Sauber: This was a far more positive day 22 February, 2012 Sergio Perez Feb.22 (Sauber) The team and Sergio Pérez had a much better day. The Mexican completed a good test programme at the Circuit de Catalunya, including a full tyre comparison of all compounds, as well as aero and set up work. For Thursday and Friday Kamui Kobayashi will take over at the wheel of the Sauber C31-Ferrari. Giampaolo Dall’Ara (Head of Track Engineering) “This was a far more positive day. Despite an exhaust problem in the late afternoon, we went through a good programme. Quite a few high priority points have been ticked off the job list. In the morning we started with aero comparisons, and then did some proper mechanical set up work. We also carried out a full comparison of all tyre compounds – super soft, soft, medium and hard – and ran different fuel loads. Of course it is not possible to really judge the car’s performance yet as we don’t know the other teams’ programmes, but today was productive and now we can work out the programme for tomorrow when Kamui takes over.” Sergio Pérez: “Today was a lot better, even though in the end we lost a bit of track time because of the exhaust problem. I am happy with how things went, we have gathered plenty of information to go through now and I believe we are working in the right direction. I hope we get some more work done with Kamui driving the next two days, and then we will be well prepared for next week’s final pre-season test session.” What comes next Kamui Kobayashi takes over on Thursday and Friday.
