Austin Twenty is a large car introduced by Austin after the end of the First World War in April 1919, and continued in production until 1930. After the Austin 20/6 model was introduced in 1927, the first model was referred to as the Austin 20/4.

Before 1919, Austins had been expensive, prestige cars. In the 1920s there were people who believed the four-cylinder Twenty comparable with, if not superior to, the equivalent Rolls-Royce. If the coachwork were light enough, the Twenty could also give a three-litre Bentley a run for its money. The final inter-war version was the enormous, extremely elegant, fast and powerful side-valve Twenty-Eight of 1939. The overhead-valve (25) Sheerline and its Princess companion were to continue the line after the Second World War; however, by the 1930s Austin had lost its aristocratic cachet, having become well known for its Twelves and Sevens.[4]

The deceptively potent four-cylinder Twenty found fame at Brooklands both in private hands and with works drivers Lou Kings and Arthur Waite (Herbert Austin's Australian son-in-law and competitions manager).[4]
