The Nissan Patrol 4W60 begin production in September 1951. The look was a little different in their prototype. In fact, it looked more like a Jeep than the prototype. However, it was larger in height, width and length. It also came with a 75 hp side valve 3760cc 6 cylinder engine, compared to the 60hp four cylinder found in the Willys. The 4W60 Nissan Patrol was in production until August 1955, when it was replaced by the 4W61 Nissan Patrol.
