Gary andersons take on it:

Anderson highlights a clever point that its like a wing flap that opens and closes. At high speed, the aero downforce will push the car down opening up gaps between the arms and the floor to reduce drag. At low speed the arms will be close to the floor to maximise the downforce benefits.

Does having those shutters really increase downforce? I mean after all this work that teams put in to slim down and undercut their sidepods to get as much flow over the diffuser as possible, it seems a bit counter intuitive. I'm not convinced with Anderson's analysis.

I don't buy "reduce drag" at all. I mean, compared to what? You would surely have least drag if you remove the contraption altogether.
Also, if blocking benefitted diffuser performance, why simply not have a big radiator outlet in that area?

[Mr.G]

Even if this is the way, won't be such device unstable? I mean you hit some bump and you lose downforce, etc...

Although I respect the innovation, I don't think that Macca would be able to convince Charlie W. that this arm must have this shape to function. On the other side, if the FIA wants to promote innovation, then they MUST accept this. My gut feeling is that it breaks the spirit of the rule both obviously and brutally, but what a great idea! Tough call either way.

Is the black vane on the sidepod a chimney?

Cooling Outlet!

Could, this suspension things are some kind of cover, that hide something that they don`t want to show us, from the first pre- test?

My theory on Mc rear "butterfly" suspension:

red: hot gasses from PU
green: "butterfly suspension"
yellow: very low pressure zone
under diffuser: almost high pressure

[dren]

That suspension set-up has to still be very draggy even when there are some gaps between the components. They will not open all that much as the car starts to squat.

Think this is the first time ever that I've been anywhere close to being right

Agree. While this is an interesting idea, it does not come at all cheap in terms of drag penalty. I also question them being allowed to run it as if it indeed moves then it is a movable aerodynamic device. Another DDD it is not.

[acosmichippo]

FIA can't say it's a moveable aerodynamic device if it conforms to their regulations regarding the shape of the suspension. If it does, it's just part of the suspension, and FIA must revise those regulations if they want to ban it.

I am quite sure you want high pressure over the diffuser and low pressure under it
