Red Bull RB11 - Austin front wing

In the United States, Red Bull and McLaren were the latest teams to take on board key aspects of Mercedes' front wing design.

As can be seen in this drawing of Red Bull’s interpretation, the outer section of the wing has a small step (underlined in red) next to the endplate. This entire area consists of various channels which better direct airflow towards the outside of the front tyres, thus boosting downforce. Both Red Bull and McLaren raced their solutions at the Circuit of The Americas.
