In 1927 Opel presented two models as successors to the 14/48 hp model that had been built for many years, the 12/50 hp and the larger 15/60 hp .

The engine power was transmitted to the rear wheels via a multi-plate clutch, a manual three-speed gearbox, a cardan shaft and a differential . The cars reached a top speed of 90 km / h.
