Toro Rosso found themselves at the wrong end of the grid during Friday's practice sessions at the Hungaroring.
Jean-Eric Vergne: "In the morning, I tried the car with the new updates the team has introduced this weekend. We had some doubts as to how it was working, so in the afternoon, we returned in some areas to our previous specification to do a check. Performance wise, we were definitely too slow today, so I expect we will need to make big changes on the car for tomorrow. I was overheating the rear tyres too much, which gave me a lot of understeer on the long runs and we were far from feeling comfortable today. A lot of work will be needed to make us more competitive for the rest of the weekend. The tyres are obviously very important in these conditions and we need to find out how to get the best out of them, as I was not very happy with their performance on both the long and the short runs."
Daniel Ricciardo: "We were optimistic at the start of the morning, because we had quite a few new developments on the car. However, we were unable to get the best out of them on track. We hope they will make the car quicker but it seems it is going to take a bit more study to get them producing their best results on track. We need to do more work on the set-up, but we have been in this situation before, so I expect that after a long debrief and more work this evening, we will be able to make progress in time for tomorrow. On the tyre front, we are seeing the usual difference between Option and Prime and in terms of the developments introduced by Pirelli, they appear to be working fine, which is positive."
Charles Pic: "For me FP1 was ok. I didn't have as much understeer as Giedo and from the start of the session had reasonable grip. In fact, we had too much grip at the rear for the first couple of runs but we improved that throughout the session.
"For FP2 we made a couple more setup changes and started with a better balance than we'd had in FP1. On the long runs the degradation was ok - it's there, more at the rear than the front, but it's not huge and for me it's manageable. We can take quite a few positives from today, particularly the gap to our nearest rivals and the long run pace which is again comparable to Williams, I think we could have a good weekend ahead."
Giedo van der Garde: "Both sessions today were all about understeer. In FP1 we ran a different setup to Charles' car to give us a baseline comparison and we tried some new brake material. To be honest neither the setup nor the new brake material really worked and we had to spend most of the FP1 trying to dial out the understeer. We also had a lot of front locking, something we didn't have last week in Silverstone, so we made a few changes to deal with that.
"In the afternoon the balance was a bit better but we still had the same understeer issues, and on the long runs we were seeing high degradation and graining on the front left. However, by the last long run the tyres were working better and I felt like we'd made some good progress. We'll work on all everything tonight and even though we have a lot of work ahead of us I'm pretty positive we can have a decent qualifying and race here in Hungary."
Jules Bianchi: "It has been a busy Friday for us but we are not where we want to be yet with the car. It feels like there is quite a lot more to find if we are going to be able to fight for a better position this weekend versus our direct competitors. We are also struggling with the tyre degradation, which is quite severe, so a lot for us to look at and consider with the engineers overnight."
Max Chilton: "It's good to be back on track at the Hungaroring, a place I have great memories of, especially after the win here in GP2 last year. It's been a short day for me, having missed FP1, so I had quite a busy afternoon session to cram everything in. We worked through the usual programme but the car is not quite there yet. I'm happy with my race pace but as I missed the morning session I didn't get to work on my ultimate pace. I also lost a little time on the soft tyre towards the end of the session after a big piece of rubber hit the visor screen on my car and broke it, which meant that I had to come in to have it replaced. We have quite a bit of work to do to try to extract more from the car so that will be something we'll be looking at carefully this evening."
