The Messerschmitt Bf 108 Taifun was a German single-engine sport and touring aircraft developed by Bayerische Flugzeugwerke (Bavarian Aircraft Works) in the 1930s. Originally designated the M 37, the aircraft was designed as a four-seat sports/recreation aircraft for competition in the 4th Challenge International de Tourisme. The M 37 prototype flew first in spring 1934 powered by a 250 PS (247 hp, 184 kW) Hirth HM 8U inverted-V engine, which drove a three-blade propeller.
Although it was outperformed by several other aircraft in the competition, the M 37's overall performance marked it as a popular choice for record flights. Particular among these traits was its extremely low fuel consumption rate, good handling, and superb takeoff and landing characteristics.
