BAR 007 - vertical rear fins 14 October 2005

Few changes on the cars for the final race, so let's take a closer look at existing features - for example, the vertical fins which act as pillars for the flip-ups in front of the rear wheels. These divert airflow inside the wheel (blue arrow), cutting turbulence and aiding air extraction from beneath the car, hence upping the efficiency of the rear diffuser's side sections. The fins feature a small outer winglet (red arrow) to help air also pass more cleanly outside the wheel, again reducing turbulence.
