BMW Sauber F1.07 v Ferrari F2007 - front wing comparison 20 October 2007

These two designs look visually quite different, but actually follow very similar concepts. The flaps sport a completely different profile on their rear edge (red arrows) but both have a vertical fin underneath (visible protruding from the rear of the flap) to divert airflow towards the sides. The additional upper profiles also have similar functions. The BMW's are noticeably shorter than the Ferrari's, but their more curved and sculpted shape manages airflow in the same way. And finally, the central spoon profiles again appear different, but serve the same purpose. That on the F1.07 sports a sort of squared lip, whilst that on the F2007 has a steeper, sharper profile. Both manage airflow in this area, feeding the front barge boards at front-axle level.
