As the trailing edge is pointing downwards, this element is not meant to produce any downforce but merely guide the air better towards the cockpit area. Practically, the first element of this ear is attached to the replaceable nose cone section, while the trailing element ... Read more

It appears as if this simpler wing generates less drag, a feature that is highly needed at both American circuits. We may expect the curvatious wings to reappear at Magny-Cours, France.

Mandatory slot gap spacers

While Ferrari and BMW were asked to strengthen their rear wings, some of the designs also feature a movable wing so that the slot gap between the two horizontal elements gets closed and hence makes the wing stall. In order to prevent these performance gains, the FIA mandated slot spacers that prevent the gap to be closed. It is for all teams a carbon element that connect to both the upper and lower element and makes t... Read more
