FERRARI TURNING VANE
Ferrari introduced a new front-wing endplate for the United States GP with a bigger gap between the trailing edge of the endplate and the trailing edge ‘Gurney flap’ on the rearmost flap.
On the rearmost flap, Ferrari has now fitted a small turning vane (blue arrows) in this area to help turn more airflow around the outside of the front tyre. It has also fitted a small vertical splitter (red arrow) in the outer endplate, which again will help reduce the amount of airflow the wing section will be pulling in under the endplate foot.
