Rolls Royce Phantom 1 History
Like the famed Ghost, the Phantom 1 was constructed both in the United Kingdom and United States, with the USA model trailing the UK by one year on introduction and two in replacement.
One major improvement over the Silver Ghost was the new pushrod overhead valve straight-6 engine. Constructed as three groups of two cylinders with detachable heads very modern and state of the art technology for the time, the large engine produced excellent power to pull the large heavy car. The engine used a 4¼ inch bore and long 5½ innch stroke for a total of 7.7 Litres of displacement. Aluminum was substituted for cast iron in the cylinder heads in 1928.
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. Differences between the US and UK models included available wheelbases, both were specified with the same 143½ inch base length, but the UK long-wheelbase model was longer at 150.5 inch than the 146.5 inches American version. Other differences included the Gear box, with UK models using a 4-speed and American models using a 3-speed Manual Gearbox, both with a single dry-plate clutch. UK models were built at Rolls' Derby factory, while US Phantoms were built in Springfield, Massachusetts.
