Stefano Domenicali, Ferrari (Team Principal):
“Overall, we are reasonably pleased with what we have seen today. The car seems to be competitive, although it has to be said that the Red Bulls were very strong. Now we must prepare as well as possible for qualifying and the race, with the aim of picking up a lot of points, continuing in the same vein as we began in Hockenheim.”

Chris Dyer, Ferrari (Head of Engineering):
“It was a very busy day because we had so many irons in the fire. This morning, we concentrated on development of new solutions for the forthcoming races, almost like an old-style test day and we also tried to evaluate carefully the performance of some aerodynamic updates which we brought here, as well as looking at the behaviour of the F10 with and without the blown rear wing. In the second session, we went back to the standard Friday programme, looking at defining the best set up of the car and tyre work. We completed both programmes with no particular problems, apart from a small electrical fault towards the end on Alonso's car, which prevented him from getting the most out of the long run on soft tyres. From what we have seen, the performance is reasonably good: we can expect a very close qualifying and we hope to be in the fight for the front rows.”

Alan Permane, Renault (Chief Race Engineer):
“It has been a very busy day for both cars – busier than normal because we have had a lot of parts to test and both drivers, car crews and engineers have done a very good job to get through the work load. Both drivers appear to be going well here, although they were running slightly different programmes today. It can often be quite dirty off the racing line at this circuit, but it was better than usual. The track was in good condition from the start of the day, although it certainly improved in the afternoon. We did a rear wing comparison with Vitaly and ran our floor upgrade with both cars. We also have a new front wing here and both cars will run with all these parts tomorrow. We didn't do a tyre comparison as such, but we did a lot of work with the super-soft tyre and ran it with high and low fuel to assess its qualifying and long run pace. Overall, it looks very good and we didn't find any problems.”

Martin Whitmarsh, McLaren-Mercedes (Team Principal):
“Today's programme was organised a little differently from our regular Friday sessions, as we undertook some shorter evaluative runs during P1 this morning. While we're encouraged by both drivers' feedback, and by the overall balance of the car, the pace of the front-runners was somewhat unexpected. Nevertheless, we've amassed plenty of useful data, and we're armed with a lot of information. As usual, we'll be working hard tonight in preparation for tomorrow's qualifying session, and we're confident of being able to make further improvements to our car. In a championship battle as tight as this year's, the crucial thing is to concentrate on having an error-free weekend and maintain strong consistency – even when faced with challenging circumstances. So that will be our aim for the remainder of this weekend. As ever, it's going to be a question of discipline, hard work and good racecraft, and that's what we'll be aiming to deliver.”

Patrick Head, Williams-Cosworth (Director of Engineering):
“Today was a normal Friday for us. Both tyres look stable, but it looks as if the softer tyre is reasonably faster than the prime. As Nico says, our work in P3 will be aimed at achieving top ten qualifying positions tomorrow afternoon.”

Ross Brawn, Mercedes (Team Principal):
“We had a busy day working with our revised aero package to find the right direction for qualifying and particularly the race. Both drivers completed some good set-up work but Nico and particularly Michael are not completely happy with our position at the end of today. We have a fairly clear picture of where we expect the prime and option tyres to be positioned for qualifying and the race but we have a lot of work ahead this evening to improve the cars for tomorrow.”

Norbert Haug, Mercedes (Mercedes-Benz Representative):
“Not a perfect first day of practice for us and there is certainly still work to be done tonight in order to improve the set-up of our cars. If the forecast is correct for tomorrow, there is a chance of thunderstorms around lunchtime which could possibly create an exiting qualifying session.”

