PredecessorSilver Ghost

The Rolls-Royce Phantom was

overhead valves instead of the Silver Ghost's side valves
.

The Phantom was built in Derby, England, and 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. The designation Phantom I was never used by Rolls-Royce; it is a construct of enthusiasts applied to help distinguish it from other generations with the same model name.

Name

Introduced in 1925, the New Phantom was Rolls-Royce's second

BMW Group, New Phantoms were referred to as such in period and are commonly called Phantom I by enthusiasts, concours events, and owner's clubs.[4]

Drivetrain

One major improvement over the Silver Ghost was the new

straight-6 engine.[4][5] Constructed as two groups of three cylinders with a single detachable head,[4] the engine was described by Rolls-Royce as producing "sufficient" power.[5] The engine used a 4+14 in (108.0 mm) bore and undersquare 5+12 in (139.7 mm) stroke for a total of 7.7 L (7,668 cc (467.9 cu in)) of displacement. In 1928, the cylinder heads were upgraded from cast iron to aluminium; this caused corrosion problems. The separate gearbox connected through a rubberised fabric flexible coupling to the clutch and through a torque tube enclosed drive to the differential at rear, as in the Silver Ghost.[citation needed

Chassis

The New Phantom used the same frame as the Silver Ghost,[4] with semi-elliptical springs suspending the front axle[6] and cantilever springs suspending the rear axle.[6][7] Four-wheel brakes with a servo-assistance system licensed from Hispano-Suiza were also specified,[4][5][8] though some early US models lacked front brakes.[citation needed]

Differences between US and UK versions

Like the Silver Ghost, the New Phantom was constructed both at Rolls-Royce's Derby factory in the United Kingdom and at a factory in Springfield, Massachusetts in the United States.[4][5] The US factory produced New Phantoms from 1926 to 1931.[5]

Principal differences between the US and UK models included wheelbases and transmissions. Both versions were specified with the same standard 143+12 in (3,645 mm) wheelbase; the long-wheelbase U.S. model was 146+12 in (3,721 mm) and the UK 150+12 in (3,823 mm).[citation needed] Both versions used a single dry-plate clutch,[citation needed] with US models equipped with a centre change 3-speed transmission and UK a 4-speed.[5]

Other minor differences include fuel gauge placement, with the UK New Phantom's at the tank but some US models having one on the dash, and manual central lubrication systems. The UK Phantom employed Enots nipples, some times as many as 50, which required attachment of a special Enots oil pressure gun and needed time-consuming service at 500, 1000 and 2000 mile intervals;[citation needed] the US model used a centralized Bijur system which lubricated all the oiling points with a stroke of a single pump.[6]

Coachwork

Only the chassis and mechanical parts were produced by Rolls-Royce. The body was made and fitted by a coachbuilder selected by the owner. British coachbuilders who produced bodies for New Phantoms included Barker, Park Ward, [Windovers], Thrupp & Maberly, Mulliner, Hooper. Continental houses such as Saoutchik, Henry Binder and Kellner in Paris, Erdmann and Rossi in Berlin, Baltasar Fiol in Spain, Nordberg in Sweden and the Italian coachbuilder Zagato also produced coachwork for the New Phantom, just to name a few. Despite the availabilty of a US-built chassis, a handful of British-made Phantoms were outfitted with American coachwork.

American Phantoms could be bought with standardized bodies from

Huntington Limousine, Henley Convertible, Avon Sedan, Newmarket Convertible Sedan, Chatsworth Town Car, and the French city of Trouville Town Car. A convertible sedan with coachwork from Hibbard & Darrin was also offered, as were other French-made bodies by the same coachbuilder. They were shipped to the United States and subsequently mounted on Springfield Phantom chassis.[1]
