Spain Friday quotes: Renault

Nick Heidfeld - 10th: "What was really interesting today were Pirelli's new super hard tyres. Although we've gained some experience of them occasionally on Fridays, we haven't used them a lot and they didn't really perform as I expected. They are significantly slower over one lap and during the long run too. That's the main difference between them and the previous hard tyres. The good thing is that I tried some out of the box things today, and attempted some different aspects to try and improve performance. We also managed to work on the set-up, which was useful. I think we've made some progress, but tonight we need to analyse exactly what we've learnt and where we can get even better going into P3 and Qualifying tomorrow."
