Background
Though always a company more concerned with smoothness, silence, refinement, and reliability than modernity, prior to WW2 Rolls-Royce and their cars were beginning to look unfashionably outdated even to a traditionally conservative clientele.
While the world rejoiced at the end of hostilities in 1945, Rolls suddenly faced a great surplus of manufacturing capacity, particularly at their Crewe facilities where Merlin V12 aero engines had been churned out in huge numbers during the war.
Fortunately, a solution would soon be found, and the company moved quickly to retool for production of an all-new and significantly modernized car that was first seen in 1946.
Rolls-Royce’s first post-war model, the Silver Wraith debuted late that year and employed a chassis similar to that of the Silver Dawn and Mark VI Bentley, though with a seven inch longer wheelbase at 10ft 7in.
The Wraith, however, was only intended for traditional coach built bodies rather than the Mark VI’s pioneering ‘standard steel’ bodywork.
Powering Rolls-Royce’s post-war range was a new 4,257cc six-cylinder engine of cast-iron, monobloc construction with an aluminium cylinder head featuring overhead inlet and side exhaust valves.
Only the bore and stroke dimensions were shared with the pre-war overhead-valve Wraith engine, the major advantage of this F-head layout being its large valves and generous water jacketing around the valve seats.
A four-speed manual gearbox with synchromesh was standard initially, an automatic option (for export models only at first) not becoming available until 1952, at which time the engine was enlarged to 4,566cc and a long-wheelbase (11ft 1in) version introduced.
Manufacture of the short-wheelbase Silver Wraith ended in 1952, with a total production of 1,144. The long-wheelbase version continued until the introduction of the Phantom V in 1959, by which time 639 chassis had been completed.
‘In a world of shattered monetary values and yet much-improved cars, the Rolls-Royce still stands alone. Perhaps the most striking general thought in considering this supreme machine today is that it has a name more universally honoured as a symbol of quality than that of any manufactured product,’ said The Autocar in 1949. And it’s still true 75 years later.
