Comparing: E 50 Ausf. M vs. E 100

The German Army demanded that the E-series tanks had transmissions positioned in the rear. However, the E 50 and E 75 tanks used the Tiger II engine-transmission compartment, which made rear placement of the transmission impossible. The E 50 Ausf. M tank was a redesign of the E 50 project with the transmission placed in the rear.

In June 1943, the Adlerwerke company received an order for development of the E 100. However, in 1944, heavy tank development was discontinued. By the end of the war, only the chassis was completed, which was later captured by the British Army.
