BMW Sauber F1.07 - front-wing development 28 February 2007
At first sight the F1.07 hasn't altered much since launch, but looking at the front wing, there's a variety of small changes. The endplates (1) have lower entry edges, which curve inwards and connect to an additional upper profile. This reduces turbulence generated when the airflow hits the edge of the endplates. In addition, new small horizontal profiles (3) act as airflow splitters ahead of the front wheels, lessening turbulence from air impacting the wheels. Another interesting new feature is a slit (2) in the wing's main profile. This divides the flap in two, acting like a double flap to increase downforce, but - because the wing isn't split over its entire length - with less drag.
