I don't think the final car will be like that. If I were a betting man, and I ain't, I'd push the mirrors as far back as possible, because those horizontal strakes will help clean up the rear tire wake.

I had to double check but I think the Haas mirrors are pretty close to that. There's a question of if far back or as far from the centreline is more beneficial - if I had to chose I think wider it better because it's a longer mount to turn the air down.

Interesting discussion on the new cars from Driver61 and Scarbs.

Who was it asking about this sort of 'moustache' front wing? This is as high as you can get the nose tip and wing within their respective volumes.

That was me (and k.ko100v). This is what I sketched out (very rough, sorry) using your regulation boxes (thanks, by the way). By making the nose as short as possible, it looks like nose tip can sit quite high in its regulation box. Unless I'm missing something?

Like so. I'm not sure it'll be the dominant concept. The Haas seems to be somewhere in-between max and min height.

One benefit is that it forces more twist to the wing, span wise. Birdies twist their wings and it adds more directional stability, especially under yaw. Like the mighty albatross.

Imagine our buddy there flying backwards, pretty good wing if you cut out all the animal bits and only focus on the aero.

I'm wondering about the rear wing, it seems like it's a diverging duct. Since the airflow seen by the rear wing is subsonic at the leading edge, a diverging duct would only serve to slow down the airflow under the wing, making it more prone to detach. Where the endplate and rear wing meet, it is a diverging duct, thus the wing is diffusing subsonic air and slowing it down, encouraging it to detach. It has to reach a critical velocity before the flow can attach itself. Not only does this make the wing behave like an on/off switch, it also lowers its efficiency at lower speeds.

A converging duct would accelerate air under the rear wing, up to a point, I wouldn't be surprised if we see teams making the endplates cross sections of trumpets. Converging at the leading 10mm edge then flaring out in the final 3mm the regulations allow. Bonus points if the rear wing ends up making a badly played flute sound. :mrgreen:

Don't forget that birds use this as the anhedral --> dihedral packages nicely and the yaw stability is becuase the side force centre of pressure is rearwards of the COG. In these new cars any forwards vertical surfacing would decrease stability.

Steven knows - it's being worked on.

Cheers, I appreciate the thought. 👍

EDIT: apparently it's been fixed.

So he thinks Haas are trying to use the front of the sidepod to control tyre wake to some degree - as discussed in the Haas thread. Also getting downwash in to the floor too.

Some interesting points raised in that video.

Indeed so. Somewhere in-between that and lower i'd say but yeah!
