Looking at F1 Tempo it doesn't look like Red Bull is faster on all other straights (like Hughes said), but it does look like they have slightly different lines. Verstappen going deeper on brakes, are they unable to take the kerbs?
I feel a lot of commentators err on the side of caution so it is easy to say Red Bull are fast, usually that is true.
Same with Formula1.com predictions where they predict Red Bull to be fractionally faster than McLaren in both race and qualy pace.
Should be fun to see tomorrow, if Red Bull doesn't take an easy pole I'd take that as a great sign for the remainder of the season.
