Two weeks after making the first variant of the VK100.01(P), Professor Ferdinand Porsche prepared a buffed version, designated Typ 205. This comes from a drawing no.K3382, dated 17.6.1942
Since the Führer already requested the tank to be slow, the engineers really unleashed it this time. The armor was increased overall. Combat weight increased from 120 tons to 140 tons, but the engine (a V16, most likely Porsche Typ 191) remained the same. However, it didn't end with the armor increase. The Führer decided that in order to fight the Soviet infantry, a short-barreled gun is needed. The designers fulfilled the will of Hitler with the directness of German Ordnung. Instead of installing a commander's copula, they did put one more small turret on top and fitted it with the 75mm KwK L/24. The idea, that was already in the head of Soviet engineers designing the KV-4 proved to be infectious.
However, in July 1942 it was decided to start from scratch. Since Krupp started to desire by that time to produce a turret of their own, even Porsche realized that it makes no sense to make this on the current chassis. And so they began to work on a radically re-designed project, which started to be called in July "Panzerkampfwagen Mäuschen".
