Full-scale production of the Type 82 "Kübelwagen" started in February 1940, as soon as the VW factories had become operational. No major changes took place before production ended in 1945, only small modifications were implemented, mostly eliminating unnecessary parts and reinforcing some, which had proved unequal to the task. Prototype versions were assembled with four-wheel-drive (Type 86) and different engines, but none offered a significant increase in performance or capability over the existing Type 82 and the designs were never implemented. As of March 1943, the car received a revised dash and the bigger 1,131 cc engine, developed for the "Schwimmwagen", that produced more torque and power than the original 985 cc unit. When Volkswagen production ceased at the end of the war, 50,435 "Kübelwagen" vehicles had been produced, and the vehicle had proven itself to be surprisingly useful, reliable, and durable.
