Interesting Aerodynamic Cars (Mike Vetter's ETV, also Avion)

What year was that done? There's more than a hint of Luigi Colani.

I started sketching it in the mid-1980's, didn't build the model until about 2000 or slightly later if I recall correctly.

Yes, back of my mind Luigi Colani must have influenced it, and as mentioned before in this forum there was a TV show in the mid 1980's (when I didn't own a TV) that had a helicopter incorporated into semi-truck cockpit. Don't know if I ever saw it, but may have heard about it.

In general, I grew up about 1/4 of a mile from the world's busiest truck intersection (1970 Guinness Book of World Records) and have always wanted to incorporate my interest in aircraft and sports cars into a big truck.

The original Lear Jet and the mid-1980's Ferrari Testarossa were of greater influence than anything else in my conscious mind. The clay model lacks the side intake fin/rakes of earlier designs.

In the back of my mind, always some Gerry Anderson's Thunderbirds and I guess some of the Tonka Toys and Hot Wheels that were around in the 1960's-1970's.

We are a product of our culture, and our thinking and preferences reflect that.

The cars : Ford Sierra development story
https://www.aronline.co.uk/cars/ford...pment-history/

The Sierra had been developed without prior knowledge of the C3-generation Audi 100’s highly aerodynamic shape, which made aerodynamics de-rigueur. Of then-current production models, the Sierra’s drag coefficient of 0.34 had only been beaten by the Porsche 924 and Citroen GS. And as for its middle market rivals, no-one had come close to that figure.

Referred to as an ‘aeroback’ design by its creators on account of its bustle at the rear, the Sierra sported a similar body shape to the recently launched Escort Mk3 (known internally as Erika). The later XR4i improved on the standard car’s Cd figure by incorporating sculptured side panels to control air resistance across the wheel faces, as well as its iconic bi-plane rear spoiler. The result was a very impressive Cd of 0.32.

................This revolution in mainstream car styling was impressive enough for the Sierra to be displayed in England’s Victoria and Albert museum during 1982.

I believe that it was 1987, when Colani showed up at Bonneville, with his semi-trailer, full of his creations.
His Utah- 7 was reported @ Cd 0.18.
The tractor-trailer had Cd 0.40 imprinted on the tractor.
Same year, Renault's V.I.R.A.G.E., tractor trailer indicated Cd 0.298 with 700mm of boat-tail.
NASA had published that, without some sort of streamlining structure behind the trailer van, it would be very problematic to see anything below Cd 0.25.
Walter Korff, of Lockheed Aircraft Co., indicated Cd 0.20 for his boat-tailed, 1963 semi-trailer wind tunnel model.

She lacks plan-taper in the aft-body, however, Dr. Morelli sets a pretty good example.

What is it? Where is it?

I saw something similar in the museum in Reno, NV. The picture is lost on some backup drive somewhere.

I believe that the car at Harrah's Museum is Morelli's PF-Y. This 1956 M1000 is new to me.

Here's a nice pic of the Cd 0.256 prancing horse

I don't recall seeing a Corvette with fender skirts before. I wonder if there are mag wheels under those front Moon disks.

Someone ascribed Cd 0.32 for the car. Damned good for a supercar.
A template comparison showed her on contour, going sub-contour, then rebounding back to the template before breakaway.
' hope McLAREN publishes numbers for their Speedtail one day. I thought of the Jaguar the instant I saw it.
If I ever make a fortune selling corrective headwear, I'd like one of each.
