I went looking for 'Epcot car' and found this from a DisneyWorld ride:

Cute little bug. The ride dates to 1999, i don't know about the car. But the back of the roof presages current practice by twenty years.

In the book's Chapter 2 on interesting aerodynamic cars from the past, I tried to feature mainly (1) production cars and (2) cars for which there was detailed technical aerodynamic development material available (eg an SAE paper).

I did add in a breakout interesting cars that often weren't production cars and/or for which there was less info available.

So I guess even with a Cd figure available for a PNGV car, I probably wouldn't have featured it. A full detailed tech paper? That would be a different story!

My attempt at an air curtain. I got this far, the system crashed and I never went back to it.



The outer face is flat but the air dam is compound curved to form a converging duct.

edit:
I just learned of the Bugatti Divo.

Bugatti's modeling skills are superior to mine. But the concept of the splitter upturned into a shark-fin shape open at the top is there.

Most cars of the same era are broadly the same shape, and most cars have huge expanses of 'fake grille'. It doesn't seem that difficult to pick up some ducting from a wrecked car, open up the grill and wheel arch liner, add some duct tape and done

OEM fog light holes can also serve as the inlet.

I ordered air curtain ducts from a Hyundai Ioniq to do just this to my car, probably get around to it this summer.
