Austin

In September 1964 the Austin 1800 was introduced, additional badge-engineered Morris 1800 and Wolseley 18/85 variants were launched in 1966 and 1967 respectively. The car - code name ADO17 - was unconventional in appearance, being much wider and lower than most other cars in its class. The number and nature of technical issues affecting the early years of the Austin 1800 led to the realisation the car had been introduced with insufficient development. Nevertheless, the 1800 was voted European Car of the Year for 1965.

In May 1968 the Mk II was launched. It featured a cheaper and more conventional interior and a revised front grille. The slim, horizontal rear lights were replaced by vertical "fin" lights. The compression ratio was increased and maximum power output boosted by 5 hp to 86 hp. In October 1968, the 1800 S was launched, with a twin carburettor 95 hp engine.

In 1972 the Mk III was introduced. It featured a revised front grille and a number of interior improvements, including a conventional floor-mounted handbrake. The 2,227 cc straight-six cylinder engine used in the Australian Austin Tasman was introduced to form the Austin 2200. In March 1975 the cars were replaced by the new Austin 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.
