Brazil Friday quotes: Renault

Nelson Piquet - 7th: "I did lots of laps today, which was what I wanted as I needed to find the limits of the circuit. The initial information we have is interesting, but the track was very slippery today and so I think I can still find some more speed and I can still improve the set-up of the car with my engineers. But on the whole the result from this first day of practice is encouraging."

Pat Symonds, Executive Director of Engineering: "It was a typical Friday for us. We covered lots of laps and have been able to complete our usual programme, which included set-up work and tyre evaluation. The data looks encouraging, although the general balance of the car is not yet where we would like it to be."

Denis Chevrier, Head of Engine Track Operations: "We achieved our objective for today, which was to run as much as possible and to complete our technical programme. It's difficult to understand the pecking order from today's sessions, but we are satisfied with the work we've done and we're in a good position heading into the qualifying session tomorrow, which will determine the rest of our weekend."
