The Minx sold between 1945 and 1947 had the same 1185 cc side-valve engine, the same wheelbase and virtually the same shape as the prewar Minx. This postwar Minx became known as the Minx Mark I (or Minx Phase I). Between 1947 and 1948 a modified version, known as the Minx Mark II was offered.

A much more modern looking Minx, badged as the Mark III, was sold from 1948. This was the first Minx with a protruding boot / trunk which effectively respected the Ponton, three-box design by then replacing the 'flat back' look, inherited from models that had made their debut in the 1930s. Three different body styles were offered initially, these being saloon, estate car and drophead coupé (convertible). Beneath the metal, however, and apart from updated front suspension, little had changed: the Mark III retained the 1185 cc side-valve engine of its predecessor. Claimed power output, at 35 bhp (26.1 kW), was also unchanged. However, in 1949 the old engine was bored out and compression ratio increased, for the Mark IV Minx, to 1265 cc, and power output increased by 7% to 37.5 bhp (28.0 kW). A Mark IV saloon tested by The Motor magazine in 1949 had a top speed of 67 mph (108 km/h) and could accelerate from 0–60 mph (97 km/h) in 39.7 seconds. A fuel consumption of 32.1 miles per imperial gallon (8.80 L/100 km; 26.7 mpg-US) was recorded. The test car cost £505 including taxes, the price including radio (£36), over-riders (£5) and heater (£18).
Further minor facelifts followed. In 1953, with the Minx Mark VI, a fourth body variation was added, being the so-called Hillman Minx Californian, a two-door hard-top coupé with, slightly unusually, a b-pillar that wound down out of sight along with the rear side window to give an unbroken window line when all windows were fully opened: the rear window assembly was of a three-piece wrap-around form. The wheelbase and overall length of the car remained the same as those of the four-door saloon and convertible permutations. For the Mark VIII, in 1954, a new ohv 1390 cc engine was installed. This was the engine which, two years later, would be carried over into the first of the new "Audax series" Minxes.
For a short time in the early 1950s Hillman Minxes were sold in the USA to Americans seeking better gas mileage. The reviews of the vehicle in the US were lukewarm. Between 1953 and 1956 the Mark VI to Mark VIII Isuzu Hillman Minx was produced in Japan by Isuzu Motors, prior to their 1961 introduction of the Bellel.
