Williams FW27 - new turning vanes 05 March 2005

Gone are the horizontal fins attached to the central part of the car's stepped bottom. Instead they have morphed into pointed extensions to the sidepods, almost resembling a knife blade. These vanes split the airflow in two, with the lower part directed to the bottom of the car, and the upper part diverted over the stepped bottom and around the lower section of the sidepod, adding a good amount of downforce.
