Malaysia Friday quotes: Renault

Nelson Piquet - 15th: "I did a lot of laps today and I was able to complete the planned programme which has really made a big difference. The fact that I know the circuit also helps and I have learned a lot and feel comfortable. I hope that things continue like this until Sunday as I was happy with the behaviour of the car. There is still a lot to do, but overall the result of this first day is most encouraging."

Pat Symonds, executive director of engineering: "Fernando experienced a gearbox problem and he was unable to use second gear, which is quite a penalty around Sepang. In view of the new gearbox regulations, we decided that, even though this was a test gearbox, we would leave it on and continue running to see what happened. Before the end of the session the gearbox failed completely. Nelson had a solid day learning the circuit, and his early performance was very good. However, our emphasis today was to develop both him and the car, and so we chose to use the tyres in a way that would give us optimum learning, as opposed to optimum lap times."

Denis Chevrier, head of engine track operations: "The first session went well for us, even if it was slightly shortened because of a red flag. In the second session Fernando had a problem with the gearbox, but we still managed to continue. Nelson had a busy programme, but we managed to complete it which is encouraging. As usual we should not place too much importance on the hierarchy that we saw today as this is only Friday. In terms of the engine, everything went well and we don't have any particular worries. We have recorded lots of information that we must now make the most of ahead of the qualifying session tomorrow."
