Lewis Hamilton is complaining of cuts to his team on the radio. What Lewis is feeling on the straight is a hesitancy to the car. It doesn't affect your confidence though.

Robert MacPhee: Why has Hamilton done a seven lap stint in Q1 on dry tyres? I understand the logic when it is a wet qualifying but today..?
Daniel Eckersley: Alonso saying 'I have no power'. Tick that off your bingo cards, everybody.
The drivers out after Q1 are...
Disaster for Haas, and the Saubers were bumped out of it late on. Pierre Gasly did not get out of the garage.
Both Haas cars are currently in the bottom five.
Pascal Wehrlein is currently 15th and we could well have a Sauber advancing into Q2.

"If we get everything perfect there's a chance of the front row. It's close on times, it's a short lap and it's probably our best chance of a good grid position."

Ruairidh: The only time @LewisHamilton, external failed to finish in the top five this season was when he didn't get into Q3 at Monaco.
Great news for McLaren fans. Fernando Alonso fifth quickest so far as he continues to drain every second possible from his troubled car. Surely into Q2 for the Spaniard.
However, he does have a 20-place grid penalty to deal with, although encouraging signs for the race.

One of the reasons Ferrari and Max Verstappen are on the super soft tyres instead of the ultras is that they have fewer sets of the ultras. Mercedes have nine, Red Bull six and Ferrari seven. So if they can get through Q1 on the super softs it gives them more flexibility later on.
Who's in trouble at the moment?
The Haas duo of Kevin Magnussen and Romain Grosjean are, as are the Sauber pair of Marcus Ericsson and Pascal Wehrlein.

quixoticgeek: Has anyone checked that there's no Russian coins sat in the clutch on Gasly's car...
Daniil Kvyat looks to have been dropped by Toro Rosso, of course.
Now it's the Mercedes' turn and Lewis Hamilton takes the lead, slightly ahead of Valtteri Bottas. No dramas for the two leading teams in Q1.

RealityStrikes: Forget Lewis and the World Championship. Will Ocon and Perez come to blows?
The Ferraris of Sebastian Vettel and Kimi Raikkonen are first and second so far, and surely safely through into Q2. Both are well under that 1:19.00 predicted cut-off mark.

It's going to be brisk this Q1. Engineers think a 1:19.00 is needed to get through.

Mercedes are more nervous about this qualification session than any other this year.
They think if the temperature goes up it will benefit them, which is different to all the other tracks so far this year.
Image source, ReutersSo there will be only four other cars to miss out on advancing into Q2, with Pierre Gasly not recovering after his earlier engine drama at the very start of the practice session early on today.

Pierre Gasly has had a really torrid day. Just two laps in final practice before his car conked out and Toro Rosso haven't got him running.

This tweet from Mark Gallagher just shows the extent of Lewis Hamilton's dominance in the second half of the season.
He has won five of the last six races and come second (in Malaysia) in the other one.
