[1] In bodies such as automobiles and airships, drag decreases after the rear of a car's cross-sectional area is reduced to fifty percent of the car's maximum cross section; "the best position is nearer 45 percent of the length, and ... to have this maximum cross-section nearer the rear end than the front, and its drag has proved even less".
German Professor, Wunibald Kamm worked with aerodynamics engineer Baron Reinhard von Koenig-Fachsenfeld.
Thereafter, a prototype, namely the Kamm “SHW Wagen” incorporated principles that have become standard parts of the car engineering toolbox.
He did pioneering work in aerodynamics, driving dynamics, tire technology, minimalist construction techniques, engine combustion efficiency.
[4] He came to the U.S. as one of the first hundred German scientists stationed at the Dayton, Ohio Wright-Patterson Air Force Base and remained there as a consulting engineer until 1953.
[9] This automaker's naming of its coupé model appears to be the earliest use of "Kamm" to publicly describe an automobile body incorporating the Koenig-Fachsenfeld's design patent.
