BMW Sauber F1.07 - engine cover 08 July 2007
At Magny-Cours we mentioned how this new engine cover works in conjunction with the rear wing. At Silverstone, we look more deeply at the cover, which sports a dramatically elongated shark-fin profile on its top edge (red arrow). This helps to clean up the airflow directed towards the rear wing, though it is not this element alone that works to achieve this - so do the sculpted winglets placed behind the venting chimneys. These help specifically in optimising airflow over the lower profile of the wing, aided by the extremely low section of the rear of the sidepods immediately in front of the rear axle.
