Hugo Ruppe founded the Markranstädter car factory in 1909, producing cars that were sold under the brand name MAF. The first model was the Type D 4 from 1909 to 1913. Its air-cooled four-cylinder engine with 1192 cc provided 12 PS. The Type F 5 followed in 1913 with 1375 cc and 14 hp, and the G 6 with 1620 cc and 16 hp. Due to the outbreak of World War I in 1914 production was interrupted.
After the war MAF produced the pre-war type F 5, and the 6 / 18 hp which replaced the G 6. MAF also built the type 8 / 25 hp, and the large 14 / 35 hp with a six-cylinder engine. In 1921 the factory was taken over by the Apollo-Werke AG, and in 1923 the last models were produced by MAF.
