A new turret was designed intended to be simpler and lighter than the Maus turret. This design was very similar to the original 'Tiger-Maus' proposal, but had larger 900 mm (35 in) diameter road wheels and a new coil spring based suspension rather than the original torsion bars.

The design had removable side skirts and narrow transport tracks to make rail transport more viable. The second variant would have a new 1200 hp Maybach engine and a top speed estimated at 40 km/h (25 mph). The estimated top speed was 23 km/h (14 mph). Two types of engines were proposed: one was a 700 hp Maybach HL230, with a transmission and turning mechanism borrowed from the Tiger II. According to the blueprints, the tank would be armed with a both a 150 mm gun and a 75 mm gun. In March 1944, the Adler company in Frankfurt submitted blueprint 021A38300 for a super-heavy tank called E-100, after the tank was proposed in April 1943 along with the other Entwicklung series vehicles. It was the heaviest of the Entwicklung (E) series of vehicles, meant to standardize as many components as possible, in the 100 ton weight class other designs were the E-10, E-25, E-50, E-75.

The basic design was ordered by the Waffenamt as a parallel development to the Porsche Maus in June 1943. The largest of the Entwicklung series of tank designs intended to improve German armored vehicle production through standardization on cheaper, simpler to build vehicles.īy the end of the war, the chassis of the prototype E-100 had been partially completed it was shipped to the United Kingdom for trials, but was later scrapped. The Panzerkampfwagen E-100 (Gerät 383) (TG-01) was a German super-heavy tank design developed towards the end of World War II. 40 km/h (25 mph) (theoretically if terrain isn't taken into account)
