Abu Dhabi Friday quotes: Renault

Vitaly Petrov - 13th: "It was a difficult day for us today; it was difficult in terms of rear traction especially, and we are well off the pace. Overnight, we must look at how we can improve and get up to scratch. Something that was particularly evident was the drop in temperature between first and second practice. As a driver, every time you emerge from the garage for another run it is very interesting because the sun goes down and then by the final run it is dark. We really want to get better for tomorrow, take it up a gear and try to compete at a more consistent level than we did today."

Romain Grosjean: "I'm like a kid at Christmas at the moment. First of all, it was fantastic to get back into a F1 car and the feeling is just amazing. I tried to improve myself lap after lap. We tried some different things with the car and not to disturb the programme of the team, which is the main thing, and I think we picked up some ideas for the afternoon. The balance of the car was as we were expecting. We know that we're not fantastic on slow corners so we tried a few different things. The medium tyres were quite difficult to drive with, the prototype softs were better in terms of degradation, but it is always difficult to know what to expect when you go from one tyre to another. Hopefully my feedback can help a little bit for the rest of the weekend."
