The BMW X is a small five-cylinder radial engine for sport and training aircraft. Although this engine proved successful at several large-scale events in 1930, including that year's round-Europe flight, only a few were built.
The successor model to the BMW X five-cylinder radial engine, the BMW Xa, was introduced in 1931, with the swept volume increased from 2.2 L (130 cu in) to 2.9 L (180 cu in). Power output went up from 37 to 51 kW (50 to 68 hp). The Xa was also not built in any quantity and was mainly installed in training and sport aircraft.[1]
