BMW Sauber F1.08 - front wing development 19 October 2008

BMW Sauber have adopted a revised front wing assembly for the Japan and China races. The wing's main profile features a new lip, which protrudes to the rear. Visible thanks to its natural carbon fibre colour, this lip extends about 20mm under the flap entry edge (see yellow arrow and inset). Increasing the pressure of the airflow passing between the profile and the flap (and hence accelerating it), this modification helps enhance the efficiency of the entire barge board assembly, placed at both the level of the front suspension and in front of the sidepods. This slightly increases the level of downforce generated by the bottom of the car, without the team needing to adjust the angles of the flaps, and thus provides a more stable front end.
