Bottas and Vettel were as fast as in their Q3 laps from last year. Hamilton a tenth down and Verstappen two tenths down. We don't know to which extent Mercedes and RBR were pushing, but we can be sure that Ferrari wasn't pushing so it's a good sign they managed to match the sector time of last year's qualifying.
Once they start performance runs next week, the important question to be adressed will be, how well the tyre temperatures will stay in the window in the last sector. This was the main issue last year.
