McLaren MP4-22 - horn winglets removed 03 August 2007
The famous horns were gone at the last round at the Nurburgring and remain absent in Hungary, though it is too early to say whether the change is definitive. What is clear is that the new 'cleaner' configuration of the engine cover works in partnership with the heavily-revised rear wing adopted at the last race. Since their introduction around two years ago, the horn winglets' prime function was never one of downforce, but rather as airflow conditioners, aiding the efficiency of the rear wing. It seems McLaren's latest rear wing doesn't need that help, and removing the horns also gets rid of the small additional drag they generated.
