Up until 1957 Bentley had only offered two door Continental style bodies, so to meet the demand of requests from their customers for a more practical four door variant with greater luggage capacity the Flying Spur was born. H.J.Mulliner s chief designer George Moseley was entrusted with styling the new four door motor car and his design was so well received that it lasted the entire production of S Type Bentleys until 1966, also becoming one of the coachbuilt options available on the Rolls-Royce Silver Cloud III chassis.
