Odd in the marriage of wedge shape (lower body) and teardrop shape (greenhouse canopy), however it works in my opinion.

Bubble-top coupe (1964½ Mustang, M-B 300SL and etc.). To me is appears a rough draft — That wing over the top creates a diverging duct. What would that do to the pressure and velocity? Bertone did the BATs, it looks like they experienced the 1980s like everyone else.
That Sbarro is a hard 0.26.

Interesting phrase should one do a Google image search.
1960 Chevy Impala Bubble Top Sports Coupe

Custom Citroën DS Coupés and a Peugeot Food Truck
https://citroenvie.com/custom-citroe...ot-food-truck/
Top one has a trunk so long as to act like a Bonneville style rear spoiler?
Bottom one does not follow the aero-template ( I suspect) but like the EV1-Impact could prove to be slippery Cd wise.
EDIT:
This is just cool.
Again, I wonder if the long trunk approaches the template.

Quote:
Chapron switched his attention to the recently launched Citroën DS. Chapron’s first rebodied DS coupe was the 1958 Le Paris. [2] At first, Chapron purchased these vehicles and customised them as one-off creations. Many of these became unique convertible variants. His DS convertible caused a sensation at the 1958 Motor Show. Citroën managers came to see him in Levallois to offer him a production agreement. For 2 years, the Chapron and Citroën teams work hand in hand in order to strengthen the safety standards on the car and to minimize the cost of production. On the basis of a design by DS designer Flaminio Bertoni, Chapron developed a two-door convertible body that was sold through the Citroën dealer network. The Series convertible was presented at the 1960 Paris Motor Show.

Happy to help.
Except: Duckduckgo, Bing, Yahoo ....or, the most tantalising — GTP-3.
I used to have a 1/43rd scale model of the Chapron Citroen convertible. My favorite Chevy (and Olds) is the 1961. There was also, earlier in the 1940s and 50s, the business coupe.
https://s.aolcdn.com/os/ab/_cms/2019...9-hudson-1.jpg
I could have had one of these for my first car, but I passed on it for a bullet-nosed Studebaker (four-door, not the Starlight coupe ).
https://en.wikipedia.org/wiki/Studebaker_Starlight
(or the business coupe)

I collect pictures of business coupes because I think they look so much like cartoon cars.

I'm still curious about this. Compare with a coleopter or any ducted fan. I'd test an external duct lined with cold plasma actuators.
Example: a 50-50 morph of this and the Volkhart-Sagitta:
(Maybe an inverted periscope [Fresnel] back window)

I hear what you are saying, looks like a divergent duct.
model aircraft: THE RELATIONS BETWEEN PRESSURE, VOLUME AND TEMPERATURE
The Porsche 959 wing may be similar, notice the angle of the top plane and inner plane.
https://www.stuttcars.com/porsche-models/959/
I've always assumed that there was no attached flow on the back window, and that the wing actually served to fill out the aero-template similar to a Bonneville style spoiler.
This would explain the top side of the wing angle which if a normal wing the angle of attack is that of lift, not down force.
An oddity, when a wing isn't a wing but a plane for re-pressurization or semi-attachment at trailing edge.

I've described this style of roof as maybe related to the double bubble roofs that rise up over the front passenger plus driver, and theorized it may add entry and egress via raised upper portion.
However, this caption claims it's simply to keep the rain from washing on your head as you get in and out.

A roof of Toyota Prius. It is designed to prevent rain water from flowing towards the doors. The doors are higher than the roof, too, to stop rainwater from flowing over the doors.

An odd detail, beats old fashion rain gutters I guess.

IIRC Mercedes-Benz called their's a Pagoda roof.
The one thing that disappoints me about the XFi is there's no way to attach my roof racks, and I have to blow pine needles out of the upper door jamb every few days.
