Between 1956 and 1958, Zündapp was also a car manufacturer. The Janus was an innovative small car with a mid-engine and passengers sitting back to back. Independent suspension all round and a self-supporting body were not standard even for expensive vehicles at the time. Because the Janus was too expensive and at the same time too underpowered, the hoped-for success did not materialize. After 6902 units, it was over. This report describes the history and the specifics of the Zündapp Janus, illustrated with many photos and archive images, supplemented by the original brochure and press dossier.
