Mercedes appear in a league of their ownpublished at 15:38 Greenwich Mean Time 10 November 2017
Andrew Benson
BBC Sport’s chief F1 writer in BrazilLewis Hamilton headed team-mate Valtteri Bottas as Mercedes finished one-two in first practice.
Hamilton was 0.127 seconds ahead of the Finn, with Ferrari's Kimi Raikkonen a further 0.415secs behind and 0.006secs ahead of Red Bull's Max Verstappen. Red Bull's Daniel Ricciardo was fifth ahead of Ferrari's Sebastian Vettel.
On the evidence of first practice, Hamilton has a strong chance to continue his winning form - Mercedes appeared to be in a league of their own at this early stage.
Not backing offpublished at 15:31 Greenwich Mean Time 10 November 2017

Lewis Hamilton has won the title but has no desire to back off.
That certainly looked the case in first practice for the Brazilian Grand Prix.

A dominant display by Mercedes. More of the same in second practice? That kicks off at 16:00 so we will be back with build up from 15:30 BST.
I'll leave you with Andrew Benson's report and a few other things that are worth checking out below. See you in a bit!

Peter Wanyonyi: Poor, poor Brendon Hartley. He's got so much promise, but the car is <BEEP>. Imagine him in that Bottas Mercedes seat. Only reason I'm up at 2:30am NZ time is to watch Brendon!
Angus Hayward: I have a feeling that next season McClaren will be outrageously quick. Be a bit like Brawn and come out of nowhere to dominate. With the Honda engine which we know is incredibly slow they are getting closer and closer to the front.

Two minutes left and it looks like first practice will belong to Lewis Hamilton. His time of 1:09.202 is the one to beat...
Is Stroll good enough?published at 13:27 Greenwich Mean Time 10 November 2017
Andrew Benson
BBC Sport’s chief F1 writerStroll has had a couple of good races - Baku springs to mind when he was on the podium and Monza he impressed in qualifying in the wet.
Other than that, he's not been quick and youth isn't an excuse in my opinion.
If they come in and they're good enough, they're immediately quick, just like Hamilton, Vettel and Alonso were.
Unfortunately, I haven't seen any signs that Lance Stroll is going to be anywhere near that sort of level.

Max Verstappen, on his 13th lap on supersofts, is struggling for grip.
"How are the tyres, Max," he is asked.
"*BEEP*"
"Copy."
"I don't know why I just have no grip."

Andrew Benson
BBC Sport’s chief F1 writerWinning a junior category at Formula 3 or GP2 doesn't entitle you to a Formula 1 seat, and it doesn't necessarily mean that you're good enough to be a regular F1 driver.
I suppose you could argue they should at least be given a chance, but sometimes people who win things like GP2 prove to be not really good enough.

It's not been a good day at all for Toro Rosso so far because Pierre Gasly's car is currently up on the stands, lots of work going on underneath it.
Gasly has only managed five laps in the session.

Fancy a Brendon Hartley update?
"The team is still investigating the reason for the smoke coming from the exhaust, whether it's PU related or an issue from the oil sytem," say Toro Rosso.
"We have to wait until the end of the session for the car to be returned to the garage for further analysis."
