Malaysia Friday quotes: Renault

Fernando Alonso - 15th: "We tried not to do too many laps today as I wasn't feeling one hundred percent. It's a very demanding weekend in terms of the heat because we sweat so much, but it was important that we still got enough information

"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."
