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?

I just love the American spirit of racing. It feels just great to get involved with that.

Do you have any ambitions outside racing? My main ambition at the moment, whether inside or outside racing, is to become Formula 1 World Champion.

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.

Ive just got to do a good job and stay on in Formula One for as long as I can.

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.

You don’t drive races on paper.
