Australia Friday quotes: Mercedes

Nico Rosberg, 10th: The first session was okay this morning and we learnt some good things. This afternoon was a bit frustrating with the weather interruptions but we were still able to learn a good amount on the tyres, which gives us some preparation for tomorrow. There are still some set-up issues to look at and improvements to make on the car, so we have plenty of work to do overnight.

Ross Brawn: It was a frustrating afternoon with the weather but we were able to get some good work done this morning. However, it's always very difficult to judge where you are on the first day. We made some progress on Michael's side and he was fairly happy with the car. Nico was not quite so happy and we may have gone the wrong way on some changes so there is still some work to do on the set-up of his car.

Norbert Haug: There were quite challenging circumstances for the teams and drivers in the second session with the frequently changing weather conditions. Nico was among the quickest in the first session and Michael in the second, but it is difficult to judge our performance compared to our competitors and we have to wait until tomorrow to find out what our results of today mean. All in all, it was a productive day and we should have a reasonable baseline for qualifying.
