The F2005 has undergone considerable development recently, and in France the car sports a large number of changes. Mainly they are aerodynamic, focussed on delivering a better balance to the car. These additional inclined fins on the side of the nose cone are at the level of the upper suspension wishbone. They work together with the wishbone's wing-shaped profile to effectively increase its surface. The fins therefore produce an increase in downforce on the front axle and also manage airflow to the better of the car more efficiently.
