Rolls-Royce Phantom I .......

The Phantom was Rolls-Royce's replacement for the original Silver Ghost. Like the famed Ghost, the Phantom was constructed both in the United Kingdom and United States, with the US model trailing the UK by one year on introduction and two in replacement.

One major improvement over the Silver Ghost was the new pushrod-OHV straight-6 engine. Constructed as three groups of two cylinders with detachable heads (state of the art at the time), the large engine produced excellent power to pull the large heavy car. The engine used a 4¼ in (107.9 mm) bore and long 5½ in (139.7 mm) stroke for a total of 7.7 L (7668 cc/467 in³) of displacement. Aluminum was substituted for cast iron in the cylinder heads in 1928.
