Starting with the Mk IV (1945-1949), which continued a pre-war design with traditional, flowing lines, Jaguar advanced to the Mk V (1948-1951) with modernized suspension and brakes.

The Mk VII (1951-1956) introduced Jaguar to the high-end market with its powerful 3.4-liter engine, followed by the subtly improved Mk VIII (1956-1958) and the mechanically advanced Mk IX (1958-1961) with power steering and disc brakes. The compact Mk I (1955-1959) and the highly successful Mk II (1959-1967) set new standards in performance and handling for sports saloons.

The Mk X (1961-1970) capped off this era as a flagship model, featuring a wide, low body and luxurious interior. These models are renowned for their classic British design, advanced engineering, and significant impact on Jaguar’s legacy.
