The BMW WilliamsF1 team took what Technical Director described as a risk strategy in running with a major upgrade of parts for the FW27 at the French Grand Prix. The team was faced with a limited amount of testing prior to running with the new parts at Magny-Cours. Given the poor performance of the cars at this race the team had underestimated the risk that they took.

When questioned about whether or not the team could see any improvement with the cars at Silverstone Michael explained what had happened and how the team was trying to improve the car for the British Grand Prix.

Michael said: "What we basically did is for Magny-Cours we had quite a big upgrade to the car, which basically is the whole package, and obviously with the limited testing there is now it is a very risky strategy. We did two days testing at Jerez, before Magny-Cours, and saw a couple of problems but I think we underestimated how big those problems were before we took it to France. And in the meantime we have had quite an extensive programme in the wind tunnel this week.

We have done a couple of things this afternoon which have started to give us some pretty good direction on where the problem is, whether we get to the bottom of it before the end of this weekend we don’t know yet, but we definitely started to make some improvements this afternoon.

A lot of our strategy this year, because we started off behind, was to throw a lot of bits at the car and a lot of it is untested, and I would say out of the majority of the time, 90 percent of the time, it works. This time it has bitten us. But we will pick it all up and make sure we sort it as soon as we can."
