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

[freebeard]

That is what I call a "smart looking" design, it just looks proper, just not fully aerodynamically proper.

Here's another view:



The stagnation point is a little high. In fact it's like an upside-down diverter. Would it not produce front-end lift.

It's a bubble-top coupe.

I'm interested in Aeroheads opinion of this, I like it myself.

Dual Direction Sports Car - It's a high-performance REAR-mid-engined sports car...
it's a high-performance FRONT-mid-engined sports car.
It's two, two, cars in one! Take one classic teardrop sports car of the 1930's and blend it with a dart-like mid-engined exotic of recent times, and you get a car that looks surprisingly like BOTH!
Step inside and be surprised by the dual-control positions, one facing in either direction!
(In Roman mythology Janus (JAY-nus) was the god with two faces, looking in opposite directions.)

So it's not real, it is interesting.

Flowing contours and perfect curves - a timeless automotive design. The 64 bears a strong resemblance to the Bug. In fact it was designed by the then head of Volkswagen - a certain Ferdinand Porsche. This car was a design precursor to the postwar production model that would make his name world-famous. The Porsche 64 was built in an extremely limited edition of three.

Janus GT — Mind sufficiently blown, but red's not my favorite color.

Porsche Type 64 — I was very surprised at the floorpan construction at 3:00. Triangulated I-beams, Okay. But what's with the two intermediate longitudinal members, and the two cutouts or brackets at each sill?

I guess they were experimenting.

This got me thinking, was Erwin Komenda involved with the Type-64?

I went ahead and Googled it, found the below.

KdF Berlin-Rome race car (Porsche type 64)
https://www.stuttcars.com/porsche-models/64/

For the 1939 race, in September 1938 a project was started to create KdF's Berlin-Rome competition car. It was a car using type 60 KdF-Wagen's mechanicals with design from Porsche 114 project. The KdF Berlin-Rome car was called as type 64. Its body design project number was 60 K10. K10 meant it was the 10th body (Karosserie 10) for the type 60 chassis. The type 64 cars were built using 1938 KdF VW38 chassis and the chassis numbers therefore begun with 38. The side view of the 'on paper only' type 114 and the type 64 was very similar. There were many body version of the 114 and the type 64 got its front look from the narrow cockpit 114. Having the powerless engine, the type 64 had to be as aerodynamic as possible. And the narrow cockpit made it look very cool. These aluminium-bodied cars were designed by Erwin Komenda.

Nice article the above is, and more of it below.

No. 1

The first KdF Berlin-Rome competition car, chassis number 38/41, was finished on August 19, 1939. Thanks to the streamlined body, the small 4-cylinder aircooled 1100 cc flat engine was capable of achieving more than 80 mph/130 km/h average speed on drives between Stuttgart and Berlin. The top speed was 95 mph/153 km/h.

The Berlin-Rome road rally had been postponed from 1938 to 1939, then to 1940 and 1941, but never happened. In 1940 Japan had joined the military alliance of Germany and Italy, and a Berlin-Rome-Tokyo road rally was thought of, but didn't happen.

The wider front fenders and the windscreen angle are the giveaways of the replica

[freebeard]

I may go back and turn on Javascript*, but the captions sound like there isn't a picture of when #2 was rat-rodded in 1949. I'd love to see that.

While it's described as 'curvaceous'; it's really bell-shaped; with the low overall height, super-wide sills and flat (on the original) four-wheel skirts. It's really an oddly shaped car. The replica seems to have compound curve skirts.

The Mathé open-wheel racer carries the Volkhart-Sagitta V2's low hood to the extreme. I'd want a 3D model that would morph smoothly between the three, were such a thing to exist. Parametrically driven, so it would accommodate one-four passengers and open/closed wheels in a single envelope.

*Phooey. "Subscribe to see the pics." As if.

Sportscar Legacies: Then and Now - 2012 Renault Alpine A110-50 Is A Blend of 1964 M64 and A110 Berlinette

I consider this a ten-year update to the Volkhart-Sagitta V2 as a set-back two-seater. It's got the same fender line falling away at the A-pillar, just extended further back with the bubble top set-back, and the Mako Shark nose and Corvette wheelwells bring it into the 60s.

Plus which, the Volkhart-Sagitta needs a Batmobile fin.

So it's not real, it is interesting.

It's visually quite interesting.
Traveling left-to-right:
*the nose is a fail (channeling air under the car)
*the sides below the greenhouse are a fail due to suction peaks/pressure spikes playing havoc with the boundary layer.
*Lack of significant actual plan taper kills meaningful pressure recovery,leading to lower base pressure.
*Backlight looks too aggressive.
*Rear slope looks too aggressive.
*Consumers would probably love it!
Traveling the opposite direction wouldn't necessarily correct any of its problems.

The Volkhart Saggita might have similar flow
