Nico Rosberg - 7th: "I think that the new aero parts we've brought out here are working as we expected them to, which is good. Having said that, levels of progress are always calculated in relation to other people and we are never sure where the others are, especially on a Friday. Today's sessions were mainly about tyre testing. We covered a lot of ground with them, particularly in the afternoon session, so we now have a better understanding of how both the option and prime are working, but we will have another look at them tomorrow morning to figure out how to get the most out of them. It's clear that tyre choice will be an interesting call for both qualifying and the race."
Kazuki Nakajima - 4th: "It was quite a strange practice day, especially the afternoon's session when we tried the prime and option tyre compares. The tyres really weren't working well today. I think our car is fairly quick, but we need to wait and check the data to see how we can get the best out of the tyres."
Sam Michael, Technical Director: "We had a reasonable day in terms of keeping to our schedule and completing the work that we needed to do. We've brought some new parts here, all of which are working well. Today proved useful in that we've collected some important set-up information which we will look at this evening in order to make the best decisions for tomorrow's qualifying and then Sunday's race. We then spent the majority of the afternoon looking at ways to extract the most from the two tyres that Bridgestone have brought here."