James Key, BMW Sauber-Ferrari (Technical Director):
“It's been a very busy day. In the morning we tested some aerodynamic parts on both cars, which provided us with very useful data in view of future developments. The morning was okay for both drivers as the cars ran fine. The second session was more of a standard programme, looking at the set-up of the cars and the tyres. The biggest problems today were consistency and traffic. The grip levels were quite tricky and made it difficult to put together a good lap, particularly on the harder tyre, but also with the soft compound it was not easy to produce consistent lap times. That's definitely something we have to look into this evening. We've got work to do tonight, and I don't think it's straight forward, but Pedro being 11th on a compromised lap wasn't so bad. For Kamui we need to work on the rear end of his car to make it more stable. I think it's still open as to what will happen tomorrow.”

Laurent Mekies, Toro Rosso-Ferrari (Chief Engineer):
“We had a few new aero components to evaluate, some of which we had tested before and others that went straight on the car today. It's good that we got a full day of dry weather, given that there were a few showers in the surrounding area, as it helped our aero evaluation work. Apart from that it was the usual Friday work list: we evaluated the two types of tyre and they both performed very consistently. The rest of the time was spent on set-up work, with the usual trade off of very long runs, which we did with Jaime and single lap performance.”

Dominic Harlow, Force India-Mercedes (Chief Race Engineer):
“An interesting day here in Hungary as we learned a great deal about our exhaust blown diffuser with Adrian whilst Tonio concentrated on the tyre evaluations. Initial indications are positive. The circuit was in quite good shape at the start of the day and, as the temperatures increased the grip became a bit harder to find. We can improve the balance a bit more for tomorrow, and things are very tight in our area of the field so it's really a question of examining the data and going forward from there.”

Jody Egginton, Force India-Mercedes (Chief Engineer):
“Mixed fortunes today – with Jarno we completed today's tasks and put a lot of mileage on the option tyre, so we've got a lot of good data from that. Heikki was very unlucky to have a car problem which prevented him from putting in any decent time this afternoon – we tried to resolve it but the time beat us. Despite that we got a lot of valuable information from them both this morning, and more from Jarno this afternoon, so I think we'll be in pretty good shape tomorrow.”

Mike Gascoyne, Force India-Mercedes (Chief Technical Officer):
“A reasonable day although we had a hydraulic issue on Heikki's car which unfortunately limited his running in the second session. With Jarno we were able to complete the full programme, and the cars look like they are where we expect them to be and we have to make sure we have a reliable Saturday and Sunday.”

Nick Wirth, Virgin-Cosworth (Technical Director):
“A smooth day of information gathering for us. Both cars ran reliably, as we hoped, and we ran through a range of set-ups which we're deep into analysing at the moment. We're certainly not there yet on the set-up and both drivers had their best laps compromised heavily, so let's hope we make our usual solid set-up progress overnight and have a smooth Saturday.”

Colin Kolles, HRT-Cosworth (Team Principal):
“At the beginning of the first practice session, the grip level was expectably low. With one car, we did almost half a race distance this morning. Sakon did a very good job today and he was close to Bruno. We will be more competitive in qualifying and the race.”

Hirohide Hamashima, Bridgestone (Director of Motorsport Tyre Development):
“Once again we have seen very fast times from competitors, with the lap times faster than this time last year. The track surface started quite dirty, however not as dirty as we have seen in previous visits. Because of the dirty surface we saw front and rear graining, but no abrasion on the tread surface which we would sometimes see here. By the afternoon, the surface had improved greatly, and there was very little graining shown. Some competitors experienced a change in car balance when moving from the medium to the super soft tyre, so they still have work to do in refining their set-ups tomorrow.

“A lot will depend on the temperatures we saw here, as we have seen very high ambient and track temperatures in the past. If it is very hot, we expect less durability from the super soft tyre. If the track continues to improve as it has, and it does not get very hot, then we can expect very little in terms of degradation from the super soft. If this is the case, then this tyre will not only be the favoured tyre for qualifying, but also the better one for the race too. The medium provides good performance, however it is not as fast as the super soft. If this trend continues, a good strategy would be to minimise the use of the medium tyre in the race, so we could see different strategies relating to stint length than we have recently.”
