Toro Rosso joined Caterham, Marussia and HRT at the bottom of the timesheets for the final Friday practice of this season...
Daniel Ricciardo: "We must try and learn from today, but we have to bear in mind that the conditions could be very different when it really matters on Sunday. The two sessions could have been better, but hot conditions have not been the most suitable ones for us this year. All the same, we tried various different set-ups, splitting the work between me and Jev to learn as much as we could. It's going to be a long night trying to evaluate everything and then see what the weather does. In performance terms it would have been nice to do better, but in terms of knowledge I think we gained a lot. The 2013 tyres? They felt a little bit different, but nothing dramatic. Let's say we didn't find any negatives with them."
Jean-Eric Vergne: "I don't have much to say as we seemed to struggle a lot today to get the car working properly. That was mainly linked to the high temperature which did not suit us and made life hard for the tyres. We will have to work very hard tonight to come up with ways of improving the car for qualifying, even if we expect Sunday's race to be a wet one. Rain would definitely suit us better. We had some 2013 tyres to try and we had some sensors fitted this morning to see what they did. It's interesting to see for next year as the shape of the tyre is slightly different which will have an impact on the aero."
Vitaly Petrov: "I think we made some good progress in both sessions and I'm reasonably pleased with where we ended up. In the morning session we ran both the development tyre and the prime we have for this weekend and have a lot of very good data from both. We also tried a couple of different aero configurations which gives us options for this weekend, particularly bearing in mind the chance of bad weather on Sunday. In the afternoon we were looking at fine tuning the setup on long and short runs - we have more to do to get the best out of the harder of the two compounds but the car felt pretty good on the options and we can get even more out of them for the rest of the weekend. One thing that was immediately clear was how high tyre deg is going to be here. It's completely different to last week in Austin where one stop was the obvious choice - if it's dry here on Sunday it's much more likely to be two or three stops so tyre management is going to be key."
Heikki Kovalainen: "Having sat out FP1 I was back in the car for the afternoon session and it was important to get as much mileage completed as possible. We went through the usual program, focusing on tyre usage and setups on different fuel loads and I think it went ok. It's a shorter lap here in Brazil than quite a few of the other circuits, but our times looked ok relative to the cars around us and with some more work tonight and tomorrow we should be ok both for qualifying and the race on Sunday."
Timo Glock: "It has been a difficult start to the weekend to be honest. As usual it's all about the tyres and we are experiencing a bit of a different behaviour here again. We had quite a bit of oversteer in the car this morning, which was slightly better for FP2. However, at the end of the day we were still struggling with the balance of the car. Overall we concentrated more on race pace and didn't do much for qualifying yet, so we have some work to do tonight when we will try to improve the car and, I hope, make it a bit quicker."
Charles Pic: "The day started well for me as I completed some aerodynamic testing whilst acclimatising to one last new circuit for me. This afternoon we were focusing rather more on set-up work and the behaviour of the tyres in race-representative conditions. We were not able to get a good read of the option tyre and then unfortunately, towards the end of the session, I had to pull off the track as we experienced an alternator problem. I'm pleased with my long run pace but we have some more work to do to improve our qualifying pace."
Pedro de la Rosa: "This is an amazing circuit and really fun to drive. We found a good set up base from the beginning but it would have been better to do many more laps and long run simulations to fine-tune it in order to get a better use of the tyres. We have a lot of work to do mainly on the rear end because traction is still pretty poor. Today's times may not be quite representative, as we haven't worked on full loaded configuration but, on a positive note, the car worked very well on the medium tyres and I am confident that we can improve on the hard compound for tomorrow."
Narain Karthikeyan: "The circuit is exactly how I remembered it. It is very nice and flowing and there are a lot of nice corners, which makes it quite enjoyable to drive around. It was a difficult day because we couldn't do many laps and we didn't get the most out of the option tyres as I got a lot of traffic on my flying laps at the end of the session. I have to say that the car balance has been pretty good from the start and we managed to improve it slightly throughout the sessions. We certainly have room for improvement, though. Rear tyre degradation is still too high and we must improve traction so that's where we are going to mainly focus for tomorrow."
