Paddy Lowe, Chief Technical Officer: In FP1 we ran several tests and experiments across the cars on both aerodynamics and brakes. In FP2 we conducted our normal programme of tyre evaluations on both low and high fuel, split across the drivers with the soft and supersoft tyre compounds. We had no issues and both drivers achieved what they set out to complete today. FP2 was more difficult for balance and pace due to the changing wind direction, so we lost some ground between sessions. However, we have a lot of fascinating data to study both tonight in order to make decisions for qualifying and the race, and to take back for further analysis for our ongoing development programme.

Lance Stroll: That was just another Friday, but the track conditions certainly changed a lot from FP1 to FP2. We will have a briefing now, go through everything and try and sort out a few issues and see what we can do for tomorrow. We have the usual stuff to do to try and find more lap time, but the car's performance was more or less as expected. We are where we are, and I will just drive as fast as I can. Anything can happen, and maybe a bit of rain will come up.

Sergey Sirotkin: It was a long, difficult day. I had predicted it would be tough. We still managed to go through some interesting things and we collected some reasonable data. Putting it all together, we would expect some progress for tomorrow, but at the same time we need to be realistic that what we put together isn't going to deliver an impressive step in performance. It's going to be hard tomorrow, but it is what it is.
