German GP practice quotes: Sauber

Esteban Gutierrez - 17th/16th: "I think it was a very productive day. We managed to run through the whole programme without any problems. We were trying different se- ups, which varied a lot, so it was tricky switching between the different ones. This was something we don't usually do, but at the end we gained valuable information. The day went well and it seems our performance in the long runs has improved. With all the data we gathered, I think we made a step forward."

Tom McCullough, Head of Track Engineering: "We had two dry sessions today, with both cars running reliably, so were able to complete our test programme. We continued with our extensive correlation programme gathering some useful data for the factory. The drivers were pretty happy with the car initially. We explored some different set-ups today. We still have some work to do on the low fuel pace, but the higher fuel long runs were pretty strong. Now we have to look at our data tonight to give ourselves the best car for FP3 tomorrow."
