Red Bull RB4 - 'shark-fin' engine cover 14 March 2008

During testing in Barcelona, Red Bull introduced a striking 'shark fin' extension to the RB4's engine cover (red arrow). The modification dramatically increased the surface area of this section and was introduced to provide better airflow to the rear wing and maximize the car's stability under braking. The new cover interacts in a very complex way with the rear-end aerodynamics of the car and its full potential has not yet been completely exploited. Such radical solutions are often hard to tune, though hopefully not so hard as to outweigh the benefits.
