Spanish GP: Practice notes - Renault

NEWS STORY
20/05/2011

Both drivers tried Pirelli's new 'super hard' hard compound. It is very hard and quite a bit slower than the soft. Vitaly's car was slower without KERS in operation but today's problem will be rectified by tomorrow. Based on what we have seen today, it is increasingly competitive again, but Q3 and good points in the race are realistic targets this weekend.

Alan Permane, Chief Race Engineer: It was a reasonably routine Friday for us apart from running a slightly different programme to help us understand the new hard Pirelli tyre. We ran both drivers with high and low fuel loads on the hard tyres to get as much information as possible from this new compound. The KERS on Vitaly's car did not work today, but we're reasonably confident we can get to the bottom of the problem and have it working tomorrow. The hard tyre should allow fewer pit stops , but the soft is much quicker over one lap. Both drivers were reasonably happy with their cars today but I think there is more improvement to come from the car once we've been through the data.

Nick Heidfeld: "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."

Vitaly Petrov: "The good thing is we were able to test both sets of tyres for a number of laps, so we could take lots of useful data which is what today is for. On the other hand, I lost a lot of time because of not being able to use KERS to its full potential, so it was a little bit frustrating. This meant there was less power for my car, but the KERS also affects the braking so we had to work on the brake balance to compensate. I'm optimistic and looking forward to seeing what happens tomorrow."
