There were top ten times in Friday's practice in Spain for Adrian Sutil, Jean-Eric Vergne and Paul di Resta...
Adrian Sutil: "An interesting day with a big variation in weather conditions. It was useful to have the wet running this morning because it's an area where we need to be more competitive. The changes we made improved things with each run. The afternoon tyre work was normal, but we also ran on the prototype tyre, which was very hard and felt very different to drive. The normal hard and medium compounds are quite similar, but the difference between the two is bigger than I expected here. The long runs went well and the car felt pretty well balanced on the medium tyre."
Paul di Resta: "It was difficult to learn a massive amount today with the wet conditions this morning and our limited running. We had some new parts and both cars were slightly different to allow us to evaluate as much as possible. We will decide tonight the best overall package to carry forward. The baseline of the car is very similar to how it was in February during testing so we seem to be in the right operating window. My day was cut short with the tyre issue, but at this stage we're waiting for Pirelli to analyse exactly what happened."
Jean-Eric Vergne: "Earlier this week, I said I hoped we could have a positive weekend and that our updates would show signs of improvement and I have to say this is the best Friday we have had for many, many races. It's encouraging, but we still have work to do, analysing the data overnight, to try and improve still further. But we are looking in much better shape than in previous races: I am really happy, because everyone at the factory has done a very good job over the past few weeks to prepare for this race and the next ones after that. Tyres? All seems fine at the moment."
Daniel Ricciardo: "Overall, this was a pretty positive day and in the intermediate conditions in the morning, we were always in the top three or so, which looked quite good. Then, this afternoon we were also alright in the dry. I'm sure some of the teams, like McLaren will find more speed for tomorrow, but I think we can too. I expect it to be a close fight with a reasonable chance of getting into the top ten in qualifying and our long runs were also pretty good. It's always interesting to test new components and set-ups as you have to change your driving style a bit to deal with them. The best thing today was that the team brought a lot of parts here and, even if they might have looked good in the wind tunnel, it was reassuring to feel an improvement in the car on the track, where it matters."
Jenson Button: "As with any test of an upgrade package, there are positives and negatives to take away from today. There's now a better understanding of the correlation between the track and the wind tunnel. That's positive for the future, but of course we'd always like more. So I think we've moved forwards, but I think the others have too. We were limited in terms of the amount of running we could this morning, so there's a lot of data to sift through and plenty of things to change for tomorrow. We need to look at those elements that are potentially working and those that are not helping the overall car balance. We need to focus on a couple of areas - but, hopefully, we can improve them a bit by tomorrow."
Sergio Perez: "Today was basically all about the afternoon session, and collecting as much data as we could from some very intense running. It possibly wasn't the day we were hoping to have, but we collected a lot of data for the engineers - that's a positive. It was difficult to draw any clear conclusions from today, but the main positive we can take away is that we have a lot of data to feed into our simulation software in order to improve our understanding of the correlation. We've made a slight improvement. Once we get a better grip on our understanding of the correlation, I think we'll start making bigger steps. Over the next few races, hopefully we can make more progress."
Valtteri Bottas: "It was an interesting day for us. Unfortunately the weather wasn't quite right in the first session, but this was the same for everyone. We were trying different parts on the car today, particularly in the second session, so we have a lot of data to analyse tonight to work out the best set-up for tomorrow. The initial feeling is that we are starting to take steps forward."
Pastor Maldonado: "We've been working on different set-ups today and testing a number of new parts on each car. We feel a little more positive, but we will analyse everything we tested today and hope to show the improvements in qualifying tomorrow."
