There were top ten times in Friday's Brazilian GP practice for Romain Grosjean and Paul di Resta while Nico Hulkenberg was 11th...
Romain Grosjean: "It was a very hot and sunny day which wasn't so easy for the tyres as it was difficult to get them to work properly so we struggled a little bit. Speed was not especially easy to find today, but we ran through our normal programme with a little bit of focus on a wet set-up as we know there's rain forecast for Sunday. We only ran a little with the 2013 tyres in the morning; my initial impression is that they feel a bit better and you can notice they have a different construction. Our long run pace was good so let's see what we can do tomorrow."
Kimi Raikkonen: "We had a problem in the morning but it's just one of those things; you don't want it to happen, but it's not the end of the world. It's unfortunate it took a while to fix as we missed time on track. Other than that, it was a very normal Friday for us. It was quite difficult to find a good set-up so we tried quite a few things. Tricky is usually the way for our Friday's and we've always been able to find a better set-up for Saturday so that's exactly what we'll try to do for tomorrow."
Paul di Resta: "I think we can feel quite positive about today. It was all pretty straightforward and the data looks quite encouraging. The hot conditions were tricky for everyone and the car was moving around quite a bit, but we've ended the day with a pretty sorted car that is working well in the low and high speed parts of the lap. I'm certainly feeling more confident with the car compared to recent races and I think we are looking reasonably competitive here."
Nico Hulkenberg: "You certainly felt the heat today and the car was quite loose and difficult to drive at times. Apart from that it was business as usual - doing the long runs and getting the tyre data. We also had an extra set of the 2013 tyres available this morning so it was interesting to get a taste for them and do a direct comparison with this year's tyres. It's difficult to judge where we stand at the moment, but we have all the information we need, so it's just a case of trying to understand things more tonight to be ready for tomorrow."
Bruno Senna: "It was quite a tough session today as we didn't get as much information as we would have liked for tomorrow. We've got some work to do to understand how we can do things better to make sure we're competitive for tomorrow, as the grid is very close here. It's very hot today but it was great to see all my home fans out there, even with sweat in my eyes!"
Pastor Maldonado: "The car felt good today; we were alternating the strategy between the two sessions, as we were trying different things, which meant we lost a bit of performance against this morning. However, I think we'll be competitive in qualifying tomorrow. We just need to work through the data to get the set-up right, but I feel confident heading into tomorrow."
Sergio Perez: "It was a good day in terms of getting done everything that was on the programme. We did a fair amount of work, but the heat just doesn't suit us. I found the car very difficult to drive this afternoon and I think some big changes are required. The difference between the two tyre compounds is really marginal. Let's see how we can improve."
Kamui Kobayashi: "We did a lot of set up work today and also tested some aerodynamic items. We had a busy day, but performance wise we are not good yet. Because of the high track temperatures the rear tyres overheated. The lap times were slower in the afternoon than in the morning. The rear is really weak and so far I don't know how to cool the tyres. We will now work on that."
