Among other updates, Sauber have introduced a brand new front wing design at Barcelona, with both drivers testing the wing during Friday practice sessions. The new wing appears to put the emphasis of creating downforce in the area just ahead of the front wheel, whereas the flap part closest to the car's centreline has less surface to allow a more clean airflow towards the sidepod inlets.
As ever, much performance is found in the front wing endplates, and as such the design has evolved in each and every detail. As a whole, the endplate is now a little higher above the ground, allowing more air to flow underneath. The trailing edge of the panel has changed as well, with the arrows marking the changes, including the addition of a small winglet, positioned at the highest and most rearward position allowed within the regulations.
