Comparing: Object 140 vs. E 50 Ausf. M

An experimental medium tank. Developed between 1953 and 1958 in Nizhny Tagil to replace the T-54. Two prototypes were built, but in 1958 the project was terminated in favor of the Object 430.

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.
