The Phantom IV was the most exclusive Rolls-Royce model ever built and one of the most elite cars in the history of motoring. Only eighteen were made between 1950 and 1956, seventeen of which were sold - exclusively to royalty and heads of state. Sixteen are preserved in museums, public and private collections. == Characteristics == By creating the Phantom IV the manufacturer broke with their earlier decision to cease production of the series of "big" Rolls-Royce Phantoms after the end of the Second World War. The chassis differed from those of the shorter, production post-War models, the Rolls-Royce Silver Wraith and the Bentley Mark VI, apart from a larger size and an engine with increased capacity and power, in having an additional cross-member at the centre of the cruciform bracing and 10-stud road wheel mounting.〔Martin Bennett, "Rolls-Royce: The Postwar Phantoms IV, V, VI", p. 18, (2008)〕 The engine was a derivative of the 8-cylinder rationalized B range of petrol engines (formed by four, six and straight eight). Specifically it was a refined version of a B80, the last three of a B81, both used in military and commercial vehicles.〔(【引用サイトリンク】title=RREC - Rolls-Royce Enthusiasts' Club - Clan Foundry Belper )〕 The P. IV is the only Rolls-Royce motorcar to be fitted with a straight-8 engine, which was powerful but could also run long distances at a very low speed, an important feature for ceremonial and parade cars. All examples of this exclusive series were bodied by independent coachbuilders (in declining number after the war)〔Martin Bennett, "Rolls-Royce: The Post-War Phantoms IV, V, VI", p. 204, (2008)〕 and most of their bonnets surmounted by the kneeling version of the Spirit of Ecstasy, which had been unveiled in 1934 and used in various other models. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rolls-Royce Phantom IV」の詳細全文を読む スポンサード リンク
