BSA cars were manufactured between 1907 and 1912 in Birmingham then until 1939 in Coventry as well as Birmingham, England.  BSA had established a motor-car department in an unsuccessful effort to make use of the Sparkbrook Birmingham factory.  An independent part of the same site was occupied by The Lanchester Motor Company Limited.  Sales were handled by BSA Cycles Limited.  After 1912, manufacture was carried out by group subsidiary Daimler in Coventry or BSA Cycles in Birmingham.

​

The first prototype car was produced in 1907.  The following year, marketed under BSA Cycles Ltd, the company sold 150 automobiles and again began producing complete bicycles on its own account.  By 1909, it was clear that the new motorcar department was unsuccessful, an investigation committee reporting to the BSA Board on the many failures of its management and their poor organization of production.
