BMW Sauber's official response to the 2009 regulations broke cover this morning in Valencia.

Kubica was the first to take the new set of wheels for a spin, with a quick installation lap at the Spanish track. The team intend to commence a full testing schedule later today.

We've seen early revisions of the F1.09 chassis running during pre-season testing already, and the bodywork unveiled today doesn't offer too many surprises. The front wing still looks like it will require heavy contouring before the season starts, while the rear is clean and functional.

No major changes on the livery front, either. The team are sticking with the tried and tested blue on white effect. There does appear to be a surprising lack of sponsorship on car at the moment, especially around the engine cover section.

As ever, we're keen to hear what you make of the latest creation to come out of Hinwil. Does it look like a multiple race winner, and can you see the team fighting for a championship in the F1.09?
