Random Aerodynamic Oddity of the Day Thread

[freebeard]

Let's put this one under Oddity although I like it a lot...

Panhard flat twin and VW Beetle headlights. As the narrator says "French function wrapped in German flair". I really like the rear fender opening, reminds me of an Indian motorcycle; and the wide five wheels (on tiny little drums).

1950 Dyna Veritas The 2 0L Dream That Killed a Legend

I think it compares with the the Dannenhauer & Stauss coachbuilt VW convertibles.

JACG: Briggs Cunningham, 1961 Le Mans mid-engine Maserati Tipo 63 Birdcage


Looks like a mid-engine D-Type Jaguar from this angle.

JACG: ever heard of a streamliner that was used as a roadside attraction? The Thunderbowl Comet was one, near Acton on the Sierra Highway, it was on a stretched L29 Cord chassis and eventually was bought and dismantled for its Cord parts.

The 1951 Le Mans 24 entry of #46 conspicuously marked Porsche’s entrance onto the world stage of motorsport. On their first outing at such a high level, the werks 1,100 cc 356 SL won its class and beat the rest of the 1,500 cc cars, too.

AI slop, view at 2x. There's a lot of repetition of the few available photos. It's basically over at twenty minutes.

Mid 30s coachbuilt laundry vans. Plus a lot of filler material to includ the Dymaxion, a Burney, the Studebaker factory, and etc.

The Bizarre Story of the Holland Coachcraft Vans – Art Deco Masterpieces Lost After the War

Apparently the biggest customer for Holland's vans was Collars Ltd. Best example with op-art paint job at 18:53

They were built in a tiny Scottish workshop, then moved to a government backed industrial park, then three years later WWII started and every existing example was cannibalized for the steel and aluminum.

The Ash frame construction is shown at 4:54. An interesting non-aero bread van with side-loading roller door at 15:17. Hero shot at 14:40.

Lots of non-Holland examples
•A conventional nosed van at at 4:22.
•The Arrowhead three wheelers at 6:01
•Airstream/Bolus type construction at 19:44,

In case you can't tell I like bubble-shaped vans. Probably my favorite is the one delivering eggs to Safeway at 17:40.

JACG: These are some new aero things I haven't seen before on this Civic


Whaddya think? Vortex generators?

TinEye didn't show anything (even though it is obviously hosted on that blog).
Google Images says "This silver car is a 10th Generation (2016-2022) Honda Civic Sedan featuring an aftermarket Type R style roof spoiler and trunk spoiler."
My default search is "google -ai," but once in a vast while, it provides something which appears to be of some use.
Searching for that term, I found many links to Walmart pages which no longer exist, but this one currently does:

2. Provide space for the airflow under the vehicle to decelerate and expand, thereby providing pressure recovery by providing a degree of "wake fill" or more accurately.
3. Does not cause excessive airflow separation and resistance and keep driving safety.
4. Made of quality ABS material, the item has high hardness and wear resistance.

I don't have any idea if it is actually supposed to do anything or if people are just trying to create another stupid trend.

I just wonder who started it.

1. and 2. sound like the difusser. It comes down to "excessive airflow separation" so likely they serve as fences to separate the airflow over the top and sides of the cabin. Maybe generate downwash onto the rear window?
