My vote goes to Lewis Hamilton if he has got his head together this year and cuts back on his promotions and mixing it with the celebrities then he is a force to be reckoned with. If his head is not in the right place then it has to go to Sebastian Vettel. he definitely is a class driver.
It is early days but the Red Bull car does not look as strong as in the previous 2 seasons. It might be a straight fight between Button and Hamilton in the McLaren's.
McLaren drivers are always the best. Lewis Hamilton and Jenson Button are sure to contend for the title this year.
