Old Minx Advert


Produced from 1932, the prewar Minxes all shared a common 1185cc side-valve four cylinder engine, but any advances they lacked under the bonnet were more than made up for in other areas with a number of industry firsts, including a radio coming fitted as standard and a full synchromesh gearbox being added a year later in 1935. By 1936 the straight Minx was accompanied by the Minx Magnificent, which did away with running boards and offered an improved chassis as well as an estate version to add to the body models of saloon, tourer and drophead coupe already offered across the range. 1938 saw the boldly-titled New Minx appear, albeit identical except for improved styling. Nevertheless, the Minx had taken a strong foothold in the market, with production swelling to nearly 60,000 units per year by the onset of war in Europe.


The postwar Mark I and Mark II Minxes profferred only minor updates to the range until 1947, when the Mark III brought fairly radical modernisations including a distinctly more modern rounded front than the Mark II with inset headlamps and a long, low front grille, as well as fundamental technical improvements such as hydraulic brakes. The 90,000 unit Mark IV took the Hillman Minx strongly into the fifties with a larger capacity engine at 1265cc. The style was kept consistent throughout the fifties, with the Mark V, Mark VI and Mark VII continuing the strong production run with only minor cosmetic changes. The last of this phase, the 1954 Mark VIII, adopted the 1390cc ohv engine that the next line of Minxes were to come with.

Audax Period

Considered by some to be the heyday of the Minx, the distinctly American-looking Audax body, designed in part by the great American designer Raymond Fernand Loewy, adorned the Series I from 1956 onwards. The Series II and Series III offered further styling adaptations as well as an upgraded 1494cc engine for the III. A flurry of models derived from the Series III - the Series IIIA, IIIB and IIIC brought further Americanisations, including tail fins, as well as a 1592cc engine for the "C-for-cheap" Series IIIC. Meanwhile, as the Minx Series carved its position as a no-nonsense entry level Rootes vehicle, the Super Minx of 1961 was aimed firmly at the top end of the family market, being more spacious and featuring more elaborate trim. The Super Minx was produced in parallel with the basic Minx until 1965, with the Series IV ending its relatively short production run. The Series Minxes continued to be made until '67, culminating in the Series VI, at which production was switched to the "New Minx" - another wonderful usage of the word "New" for what was basically a Rootes Arrow Hunter - with the last badged Minx rolling off the production lines in 1970.
