Unfortunately for the design team, the Me 209's proposed DB 603A engine was in short supply and they were forced to use the Junkers Motorenwerke firm's Jumo 213A engine.
Por desgraza para o equipo de deseño, o motor proposto para o Me 209-II, o DB 603A, estaba dispoñible en pequenas cantidades, e vironse obrigados a utilizar o motor Jumo 213A da firma Junkers Motorenwerke.
