Rootes Group
In 1928, Hillman fell under the control of the Rootes brothers and then merged with Humber. The Rootes brothers obtained further backing from Prudential Assurance during 1931 and brought their holding up to 60 per cent of Humber. Then, in stages, Hillman was switched to manufacturing small cars and became the best known brand within the Rootes empire alongside Humber, Sunbeam and, in the Rootes Group's final decade, Singer.
The 1930s saw a return to side valves with a 6-cylinder Wizard first produced in April 1931 and, in 1932, inspired by the Rootes brothers, the first car to carry the Minx name. This had a 1185 cc four-cylinder engine and went through a series of updates in body style and construction until the end of the Second World War. In 1934 the Hillman Wizard "65" and "75" were replaced by the 2110 cc Hillman "16 hp" and 2810cc "20/70", which lasted until 1936 when a new body design in the form of the 2576 cc Hillman "Sixteen" and the 3181 cc "Hawk" and "80", all with side valve straight-six engines, were introduced. These later cars were also sold as Humbers.
After the war, the Minx was reintroduced with the same 1185 cc engine. It went through a series of models given Phase numbers and the Phase VIII of 1955 saw the arrival of an overhead-valve engine 1390cc, the Mk 8. The later 1956 Two Tone version of this model, the Mark 8A, was called the "Gay Look" and led to the advertising slogan "As Gay as a Mardi Gras". A smaller car, the Husky with van like body and using the old side-valve engine, was also new for 1954. The floor pan of this model was later to form the basis for the Sunbeam Alpine, Sunbeam also being part of the Rootes empire. A complete departure in 1963 was the Hillman Imp using a Coventry Climax derived all alloy, 875 cc rear engine and built in a brand new factory in Linwood, Scotland. The location was chosen under government influence to bring employment to a depressed area. A fastback version, the Californian, and an estate re-using the Husky name were also made. A new car called the Hunter was introduced in 1966 with, in 1967, a smaller-engined standard version using the old Minx name. These are frequently given their factory code of "Arrow", but this name was never officially used in marketing.
Peugeot
The Avenger and Hunter ranges were badged as Chryslers from 1976 until 1979, when Chrysler sold its European division to Peugeot. At this point, Hunter production was shelved and the Avenger was rebadged as a Talbot until it was finally withdrawn from sale at the end of 1981.
Hillman's Ryton factory, which had assembled various Peugeot models for the European market, closed in 2007. The French company still owns the rights to the Hillman name.
