Renault R25 - rear wing development 30 July 2005
A revised design for the tight, twisting Hungaroring, where downforce levels are higher than anywhere bar Monaco. A saw-tooth profile to the Gurney flap (red arrow) adds downforce, but also helps in detaching the airflow as it leaves the exit profile of the flap. This helps ease the inevitable disruption caused by vortices generated by the high wing angles at this track. The three horizontal slits on the endplates also reduce turbulence and cut drag.
