Sebastian Vettel: I felt very comfortable in the car today. The lap time in Q3 was good, unfortunately not good enough to beat Jenson – last minute he took the pole position away! But second on the grid, on the front row is great, especially as we were struggling a little bit with the car yesterday. The conditions are different to when we were testing here during the winter, but we fixed it and made a good recovery today. We also made an adjustment following this morning's practice, before qualifying, which seemed to work – so I'm very happy. We only needed one run on the hard tyre in Q1 and one run on the soft tyre in Q2. It was a great job and compliments to the whole crew for their hard work. Some parts arrived quite late, which has meant some long nights for the boys, but they will have some rest later today.

Mark Webber: That was a bit disappointing. I would like to have done a slightly better job in Q3 and I could have done it. Q2 was good, but that's not the most important session. We're fifth, so let's see what we can do from there tomorrow. Thanks to the guys at Red Bull, they've done another good job this weekend.

Christian Horner, Team Principal: A very exciting qualifying session – ultimately it was really tight between Jenson (Button) and Sebastian. We believe we have a good strategy for tomorrow so we wait with interest for the fuel levels, but the performance in Q1 and Q2 was extremely impressive. Mark's performance in particular in Q2 was very strong, which is also encouraging for tomorrow.

Fabrice Lom, Renault, Principal Engineer Track Support: It's a good result today and the car was very quick in Q1 and Q2. Now, we need to wait to get the weights of the cars to see if we are very happy or just happy! Tomorrow's race will be tough I think. There was a question mark over where the car would be with all the updates that we bought here, but we are still at the front so we can be positive for the rest of the season.
