McLaren MP4-21 - front-wing development 29 July 2006

An evolution in Germany, which in some ways seems to be going in the opposite direction to recent developments. The wing's endplate is completely different to that at the last race. Its profile is now vertical at the top as opposed to the bottom, with the bottom, not the top, sloping outwards. And the previous horizontal upper fin on the endplate is gone. This is because the new shape provides the effects of reduced turbulence and increased downforce previously supplied by the fin.
