BMW Sauber F1.08 - cockpit winglets 20 July 2008
Like Honda, BMW Sauber have introduced in Germany a couple of horizontal rectangular winglets on the top edge of the F1.08's chassis (red arrow) just in front of the cockpit. These work in conjunction with BMW's distinctive delta winglets further down the nosecone. The air passing over the car from the front wing normally flows at an angle of approximately 30 degrees, but the new elements redirect this flow at a more horizontal angle to help improve the rear-end aerodynamics. This in turn improves the sharpness of the car's front end and the stability of the aero balance from front to rear.
