Comparing: 113 vs. E 100

Development on model 113 was started in 1963. The vehicle was conceived as an alternative to WZ-111 and used parts and components of medium tanks. However, the project was canceled due to the development of main battle tanks.

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.
