As far as I'm concerned, I enjoy what I do, I enjoy the competition, working with a group of people to get the best out of them.

I was always fascinated by speed... My father was always an enthusiast and once I found a passion in racing, I had something in common with him, so from my childhood onwards we spent a lot of time going to karting tracks and racing in the various categories.

I was 25 when I stopped racing, I loved the teamwork and I wanted to apply what I knew about it into building and running a team.

We get paid based on where we are in the Constructors' Championship so therefore we want the fastest and best drivers we can get in the car.

We have a very good relationship with Renault. They treat us with absolute parity to the works team, and there is a very good collaboration between Renault engineers and Red Bull Racing engineers.

I think one thing Liberty finds frustrating is a lot of this business is conducted through the media. That's something they're not used to with American sport. There's that constant comparison of America sport and franchises verses Formula One - American sport works in America, it doesn't work globally.

You can window-dress and promote a movie as much as you like but if the movie hasn't got substance and isn't an exciting movie, people won't watch it.

I would put my money on both my drivers to win if it came down a streetfight.

The cap is a discussion about competitiveness, not about money. It's about trying to bring the top teams down to a level where the midfield teams feel they can compete. The reality is that whatever the level of spend there will always be teams that run at the front and teams that run at the back.

Times change, things move. F1 used to have customer cars years ago. You could buy a car from March or from Ferrari and go racing.

We need to think out of the box rather than just going round and round, beating ourselves up about numbers.

I have a long-term contract with the team and have said many times that there is only one Bernie Ecclestone. What he has done for Formula One is incredible and in my opinion he is irreplaceable.

I'd rather have a driver that was like that, that had that passion and that fire in his belly and you can channel that. The sport's crying out for more drivers like Max Verstappen.

A Hamilton-Vettel combination, on paper, would look very attractive to any team. However, what you have to look at is the dynamics of any partnership like that and it's difficult to see how two sportsmen at the absolute top of their game could work in harmony under one roof.

Just taking the front wing and saying that will make racing better, it's quite a naive and ultimately expensive approach.

I think if a driver commits to a team it's like disappearing with another girlfriend half way through the year, it doesn't seem like the right thing to do.

I would hate to see the championship decided on grid penalties.

It's so important to come up with the right specification of cars - they need to be loud, they need to be fast.

Red Bull is an energy drinks company operating a team in F1, of course it doesn't sit particularly well when you are competing against iconic brands like Ferrari and Mercedes. We are happy to be perceived as a bit of a maverick.

Red Bull have always been very good at nurturing young talent - Sebastian Vettel and Daniel Ricciardo are products of that - and it is important with Asian talent that people keep investing in it. There's a massive pool of people, for sure, and the next Sebastian Vettel is out there somewhere.

I have total admiration for the Renault guys in the garage that are working their socks off, week in, week out.

I think too often you see parts being taken from one engine to go onto another... That's been too much of a theme over the whole hybrid era, and that must compromise dyno time, that must compromise endurance running, and so on.

Exxon have done a very good job for us. Their difficulty and frustration has also been that as a customer we get very limited dyno time. But they were able to come up with a fuel that made the C-spec work, and we've managed to get that in the car and run that successfully, when the works team haven't been able to do that.

The most encouraging thing is that with the management changes there have been at Renault, they are very open to accepting that there are issues and they need to improve.

Nobody wants to lose Ferrari. And I don't think Ferrari can afford to lose Formula One.

Sport can change so quickly where confidence is such a big factor.

There are no ultimatums for Renault other than we want to improve as quickly as we can.

We want to run at the front, we want to be competitive and, in order to be competitive, we have to have a sensible power unit.

We want to be a works partner. Ferrari and Mercedes have their own works teams so where would you be in the pecking order if you're a customer?

Red Bull has invested a huge amount in youth and should be commended.

Obviously a decision was made to elevate both Jean-Eric Vergne and Daniel Ricciardo, who are two of the most exciting talents on the periphery of Formula 1, into race seats at Toro Rosso.

Red Bull doesn't get the credit it deserves. Neither Buemi nor Alguersuari would have progressed through the junior ranks - let's not forget Alguersuari won the British Formula Three championship - without the support.

Formula One is one of the biggest and most competitive sports in the world and our desire is to get back to be giving Mercedes a hard time and winning races and championships.

For Infiniti, the global coverage that Formula One provides is second only to the Olympics.

And I'd get back to the cars being physical challenges to drive - to tame the beast. The cars we have at the moment are fantastic bits of engineering, but it's a little too comfortable, a little too easy. I think I'd go back to making the driver a bigger variable.

When you're at the top you're always going to be shot at.

Race drivers are fiercely competitive animals, and there is often a conflict between what is right for the team and what is right for the individual.

You know, Theresa May, she's doing the best she can with not a great hand, a little bit like Chase Carey really.
