BMW Sauber F1.08 - front barge board development 07 April 2008
As Sakhir is a medium-to-fast track, it is important to minimise the drag generated by the various aerodynamic surfaces impacting the airflow passing over the car. Even the smallest parts can produce drag that affects a car's straight-line performance, hence BMW Sauber's changes to the barge boards immediately behind the F1.08's front wheels. The vertical shields are now lower at the front (yellow dotted line indicates previous shape) and the small horizontal fin has been extended rearwards, so as to better direct and split in two the airflow exiting from beneath the front wing. This change may seem small, but it reduces turbulence noticeably at high speed.
