''For information on the Silver Wraith II, see Rolls-Royce Silver Shadow.'' The Silver Wraith was the first post-war Rolls-Royce. It was made from 1946 to 1958 as only a chassis at Rolls-Royce's former Merlin engine plant, their Crewe factory, alongside the shorter Bentley Mark VI. The Bentley was available as a chassis for bespoke coachwork but also could be bought with a standard steel body. It was announced by Rolls-Royce in April 1946 as the 25/30 hp replacement for the 1939 Wraith in what had been their 20 hp and 20/25 hp market sector, that is to say Rolls-Royce's smaller car. The size was chosen to be in keeping with the mood of post-war austerity. Even very limited production of the chassis of the larger car, their Phantom, was not resumed until 1950 and then, officially, only for Heads of State.〔Peter Pugh ''The Magic of a Name: The Rolls-Royce Story, Part 2: The Power Behind the Jets'' 2015 Icon Books. ISBN 1848319630, ISBN 9781848319639〕 Improvements announced were: chromium plated cylinder bores for the engine; a new more rigid chassis frame to go with new independent front suspension and a new synchromesh gearbox. Chassis lubrication was now centralised.〔News in Brief. ''The Times'', Thursday, Apr 04, 1946; pg. 2; Issue 50418〕 ==Engine== The straight six-cylinder postwar engine, which had been briefly made for the aborted by war Bentley Mark V, replaced conventional overhead valve gear with an F-head configuration of overhead inlet valves and side exhaust valves and reshaped combustion chambers. There were new main and big-end bearings and a more efficient drive to the timing gear. To this prewar mix Rolls-Royce added chromed bores. Initially, this engine retained the Mark V's capacity of 4257 cc. increased from 1951 to 4566 cc and in 1955, after the introduction of the (standard wheelbase) Silver Cloud, to 4887 cc for the remaining Silver Wraiths. 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 Silver Wraith」の詳細全文を読む スポンサード リンク
