Williams FW30 - long shark-fin engine cover 25 May 2008
At Monaco high downforce is key and to improve the FW30 in this respect, Williams have followed the trend set by Red Bull and followed by Renault and Toro Rosso by introducing a shark-fin engine cover. The fin is very long and extends towards the rear wing, eventually tapering down to draw level with the main wing profile (yellow arrow). It increases the efficiency of the rear wing and provides a huge amount of downforce. Attached to the rearmost tip of the fin is a small winglet (red arrow) which is designed not to add downforce but to keep the cover stable and prevent the fin from bending.
