Yes, the Ferdinand did not perform well in the battle for the reasons mentioned above. Out of the 90 built only about 48 survived the conflict. Almost half of them were lost. It was because of theirinability to protect themselves from close range infantry attacksthat a hull machine gun waslateradded to the surviving Ferdinands. Armor thickness was also increased. The "modded" tanks, I believe, were the ones officially designated as "Elefants". Allof them, during the Kursk battle, werereferred to as"Ferdinands"(named after Dr. Porsche). These Elephants performed better in defensive roles, as opposed to the offensive role they were used in during Kursk.

I've not seen any images of the Hooben tank, but I assume that since it is being called an Elefant, it will represent the post-Kursk version of the tank, having the hull machine gun andcupola, etc.
