McLaren MP4-22 - new rear wing 11 June 2007

McLaren debuted this in Canada as part of the ongoing development of the MP4-22's aero package. The new wing features a completely flat main profile, designed for low to medium-downforce circuits, and the base of the central mounting pillars (yellow arrow) has been brought forward, the pillars now inclining at a greater rearward angle as a result. This has two benefits - firstly, it helps to stop turbulence upsetting the airflow directed towards the rear wing; secondly, it provides a greater degree of stiffness, preventing the wing flexing rearwards under heavier loads at high speed.
