Alliott Verdon-Roe's Avro aircraft company was one of the major suppliers of combat aeroplanes during World War I, and, like so many others, turned to the motor industry to keep at least some of the workforce in employment. They made Avrolite bodies for Model T Fords, and announced their own car in 1919. This had an integral construction body/chassis with a light timber framework panelled in aluminium. A variety of engines was tried in several experimental cars, including a 1330cc four, a single-cylinder 2-stoke and a 5 cylinder radial. It was said that a Model T engine was used in one prototype, which is not surprising, considering Avro's bodybuilding links with Ford, and that Ford's Trafford Park factory was not far away from the Avro premises. However, it is unlikely that any of these cars actually reached the market place. The same can be said for Verdon-Roe's 2-wheeled monocars, which were intended to provide more civilised and weatherproof transport than a motor cycle. He made at least two, one with a Barr & Stroud 2-stroke engine in 1923, and another with 350cc Villiers engine in 1927. They were probably inspired by the Harper Runabout, which was made in the Avro factory from 1921 to 1926.
