These vents/slots are interesting given that they are at different heights and are shaped like airfoils. What are the regulations like in this area? How many elements are you allowed, how far above the floor can they be?
Either way, the fact that they aren't slots, but actual elements is interesting. To the eye it looks like some of them will be spinning up some counter-clockwise vortices that will extract some air from under the floor. Are they sucking some air out from under the floor in an attempt to seal it better and increase ground effect, similar to the floor edge wings of the last regulation set?
Or are we looking at elements purely focused on spinning up vortices that try to control the tyre squirt by sending them along the inboard side of the tyre?
