Mercedes F1 W05 Hybrid - new turning vanes 06 July 2014
Mercedes' Silverstone set-up featured these new turning vanes below the front of the chassis. The front wing pillars pull the airflow inward to get more mass airflow between the front wheels, but as this airflow gets to the front wheels it needs to be turned outward across the leading edge of the underfloor. These new turning vanes are that little bit more aggressive and the horizontal lower endplate (red arrow) is more three dimensional. It is very difficult to change the direction of airflow, but if you understand what the airflow is doing then you can then help it to do it that little bit better. That's what Mercedes are trying here. If it can be achieved they will get a little bit more downforce and that little bit more consistency.
