The E-75 Standardpanzer was intended to be the standard heavy tank to be used as a replacement of the Tiger II and Jagdtiger
About this creation
The Entwicklung series, more commonly known as the "E-series", was a late-World War II attempt by Germany to produce a standardised series of tank designs. There were to be standard designs in six different weight classes, from which several specialised variants were to be developed. This was necessitated by the extremely complex tank designs that had resulted in poor production rates and mechanical unreliability.
The E-75 would have been built on the same production lines as the lighter E-50 for ease of manufacture, and the two vehicles were to share many components, including the same Maybach engine. The E-75 would have had much thicker armour however, and in fact compared to the Tiger II the E-75 had improved hull armour all round. As its name indicates, the resulting vehicle would have weighed in at over 75 tonnes, reducing its speed to around 40 km/h. To offset the increased weight, the bogies were spaced differently than on the E-50, with an extra pair added on each side, giving the E-75 a slightly improved track to ground contact length.
According to some sources, the similarities between the E-50 and the E-75 went further; they were to be equipped with the same turret and 88mm L/71 or L/100 gun, along with an optical rangefinder for increased long range accuracy (German scientists and engineers had successfully designed a 'schmal' or narrow turret and infra-red lighting and sights for use on the prototype Panther F as the war drew to a close). Other sources however, indicate that the E-75 was to be fitted with the much larger Tiger II turret, which could be adapted to accommodate an even more powerful high velocity 10.5 cm gun.
Many sources indicate that the E-75 was to have 185mm – 80mm of armor. The original complex suspension by torsion bars was simplified with bogies. The standard turret was to be equipped with 12.8cm KwK 44 L55 gun. The engine was an improved Maybach HL234 which had 900 hp to 1200 hp with supercharging. Maximum speed was supposed to be 40 km/h. Taking into consideration these facts, no Allied tank or anti tank gun could defeat the E-75's armor unless if it was shot several times in the area of 80mm armor.
On May 8th, 1944 the general staff ordered the development of a 5.5cm Flakpanzer with a Zwillingsflak (twingun). The twin-guns should be integrated in a turret. Krupp and Rheinmetall got the order for the development of the turret. The turret was designed for the E-50/E75 tank and the ability to store 104 rounds ammunition. Only a wooden prototype of the turret had been constructed by January 1945.

now these are interesting WWII German AFV that never made it to the production line but you have made it possible (in lego! haha!).
I am particularly interested in WWII German AFVs, seeing your creation has meant a lot to me. (: and it's great that there's instructions!
