Williams FW 28 - turning vanes 09 June 2006

The area immediately in front of the sidepods is a crucial one in terms of a car's overall efficiency. At Silverstone Williams have reintroduced a solution seen on last year's car - a narrower and more pointed turning vane, profiled like a wing, replacing the squared flat one used more recently. In addition, the small barge board in front of the main one has been removed to reduce turbulence. These changes improve the aerodynamic balance of the car at high speed, the compromise being a slight loss of stability in slower corners.
