This famous Yorkshire aircraft firm, like so many others ventured into car manufacturer after World War I, when war-time contracts ended and the aircraft market virtually disappeared. Rather surprisingly, however, they produced a very conservative car when other aircraft manufacturers were adapting aviation experience to the road. The engine of the Blackburn was a big 4-cylinder Coventry-Simplex of 3160cc, its cylinders cast in pairs, although a monobloc was introduced for 1922. The gearbox was separate, and a cone clutch was used. The radiator was a copy of the Rolls-Royce, a common practice of the time. Blackburn also mae bodies for ther car markers.
