from Herwig/Rhode "Geheimprojekte der Luftwaffe I" Early developements for a transatlantic airliner were started under the designator EF53 before WWII. In 1940 this project was continued for a postwar passenger service to the U.S. The designator was changed to EF100. While the EF53 was a four engine design, the EF100 already had six Jumo 223 engines. A total of 50 passengers should be carried in sleeper version with double bed cabins over a distance of 9000km maximum range. Up to 100 passenger seats were available in the non-sleeper version, which could reach distances of up to 4000km. A combined version with 75 passengers was designed for a 6000km range. The passenger cabin was fully pressurized. A windchannel model was built and a mock-up of the bar room was built for further discussions with Lufthansa. The development work was stopped after predesigns were finished. The EF100 passenger aircraft should went into further development as soon as the war was over. 
A parallel design of the EF100 as a widebody transporter aircraft was offered to RLM in 1940. But the RLM was more interested in large seaplane transporters as those aircraft could be used from any sea area instead of large airports. Also a bomber version with 5000kg bomb payload was under discussion But finally the EF100 development was stopped in 1941. In 1942 the RLM was thinking about a restart of the EF100 developement, as it was looking for a long range sea surveyer aircraft. Some prestudies were started at Junkers, but in late 1942 the complete EF100 developement was stopped. Technical Data:
