Over the last week this crossed the forum. I can't locate it, so I'll treat it out in the open where it won't get lost.

* The Sagitta, Porsche Type-64 60K10 Berlin-Rome, and Porsche 911 are all considered derivatives of the 1938, 'Lange' car, developed under the direction of Dr. Ludwig Prandtl, at the A.V.A. Gottingen, in Germany.
* The 'Lange' car is a Jaray, 'combination form' design, with lower main body, and upper symmetrical wingtip greenhouse glommed on.
* The greenhouse is designed to create as much flow besides , as is flowing over, and is 100% boat-tailed.
* The greenhouse also requires a panoramic, full, wrap-around, semi-circular windscreen.
* The 'Lange' car is very narrow, L / W = 2.781.
* It's fineness ratio is L /H = 3.576.
* Verjung. = 1.934.
* 'Lange' measured a featureless, smooth, model of the car at the AVA and recorded Cd 0.14.
* Later, Hucho and his co-workers at Volkswagen recorded Cd 0.16, on a 1 / 5 -scale, featureless model of the car.
* In SAE Paper 860216, Aerodynamic Characteristics of Subaru XT, T. Tsukada et al., Subaru Engineering Division, Fuji Heavy Industries, Limited, reported that in their history of 1 / 5-scale model testing, that results were within 97% accuracy, compared to the associated actual production vehicles.
* It may be Hucho's measurement which has been attributed to the Sagitta.
* The Porsche 60K10 has been reproduced, and wind tunnel tested, however the owners have not yet published the Cd.
* Neither the 60K10 , Sagitta, nor 911 share the more liberal dimensional attributes of the actual 'Lange' car.
--------------------------------------------------------------------------------------
* The 2002 Volkswagen 1-Liter Car is a 'Lange' car derivative, with Cd 0.159, lacking front wheel skirts.
