Rolls-Royce's new limousine model, the long-wheelbase Rolls-Royce Phantom V effectively replaced both the royalty / heads of state-only Phantom IV and the Silver Wraith. The latter's relatively short wheelbase had made it all but impossible for coachbuilders to provide adequate boot space in a comfortable seven-seater, a shortcoming addressed by the new Phantom V. Built on a much modified and strengthened Silver Cloud chassis, enjoying the same 12' 1'' wheelbase as the Phantom IV, the new Phantom measured 19' 10'', some 11'' longer than the Phantom IV, enabling coachbuilders to combine the desirable qualities of spacious interior accommodation with generous boot space and graceful lines. A lower final drive ratio ensured that the new car would match its stablemates for acceleration, with over 100mph still possible.Rolls-Royce's in-house coachbuilder Mulliner Park Ward produced a preferred seven-passenger limousine coachwork for the Phantom V, the usual upholstery to front being in leather, also listed as an option to rear, along with West of England Cloth. A cocktail cabinet was standard while all-round electric windows and separate air conditioning to front and rear were among preferred options.
