The Jaguar Mk V  1948-1951

Years 1948-51
Notes New post second war model to replace the prewar SS Jaguar models which had been produced from 1937-1939 and manufactured again from 1945 as Jaguars (after the name change of the company from SS cars to Jaguar Cars.
After the war, every manufacturer, including Jaguar, was keen to produce exciting new models, and the Jaguar management had in mind a new flagship saloon. This however took longer to design and produce than they would have liked, and did not finally appear until 1950 (see the MK VII section).  This new model was to feature an all new engine, chassis and updated bodywork. An interim model was needed to sustain buyer interest, so Jaguar took the new chassis they had designed, and clothed it with mildly updated bodywork. The new engine still needed further development work at that time, so they retained the pre-war Standard Motor company based engines in 2 1/2 and 3 1/2 litre capacity.  The new chassis featured an independent front suspension and softer rear springs than the previous design. Overall stiffness was increased markedly. This chassis went on to become the basis for all the separate chassis Jaguars, lasting until 1961. The same chassis in shortened form was also used for the new XK120 which also made its first appearance in 1948. The XK120 also became the test bed for the new XK engine. (the reason the XK120 could feature the XK engine, whereas the MK V could not, was that the MK V was a production model, whereas the XK120 was initially conceived as a low production hand built model)

Despite being very close in appearance to the pre-war SS Jaguars, in fact the body was entirely new, and the interior was also completely updated, and very luxurious featuring standard leather seating, and a sunroof.  

Both models also featured a relatively low production 2 door drophead coupe model, as had been the case with the prewar models.
