Sauber: Nico is building up a good relationship with the engineers 6 February, 2013 Nico Hulkenberg Sauber C32 The Sauber F1 Team had a productive second day of testing. In the morning, when the track’s temperature was still cold, the team concentrated mainly on aerodynamic tests. Later in the morning and in the afternoon – in better track conditions – the engineers and Nico started with some basic set-up work, and then made some runs on heaviear fuel loads. The car ran without any technical problems all day. At the end the team did a fuel system check, and Nico ran out of fuel. Tom McCullough, Head of Track Engineering : “It was a very good day with Nico achieving all our goals. Nico is building up a good working relationship with the engineers, which is important. We continued our work on understanding the Pirelli tyres. Without doubt the temperatures will be different once we go racing, but we still got to understand them well. The car was, again, very reliable, which gives us a solid basis. Nico Hülkenberg : “For the second day in a row it was pretty successful. We went through a lot of test items and did a comparison of the compounds – soft, medium and hard – which was quite interesting. Otherwise I was able to continue my familiarisation with the car and I did some long runs. Like yesterday, it was a positive day.“ What comes next: This was the final day of testing for Nico in Jerez. Tomorrow and on Friday, Esteban Gutiérrez will take over.
