Malaysia Friday quotes: Renault

"I hope what we have learnt today will be useful for tomorrow and allow us to work on improving the set-up. Hopefully I will recover more this evening and feel better tomorrow so that I can give my maximum in qualifying, which I think will be one of the most important parts of this weekend, so we need to be ready for that."

Nelson Piquet - 10th: "We had a good first day with no major problems and so things look a bit better than they did in Melbourne. There is still a lot of work to do, but I'm happy we improved the car between the two sessions. It will be a tough race with these temperatures, but I look forward to it."

Technical Debrief with Pat Symonds, Executive Director of Engineering

Track conditions: "The track was quite slippery this morning, probably due to the heavy rain yesterday."

Chassis balance: "The balance of the car is slightly better than we had in Australia, but we would still like to improve stability on the brakes."

Tyre performance: "The hard tyre here in Sepang has never been used before so it was a learning process for all of us, however the tyres seemed satisfactory."

Problems encountered: "Nelson went off this morning after a wheel failure and we are still investigating exactly what happened. Fernando's performance and programme today has been compromised by the fact that he isn't feeling well."
