Sebastian VettelSebastian Vettel is unfazed by suggestions that he is the favorite for this year's World Championship, but has made winning the title his clear target for 2010.

The 22-year-old German finished runner-up to Jenson Button last year and has been tipped as a favorite for the title this year, ahead of the Red Bull RB6's unveiling at Jerez today. When asked how he felt about heading into the season considered one of the top bets, Vettel said: "Happy, but I don't really care. Being favorite or not, I set my target for myself. I know what I want to achieve this year.

"Most important now is that the car is running and that we improve the reliability and speed. First you need to make your car work, then you see where you are and, according to that, you set your expectations.

"For sure, there is only one target, to be just one step better than last year. I want to win the World Championship. If we are the favorites, that's fine. If not, that's fine, too."

Vettel says that so early in the year it's not possible to know whether he can challenge for the title, or who his main rivals will be.

"First of all, we have to find out how good the cars are," he said. "Then you have a lot of good drivers in Formula 1, not only one or two, so we will find out who is fighting or who is falling in the position to fight for the championship.

"Obviously, I hope we are as strong as we were last year, or even stronger. Then you've got McLaren and Ferrari, who look very competitive already, and Mercedes with Michael. It's going to be an interesting season for you."
