Sauber: We had some issues with the set-up of the car 19 February, 2013 Esteban Gutierrez Sauber C32 Today, the Formula One teams resumed testing on the Circuito de Cataluna near Barcelona. In the morning, Esteban Gutiérrez mainly concentrated on aero work, while in the afternoon he did tyre comparisons with the medium and the hard compounds, and he worked on the set-up of the car. He completed 68 laps. Tom McCullough, Head of Track Engineering: “We spent a lot of the morning evaluating some aerodynamic and mechanical parts on the car. We were also working on the hard and the medium tyres, but the track conditions were not ideal. We gathered a lot of data with some special instrumentation, and now we need to look at it. Due to a few small issues we weren’t able to complete our full programme, but we are confident we will be back on track tomorrow. Esteban Gutiérrez: “It was quite a tricky day with the tyres. We were struggling with tyre management and, as a result, degradation. We tried different things in the morning, but then in the afternoon we had some issues with the set-up of the car. The good thing is we have a lot of data to analyse. This will be the basis for us to understand everything.“ What comes next: Tomorrow, Nico Hülkenberg will take over from Esteban.
