McLaren MP4-20 - rear wing development 24 July 2005
A hugely modified design for Germany. The all-new main profile still bends upwards, but its profile is narrower and is connected to completely revised endplates, featuring three horizontal slits (1), as seen now on many cars. The front edge of the endplate bends slightly rearwards (2) and the rear-most corner of the wing sports a deep cut, to reduce the turbulence generated by air exiting the main profile. Finally, the flap of the wing features a central Gurney tab (3) to increase downforce.
