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 (1934).^[2][3] The M 37 prototype flew first in spring 1934, powered by a 250 PS (247 hp, 184 kW) Hirth HM 8U 8.0 litre displacement, air-cooled inverted-V8 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 low fuel consumption rate, good handling, and superb takeoff and landing characteristics.

The Bf 108A first flew in 1934, followed by the Bf 108B in 1935. The Bf 108B used the substantially larger, 12.67 litre displacement Argus As 10 air-cooled inverted V8 engine. The nickname Taifun (German for "typhoon") was given to her own aircraft by Elly Beinhorn, a well-known German pilot, and was generally adopted.^[4]
