2020 Hyundai 'Prophecy' concept
 
On page 29 of the July,2020, MOTOR TREND, are a couple of pics of their new concept.
She's a 'looker', and the author mentioned ' great lengths to minimize aero drag to maximize its range............. carefully swept-back tail to keep airflow attached as long as possible.'
There are pages of photos online.
With homage to the 911, Tesla,and M-B IAA, I'm uncertain what the drag could be. The existence of a rear spoiler suggests some aero compromise. No mirrors.
Windscreen looks like compound curvature. Small wheel arch gaps. Rear boat-tailing seems too aggressive.
She might make potential Porsche Taycan buyers take a look.
If they ever produced it, as a Hyundai partner, Canoo, BEV.

A great example of a car that without the rear spoiler, would have a lot of lift. Lots of attached flow over that camber!

Its interior may look quite dated, but the exterior doesn't look so bad at all for a 10-year old show-car.

It's a 2020 concept car.

I don't know if aerohead [as OP] can edit the thread title; it may take the mods. Worth fixing though.

The tight surface development over the rear wheel wells seems helpful for reducing the wake, compared with the 'shoulders' or 'haunches' on cars like 1967 Impala or 2010 Dodge Charger.

Looks like they forgot to close the trunk lid.

Wrong again! Keep looking.

The car is a Jaray, Combination-form hybrid. The lower body is pure Jaray, whereas the greenhouse lacks Jaray's plan-view boat-tailing solution.
The side elevation contour is too 'fast,' exceeding 23-degrees,producing separation,vorticity, and the famous fastback downwash; like the Porsche 911. And like the 911 Carrera, uses the spoiler as a palliative to address the flow separation.
Without a true-length overhead plan-view, it's hard to know if the boat-tailing of the rear fenders exceeds what the flow can survive.
The rear slanting truncation is a lineal descendant of Alfa Romeo Zagato TZ3/ Mercedes- Benz IAA.

Oh I see that.

Good point.

It does need that rear tray/whale tail.

I like it better than a wagon/shooting brake design, but it is not as aerodynamic because of air detachment.

For their 2019 Genesis G70 3.3T Dynamic Edition, a small reflex at the trailing edge was all that was deemed necessary for reattachment.
