I'm delighted to be coming back to Formula 1 after a two-year break, and I'm grateful to Lotus Renault GP for offering me this opportunity.

There's always a lot of talk about motivation to race, but nobody really knows what I do or what I think apart from myself, so I don't really care what people think.

Im winning races, Im still challenging for the world championships, the team is fantastic and I have a great relationship with everybody here - so why would I want to even consider changing?

When I was a kid, I would watch the grands prix. Everyone dreamt of becoming a race driver, while I only started thinking about it when I was 18 or 19. Only at that age did I seriously start thinking about this job. Before then, I would change ideas from one second to the next.

I'm happy, but there's nothing to jump around about.

Ha, some days ago the same people were one hundred per cent sure that I'd signed for Red Bull! So much for that.

When I did some NASKAR races this year I noticed that I was increasingly missing the racing side - to race against each other - because in rallying you really race against the clock.
