The 10 HP model of 1913 used a French engine, the Fivet, which had a very food weight/power ratio. After the war this was discarded in favor of the English Anzani engine, and the price of the car rose to ?560. The first models incorporated a cone clutch, which proved very unsuitable for such a light vehicle. This problem was solved, however, when Weller became one of the first men, if not the first , to use a disc clutch in a motor car, although it should be noted that the A.C. Company never claimed that it was the first to do this. The speed of the 10 HP model was about 45 mph.

The 6-cylinder model made its debut at the London Salon of 1919. The overhead valves, remained in production until 1963, a unique case in the history of the automobile. Its main advantage was its relative quietness. From its original 40 bhp the power of the engine was gradually increased to 85 bhp. A.C. changed its name four times during its history, though always keeping those initials, which stood for Auto Carrier at the time of the company’s creation. In 1904 it became Autocars and Accessories, changing in 1911 to Autocarriers Ltd, and in 1922 to A.C. Ltd.
