Full description
The Phantom was Rolls-Royce's replacement of the original Silver Ghost. Like the famous Ghost, the Phantom was constructed both in the United Kingdom and the United States. The model produced in the United States had over a year delay in terms of introduction and two years in terms of production, compared with the one assembled in the United Kingdom.
One major improvement over the Silver Ghost was the new 6-cylinder - OHV engine. Constructed, as what was state of the art at the time, of three groups of two cylinders with detachable heads, the large engine produced excellent power to pull the large heavy car. The engine used a 4¼ in (107.9 mm) bore and 5½ (139.7 mm) stroke for a total of 7.7 L (7668 cc/467 in³) displacement. In 1928, the cylinder heads were upgraded from cast iron to aluminium.
Semi-elliptical springs suspended the front, while cantilever springs were used in the rear. 4-wheel servo-assisted brakes were also specified, though some initial US models lacked front brakes.
The differences between the US and UK models included available wheelbases — both were specified with the same 143½ in (3644.9 mm) base length, but the UK long-wheelbase model was longer 150½ (3822.7 mm) in comparison with the American version of 146½ (3721.1 mm). Other differences included the transmission - the UK models used a 4-speed manual transmission, while the US models used a 3-speed one, both with a single dry-plate clutch.
The UK models were built at Rolls' Derby factory, while US Phantoms were built in Springfield, Massachusetts.
