Williams FW27 - barge board development 07 May 2005

In Barcelona Williams adopted a revised version of their big shields, providing them with a different knife-edged profile at the bottom. They now sport a sharper 'tooth' shape, instead of the continuous profile seen previously. This change is not dissimilar to designs used by Ferrari and Renault, splitting airflow in this area to reduce vortices and at the same time improve efficiency around the bottom of the car.
