Everyone is replaceable, including me.

Psychologically speaking, it's very important to be in good shape. I work in a sport that requires you to react quickly and be in excellent shape. Besides, things don't get easier as you get older.

Your ups and downs in sports, I think they are as normal as daily life: One day you wake up and feel great, the next day you wake up and feel maybe less great.

I hate to take compromises with a racing car. The more standard a car is, the more compromises you have to take.

I'm not very comfortable with what people sometimes say or think about me - things I don't feel responsible for.

I think I was five when I had my real first go-kart.

I have what you might call the South Pole and the North Pole. I have my team and my work, which I do on one side, and I have my family and my home on the other side. Both have nothing really to do with each other.
