They’ve got the old package on this morning. Likely be doing some back to back tests.

I think it's the Pirelli car with Norris. Notice the green rookie light

You are right. They have two different cars by the way

Any new parts yet?

Aero testing this morning.

Only 2 Vortice generators on top of Sidepod instead of the usual 3.

Looks like 3 to me.

Any thoughts?

Maybe flow-vis paint that's visable under ultraviolet light? Although I'm not sure why they're measuring it.

Apologies !! It's 3

Both wrong. Here's a clue, it's more than 3.

The underside of the nose is incredibly complex, with the nose nostrils feeding a slot (1,2) which in turn feeds the cape vane (3,5). The vertical slots (4) allow further airflow through. © Giorgio Piola

Underside of new Nose.

Best picture of how the nose ducts work. It's a reverse S duct. Instead of taking under nose flow over the nose. They use the fins on either side to perform the same conditioning as an S duct, meanwhile the cape gets blown by the nose slots speeding up the air underneath as it adds energy to the vortecies produced by the cape. At least that's what it looks to my brain, probably wrong.

Don't think the cape makes vortexes; it only channels the air.

Guaranteed it makes vortecies, guaranteed. It's simple, air underneath travels faster than air over = vortex at tips.

It could be either the angle at which the photo was taken or simply Piola is wrong. It's his interpretation of what the design may be.

There is a high chance he is wrong as in, it might work the way he is implying but that photo has a triagular opening vs a square opening in the diagram.
