There were top ten times in Friday's practice in Bahrain for Jenson Button, Daniil Kvyat, Kevin Magnussen and Sergio Perez...
Jenson Button: "The conditions in the evening [FP2] were very different from the conditions in the afternoon [FP1]. There was no significant difference in terms of sighting braking points and apices under lights; no, the key difference was the lower air and track temperature. As you'd expect, on cooler asphalt, in FP2, it was much more difficult to get temperature into the tyres, but on the other hand you didn't have as much degradation, so there was a trade-off there. It was the same for everyone, of course, but there's still a gap between us and the fastest cars - in fact I don't think anyone is really happy with their car except Mercedes - so we've got a lot of work to do. But we're pushing as hard as we can to do that work and close that gap."
Kevin Magnussen: "Today we got through our planned programme well, and our car seems to be working okay on this circuit; it feels like a pretty decent racing car here, in fact, but obviously it's still too early to say much for sure. We're quite a bit off the pace of the quickest cars, of course, but I reckon we've got a slightly better chance to make up for that here owing to the cooler air and track temperatures. Also, apart from the quickest cars, the field seems to be pretty well bunched. If it stays like that, hopefully we'll have an opportunity to qualify decently tomorrow, which should place us well in terms of scoring points on Sunday. But it's early days yet, so let's wait and see."
Daniil Kvyat: "Overall, this has been a good day for us, as I managed to do a lot of laps, with no big problems. It was the first time I have driven under the floodlights and that was fine. Comparing the two tyres, clearly the Soft is much quicker than the Medium but in general this evening all the lap times were faster because of the big drop in temperatures once the sun went down. We will now analyze all the data with the engineers and I hope we can have a strong remaining weekend."
Jean-Eric Vergne: "It was not a bad Friday, even though we didn't start the day with a perfect car. Overall, we improved in the second session and I'm sure we can make the same step forward for tomorrow's FP3. We certainly need to analyse all the data carefully tonight, but I'm confident that there is still more speed to come, so this was an encouraging start."
Sergio Perez: "Today was positive; we managed to complete our programme and we're quite happy with the car, especially on the prime tyre. I was able to complete some long runs and that will give us plenty to analyse tonight. The track temperature and conditions change a lot between the late afternoon and the evening, and it's something we were expecting. We will keep working to improve the car for tomorrow, but we can be satisfied with the amount and quality of work done today."
Nico Hulkenberg: "It was quite a good day for us; we did not do a lot of running but when we were out on track the running we did was quite good. First practice was not that representative because the race will be held at a completely different time of the day and with very different conditions, but the second session was a more realistic. We did some quality running in this session and we looked okay. I felt quite comfortable in the car and we just need to do some tweaks to the set-up tonight. I think we have a good starting point for the rest of the weekend."
Adrian Sutil: "Today in the morning we were able to test different set-ups for the car, and that was ok. The medium and soft tyres are a good choice for this track. The second practice session was interesting because of the lower temperatures, which will probably be similar during qualifying tomorrow. In general, the grip was good. Because of the lower temperatures, the tyres are not over-heating, but the track is a challenge for the rear tyres. However, it is good that we have cooler temperatures, which should also be a benefit for the race. In the evening we could do our short runs with the medium and soft tyres. Later in the second practice session the engine switched off and I had to park the car in Turn 4. Because of this we missed doing the long runs. We tried to head out again, but there was no time left."
Esteban Gutierrez: " "Overall the balance of the car is pretty much there where we want it to be, and this is a good sign. The feeling of the car is quite good and I am satisfied with the balance. We still have some work to do with the gear shift. At the moment we are missing quite a lot of straight-line speed on high fuel. However, in the corners the car does not feel too far off. We have to work on the fine-tuning and we need to get a better understanding of the track temperature, as this is very different in comparison to how it was in Melbourne and Sepang. It is a different kind of warming up of the tyres."
