video: new Audi E-Tron in wind tunnel
A search for:' New Audi e-tron GT tested in the wind tunnel-has crazy aerodynamics' will bring up a video.
The smoke streamers are very 'nervous'.
The streamline closest to the rear upper body indicates cyclically attached, then separated flow, as if at sub-critical Reynolds number.
Nasty!
It's probably a very good thing that it has the rear wing.
When COVID's over, I'll find a 4-year-old to instruct me on links. Sorry!
--------------------------------------------------------------------------
There's also a video following, which shows a brief glance of a the Genesis G-70 in the wind tunnel.Flow over the boot doesn't look so good either.

This is why Apple resisted the two-button mouse for all those years. O'course on Mac OS, it's Cmd-C and Cmd-V.

I have no idea what's causing all that buffeting, it's such a clean looking design.

New Audi e-tron GT tested in the wind tunnel - has CRAZY Aerodynamics!
Maybe they are using some sort of special lighting to be more revealing?
I know that's I've complained about the smoke dissipating and disappearing by the time it gets to the rear of the car, have they solved this issue?
Perhaps with a UV Strobe-Light?
Is the apparent buffeting at the upper stream just a strobe lighting or digital recording artifact?

Thank you kach22i for your useful post.
They missed smoking the wake, the front air curtains and those wheels.

Maybe this picture will make JulianEdgar understand that we don't need a wing profile for Air Curtains.

At the very end of the above video I see some fill-in plates that are blacked out to make the wheels look more open. It would be great to see a photo of them with better lighting.
