The 2009 F1 season

Give us your view on the 2009 Formula One season, which starts in Australia this weekend.

The 2009 Formula One season starts in Australia this weekend, with a shake-up at the head of the field promised on the back of new regulations. World Champion Lewis Hamilton looks set to embark on a difficult title defence as McLaren Mercedes struggle with the aerodynamics on their new car. Constructors' Champions Ferrari look to be there or thereabouts - Kimi Raikkonen needing to re-establish himself over team-mate Felipe Massa this year. Toyota, BMW Sauber, Red Bull, Renault and Williams have all set promising times during pre-season testing but the headlines have nevertheless been stolen by Brawn GP. The last team to appear on track - Honda's sale of the outfit only being confirmed at the start of the month - they immediately vaulted straight to the top of the timesheets. Drivers Jenson Button and Rubens Barrichello therefore have a very real chance of scoring success Down Under on Sunday. Do you think they can pull it off this weekend? Even if they can, surely it's the case that a season-long title assault is out of the question? And what of the rule changes themselves? Do you think new aerodynamics and the introduction of KERS will allow for more overtaking in 2009? Fill in the form below and give us YOUR VIEW on how you think events might unfold...
