A recent windtunnel surprise, Volkhart V2 Sagitta

A German engineer K.C. Volkhart build, V2 Sagitta, was a rare aero-body built on top of the Volkswagen KdF-Wagen Type 60, Beetle. Two were eventually built, based on the work by famous German aerodynamicist Reinhard von Koenig-Fachsenfeld. It was initially designed to be a reliable & fast postal delivery/courier car for the Luftwaffe in WW2 but was only realized post-war with the funding from industrialist Sagitta. The clean body design (very similar to the dreams; Porsche 114 and Porsche 64) allowed a 1.1 liter 24.5 hp boxer engine to top speeds over 140 km/h or 87 mph! The recently measured body had a low drag coefficient 0.21 and a respectable 2.1 frontal area. Two times more aerodynamic than its base car and very close to it's contemporary family stablemate, the soon-to-be-available VW XL 1!!! 1947 VW Beetle-Based V2 Sagitta is More Aerodynamic than New Golf, Mercedes CLA! - Carscoops

Porsche's similar aero studies and shapes - precursors to the Porsche 356;

Type 114. Ferdinand did start with mid-engine layout! http://www.thebestporsche.com/news.php?extend.29

Type 64. Should have stayed with the engine midship. http://www.smcars.net/forums/attachm...yp-64-2700.jpg

1947 beats 1951, below comparing it to several Porsche 356 coupes.

Throw in a D15Z1!

Or better yet, the tried and true STi swap.

It's also reminiscent of the Porsche 60K10, a road rally car based on the KdFWagen (the early version of the Bug)









It was designed for a Berlin-Rome rally which was cancelled by the outbreak of the war.

1939, and even closer to the 1947 sample first posted.

Two of Dr. Ferdinand Porsche's goals were to build an economical car for the masses and to build a sports car. The Volkswagen Type 1 (a.k.a. Kdf-Wagen) fulfilled the first goal and provided the means to realize the second - the little-known Type 60K10, which would be the basis for the postwar 1948 Porsche 356/2 coupe and the start of the Porsche sports car line.

That car doesn't have engine cooling or cabin ventilation. Tyres are super skinny. Those modifications have big effect on aerodymic drag.

Please quote the source of your information.

From what I can see, all 3-4 cars mentioned are air-cooled and have inlets at the rear.

Porsche 356's have cabin ventilation, although as with the later 911 it's not very good.

Concorso D'Eleganza Villa D'Este 2012, Class C


The Volkhart V2 Sagitta (1947) has inlets at the front, could be for the cabin ventilation, front brake cooling, horn, or a front mounted oil cooler, I do not know for sure but if I were to guess it would be cabin ventilation (actually looks like a fan). Cracking a window open I suppose would be an option.
