Malaysian GP: Renault Friday notes

RENAULT FRIDAY FREE PRACTICE

Jarno Trulli, 9th position:

"Quite a difficult day for us with set-up, and we worked all day to get the balance of the car right. We also worked on tyre choice, but a problem with my car during the afternoon session meant that we didn't get as much work done as we wanted to. The car felt good out on the track, but we need to continue working on the balance tomorrow."

Jenson Button, 8th position:

"We had a good day overall, and completed the programme we had planned. In comparison to the other teams, we are where we thought we would be, and now we hope to do a good job tomorrow in qualifying trim."

Pat Symonds, Executive Director of Engineering, Renault F1 Team UK:

"A useful day's work for both cars, although some of the results didn't turn out quite as we had expected. Unfortunately, a small problem on Jarno's car meant he didn't complete his programme, but we nevertheless gathered all the information we needed."

Denis Chevrier, Operations Manager, Renault F1 Team France:

"The A-spec engine includes some developments compared to the unit we used in Melbourne, and our aim today was to validate them in the high temperatures, as well as assessing the impact of the different cooling solutions and conducting our usual programme of engine optimisation. While Jenson managed a trouble-free day, Jarno experienced an engine problem during the afternoon which we must now investigate in order to assess its potential impact over the weekend."
