Sauber: New aero parts working well 8 February, 2012 Sergio Perez Feb.8 (Sauber) Today Sergio Pérez got his first taste of the new Sauber C31-Ferrari. He completed 68 laps. The pit crew had a busy day implementing some new aero parts and fixing a fuel system problem in the afternoon. Giampaolo Dall’Ara (Head of Track Engineering) “It was Sergio’s first day of testing with the new car. To start with he had to familiarise himself with the C31 and he did a bit of set-up work in the morning. During the lunch break we implemented new aero parts on the car. They are working well and as expected which is important and good news. In the afternoon we unfortunately lost track time because of a problem with the fuel system. So far we have only used the medium tyre compound.” Sergio Pérez: “For me it was a positive day. It was great to be back on track after the winter break and so far I’m happy with the new car. I feel confident. It was a shame that we lost track time due to the fuel system problem in the afternoon, but I think we can catch up tomorrow. We have a huge programme for Thursday and I’m looking forward to it very much. Compared to yesterday we have already learnt a great deal more about the C31.” What comes next Tomorrow Sergio Pérez will be driving again before handing over the car to Kamui on Friday.
