This is a German design that reached only prototype status, but which is a fascinating subject nonetheless. The vehicle is the Ardelt-Rheinmetall 8.8cm PaK 43 Waffenträger.

The conceptual idea behind this weapon system was a self-propelled mount for the powerful but heavy 8.8cm antitank gun, as towed versions of this gun were too unwieldy for crews to move readily. Ardelt and Rheinmetall combined to build the first prototype and tests were conducted on this Ardelt I.

The vehicle’s engine was fitted at the front of the hull, which permitted the main armament – an 8.8cm L/71 cannon – to be fitted on the rear. It utilized a 38(t) chassis with four road wheels per side. An improved prototype (Ardelt II) was later produced by Ardelt and Krupp, but the end of the war intervened before production got off the ground.
