Comotor
Comotor SA was formed as a collaborative enterprise between NSU and Citroën in Luxembourg during April 1967, with the purpose of manufacturing Wankel engines.
Following the earlier 1964 partnership known as Comobil, which concentrated on engine research and development, Comotor provided power units for models such as the Citroën M35 and the GS Birotor. In 1969, Comotor secured an 850,000 m2 plot in Altforweiler, located in the German Saarland region, to establish a production plant.
Although Citroën initiated a two-year testing phase involving 267 M35 prototypes to evaluate the technology, persistent technical difficulties and suboptimal fuel consumption hindered widespread acceptance. The fuel crisis of 1973 further diminished interest in these engines. The heavy financial commitments made towards both Comobil and Comotor played a significant role in the economic decline and eventual insolvency of NSU and Citroën.
Between 1974 and 1978, Dutch businessman Henk van Veen developed the OCR 1000 motorcycle powered by the Comotor engine, manufacturing a total of 38 units.
