By 1955, the automotive world was changing rapidly. The Silver Dawn, launched in 1949, was a roaring success, but it was built upon design principles conceived in the late 1930s, an issue that Rolls-Royce’s design team were aware of as early as 1947. Cue the introduction of one of the most transformative models in the history of the marque: the Silver Cloud.

The Rolls-Royce Styling Department, headed up by Ivan Evernden, recruited highly experienced designer John Blatchley in 1940. Blatchley originally joined Rolls-Royce from renowned London coachbuilder Gurney Nutting; unable to fight in the Second World War due to a heart murmur, he worked in the Aero Design headquarters at Hucknall, Nottinghamshire, where he was responsible for the cowling for Merlin engines used in Hurricane and Spitfire fighter aircraft.

Although Rolls-Royce suspended motor car production between 1939 and 1945 to focus on building aero engines, design work on a new model continued in the background. The new team launched the highly successful Silver Dawn in 1949, but in the background, work had already begun on a new model, one that would blend the modernised, ‘New Look’ style of the day with the elegance of traditional, British conservative design.

Under Evernden’s watchful eye, Blatchley, appointed to the newly created role of Chief Styling Engineer in 1951, conceived a quarter-scale model that same year, codenamed ‘Siam’. Seven prototypes later, the larger, full-scale Silver Cloud was born. Blatchley’s ingenious full-width body design, coupled with the inspired placement of chassis and mechanical components, allowed for a significant increase in cabin size. This in turn facilitated a grander, more luxurious seating and trim design.

It wasn’t just the cabin that grew in the new model; the wheelbase was lengthened by three inches (7.6 cm) – then by an additional four inches (10.2 cm) for the 1957 extended wheelbase version – while the straight 6-cylinder engine expanded to 4.9 litres of capacity. Even this enlargement didn’t occupy the engine bay entirely, though, which was purposely designed even larger to one day accommodate a V8 engine.

The upgrades didn’t stop there. The Design team’s engineers, overseen by Evernden and Blatchley, also made great strides with the chassis design, its welded box section yielding a torsional rigidity improvement of 46%. An automatic gearbox became a standard offering for the very first time, with power steering following in 1956. The Silver Cloud will forever be remembered as the last Rolls-Royce motor car to be offered both as a complete car and as a rolling chassis, upon which discerning clients could commission fully bespoke bodywork from specialist coachbuilders.

So successful was the Silver Cloud, Rolls-Royce produced two subsequent designs that bore the same name; Silver Cloud II, launched in 1959, would make full use of the enlarged engine bay with a formidable 6.2 litre V8 power unit, eliciting a 20% increase in engine power. While this version was largely unchanged to the previous on the outside, the Silver Cloud III received a considerable aesthetic facelift. Launched in 1962, the redesigned bonnet sloped forward to facilitate a reduced radiator height of around 1.5 inches (3.8 cm). Dual horizontal headlamps replaced the single units, while the sidelights were moved down from the top of the wing to the middle, incorporating one of the period’s great safety innovations – flashing turn indicators.

By 1965, Silver Cloud had run its course, replaced by the Silver Shadow. All three of its iterations were wildly successful in their own right, and the model is fondly remembered to this day; a beautiful example of a coachbuilt Silver Cloud III formed the centrepiece of Rolls-Royce Motor Cars’ annual presence at the world-famous Goodwood Revival earlier this year.

Such was the esteem with which former Chief Styling Engineer John Blatchley was held, he was consulted for his thoughts on Phantom VII in the early 2000s, when the marque was planning to relaunch at the new Home of Rolls-Royce in Goodwood. Rolls-Royce Motor Cars’ first Chief of Design, Ian Cameron, showed him a series of concepts for the new Phantom. Blatchley approved of just one: the same design that would go on to become Phantom VII.
