Valtteri Bottas has been speaking about his ongoing battle with fellow Finn Kimi Raikkonen. The pair are fourth and fifth respectively in the standings - but have also got a bit physical on track at Russia and Mexico.

"There's no need to say anything," says Bottas after being asked if he's spoken to Kimi.

“Sebastian Vettel’s honest and earthy assessment of his own error-strewn performance at the last race in Mexico - he used a deprecatory swear word to describe his driving - caused a lot of interest when the German arrived here. 

"Vettel himself was non-plussed. ‘I don’t think I was very self-critical,’ he said. ‘I was just honest. Sometimes the team makes mistakes, sometimes I do. I don’t understand the avalanche because if I make a mistake it is wrong to blame something else if it’s not true.’

"His target here and in Abu Dhabi in a fortnight’s time, he said, was to try to wrest second place in the championship back from Mercedes driver Nico Rosberg.”    

The wires coming out of Sebastian Vettel's head explain the German's dominance in the early part of the decade - he's a robot.

Vettel is third in FP1 so far, 0.614 off Lewis Hamilton.

It's quiet on track while the engineers tinker and fiddle, with 50 minutes of FP1 remaining. That gives Felipe Massa a few moments to chat with his family.

Ayrton Senna's first win at home. Magic.

The excitement of racing in front of his compatriots might have got to Felipe Massa a tad.

He has a wobble across the Tarmac and complains about a lack of grip.

The next thing you know he's riding the kerb like a rodeo king. Settle down Felipe.

“And a similar story at McLaren. Jenson Button does a 1:16.563 and then 1:16.067 on his first two flying laps. Then Fernando Alonso does his first and pops in a 1:15.920. As is so often the case, Hamilton and Alonso right down to the limit on lap one, others needing a little more time. That’s what people mean when they talk about the ‘natural talent’ of those drivers."

Lewis Hamilton goes even quicker with a 1:14.451, just 0.021 seconds ahead of team-mate Nico Rosberg.

Sebastian Vettel and Daniel Ricciardo are in third and fourth.

“There’s a statement of intent. Nico Rosberg opens with a one minute 15.940 and then a 1:15.564. Then Hamilton bangs in a 1:15.102 on his first lap. He really means this one, the world champion."

A change at the top in terms of driver, but not in terms of team. Lewis Hamilton clocks a 1:15.102, two hundredths of a second quicker than Nico Rosberg.

This will probably prove a popular one.

Lewis Hamilton's heroics in the final corners secured him the world championship at the expense of hometown hero Felipe Massa, who won the race on the day.

We're getting some times in.

Max Verstappen has registered a 1:16.157, while Carlos Sainz has a 1:18.261.

And here comes Nico Rosberg...

1:15.940 - so no surprises that the German is quickest.

Here's the nose of Lewis Hamilton's Mercedes, complete with new fancy air duct.

This made me chuckle. Kimi Raikkonen's contraption to measure resistance could be interpreted as many different things. Possibly a device to prevent another collision with Valtteri Bottas?

We're getting a close look at Lewis Hamilton's car in the garage, which has a new fancy duct on the front. It will experiment with some airflow options.

Meanwhile, Felipe Massa is in the cockpit and ready to take to his home track. Big weekend for the Brazilian.

“Has Lewis Hamilton hit a little hump in the road in this otherwise brilliant season? Yes, he has won three of the last four races and clinched the title on the way, but Mercedes team-mate Nico Rosberg has been on pole for all of them.

"It has been a strange turnaround in form after Hamilton took 11 poles in the first 12 races and that run was the foundation of his championship success. Hamilton said he was not worried about it, that he did not see it as a run of form, just a series of separate situations.

"Rosberg added: ‘I don’t know if it’s a trend or isolated incidents.’ That’s in public, though. Both men will want pole for very different reasons this weekend.”

Kimi Raikkonen is one of the drivers on the track to get the action under way at Interlagos. He has what looks like a bunch of coat hangers attached to the back of his Ferrari - they're to measure air resistance, apparently.

We're live on the tellybox folks. Catch first practice on BBC Two or right here on the BBC Sport website.

It's one of the first races you look for on the calendar, isn't it?

The Brazil GP rarely fails to deliver. In fact, has it ever failed to deliver?

What are your best memories of the Brazil GP?

To get you started, let us remind you of this thriller in 2012, when Sebastian Vettel made it three titles on the bounce.

Keep an eye on the mercury folks. It could sizzle in Sao Paolo, and that could test the tyres.
