There were top ten times in practice for the Chinese GP for Jenson Button, Romain Grosjean and Daniil Kvyat...
Jenson Button: "In terms of driveability, I think we've improved the car in a number of areas since Bahrain. There are a few more things we can do overnight, and there are some positive steps we can take to move a little closer to the front. After all, two weeks ago, in Bahrain, we also struggled during our long runs in FP2, so perhaps we'll be better in the race here. Today, both my front tyres were graining - but then this place is very tough on front tyres, especially when you're in traffic. There are a few things we can do with the set-up to ease the graining - and there are also a few things we want to do that will improve the car's overall balance - so hopefully we'll get a clearer picture tomorrow of where we stand - if it stays dry."
Kevin Magnussen: "The first corner here is very tricky, and that's where you do the damage to the front tyres. I don't know why we're not as competitive as we've been in the previous races, but we have a lot of front tyre degradation - and we need to investigate why. In fact, I've never had this much front tyre graining - it's very difficult to deal with, so we'll adjust the set-up and my driving style to compensate. It's a new track for me, too, so I need to adapt to that. We'll try to solve things overnight - but, if it rains tomorrow, at least we won't have any front tyre graining! Let's hope we can improve things for the race."
Romain Grosjean: "Everything seemed to work a little better today. It was a good Friday for us overall, we managed to do plenty of laps and understand as much as we could about the E22. We also evaluated a reasonable number of different parts on the car and power unit settings. For tomorrow we will see what can be achieved and of course it would be wonderful to be able to qualify in the top ten."
Pastor Maldonado: "I was a little optimistic on the entry to the pits, and the run off is quite short, but that's how it is. It's a tricky part of the track and we've seen incidents there before. Now we need to look forward - we had a good FP1 and we tried different set-ups in the car and completely different philosophies so now we have more data to analyse and look at in preparation for tomorrow. The car is improving - the power unit seems to be better and more consistent - so we're making good progress. Our quali mode is better, which is something we are working on, so hopefully this weekend will be much better for us. Points are realistic, so we'll do our best to achieve that."
Daniil Kvyat: "It was a good Friday and it didn't take me long to learn the track. I found it quite straight forward and we were able to start work on our basic set-up straight away. We managed to get through our programme and collect a lot of data for us to study tonight. So hopefully we will find a good compromise for tomorrow."
Jean-Eric Vergne: "I think it was a normal Friday. Today we needed to work on the long runs, in which we look pretty good. After today's sessions we feel confident we can have a good car for Sunday. As for tomorrow, I think we still have some work to do. The weather forecast is clearly predicting rain so it's difficult to say what to expect."
Nico Hulkenberg: "It was quite a smooth day in terms of completing our programme and working through the job list. There is still work to do on the set-up and some things we can try to optimise the car ahead of tomorrow, but on the whole I'm satisfied with what we learnt today. The tyre work went okay and we have all the data that we need on the soft and the medium tyres to prepare for the rest of the weekend."
Sergio Perez: "I had an issue with the DRS this morning, but the afternoon was much better and we completed our lap target. The tyre work went to plan and, as we expected, the degradation was high on the soft tyre. I'm still not completely happy with the balance so there are some areas to work on overnight."
