The 22 drivers have their say on Saturday's qualifying action in Korea where Sebastian Vettel took pole.
McLaren
Sergio Perez: "My fastest lap wasn't too bad - I had a small lock-up at Turn 15, but I don't think it cost me too much laptime. So, what we have is pretty much everything that we could have achieved today.
"We've developed a useful set-up for tomorrow afternoon, and we've also fitted a seventh gear that's long enough to hopefully enable us to do some overtaking. That means I'm looking forward to an exciting race.
"We really need to score some points tomorrow, and I think we're in a good position to do so."
Jenson Button: "On my fastest lap, I lost a tenth and a half behind Kimi [Raikkonen] in Turns 11 and 12. It's quite frustrating: they're pretty quick corners, and, when you're that close to the car in front, it damages your lap. It's difficult - because most of those corners are blind - but we've all got radios, so we should all know where other drivers are.
"It's a pity: without that delay, I'm pretty sure I would've qualified inside the top 10.
"Still, there are positives for tomorrow - we've got new tyres for the race; Turns One, Three and Four are always very interesting on the first lap; and we've got interesting straightline-speed compared to our rivals - both in terms of ratios and downforce levels - so the first couple of laps should be really interesting for us. Hopefully, we can go forwards tomorrow."
Lotus
Kimi Raikkonen: "I made a mistake on my only set of new tyres in the final qualifying session so my lap wasn't fast enough for a better position, which eventually meant I ended up tenth and will start from ninth position tomorrow.
"We've had a bit of understeer in the car so I've struggled a little all weekend. If you look at the long run pace yesterday we should have a stronger race, but obviously we have to see how the weather turns out. We hope to do better tomorrow."
Romain Grosjean: "Our aim was to be up there fighting with the Mercedes today and that's exactly where we were. The Red Bulls were always going to be quick, so to be reasonably close to them in terms of the times is not too bad. Gaining a place on the grid just because another driver has been penalised is not how you want to move forwards, but I've had to cope with it before myself and it's part of the sport.
"Of course, it will be an advantage for us as it means we'll start on the clean side of the track. Tomorrow will be interesting in terms of what effect the tyre degradation has, but our race pace looked strong yesterday so we're aiming for a good result."
Mercedes
Lewis Hamilton: "I'm really happy with second position today as it felt like I got everything out of the car today. The guys have done a great job to get the package as it is here: we came into the weekend knowing that Red Bull had an advantage, so to be as close as I am in terms of performance is a real positive. Hopefully we have closed the gap a little bit. Our long-run pace yesterday looked good and pretty close to theirs but there will be threats all around us in tomorrow's race.
"A couple of years ago, I was on pole and Seb got past me at the start, so I'd like to repay him on that one! I need to make sure we get a good start, position the car as well as possible and when there's a gap, I'll be going for it. We know that the weather will change a bit for tomorrow and I don't mind how it turns out. I'd prefer dry conditions but we'll see what the day brings and roll with it.
Nico Rosberg: "I haven't found the right car balance all weekend so far and that's the reason why I'm a bit disappointed with today's result - even if my actual starting position of fourth place is pretty good. The first sector of the track is good for overtaking, so hopefully that will give us some opportunities in the opening laps, but Red Bull still seems to have the edge here overall. If I get a good start like I managed in Singapore, then a podium finish is possible based on the performance we were able to show in the long runs on Friday."
Sauber
Nico Hulkenberg: "Today went really well. Q1 and Q2 were like clockwork and my lap in Q3 was good too, but somehow it was more difficult, I was four tenths down on my Q2 time and the grip was not the same as in the previous session. To start P7 tomorrow is very positive and we can look forward to the race.
"The car felt good during the long runs yesterday, and I feel confident we are able to hold our position tomorrow. It is so much fun driving here, however, we mustn't forget the cars in front of us are strong and also we have the McLarens behind us."
Esteban Gutierrez: "The communication was very good today, a big thank you to the entire team. I've improved my qualifying and once you have both cars working on a similar level you can push yourself a lot more. This is the first time I have driven here, so it is great to achieve a result like that. It is now the second time in a row I have been able to put in a good qualifying performance and that is a good feeling, because I have worked a lot to improve.
"The race will be interesting. The track temperature changed in Q3 and I had a bit of an issue with the balance of the car, and the front grip. Tomorrow will be similar to today, so we need to consider that in order to have a consistent race."
Force India
Adrian Sutil: "In the end I was very close to making Q3 - just one a half tenths away, so that shows how close things were today. We have been working very hard on the set-up all weekend and I was quite happy with the balance, but my lap was right on the limit.
"P14 still gives us the possibility to score points tomorrow, just as we did in Singapore. A lot of cars seem to have similar pace so maybe we need to try and do something different with the strategy to try and open us some options in the race."
