There were top ten times in Friday's practice for the British GP for Jenson Button, Kevin Magnussen and Jean-Eric Vergne...
Jenson Button: "It's fantastic to be out on the circuit for the first day of the Santander British Grand Prix. To be here on a sunny day, and with a full house, makes it even better, too. Our car felt okay today, but we're still trying to find the right balance in the high-speed sections. We're struggling with understeer, trying to get more front-end from the car. It's tough out there because it's so windy: this year's cars have less downforce than before, which makes the wings very important. When they're affected massively by the wind, it makes it difficult to get any productive back-to-back results during testing. It's proving tricky for us to get the Prime tyre up to temperature, too; as soon as we back off for a yellow flag or for traffic, we can't get it working again. It's very difficult. However, the Option tyre looks good and is able to last for a reasonably long time. Nevertheless, it's been a good day. Hopefully, we can put on a great show for all the fans this weekend."
Kevin Magnussen: "This is a great racetrack - nice and fast. I think our car would probably be more competitive on a slower track, but, so far, it's not been looking too bad - we're not looking any less competitive than we did in Austria last month. After today, it's still difficult to judge the pace of Williams, but we'll probably be fighting the Force Indias. We could be up for some points this weekend, so getting the maximum of the car will be very important. Today's sessions showed that the Prime is a very hard tyre to keep alive - it's quite easy for it to lose temperature. At the moment, it looks like the Option tyre is the better race tyre for us. I love driving here, and I'm looking forward to enjoying the rest of the weekend."
Jean-Eric Vergne: "Besides the incident towards the end of FP2, it was a good day. The performance on the short run is not where we want to be, but the long runs seem pretty good. If we can find out how we can go a little bit quicker on the short runs I think the rest of the weekend looks encouraging. It is not like last weekend in Austria where we looked very strong already on the Friday. So we have some work to do to find out how to go quicker. Hopefully tomorrow will go better than today."
Daniil Kvyat: "It was a normal Friday where we tried to work through our programme. Conditions out there were quite tricky. It was windy and the track slippery. Regarding the balance of the car, I wasn't completely satisfied today, so as usual, we will look at all the data tonight and find a way to improve for tomorrow."
Esteban Gutierrez: "Overall, it was a positive day and I think we are going in a good direction. We were working aggressively on the set-up characteristics; this is the way to find something new and to explore opportunities. In the morning we were struggling with some set-up changes, but we are trying to find a compromise. Moreover, we still need to find stability when braking. Tomorrow is qualifying, so we need to keep pushing"
Adrian Sutil: "I could not run very much today, as I had to sit out the first practice session. It was difficult to feel comfortable with the car during the afternoon session. The set-up was not ideal, and that's why the car did not react in a way we hoped for. We changed something, but didn't get the reaction we wanted. We need to analyse the data to understand what the issue was."
Pastor Maldonado: "The start of the weekend hasn't been easy as we suffered from a power unit issue this morning which meant that our first session was over very early. Everyone has done a fantastic job replacing it with a new unit and we were able to make good progress in the afternoon. There is plenty to work on with my engineers before tomorrow. I'm confident that we can get out more from the car so as always we will push as much as we can."
Romain Grosjean: "There's still work to be done and in some ways I was happier with the car in the morning. We tried quite a lot of different set-ups to improve the aerodynamic platform in the afternoon, coming back to something we had earlier in the year. We've still got quite a bit to go through in the debrief with some hard work ahead to understand where the gains can be made."
