems with locking and too much understeer but we worked hard to find a slightly better compromise for the braking system which made things better. During the morning I damaged the front wing touching the kerb at the first corner, my mistake, and we lost a little bit of time as a result while the team repaired the car. My timed lap at the end wasn't too bad but minutes before the morning session finished I had a problem with the anti-stall system and the car stopped. The car was fairly good in the second session but then I damaged the front wing again. After that I was able to do some long runs which were quite good and I think we have found a good tyre. On the last run I think I could have gone three tenths faster if it hadn't been for traffic in the first sector.

Giorgio Pantano: This morning we had problems with rear locking but by the time the session ended we had understood what to do and changed something on the rear and on the brake side. In the second session the car improved quite a bit and I think we can probably get even better on the lap time.

James Robinson: We progressed through our usual free practice programme today working closely with Bridgestone who have worked very hard to bring a new tyre for us in Hockenheim. We were looking to get some distance on those tyres and get through important set-up work. We now need to see if the rain will come tomorrow and how we will deal with this for qualifying.
