Richard Rowland: George Abecassis born in Surrey co-founder of HWM . I think 2 races.

Excellent work by Richard here, who has found another British F1 driver called George.

George Abecassis entered two races - the 1951 and 1952 Swiss GPs, retiring from both.

Smokey, smokey.

A big puff of the white stuff spits out of the back of Brendon Hartley's Toro Rosso. It continues to stream out of it and he pulls over to the side of the track.

Lewis Hamilton has a bit of a cold this weekend, the legacy of a trip to Machu Picchu in the break between races.

He took 30 friends and family on a beach holiday first, and then went up to the famous Inca city in the clouds - and it lived up to its name when he arrived.

"We landed and it was miserable," he said. "When we landed we came through the darkest cloud I've ever seen and I was like, ‘What am I doing here?’. It was raining so much the first night, I was praying like 'please be clear tomorrow'. The next day it was clear and went up to Machu Picchu and it was beautiful. The next day I did the other mountain that's next to it, Winay Wayna, and that day it was raining and it was cold. I caught this cold. Otherwise I feel great - I just don't sound great.”

Interlagos is a trick little track because of those curves, so you've really got to use the corners and mistakes are punished.

It's great that George Russell has been given the opportunity, but this is a track that demands respect.

He's got to keep it clean, otherwise this could be an expensive morning.

Valtteri Bottas has emerged. He's got the soft tyre on his Mercedes and promptly goes quickest of all with a 1:10.820, a tenth of a second quicker than Max Verstappen, who did his time on the supersofts.

Lewis Hamilton heads out for the first time as a four-time world champion, leaving Valtteri Bottas as the only driver yet to make an appearance on the circuit.

Meanwhile, Max Verstappen gets the first time up on the board with a 1:11.491 in the Red Bull.

Is George Russell the frst-ever British F1 driver called George?

Don't forget you can listen to commentary on BBC Radio 5 live sports extra right now.

If you've just tuned in you've missed some Norwich-based chat. That's what wrapping up the title with two races to go does to people.

Busy track to kick things off with everyone apart from our new world champion and his Mercedes team-mate heading out in the first few minutes.

And 90 minutes of first practice is under way.

Also in for first practice is Charles Leclerc. He's in Pascal Wehrlein's Sauber and is also going out with the halo on his car.

There's a new kid on the block today as Britain's George Russell makes his Formula 1 debut by taking part in first practice for Force India.

Russell, who won this year's GP3 championship, steps in for Sergio Perez.

The 19-year-old will also drive in the opening practice session before the Abu Dhabi Grand Prix later this month.

So what do you think? Where does Lewis Hamilton rank among the F1 greats? And do you think he will surpass Michael Schumacher's record of 91 wins? He's currently on 62.

Can Lewis Hamilton threaten Michael Schumacher’s records for titles and wins, which once seemed impregnable?

“It depends, really,” says the world champion. I can continue winning for a long, long time. I guess ultimately it depends if the fight remains within you. Of course it is still there now. I still don't really have a desire to chase Michael, although I am obviously a lot closer than I ever was. I think before it felt so distant, getting 91 wins. But maybe now… It's still a long way off, but it's not impossible to think that I could potentially get somewhere near."

Four world titles at the age of 32. Assuming Lewis Hamilton fancies sticking around for a while then he has a real chance of retiring as the most successful F1 driver of all time.

But where does he rank alongside the greats? This has caused plenty of debate on social media, take a look at what 5 live commentator Jack Nicholls has to say in the video below.

Rusty Gray: Thank god you are here Gary. I almost had to do some work on a Friday for a second.

It's a lovely day in Brazil as we count down to first practice.

Lewis Hamilton has tied up the title but he still has plenty he wants to prove in these last two races of the season.

He says he does not like to dwell on the past, but his three consecutive losses to team-mate Nico Rosberg after clinching the title in 2015 still fester, and he said on Thursday: “I don’t want to be in that position again.”

There is also the matter of rubbing the noses of Ferrari and Sebastian Vettel in their implosion. “It is a better time than ever to apply even more pressure, just because you can,” Hamilton said.

Do these final races matter? You bet they do.
