The Austin A50 Cambridge was a British four-door saloon produced by the Austin Motor Company during the mid-1950s, representing a mid-range family car in Austin's postwar lineup. It was introduced in 1954 as a development of the earlier A40 Cambridge, featuring a 1,489cc B-series engine and a body style shared with related BMC models of the period. The A50 was notable for its use of the BMC B-series engine, which went on to power a wide range of British vehicles across several decades. Variants included the Countryman estate body style, which broadened the model's appeal to buyers requiring additional load-carrying capacity.
