There were top ten places in Friday's practice in Korea for Jenson Button and Adrian Sutil while Paul di Resta just missed out...
Jenson Button: "The circuit is always very tricky, particularly at the start of the weekend; I don't think it's used at any other time of the year so it's always very slippery in first practice. However, I think our afternoon session was a little more representative of our overall pace. We got some reasonable mileage under our belts and, even though I didn't get the best from the Supersoft tyre on my fastest lap, I think we've begun to understand the characteristics of each tyre pretty well. In terms of performance, I think we might be a little bit closer to the Lotuses than we've been for the last couple of races - but let's see what tomorrow brings. Also during FP2, my mechanics needed to effect a quick fix to a brake adjuster switch inside my cockpit - the lever was adjusting itself under braking, so we had to tape it still. It had a very minor impact on my running."
Sergio Perez: "We completed everything that was on our list for today - including getting some useful laps on high fuel, which was very important. We still have quite a lot of work to do to optimise the car's set-up when running the Prime on high fuel, and work to make the Option perform to its maximum on low fuel, so it's going to be a tricky balancing act - but we're looking forward to it. Overall, I think we're in a similar position to where we were at the last race in Singapore: if we can get into the points, it'll be a good result for us. The anticipated wet weather might help us out, too."
Adrian Sutil: "I really like this circuit and the conditions were ideal today for practice. We worked hard to find the ideal balance and in the morning there was more understeer, while in the afternoon there was more oversteer. So there is some work to do to this evening, but we seem to be in a good position for the weekend."
Paul di Resta: "It was quite a successful session and right from the first run I felt in the groove with the car. The long run pace looks promising and our tyre wear seems comparable to our rivals, which is a good sign. The area we need to improve is our one-lap pace so we will work hard tonight and hopefully find some gains ahead of final practice."
Esteban Gutierrez: "It was a very productive day. We've been trying different things on the car in order to adapt to the track. It's quite a challenge, because you have to compromise somewhere as the first sector has a high-speed character, while in the second and third sectors you need quite a lot of downforce. The track itself is really nice, even better than I expected it to be. It's fun to drive and has everything - fast, slow and medium speed corners. The first practice this morning gave me enough time to learn the track, and during the second session I was able to focus on the set-up and the balance of the car. Looking forward to qualifying tomorrow there is still room for improvement on the set-up."
Nico Hulkenberg: "We were quite happy with the car this morning and found a good rhythm. The session this afternoon was a bit compromised because of the traffic. I couldn't really get the first two runs together and, I think, there is still room for improvement on the option tyre. The car was performing quite well this morning, however, this afternoon it was a bit more difficult. We need to look into that now. I don't think we showed our best today, but I'm confident for the rest of the weekend."
Jean-Eric Vergne: "We had a problematic Friday, with the main difficulty having to do with the balance of the car. We are not too sure what is the cause of these problems, so it will be a long night to study the data to try and find a solution. Strangely, the car felt better in the morning session. We are not happy with where we are now, but I still believe the car can be much better here, so we just need to put everything together in the right way and try again tomorrow morning."
Daniel Ricciardo: "Unfortunately we were on the back foot right from the first session, because the pace wasn't there. We really thought we could cure it for the second session, but that wasn't actually the case. However, I still believe this is a track that should suit us, but we are leaving it to the last minute to be competitive tomorrow. It would have been nice to have a good Friday session, so now we just have to work hard to turn things around."
