The BMW 803 was a German aircraft engine, an attempt by BMW to build a high-output aircraft engine by coupling two BMW 801 engines back-to-back, driving contra-rotating propellers. The result was a 28-cylinder, four-row radial engine, each comprising a multiple-bank in-line engine with two cylinders in each bank, which, due to cooling concerns, were liquid cooled.
