Williams FW28 - side winglets / revised flap 23 June 2006
Some interesting aero changes for Montreal, aimed at increasing downforce on the circuit's twisty sections, without affecting top speed on the fast parts. Among them are these horizontal winglets at the top of the nose, not dissimilar to those on the Toyota and Renault. These reduce turbulence around the front upper wishbones, and clean up the airflow passing towards the rear of the car. The front wing also has a different profile to its top flap, which is now reduced in width in the central section to cut drag on the long main straight.
