Loosely based on the hull of the Sd.Kfz 231/6-Rad vehicle. The hull was modified to swap the main driver & reverse driver/radio operator positions in order to place the engine at the rear and the 3 axle truck chassis replaced with a pair of 2 axle 4 wheel trucks, for an eight-wheeled, all wheel drive, all wheel steering chassis to improve off road capabilities and maneuverability. The turret was also altered to a hexagonal shape for increased internal volume. Armament was unchanged.
