Red Bull RB22

[organic]

It's not dramatically different.

Not sure I agree with you there. There was zero undercut before and now it has quite a significant undercut, more than I expected it to have. It doesn't look as dramatic as some of the other undercuts, but that's mostly because of RB's narrower sidepods. This change will make a big difference to how the air travels towards the rear of the car.

I personally judge an undercut by the G-line or how much floor is visible. And based on that criteria it's not that different. For sure the flow architecture has changed...but I'm sure a real F1-engineer might judge it differently.

The floor edge curls upwards outboard, so the relative amount of floor upper surface planform exposed by a differing SP geometry is in my opinion, very difficult to judge from most angles

Seems like vortex generators to increase heat transfer.

Useful to control how the flow swirls between the cake tin and the wheel rim. Mclaren has demonstrated interest in this area:

Has anyone else noticed how the top of the monocoque sweeps down after the antenna's toward the cockpit? Looks way more extreme than other cars.

My theory is that they are trying to raise the monocoque up as high as possible in order to make more space behind the front wing and in front of the bib. It needs a minimum cross section in order to pass the crash test, so they can't just lift the bottom without raising the top.

Or just to have the entire top surface from cockpit rearwards downwashing
Good view of what's left of the SP/floor edge overhang too

What's the black element behind the FW in the first image? If red bull had a vertical fin under the main plane like alpine's scythe then I'd say that but they didn't yesterday

Back to old front wing on day 2.

Similar run program as Hadjar. Comparison of the two wings on low fuel.

Just set the cars fastest lap of the tests with the new front wing.

and tons of flow viz.

The overhang on the floor is actually quite small now, maybe they moved away from it a bit as it didn't gain them as much performance as they thought?

Do you think RBR has more development potential or lets say has more to play with in terms of bodywork?
Compared to Aston or McLaren that have already so little bodywork, RBR has way more e.g. sidepod volume, where shape and geometry can be adjusted.

the scope for bodywork changes is somewhat dictated by the layout of internals obviously.

The pyramid-shaped castellations on the inside of their rear wheel are rather striking to see. They're not connected to the hub--strictly free-standing knobs. Those can provide structure in the sense of an truss bridge versus an arch bridge, but you have to assume an aero funtion as well, although...

Are they on the "rim" though ? with clear definition of hub, spoke, rim carrying different function, is that problematic for the written FIA wording again ?

Obviously in close proximity to static component, could bring speculation of torque converter effect in fluid dynamic consideration.

Extra mass will always hold extra heat, whatever the rules though. Increase in centrifugal effect too, when both compared to no such material there.

Interesting certainly.
