In 1917, BMW's first aircraft engine went into production, the 6 cylinder Type IIIa. In 1919, using an aircraft powered by its successor, the Type IV, Franz Zeno Diemer set an altitude record of 9,760 metres (32,013 ft). After the Treaty of Versailles was signed in the same year, prohibiting BMW from building aircraft engines, production switched to air brakes for railway cars. When BMW started once again to build aircraft engines in 1922, no fewer than 29 world records in aviation were set with them. The current BMW logo, introduced in 1920, was based on the circular design of an aircraft propeller.
The legendary German marque that is so well known for its automobiles actually has its roots in motorcycles. The first BMW motorcycle, the R 32, went into production in 1923 at the newly constructed Eisenach factory next to the Munich airport of the day. The R 32 used a flat-twin engine transversely mounted in a double-tubular frame producing 8.5 horsepower at 3300 rpm. The 2-cylinder 494cc motorcycle could reach a top speed of 59 mph (95 km/h). BMW manufactured 3090 of them during its 3 year life span.
1932 was the year the BMW AM 4 (Ausfuhrung Munchen 4 Gange - Munich Version 4 Speeds) - a.k.a. BMW's first "real" car - went into production. The AM 4, also called the 3/20 PS, was the successor to the Dixi and the first production car to be built entirely in-house by BMW. The powerplant was a 782cc 4 cylinder unit which featured suspended valves and a double chain driving the camshafts, producing 20 horsepower at 3500 rpm and providing the saloon with a 50 mph top speed.
