hello diffuser

This beam wing is like a secondary diffuser. It would be interesting if someone can run CFD simulation to see how it helps extract air from main diffuser

The undercut of the sidepods looks more extreme than it is because of the "scoop" structure and also because they've applied a reflective coating on the underside of the sidepods which is reflecting the track.

The "icecream sandwich" arrangement of the tunnel strakes is an interesting interpretation, you can kind of see how that could be generating a vortex that runs down the side of the car.

Hiding the car this long seems to have back fired, it's now the car every photographer is trying to get pictures of!

Is that sidepod scoop even legal? Does it fit inside the legality box?

We need an overhead shot to try and confirm, but it does appear to be in roughly the right place.

Can anyone enlighten me where in their packaging (and non existant bodywork) the seide Crash structure pylons sit?
Them must be very high up but their sidepod is also very narrow.

I'm a bit puzzled.

The undercut seems false economy to me when the midsection goes out so wide.
The sloping top section of the side pod is the focus, as the angle of the lower portion of the pod below the intake is angled much like a second barge board.

Severe undercuts in previous years was for getting a cleaner flow on the floor top section. This appears to be a secondary outwash manipulation flow from front of the floor.
The midsection is very bulky, as it goes wide at the hips. Which makes the "Side pod undercut" not the charged coke bottle flow that teams like Merc are attempting.

my guess

my guess

You can also see those sharp corners on the trailing edge of the floor strakes, clearly using those to generate vortices, and with the way the strakes are arranged they could be quite powerful vortices.

Looks awesome

They are using the undercut and wide sidepod to push air outwards and so push the front tyre wake outwards. They're attempting to undo what the new rules are in place to do.

has any other car done this? twin-layer not-a-bargeboard??
I noticed from some of the overhead angles, these bargeboards appear to be very big and long, in really close proximity to the Front Wheels.

Wonder how long before Mercedes protest the mirror stays!

Mercedes have the exact same philosophy and so they will be protesting themselves.

They have beam wing now, so maybe flow over floor and diffuser is not so important now.
better to manage flow slightly higher up in line with beam wing, gradual sloping sidepod used to manage flow better to beam wing?
maybe some CFD analysis van be done?

[Bernie's Mistress]

By arranging the undercut this way isn't RB attempting to move the centre of effort of the outwash from the sidepods rearward (ie where the tunnel venturi's are doing most of their work). The outwash from the side pod, lowers pressure and energises the floor in the same way the diffuser does as the rear (but to a lesser extent).

All the teams seem to be focusing on this to varying degrees.
