Both Red Bull and Ferrari raced at Paul Ricard with extensively modified floor inlet arrangements as their development race continues apace.The area of change in both instances is around the inlet fences to the underfloor tunnels. Teams are allowed three fences in addition to the outer ‘barge board’ which effectively forms a fourth fence. Generally their function is to accelerate the air into the venturi tunnels which create the underbody downforce of the car – and the faster that air can be induced to flow, the more downforce will be created. But there is downforce created by the suction effect of the tunnel (at its peak around the ‘choke point’ where the gap between the tunnel and the ground is at its smallest) and that created locally by the interaction of the air around the exposed upper and lower surfaces of the floor at the front. Aerodynamicists are trading off one against the other in order to vary the aero balance between the front and rear of the car.

RED BULL
Red Bull seem to use the arrangement of their fences at the front of the tunnels to vary the aero distribution from track to track as required. They have run many different arrangements already this year and it would appear that this is a key sophistication to the RB18.
FERRARI
The changes Ferrari made to their floor were less circuit-specific than Red Bull’s and part of their general development.
