The car, which had the design code ADO71, was originally marketed as the Austin / Morris / Wolseley 18–22 series. Ahead of the October 1975 London Motor Show the range was rebranded "Princess". This was effectively a new marque created by British Leyland, although the "Princess" name had previously been used for the Austin Princess limousine from 1947 to 1956, and the Vanden Plas Princess. The Princess is often referred to, incorrectly, as the Austin Princess. Although this name was not used in the UK market, it was used in New Zealand. The car was later revamped as the Austin Ambassador, a hatchback, which was produced from 1981 until 1984 and only available in Britain and Ireland.
