2020 Hyundai 'Prophecy' concept

[JulianEdgar]

Please note that Aerohead is here spreading his theory that rear spoilers are all about flow re-attachment. (Something that was last relevant to car shapes prior to about the mid 1980s, where early separation occurred, eg at the end of the roof.)

So that people don't get led astray, for a car of this shape, that idea is completely wrong.

Interesting. However that interior reminds me of some science-fiction inspirations from the '80s and '90s.

Yeah, good point both. I see that too. Angle is too fast, aerohead said. But the spoiler and the soap bar shape are cool looking, anyway.

Made me look.

I'm reminded of 1960s Porsche and Cal-Look VWs.

There must be a better term or description for this.

I have called "filling out the template profile" in the past.

I'd like to call it a "flicker" or "lick" because these rear Bonneville like trays flick up and lick the edge of the aero-template.

That was a good reference. Well, since it resembles a Porsche Panamera somehow, wouldn't be so surprising to also have other elements which may seem quite Porsche-ish

Proof? Are we in an anti-matter universe now?

This would be a pretty good word. This is what Kamm/ Fachsenfeld did at FKFS to create the 'Kamm-back.' Take the low-Verjungungsverhaltnisse Jaray body and loft its aft-body up to the 'template' contour. It gives you more useful internal volume, kills separation, kills lift,to make a 'neutral' lift body.
Drag coefficient is dependent upon the Vergungungsverhaltnisse (the ratio of the length of the aft-body,divided by the body height (not the overall height of the car), presented as a ratio. The lowest drag is achieved at V = 5:1.

I'm just glad the thread title gets the year [of the concept] right, now.
