Autosport has the early picture of the BrawnGP (formerly Honda) car running at Silverstone. We can't tell much from the single picture put up, but the car does have an unusual low nose drooping over the front wing; Autosport describes the sidepods as "highly sculpted", although we are yet to see photos of the overall car for ourselves.
The car is due to run at Barcelona next week and we will probably get a better look at the car at that point.
