I have always watched the Race of Champions on TV every year and dreamed about participating one day. It's fantastic to be invited; I'm so happy.

I remember my first test in F1. After five laps, I came back to the pits and tried to play it cool - 'Oh yeah, I'm fine, I'm on top of this' - but I was completely lost.

It's very shocking for me to see pictures from my win here in 2008. I aged.

I'm German but I didn't say that. I have no moustache.

Driving at high speed where safe and legal is part of my life. As well as a higher top speed I wanted even better stability in my FX and that meant work on the aerodynamics.

Generally I don't care about what people say. I have to be clear with myself. When everything goes well, people celebrate you, when you make mistakes people criticize you.

At the end of your life, it's friendships, emotions and thoughts that you take with you, rather than what's in your bank account. So, even though people don't have a lot here, they are a lot richer in many ways and we can learn from that.
