Oh Yes! Inside the Panzer VII Maus – It Has a Massive 44 Litre Engine!

Panzerkampfwagen VIII Maus (“Mouse”) was a German World War II super-heavy tank completed in late 1944. It is the heaviest fully enclosed armored fighting vehicle ever built. Only two hulls and one turret were completed before the testing grounds were captured by the advancing Soviet forces.
These two prototypes – one with, one without turret – underwent trials in late 1944. The complete vehicle was 33 ft 6 inches long, 12 ft 2 inches wide, and 11.9 ft high. Weighing 188 metric tons, the Maus’s main armament was the Krupp-designed 128 mm gun. This 128 mm gun was powerful enough to destroy all Allied armored fighting vehicles then in service, some at ranges exceeding 3,800 yards.
