The Porsche Type 12 was a German project to develop an "Everyman's automobile" (Auto für Jedermann) for Zündapp.

Fritz Neumeyer, then owner of Zündapp, ordered Ferdinand Porsche to design and build the prototype in 1931.

Contemporaneous prototypes with a more extreme focus on aerodynamics were the 1933 Dymaxion car and Karl Schlör's Schlörwagen, developed from 1936 to 1939.

[1] The car's body (made by Reutter) has – for its time period – a reasonably aerodynamic shape with covered rear wheel arches.

[1] Unlike the VW Beetle, the Porsche Type 12 has a wet single disc clutch.
