https://youtu.be/_laDsZl92W4 @12:30 they go into pretty good detail about the Aero of one of the vehicles at the show they go above and beyond what an ecomodder should do to get race quality/ quantity results but they explain a lot of the characteristics that we can apply to a less extreme extent for better economy.

Race quality, not show quality. As well they should.

Diffuser starts at the door handles, and you won't be rolling down the side windows.

I like how they plumbed the energized air from cooling system into the wake reducing the vacuum on the back side of the car creating a box cavity.
I could do similer with the dodge except draw the air from under the cab through the front bulkhead. Drop the tailgate lose the bumper add a diffuser from the differential to the end of the tailgate should work pretty sweet what do you think? Add a Bonneville spoiler :
2019 SCTA Rule book pg 60-61.
This would close off all but 3" of the sides , vertical , creating a nice box cavity. For street use add a pic of lexan formed to the bed side out to the end plate. (Inside sidewall width limmit)

The Porsche Taycan Turbo has a claimed Cd of 0.22:

With four-wheel skirts it might equal the 1947 Volkhart-Saggita. But I do like the 'white-wall' wheels.

VW ID.4 looks very interesting:

Compared to the open cockpit cars of the era, this was a vast improvement.
