Canada Sunday quotes: Renault

Vitaly Petrov - 17th: My race was almost over at the start when I spun. I was trying to overtake on the right hand side when I got pushed out onto the grass and lost the car, which put me at the back of the field. I was lucky that I only damaged the front wing, which we changed at the stop. Then I had the drive-through penalties, which dropped me further behind. So it's not really a race to remember for me, but it's still good experience because I finished the race and I learned a lot about the track, which will help me next year.

Eric Boullier, Team Principal: It was obviously a tough race for the team in terms of strategy and, particularly, tyre management. Robert had a good first lap and gained some positions, but he suffered high degradation in his first and second stints, and that ultimately allowed Rosberg to gain position on us. His points were very hard-earned. As for Vitaly, there is not too much to say - he jumped the start, had an incident at the start and was penalised for both. We changed his strategy and hoped for a Safety Car that would allow him to gain positions but, for once in Canada, it never came. This wasn't our best weekend of the year but we didn't lose much ground to Mercedes in the championship and the basic pace of the car during qualifying was strong. We will hope to bounce back strongly in Valencia.

Alan Permane, Chief Race Engineer: This afternoon's race was all about tyre degradation. We had hoped that our decision to qualify on the prime tyre with Robert would pay off, but we saw more degradation than expected in the first two stints, and that ultimately cost him position to Rosberg - even though we ran in front of him for much of the race. As for Vitaly, he had a character-building afternoon after receiving two drive-through penalties that put him out of contention early on. Although it's frustrating not to have made the most of the car's performance this weekend, the next circuit in Valencia should play to the strengths of our car, and we have more good developments in the pipeline.

Remi Taffin, Head of Engine Operations: It was a pretty difficult afternoon for the team. We were feeling optimistic after Robert made up places at the first corner, but then struggled to keep pace in the opening stints, which ultimately cost us a better finish. Even so, Robert finished seventh after starting eighth, so we cannot be too despondent. On the engine side, we had a trouble-free race and were able to push to the limit throughout. Now, we need to carry on working like we have done so far this year because we know we're heading in the right direction.
