I decided on a vision. I think I maybe join Toyota at the midpoint of a project, whose long-term goal is winning world championships. Also I have my big ambition, the drivers' world championship. That is not abandoned - entirely the opposite. I am young enough and motivated enough to make a new start in order to reach this goal.

When you're very successful, you become careless and try to turn many things into routine.

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

In sport there is never any moment that is the same as the other. I have been in Formula One for 12 years, and out of that I had one year with the perfect car.

When you start out in a team, you have to get the teamwork going and then you get something back.

The switch from ten-cylinder to eight-cylinder engines means that each manufacturer has to redevelop its power train. Not all will manage to successfully combine performance with reliability the first time around. That could shake things up a bit when it comes team hierarchy.

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.
