But he was hopeful the change would make him happier in the car.

And after first practice on Friday, he said that new chassis felt more natural to drive.

So he's very happy with the change.

However, Weber said years later in his book that Red Bull management had decided to tell Vettel his old chassis was cracked, even though it wasn't.

Webber said that team boss Christian Horner allowed Helmut Marko to deliver the news to Vettel to help him rationalise the fact he'd just been well and truly beaten by the old Aussie in the other car.

Webber said that in Vettel's mind, it was beyond comprehension that I could beat him fair and square.

There had to be another reason why.

And he said that Red Bull's decision to boost Vettel's confidence in this way said a lot about what was going on at the heart of the team.

John, what do you think of that?

If Vettel's original chassis was fine, is it still kind of OK for Red Bull to let him think there was a problem if they think that's going to kind of fix his head?

And as you say, that still goes on today.

I think that's fine.

If your driver's got into a kind of mental funk over something and you can at least give them that change and it makes them think there's been a reset, I think it makes sense.

It's, yeah, not the oldest trick in the book, but it's been around a long time.

I'm sure...

I'm sure Ross Brawn has told a story about either Ferrari or Mercedes did that to Michael Schumacher once.

And they just changed the chassis plate.

They didn't actually change the car.

Anyway, we'll come back to Red Bull later.

Someone who arrived in Turkey in really good form was Robert Kubica.
