1903 The first AC car was presented at the Crystal Palace motor show in 1903; it was a 20-hp touring car and was displayed under the Weller name. The Weller Brothers in West Norwood, London, planned to produce an advanced 20-hp car. However, Portwine, their financial backer thought the car would be too expensive to produce and encouraged Weller to design and produce a little delivery 3 wheeler. Weller did so, called it the Auto-Carrier and a new company was founded and named Autocars and Accessories
1904 Production started - the three-wheel vehicle caught on quickly and was a financial success. This used a single cylinder engine and had tiller steering.
In 1907 a passenger version appeared, it was called the Auto-Carrier Sociable. It had a seat in place of the cargo box.

1919 After the war, John Weller started on the design of a new 6 cylinder motor. The first versions were running by 1919. The Weller motor would be produced until 1963; it is probably the second longest running production motor in history after the VW boxer. During the 1914-18 War, the Ferry Works factory produced shells and fuses, although at least one vehicle was designed and built for the War Office. At the end of the First World War, AC Cars started making motor vehicles again, designing and building many successful cars at Ferry Works.
1922 Selwyn Edge gained full control of the company. Name changed to AC Cars Ltd.
1926 Full production of the six-cylinder engine.
1927 Ceased production of the four-cylinder engine.
1927 Selwyn Edge bought the company outright for £135,000 and re-registered it as AC (Acédès) Ltd but sales, which had been falling, continued to decline.
1929 The company was caught by the crash of 1929 and went into voluntary liquidation.
In 1930 production ceased and the company was sold to the Hurlock family who ran a successful haulage business. Became a private company. They wanted the factory as a warehouse but allowed the service side of AC to continue.
A single car was made for William Hurlock in 1930. He agreed to a very limited production restarting mainly using components left over from previous models. Agreement was reached with Standard to supply new chassis and in 1932 a new range of cars was launched. Production remained on a small scale until the outbreak of war in 1939.
WWII Produced motorised invalid chairs, fire-engines, aircraft parts and guns.
1947 Production of cars restarted after a break of eight years with the 2 litre Saloon, Coupe and Tourer and with a large contract with the government to make glass fibre bodied single seat invalid carriages with BSA engines. These continued to be made until 1976 and were an important source of revenue to the company. They also built an aluminium bodied three wheeled micro car, the Petite.
1951 Became a public company with £100,000 capital. 
1951 Exhibitor at the 1951 Motor Show in the Car Section.
In 1953 the firm began production of the AC Ace, a lightweight chassis designed by John Tojeiro with the venerable AC Weller 2 litre engine.
