Following on from their strong showing in pre-season testing, Red Bull look to have put together the strongest package with their Honda engine having clearly made a big step forward, with the other Honda powered team Alpha Tauri also making a good step forward.
Qualifying confirmed Red Bull's superiority with Max Verstappen taking pole by nearly 0.4s from Hamilton, with Bottas third, a further couple of 1/10s adrift.

Some drivers may yet be penalised fro exceeding track limits in qualifying.
Notable performances outside the top three:
Perez for the wrong reasons as he failed to make Q3, when Red Bull need him mixing it up with the Mercedes.
Leclerc - had been behind Sainz for most of the weekend, but produced when required. However, both the Ferraris needed to use the softs to get to Q3, so could be disadvantaged by having to pit before most of the drivers around him.
Gasly - an excellent weekend so far in what is probably the most improved car on the grid.
McLaren - good qualifying in 6th & 7th, but might have been expected to be a bit closer to the front.
Vettel - struggled on his first outing for Aston Martin. He was pretty unlucky with two yellow flags on his last flying lap, which meant he only managed to finish 18th while Stroll made it to Q3.
HAAS - with two rookie drivers, it should be no real surprise to see them bring up the rear some way off the pace.
So, it looks as though Mercedes have their work cut out to claw back Red Bull's apparent advantage. However, as recent history has shown, they have a very good record of getting stronger as the season progresses. Say it quietly, but we could be in for the closest battle between two different teams since 2012.
