A lot of details very different from SF23 evo sidepods, no SIS bulge, no inwash geometry, comletely new inlets, seems like a waterslide is there also?

Isn't that that the SIS bulge?

Yes the SIS tube is essentially exposed in the undercut . Very visible from this shot

That is hideous...

They were able to keep the airscope and the higher part of the car tight, despite having waterslide sidepods and therefore much less space.

Well, I would call that a bubble, like launch SF-23 had. Sf-23 evo has a big bulge which is there on purpose and has an aerodynamic role, this bubble on Haas is there because it has to be. This is what I'm referring to.

Outwash generation has evolved to allow for decent full-length undercuts as demonstrated by both cars, by using big bump geometry on the sidepods. This creates a narrow channel for the rear part of the undercut with converging undercut under the intake - where the pressurisation takes place. So instead of a blunt, draggy design of F1-75 and early AMR23 with a "simple" outwash intake undercut, this solution allows for less frontal area for a decent outwash effect.

That's quite a big cannon outlet that won't to a lot of good for top speed figures, most likely a very cautious and conservative cooling approach.

Well, imagining the car with the old sidepods, the cannon exit almost disappears, IMO:

Big fan of how their new sidepods look with the skinny roll hoop.

I disagree with that. The proof will be its absence next season.

When did we become such literal thinkers on this forum?

I wasn't talking about the presence of the bulge, but rather it's purpose which is the same as the outboard outwash bulge on the RB. RB bulge is further back and far more subtle, Ferrari had to make due with SIS tube and did the best they could. New Haas design does not pronounce it, I guess because the bubble which is there makes it impossible to achieve the optimal pressure and flow field.



The yellow circle on top is where the sidepods are widest on both cars. It is just above the undercut, making sure the benefit of both features is optimal.

The yellow curve on bottom is where this point is on RB19, circled in green. Purple circle is where Haas and Ferrari are widest. This shape suggest slightly bigger pressurisation in this area than RB, however this does not meant the outwash is stronger or better, but it almost certainly means the drag generated is ever so slightly higher.

haas still using the squarely stepped leading edge of the floor that debuted on Ferrari @ France '22 and has since been abandoned by them. Pic 4/5 show this

The cannon/engine cover is huge/unwieldy compared to other teams' attempts at this design. To me it feels like many compromises have had to be made to ditch the inwashing/tub pods and adopt waterslides.
