Random Aerodynamic Oddity of the Day Thread

The Hybrid still has air curtain ducts, but a single vent on each side.

Audi is also using the double-vent setup on its forthcoming e-tron S and e-tron Sportback S:

The controlled airflow at the front wheels is fundamental to the aerodynamics concept. The side air inlets in the front – the air curtains – route the air over a channel in the wheel houses to optimize the airflow to the wheels and the vehicle flank. The airflow through the wheel arch trims serves the same purpose: Narrow horizontal bars in the recesses formed by the widened trims in the front channel the airstream to surround and encapsulate disruptive swirl in the wheel houses. The upshot is “cleaner” airflow along the vehicle flank with reduced flow losses. The design of the 20-inch wheels as well as the tread and the pattern on the sidewalls of the tires have also been optimized accordingly.

This is for those who disparage the 'Paris dressmaker' aspect of producing a marketable vehicle.

Styling And The Experimental Car (1960's)

TLDR; they throw things at the wall to see what sticks. Totally comprehendible at 1.75x and the music is may be less obnoxious at a higher pitch.

Here's a review from www.autoweek.com/car-life: Film Friday: 'Styling and the Experimental Car' takes us from Da Vinci to the Ford Mustang

This reel's objective, then, is to connect Ford's wildest flights of fancy to the very real car. It does so by walking us through a series of concepts. There's gorgeous little Allegro, the Cougar II, the Aurora (a concept wagon that boasted a primitive GPS system and cruise control).

My fav is the Aurora. Subby SVX-style A-pillars, L-shaped back seat w/ AV center, and that trick loading ramp/sliding 4-bar tailgate. The mockup of an autonomous driving setup is prescient.

The pony-car shaped Allegro has a cantilevered steering wheel. That could be adapted for autonomous vehicles and adapted to left or right-side driving jurisdictions.

In the video at the 7:30 mark, why hasn't any auto-maker done similar for Right & Left hand driver sides?

I can picture a center hub with an armature to the steering wheel that can be rotated R&L, so if in France it's one way, in England another way.

Pedals could slide on a rail and follow along.

Gear shift stays in the middle.

Vehicle would have to have headroom (windshield) clearance for arm to swing, or have a Jeep-like folding windshield, or be a convertible.

Yea, guess it's more complex once one thinks about.

Will be easier to do on drive by wire vehicles with automatics and or electric cars though.

Probably a null issue with autonomous vehicles anyway.

It's a hydrofoil, flipped up out of the water, on the side it is not needed:

I suspect the video is of the first Airbus sponsored/supported boat because the image I originally posted looks more aerodynamic, has a fine tail verses the blunted transom in the video.

I've been fascinated by these hi-end foil sailing boats for years, they seem to defy physics while actually embracing physics.

The Airbus sponsorship and sharing of technology is interesting, I had no idea. Thank you for posting the video.

One of the videos that came up after watching the video Freebeard posted is about air and vacuums. They start with thunder, lightning and natural weather.

It's all supposed to end up explaining a transmission.

AN EXPLANATION OF THE PRINCIPLE OF THE NEW VACUUM GEARSHIFT, AND HOW IT CONTRIBUTES TO COMFORT, EASE OF DRIVING, & SAFETY.

An even better video, at the 1:15 mark is a simple device used to examining eddies and vortexes - something smoke really doesn't do well in my opinion.

I like this view because it says MAGIC right on the sail.

I remember seeing someone comment somewhere about Cleetus McFarland adding panels to Leroy (the stripped corvette) for aerodynamics. Well apparently they brought it to a wind tunnel. Cd .74 was what the wind tunnel operator said.

I didn't watch the whole video.
