Motorsport: Lewis Hamilton insists he owes F1 nothing and does more than any driver in the world to promote it

World champion Lewis Hamilton insists he owes Formula 1 nothing after giving it everything for almost a decade.

The 31-year-old Briton told CNN he feels nobody has done more to promote the sport than him.

He said: "I've been here for 10 years - given my blood, sweat and tears for the sport. So, I don't feel like I owe it anything.

"I actually probably promote the sport more than any other driver ever has. I'm at more events talking about Formula One more than any driver ever has - probably all the other drivers put together and more.

"I don't feel like I have any more of a responsibility. I've got some incredible fans and I give as much time as I can to motivate them and energize those who do follow me. So I don't know what else I have to give."

Hamilton has won the world title three times but despite his standing in motorsport, he admits he has no say in how F1 is run - and doesn't want one either.

He added: "Ultimately sport, business... it's money and power. We [the drivers] will say stuff but ultimately it's those people who are sitting in their chair, striking a pen, paying checks, making money, that will be the ones that [have the final say].

"I'm not saying it's wrong. It's just like a corporate business -- money is the power, money is the ruler. The people who own the sport make the decisions. [Would I like to have more of a say?] Not really. It doesn't make any difference."
