BAC (United Kingdom) - AllCarIndex

British Automotive Co. Ltd was a short-lived automobile manufacturer based in Chelsea, London, operating from 1921 to 1923. The company focused on producing light cars, with its prototype drawing inspiration from the MATHIS design. However, the production models utilized engines that were designed in Belgium and built in Britain, specifically the Peters engines, which came in two variants: a 1207 cc engine producing 9.5 horsepower and a 1498 cc engine generating 10.8 horsepower. Both engines were four-cylinder side-valve units, although attempts to convert them to overhead valve (OHV) configurations were reportedly unsuccessful.

The vehicles featured a four-speed Meadows gearbox and employed a shaft for final drive. The body styles offered included a two-seater with a dickey seat and a four-seater configuration. Production was limited, with estimates suggesting that no more than 20 units were manufactured during the company's brief existence. Notably, one of the employees at British Automotive Co. Ltd was W.G. Watson, who later gained recognition for his contributions to the automotive industry with brands such as Invicta and Lagonda.
