It was a good day for me in the changing conditions. What we lost in terms of planned dry weather programme, we gain in experience in the wet conditions in case the next days continue like this. This morning, on my side, we completed a few aerodynamic evaluations to progress our recent upgrade. I lost a little time early on because of a radio problem, but I was quite happy with the pace when I was able to start running. This afternoon we got to try both types of wet tyre but it was a little frustrating that the rain was so changeable because we couldn’t really get down to any detailed evaluations.

Unfortunately today did not pan out in the way we had expected in respect of the weather. I thought we would have more stable conditions. In general it was difficult again in terms of it being a mixed day. In FP1 I struggled quite a bit with the car for the same reasons as the early part of the Silverstone weekend, so fighting with instability, and unfortunately at the end we had a problem which cut the morning slightly short; not enough to make a difference thankfully. FP2 was wet again and we started out on full wets. The car was still very nervous and oversteering. I think we could have been quite a bit quicker but the instability issues make it a bit difficult at the moment. We have to look into that and I hope we find the problem overnight and see what we can do to improve tomorrow.

Whilst the rain came as no surprise to us today, what was a little more frustrating was the frequency with which the conditions changed from wet to drying to wet. Having said that, conditions like this on Sunday would make for a seriously interesting and eventful race for the fans and really test race engineers up and down the pit lane. In the slightly more favourable conditions this morning we achieved quite a lot of good work, whereas this afternoon has been more about evaluating the wet tyres at this circuit. All of this is useful however because none of the teams have any experience of the Pirelli tyres - wet or dry - at this circuit. We experienced an alternator problem for Timo at the end of FP1 this morning, but this was clearly attributable to parts mileage and readily addressed to ensure he is equipped for the rest of what is an important weekend for him in front of his home crowd. A good start to the day for Charles also on the other side of the garage.
