Nico Rosberg:

Today was good; we were looking at the tyres for next year mainly. That was a useful experience, looking at a lot of the set up for the new tyres as it could be quite different. It's always interesting to test the car here in such great conditions so that worked well. It was great to get back into the car again today and to do as many laps as we did is positive. You can see we're already testing parts for 2015, so I'm already looking forward to it. I will go away and reflect on a great season for the team with this incredible car and aim to come back even stronger for next year.
