 Nissan by now had had developed a habit of occasionally skipping the next obvious designation in their model code system, and the Patrol series was no different when they went striaght from the 4W61 to the new 4W65 in October 1958.
 The new 4W65 Patrol was another evolution of the original 1951 4W60 Patrol, but this one had some significant changes. In an attempt to make the vehicle look more contempory, and less agricultural, several changes were made to the styling at the front. The most noticable of these was to the front guards, which are now much more rounded, rather than the flat planks on the previous models. The front featured the obligatory new grille design, which was similar to the 4W61 grille, but now all the horizontal bars are chrome plated, on the 4W61 only two bars were plated. The 4W65 has a new bonnet design, which is flat at the front, but has a bulge that starts a couple of inches from the front of the bonnet and extends backwards. The bonnet also has a painted strip that runs down the centre. The badge on the front says Nissan, and on the sides to the bonnet there is now a Patrol badge. Also introduced at this time was the WG4W65, which was a long wheelbase 8 seater hardtop wagon version.
 The 4W65 used the same engine as the previous 4W61 Patrol, which was the Nissan NC engine, which was a 3960cc 6 cylinder side valve engine that produced 105hp.
 In December 1959 the very short lived 4W66 model was introduced. This new model was externally identical to the 4W65, but very different mechanically. This model featured the new P series engine that would soon go into the all new 60 series Nissan Patrol. The P engine was an overhead valve 3956cc 6 cylinder engine that produced 125hp. The 4W66 had one of the shortest production runs of any Nissan ever, when it's run finished six months later in June 1960.
