There were top ten times at the Circuit of the Americas for Bruno senna and Kamui Kobayashi while Kimi Raikkonen narrowly missed out...
Bruno Senna: "The track is really challenging so it was great to gets lots of running in today. It's very fast and flowing, and also a bit slippery at the moment but the grip is coming. It was a tough session as there is a lot to get used to with the car and the tyres. We need to keep pushing to try to understand the car better and improve to make sure we are in the points this weekend."
Pastor Maldonado: "The circuit is really nice and it was fun to drive. It was very slippery, particularly this morning on the hard tyres, but it's the same for everybody. We struggled a bit today with the car which we need to look at tonight in order to be ready for tomorrow."
Kamui Kobayashi: "The high speed corners of the new circuit are very enjoyable, I really like driving here. The first session was about getting familiar with the track and waiting for the tarmac to improve for a better grip level. In the beginning of the second session I did a 20-lap long run on hard tyres before we then had a break due to a broken exhaust. But the mechanics fixed the car quickly and I was able to go out on medium compound tyres as well. I must say I have big warm up problems with both compounds. It just doesn't work in qualifying if you need ten laps to get the tyres to work. We will now go and look for solutions."
Sergio Perez: "We had a good day in terms of getting all the programme done without any issues. The track is amazing, and I especially like the first sector a lot. I really believe we will see a great race here and I can't wait to race in front of so many Mexicans. Nevertheless I am not happy with the balance of my car yet, but I'm confident we will manage to improve it."
Kimi Raikkonen: "It's a nice circuit to drive; the sectors are quite different so there's a good challenge there. Of course, like with any new track there was no grip at the start of the day which doesn't give you a very good feeling, but as the grip improves it will be more fun to drive for sure. This morning was very slippery, this afternoon less so but you still can't really push and it's a bit tricky to find the limit. There's a lot of improvement to come - from the track surface and from the setup of the car - so qualifying will be pretty interesting."
Romain Grosjean: "The most noticeable thing about the circuit at this stage is the lack of grip; it's really, really slippery out there. The layout itself looks very nice but we're a long way off being able to push the car anywhere near the limit, particularly through Turns 7-9 and towards the end at Turn 19 where it's tricky to predict how the car will behave. The good thing is that the car felt comfortable on long runs with the hard tyre so we have a good starting point, but there is still a little bit of work to do with the mediums. We still have tomorrow morning and I think the track will continue to improve right until the end of the weekend, so qualifying will be interesting for sure."
Daniel Ricciardo: "The new track lived up to the expectations we had before coming here, although the lack of grip spoilt it a little bit. But as the track rubbers-in and cleans up, I'm sure it will get even better. The grip level did improve from morning to afternoon but I'd expected a bit more. In fact I reckon next year, we could find a completely different circuit, although by this Sunday I think it will be much more fun. The slippery conditions meant it was difficult to understand what our car was doing. We improved it from the first to the second session, but we need to keep on down doing that tomorrow. The tyres are taking a long time to warm up and that is one of the most complex aspects of the package that we must look at. It will definitely be an important factor tomorrow afternoon in qualifying."
Jean-Eric Vergne: "I have to say this is a really nice track and I like it very much. It is very challenging with a lot of places where you can overtake, even without DRS I can see some corners where you can pass, which will be good for the show and it is also excellent purely from a driving point of view. There was not one corner where I felt it wasn't interesting. Technically, it was quite a difficult day, because this morning there was no grip at all, but I'd say we maybe look a little bit better than at the previous grand prix. We saw some interesting things on the data today and I am sure we can have an okay day tomorrow."
