Background
Ironically World War I helped make the Silver Ghost (or 40/50 h.p. as it was officially named) an iconic Rolls-Royce model in a number of unforeseen ways. Firstly, by extending its life thanks to a wartime pause in production, lending it a tenure extending from 1906 to 1926. Then there were its heroics and derring-do during the war itself. As well as providing transport for the King’s Messengers during the war, the chassis and engines of the Silver Ghost provided the underpinnings for Britain’s preeminent armoured cars of the time. Lastly, an armistice related deal led to a Rolls-Royce factory being established in Springfield, Massachusetts and the Silver Ghost being the first Rolls-Royce to be built outside of the sceptred isle.
Despite all that, not even the Silver Ghost could shake off the ravages of time and by 1922 sales had dropped dramatically. A replacement was needed, and it appeared in 1925 in the form of the New Phantom. It was only at this stage that Rolls-Royce recognised the Silver Ghost name applying it retrospectively to the 40/50 h.p. and the “Phantom I” name only being applied (but never by Rolls-Royce themselves) once the Phantom II arrived.
Whilst much was carried through from the earlier car, the main differences lied under the centre-hinged bonnet. A new, inline six-cylinder engine lived here with overhead pushrod valves and displacing a mighty 7,688cc. Four-wheel brakes with a servo-assistance system licensed from Hispano-Suiza was now used. In traditional Rolls-Royce fashion, only the chassis and mechanical ancillaries were produced by the company in Derby (and, again, in Springfield). It was incumbent on the buyer to select a coachbuilder to produce the body. Popular choices included Park Ward, Mulliner (Park Ward and Mulliner would eventually merge in 1961) and Hooper.
