In the car and in front of the camera I tend to be very calm but behind the scenes I can get fired up and passionate, I just don't see the need to shout my mouth off in public.

I keep my weight low, although you need to be able to move your weight around the race car to change the balance. I'm 6ft and I'm 70kg so I haven't much fat on me.

I love cycling, running and swimming. In recent years I've competed regularly in triathlons, which means I don't find the physical side of driving a struggle any more.

To understand the intensity of driving an F1 car, you have to be in it. When you're driving a 750hp machine at 320km/h, the noise and the vibrations are incredible. The G-force when you take big corners is like someone trying to rip your head off. You hit the brakes, and it feels as if the skin is being pulled off your body.

I like old tunes when I'm driving. They're fun and uplifting. Billy Ocean, that kind of thing.

I don't purposely speed, but I might go over by five or six miles an hour from time to time. It doesn't give me a buzz driving on normal roads, because I can't go fast enough. It's never going to be anything like an F1 car.

Resting for me is fitness training.
