BMW Sauber F1.07 - double tail winglet 05 August 2007
Overall downforce loads are even greater at the Hungaroring than in Monaco. Every possible piece of bodywork is finalised with this in mind and every year teams try to reduce the additional drag the changes create. On the F1.07 the usual single tail winglet on the rear crushable structure has been doubled up, with two curved and steeply angled profiles (red arrow). These help to keep the rear of the car stable on a twisty circuit by opening up the airflow and aiding air extraction via the central section of the rear diffuser.
