Formula One's (F1) youngest ever World Champion, Red Bull's Sebastian Vettel, has said that he doesn’t think he has changed that much since his title win. He said "although I may have the number 1 on my car, I will treat this season like any other, I will try my hardest [to win the title] and I don’t see why I shouldn’t succeed. The car seems quick this year, and I have had a good winter. I have no advantage by having the number 1 on my car, as Hamilton proved in 2009, but I will work hard and driver to my limits to defend my title"
