SERIES I AND II
The Series I Minx was built from 1956 to 1958 and included saloon (sedan), convertible and estate (station wagon) models . It was a comlpetely new design from the previous Mark Minx which was in production from 1948 to 1956. It became known as the "Audax" (Latin for bold) style of Minx and was designed by the Raymond Loewy studios who were also responsible for the design of the early 1950's Studebakers. Features included a unit body (monocoque) design, 4 cylinder ohv in line engine of 1,390cc displacement, 4 speed gearbox with no synchromesh on 1st gear and a steering column gearchange.
The Series II was essentially the same car with the exception of a slightly revised front grill, the option of a floor mounted gear change on the Minx Special and the availabilty of a Manumatic semi automatic transmission.

SERIES III, IIIA AND IIIB
The next three Series of the Hillman Minx were produced from 1958 until 1961. For the Series III the engine capacity was increased to 1,494cc from the previous 1,390cc. Also a new grill and interior facia panel were fitted. Available models included two saloons, the Special and De-Luxe, an estate and a convertible.
The IIIA introduced a year later in Sept. 1959 sported the following changes: the Manumatic transmission option had now been replaced with the brand new Smiths Easidrive fully automatic gearbox, engine horsepower had been slightly increased, a floor mounted gear shift was standard (on UK models only) and most noticeably small roll over fins had been added to the rear fenders. Models available were the same as with the Series III Minx.
The Series IIIB offered no visible difference in styling with the main changes being the inclusion of a new genereation of hypoid-bevel rear axle (replacing the original spiral type) and a larger windshield. Model range the same with the exception of the Special which was renamed the Standard Saloon.

The Series IIIC was the next model, introduced in August 1961 and continuing in production until 1963. The engine was enlarged to a capacity of 1592cc from the previous 1,494cc. Exterior changes being limited to the following: Minx script was taken off the front doors and put on rear of car and the double side strips of chrome were replaced by one single strip. There was only one version of the saloon offered as the basic Special version had been discontinued. Also both the estate and the convertible models were discontinued from mid 1962 reducing the line to only the one four door saloon model. This simplification of the line was done to make way for the new Hillman Super Minx.
Rootes also started marketing this model as the Minx 1600 replacing the previous door positioned Minx script with new 1600 badging.

SERIES V AND VI
There was no Series IV Minx as this designation had been given during development to the car which eventually became the Hillman Super Minx. The Super Minx was to replace the Existing "Audax" Hillman Minx line after the Series IIIC and was to be the new Hillman Minx Series IV. Lord Rootes apparently felt it unwise to drop the original smaller model Minx which was the Rootes Group's best selling model so the next Hillman Minx bore the Series V model number.
The Series V Minx sported a completely restyled interior plus the tail end of the car had been redesigned as well, losing the roll over fins in the new treatment. Other changes were apparent on the exterior of the car as well. The upper cabin roof had a flatter profile than the previous rounded roof plus larger rear doors and the wraparound rear window had been replaced by a less rounded one. Also fitted were 13 inch wheels (replacing the previous 15 inch ones) as well as front disc brakes. The Borg- Warner automatic transmission was now offered as an option replacing the troublesome Smiths Easidrive and full sychromesh was offered on the manual gearbox from autumn 1964.
The Series VI Minx was identical to the previous Series V model except that the old 1592cc three bearing engine was replaced with it's newer 1725cc five bearing version. The only exterior difference was the addition of '1725' badging to denote this change.
The Series VI was the last of the Audax style of Hillman Minx being discontinued in early 1967 in favour of the new Arrow style range of Minx.
