I have included some stat figures I got out of the Panzer Corps Forum in the downloading E series zip files for those who wish to utilize this series. This is all in the zip files if you download them. Unfortunately those stats do not cover ALL of the versions, but with reasonable comparisons relating to firepower, etc., one should be able to come up with equitable, fair and realistic stats to employ when using these units in the game. I also include a link I recently found on the web which may be of further benefit.

The E-50 Standardpanzer was intended as a standard heavy tank, replacing the Panther and Tiger II. The weight of these vehicles would fall between 50 and 75 tonnes. A conical spring system was proposed to replace the complex and costly dual torsion bar system. The Schmalturm would have been used, with a variant of the 88 mm L/71 gun. The Engine was an improved version of the Maybach HL230 developping 900 hp up to 1200 hp with supercharging. Maximum speed was to be of 60 km/h.
The E-50 although intended to replace the Panther medium tank into the German army was actually on part its measurements and weight a real heavy tank. Indeed this new project of the entwicklung series (E-series) was part of the class of 50-75 tons (E-50). More general design was that of the Tiger II. Like the Tiger II it was also armed with an 88 mm KwK L/71, but unlike the latter, the canon was installed here in a schmallturm (small turret) originally designed for the Panther. In the chassis the gearbox and transmission are installed as close as possible the engine at rear; a Maybach HL 230 to 900 HP. This provision would permit a better balance of the chassis and space won in the front allowed to embark more ammunition. Another important changes compared to the Tiger II, it is the running-gear which includes now only 6 steel road-wheels mounted on bogies, easier to maintain. The E-50 had to be equipped with higher-performance stabilization of the barrel and optical systems. The schmallturm were equipped with infrared sights for night combat. Also note that in a maintenance concerns the E-50 was assembled in a modular means, allowing for example to disassemble and replace the front part (made from a single block) in 25 minutes in theory. With its 88 mm KwK L/71, E-50 was capable to pierce 132 mm of armor at 2000 m (at 30 °). It is possible that a chassis was tested late 1944 but without known result.

In addition to standard battle tank (Standardpanzerwagen), the E-50 class based on the same chassis, included a range of specialized vehicle as the :
Jagdpanther E-50: a tank destroyer with back superstructure, armed with a 128 mm KwK gun
Flakpanzer E-50 Falke (Fantasy/Falke ?): an anti-aircraft tank equipped with a special turret armed with two 50 mm guns Flak.
Schützenpanzerwagen E-50 Buffel (Fantasy/Falke ?): a heavy armored personnel carrier equipped with a turret identical to that of the Puma armored car.
E75 Entwicklung Series data:
E-75 is in fact a heavy version of the E-50, intended to replace the Tiger II on the battlefield. If wholesale it conserves E-50 chassis, protection is improved, especially on the front. The additional weight was offset by a running-gear and suspension, although identical, were strengthened; now 8 road-wheels on each side and not 6 as on the E-50. In the interests of standardization, the E-50 and E-75 shared many mechanical elements. The engine was the same. The Maybach HL 234, with strengthened rods and a revised injection, coupled to an 8-speed box, could develop 900 HP. This should in principle ensure a maximum speed of 40 km/h on road. However delays in its development pushed back its delivery to the end of 1945 in theory! Note that expanded version of this engine with a supercharger, that can develop 1200 HP was envisaged for the future, as was an 8-cylinder Diesel Klöckner-Humboldt-Deutz AG of +1000 HP. As the E-50, E-75 was designed in a modular means. To accommodate the 88 mm KwK 43 L/71 or L/100 gun as it was initially envisaged, or definitively a 105 mm KwK L/52 45 or 46 L/68 (high velocity), one recovered the large turret of the Tiger II, with 180 mm front armor offered satisfactory protection against anti-tank weapons of Allies. The project to this tank exceeded never however the drawing board stage.

E90 Entwicklung Series Data:
The E-90 (sometimes named Tiger III) is a lighter version of the E-100 designed to replace the heavy Tiger I and Tiger II tanks. Less heavy (weight estimated to 92 t) should in principle be more manoeuvrable than the E-100. The hull that is identical to that of the E-100 (all less for its outward appearance) was surmounted by a redesigned turret of Tiger II armed with a 128 KwK L/55 gun. The proposed engine was a Daimler-Benz 517 of 1200 HP, which would have provided them with a velocity much greater than the E-100. In the worst case it would have welcomed a Maybach HL 230 of 700 HP or a HL 234 900 HP but with weight gain from 138 tonnes of the E-100, anyway, this would have represented a profit. The tank would have put thus reach a maximum speed of 38-40 km/h as the other German achievements. Note that although that lightened, the E-90 would have been equipped with significant shielding (maximum 200 mm) with few weak points to enemy guns. As you might expect, the E-90 and E-100 shared a maximum of equipment. About conversions, they appear to be also alternatives compared to the E-100; the E-90 Jagdpanzer designed by Bieber is virtually identical to the E-100 Krokodil.

E100 additional background material
E-100 was another competitor of Maus which falls under a series called " E-Serien " (Entwicklung Serien) gathering a whole series of new hardware whose majority did not overshoot the stage of the drawing boards. The development of E-100 began in June 1943 and continued until in at the end of 1944 when Hitler cancelled all the program of the super heavy tanks. However 3 employees of the Adler firm continued to assemble the prototype, work thus advanced very slowly. Nevertheless these 3 men finished more or less assembling of a complete prototype of E-100 in Henschel factory in Paderborn. However it was about a specimen without turret (the latter was a nearly identical version of that of Maus armed with 2 side MG34). The engine of the prototype was that of Tiger II, Maybach HL 230 P30 however insufficient for the 140 tons of the steel monster. The engine intended for the production was to be Maybach HL234 developing 800ch, which represents a weak improvement. A diesel engine Diamler-Benz of 1000ch was can be had a good idea. With the same turret that Maus or a specific turret (resembling more that of Tiger II), E-100 was to be armed with the 128 mm LwL 44 or the 150mm KwK44 L38 or with the 170mm KwK 44.
E-100 had a very traditional design with a frontal compartment for piloting, a central station of combat and a back compartment accomodating the engine and the fuel tanks. E-100 preserved many elements of Tiger II such as the front and rear decks, as well as the exhausts. The suspension with an aim of standardisation was so similar that of Tiger II with partially overlapping double road wheels. However E-100 was equipped with bogie trucks provided with two vertical springs in spiral. Each bogie truck supported a double-wheel . E-100 used tracks broad of 1000mm for the combat, it also had narrower tracks for transport. The shielding of the turret was of 240mm on the front, 200mm on the sides and the back whereas the roof was of 40mm. For the upper hull the shielding reached 200mm on the front, 180mm on the sides, 150mm on the back and 40mm on the roof of the hull. The lower hull had a shielding on front of 150mm, on the sides of 120 mm and 80mm for the belly. As Tiger II the top of the tracks was to be protected by anti-bazookas skirts. During the rail transport these skirts were taken off as well as the external road wheels, the pulleys of tension and the sprocket-wheels.
