Mercedes: We are very optimistic

Mercedes AMG Petronas wrapped up the third and final pre-season test of 2015 today at the Circuit de Barcelona-Catalunya, with Nico Rosberg at the wheel of the F1 W06 Hybrid.

Sunday's schedule consisted of setup evaluation work,with Nico emerged for his first run at precisely 09:00 CET, completing 70 laps before lunch and a further 78 after the lunch break

Nico Rosberg: "Today was a good day and, overall, that was a very interesting test here in Barcelona. We made some mechanical set up changes on the car which was very interesting to me. I also did a long run at the end today on the soft tyres which was okay. In Melbourne we will have the soft tyre and it will be a challenge to manage them well, so we need to look at that. After this test, though, we can be happy. The team did a fantastic job. Thanks to everybody, who was involved in the development of the car. We are very optimistic. Now, I look forward to flying to Australia and getting back to racing."
