Max Verstappen: "We had a good day today. The car was in a good window and of course we will try to fine tune a few things here and there but the short runs and long runs look good. The last two corners are better and more fun to drive, F1 cars feel much better at high speed. I tried to follow a few cars through there as well and it seemed okay, I'm positively surprised by the overtaking opportunities. I still need to look at the data and see how the other cars compare but today was a good day."

Sergio Perez: "We always try a lot of stuff in Barcelona, because it is always the most representative track we visit and really puts the whole season together. The new variation on the last two corners is quite tough on the neck, but obviously it was a very short day and I think we will feel it more on Sunday, it could be tricky on the muscles! Today was a good day, there is plenty of information for us to look at overnight. All in all I think there were lots of positives to take but we have to turn up a gear for Quali, as well as try to understand the tyres for the long run. This will be key for Sunday with the tyre degradation around this track."
