"I have done a few races and a lot of mileage.

"Esteban? We've had a good week. I met him a few weeks ago for our TPC test.

"We discussed a few ideas about how we felt about the car.

"I haven't got any position-based expectation. It would be impossible to say. We'll see where we stand in Australia."

New Mercedes driver Kimi Antonelli has just come into the media centre and done the rounds introducing himself to members of the pressure. 

A nice touch from the 18-year-old Italian ahead of his debut F1 season with Mercedes, having replaced seven-time world champion Lewis Hamilton. 

Jack Doohan is starting his rookie season at Alpine but there are already rumours he could be quickly replaced by Franco Colapinto, their new reserve signing.

Doohan was asked at The O2 today: "To be clear, you don’t feel undermined by Franco being there because it’s unusual to have a long-term contracted reserve driver at 21?"

Doohan replied: “Is that a question? I was a 21-year-old reserve driver last year with a long-term contract. 

"But, no, I don’t. Maybe I should. I don’t really understand the question. But, definitely not."

New Sauber driver Nico Hulkenberg said: "Those problems were mainly in the first quarter of last season. They worked through most of them last year.

"On the operational side, things were good, by the end. Car performance? That's a different subject.

"In Abu Dhabi, the car performance wasn't bad, wasn't far off what I was previously used to."

Sauber kick off the media debriefs for the day. We'll report all the big news stories here.

Passing through North Greenwich today? Well, you may bump into a familiar face!

There's a real buzz in the air today around this launch. 

Lewis Larkam reports that "there's already a few fans around this morning." 

Our F1 reporter Lewis Larkam is onsite at the O2 today and will be providing Crash readers with all of the latest from the launch event.

Today will be Lewis Hamilton's first public appearance as a Ferrari driver, having taken part in some private testing over the winter. 

The seven-time world champion's Ferrari switch and the hype it is generating is something that could be huge for motorsport this year.

Teams have already been revealing their cars in shakedown events over the past week, but all without their new colours. 

As such, the machinery you'll see on stage this evening at the O2 will be show cars.

Comedian Jack Whitehall will host F1 75 Live tonight.

Take That will also perform, and so will country singer Kane Brown.

Composer Brian Tyler's Are We Dreaming will also feature.

Machine Gun Kelly will also perform - yes, the same Machine Gun Kelly who had an awkward meeting with Martin Brundle on his grid walk, before taking to social media to compain.

We expect to hear from all 20 F1 drivers on stage at The O2 tonight.

We'll also see the liveries for all 10 cars.

We're in attendance all day at The O2 talking to the F1 drivers and their team bosses.

We'll bring you the latest news, the biggest bombshell quotes, and report the behind-the-scenes goings-on.

This page will bring you the latest live news, all day on Tuesday, until the F1 75 event culminates.