Paul Di Resta: "The last few races have shown that our low-fuel running is where we are struggling at the moment. We were not fully optimised for qualifying because we've been focussing more on our race pace - as we did in Singapore. Hopefully that will pay off for us tomorrow because our long run performance and tyre wear yesterday appeared to be very good.
"So I think we've got a good race car, possibly better than some of the cars around us, and points will be the target. I will be starting on the cleaner side of the grid too, which always makes a big difference here, so if we can get a good launch we can hopefully be in a good position to make the strategy work."
Williams
Valtteri Bottas: "I drove a good lap but unfortunately we just didn't have the pace in the car to get us through to Q2, with the car lacking overall grip when I was pushing hard on my final run. Of course the team are disappointed with this result but I am fully focused to work hard with them to improve the car's performance ahead of the race tomorrow so that we can make up a good number of places."
Pastor Maldonado: "I struggled with traffic in my last sector which cost me some time on my final run, but we just didn't have the speed to get through to Q2 today and I was having trouble getting grip from the tyres. Our long run pace has looked better this weekend so that is a positive we can focus on ahead of the race, and I will be fighting hard tomorrow to improve our position."
Toro Rosso
Daniel Ricciardo: "I'm definitely not happy with my position and when the gap to the top ten is so small, you have to also be disappointed. I would have liked to have been in the car for the full hour. However, compared to where we were yesterday, we have managed to improve the car, but we have not been able to make enough progress to be more competitive than this.
"Now we have to look towards the race and maybe the only bright side of not getting into Q3 is that we have one more fresh set of the Supersoft tyres. Hopefully we can make good use of it and then we will see if we have enough pace to go looking for points."
Jean-Eric Vergne: "Since yesterday, we have struggled to set up the car the way we wanted, but hard work from the team meant that, this afternoon, at least the car was the best it has been so far this weekend. However, as the other teams also make progress, the improvement on our car for this afternoon was not enough to move us up the order.
"As for the race, we should be able to start each stint on new tyres and that could make some difference. I am usually optimistic, but I think points will be a difficult target tomorrow. I will give it my best shot and see if I can claw my way back up towards the top ten."
Caterham
Charles Pic: "We made some changes to the car overnight and the balance was better in FP3. At the start the car felt quite similar to FP1 - it was very much on the nose and it felt like we'd gone a bit too far forward on the aero balance, particularly in the medium and high speed corners so we changed the front wing flap angle for run two but it didn't really improve too much.
"The change increased understeer but didn't improve the car's stability so we made another mechanical change for the performance run and it immediately felt like the balance was better, particularly in the medium speed corners. We still had a bit of work to do before qualifying on improving the rear stability so we did that over lunch and started quali with a car that felt pretty well balanced.
"In quali we went for two runs on the supersofts, going out quite late into the session. The first run was ok but there was definitely time to be found which I managed to do on the second run, finishing up 19th and again clear of our nearest competitors.
"I did have a bit of traffic on the fast lap but even with that we wouldn't have been able to push the cars ahead too much so we start tomorrow about where we expected and with the car now feeling much better than Friday I'm looking forward to the race."
Giedo van der Garde: "Friday had gone pretty well for us and the car felt similar on Saturday. We'd made a few changes overnight and had maybe introduced a bit too much oversteer at the start of FP3, particularly in sector two, but overall it felt ok.
"We didn't make any big changes for run two as I was pretty happy with the car and then went onto the supersofts for the normal performance run at the end of the session and it was still ok. I made a bit of a mistake with the DRS in sector three on my fastest lap but I went into quali feeling positive.
"Quali was really close! The first run in Q1 was ok but we clearly had some time to make up - not enough to fight the Williams but definitely enough to put us back ahead of Bianchi and Chilton. In the end sector one wasn't as clean as we'd hoped for but the other two sectors were good and it was a very tight fight with my teammate.
"This time he just came out on top so we'll start the race behind the Williams cars - the aim is obviously to repeat what we did in Singapore and fight them as much as we can. We've shown recently that we have the race pace to do that so let's see what happens tomorrow."
Marussia
Jules Bianchi: "We seem to be doing a better job of sticking with the Caterhams now and although the gap was closer in this morning's Free Practice session, I hope we can have a better fight with them tomorrow, despite the setback of the grid penalty. We've done a good job of improving the car balance and we didn't get enough of an opportunity to really show that in qualifying, but I do feel more confident for the race now. "
Max Chilton: "I'm really pleased with the progress we've made with the car this weekend. I'm also really encouraged by my pace compared to Jules, which this afternoon was just over a tenth away. We obviously can't be sure yet what the weather will bring but based on the work we've done so far I'm quite happy and looking forward to 51 laps of the Korea International Circuit tomorrow in my first race here."
