The story
From 1911, Alfred Schwefringhaus took over the import of Foden Trucks from England to Germany.
The engineer Alfred Schwefringhaus from Düsseldorf-Oberkassel introduced a three-wheeled delivery van in 1913. The van, with two front wheels in a front-steering design and a single rear wheel, appeared under the brand name Asdomobil. The brand name Asdomobil is a combination of the initials AS from Alfred Schwefringhaus and the first letters of his place of residence in Düsseldorf-Oberkassel. A water-cooled four-stroke engine drove the rear wheel via a five-speed gearbox and a driveshaft. The open driver's compartment provided space for one person. Behind it was a box body for cargo. Next to the van, there was a nearly identical passenger car, also as a three-wheeler. Steam cars have also been produced in small numbers by Asdomobil. In 1914, a new logo for the company was designed. It consisted of the word 'Schwef', a ring, and a house, a play on the surname Schwefringhaus. The production of vehicles ended in the year 1914.
Alfred Schwefringhaus had published an article on the profitability of trucks.
