[2][3] The M 37 prototype flew first during 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.

Particular among these traits was its low fuel consumption rate, good handling, and superb takeoff and landing characteristics.

[4] Soon after the first production aircraft began to roll off the assembly line in Augsburg, several Bf 108s had set endurance records.

Furthermore, a Bf 108 served with the small long-range bombing group Sonderkommando Blaich based in Africa.
