US Friday quotes: Renault

Fernando Alonso - 9th: "This was a normal Friday for me. The grip levels are quite low at the moment, but that was the only major problem and the balance of the car feels OK. Friday is all about understanding the tyre behaviour and what direction you need to go in with set-up, which we have done. The circuit grip will improve as we run more, so the track should come to us a little bit, and I am confident for the rest of the weekend."

Pat Symonds, Executive Director of Engineering: "We had a useful Friday. When the cars began running, they already had a reasonable balance and the changes we made during the afternoon helped improve both the driveability and grip. We have begun to get a picture of the tyre behaviour, and there were no problems in any area. All in all, a good, solid start to the weekend."

Denis Chevrier, Head of Trackside Engine Operations: "As we have become used to seeing during the first half of the season, the amount of running we conduct on Friday is dictated by constraints of engine life and tyre usage. This is doubly true at Indianapolis, where the extended period of time spent at full throttle offers the engines a considerable challenge.

"So we ran a normal programme, finalising the mapping of Giancarlo's brand new V8 unit and Fernando's race-old engine, while the chassis engineers worked to tune the chassis behaviour. Everything ran smoothly, and we have collected our usual data for overnight analysis."
