The Phantom was Rolls-Royce's replacement for the original Silver Ghost. Introduced as the New Phantom in 1925, the Phantom had a larger engine than the Silver Ghost and used pushrod-operated overhead valves instead of the Silver Ghost's side valves. The Phantom was built in Derby in England and in Springfield, Massachusetts in the United States. There were several differences in specification between the English and American Phantoms. The Phantom was replaced by the Phantom II in 1929, at which point it was called the Phantom I.
