AC Sociable

The AC Sociable was the passenger version of the three-wheeled Auto-Carrier, the delivery tricar with which the firm that became AC Cars began production in 1904. Where the Auto-Carrier had a cargo box, the Sociable put a seat, so the same single rear wheel and chain drive carried a rider instead of goods. The single-cylinder engine was mounted just in front of the rear wheel, which contained a two-speed hub. A review of the 1912 Motor Cycle and Cycle Car Show called it one of the most popular cycle cars on the road, for pleasure and for business, and AC showed eight vehicles on its stand that year, six for pleasure and two for business. Advertisements from about 1911 often called it the Mighty Atom. It stayed in the range while the firm moved to Ferry Works at Thames Ditton and adopted its AC roundel.
