Singapore Sunday quotes: Renault

Vitaly Petrov - 11th: I made a fantastic start and was running in 10th position early in the race. We stopped under the first Safety Car period and I was the first runner on prime tyres behind Webber, so things looked good. I need to look at the video to see what happened afterwards with Hülkenberg and why he pushed me out in turn seven, but his move cost me three positions. I was then stuck behind Massa, in the queue behind the Force India, and it just wasn't possible to overtake because we had all changed tyres at the same time. It was a tough race, but my luck went away from me yesterday in qualifying. I hope things will come back in my direction starting in Suzuka, so that I can put together a consistent weekend in qualifying and the race.

Eric Boullier, Team Principal: Overall, it's a disappointing and frustrating result because we scored very few points, while our nearest rivals Mercedes did a better job than us and stretched their lead today. Robert's puncture forced him to make an extra pit stop, and he drove superbly to fight back to seventh: it was the highlight of the race to see him make up six positions in nine laps. As for Vitaly, his race was compromised by a very ambitious manoeuvre from Hülkenberg, which cost him three places and some valuable points. We now must look forward to Suzuka and hope for a better level of performance across the weekend.

Alan Permane, Chief Race Engineer: It was a pretty exciting afternoon - but we'd have preferred a more boring race and more points. Our car didn't have the pace to stay with Rosberg today, and it was hard to do anything creative with the strategy when everybody was making just one stop. Robert was headed for a sixth- place finish before his puncture, and he then did an excellent job to climb back up the order. We stopped Vitaly under the first Safety Car on lap three, and he was in a very good position when he tangled with Hülkenberg. That cost him a guaranteed points finish.

Rémi Taffin, Head of Engine Operations: It was a tough race for both cars. Robert and Vitaly both made very competitive starts and were in good positions in the opening stages, but we ultimately lost ground to our main rival in the championship. For the engines, it was a very easy race: the temperatures were well under control, and we had no problems to push all the way through. It was the second race for both engines and, as per our plan, these units will not be raced again.
