Designed by Ferdinand Porsche, who later became famous as an automobile designer and manufacturer with his own company, Austria’s Austro-Daimler produced one of the world’s first successful aircraft engines at the beginning of World War I, a water-cooled, in-line six.
The Porsche Automobile Corporation of Stuttgart-Zuffenhausen designed the Type 678, a converted automotive engine intended to meet requirements for light general aviation aircraft in Europe in the late 1950s and early 1960s, and the first aircraft engine developed in Germany after World War II.
Type 678 engines powered the Putzer Elster general aviation aircraft, the RFB RW.3-A3 Multoplane aerobatic and sporting aircraft, and the RFB RW.3 –A2 Multoplane power-assisted sailplane.
