Rolls Royce Silver Cloud III

Rolls Royce, after the end of the Second World War, has been manufacturing its renowned best model until nowadays. The Silver Cloud. With this new model, Rolls Royce could build the bodyworks of its cars obtaining first level models as the Phantom IV, a representative limousine that closed the range of models offered by Rolls Royce.

These new models were already equipped with inline-six/ eight cylinder engines, that offered between 125 y 175 horsepower, achieving the development of new prototypes that during 1955 were baptized as Rolls Royce Silver Cloud and Bentley S-Type.

Towards the end of the 50’s the second series of the Silver Cloud and S-Type were already known. They were differentiated from the previous version as they had a modern eight-cylinder engine in V completely made of aluminum.

In 1962 the Silver Cloud III was launched, with two models of different main frame lenght: normal and extended (LWB). This third edition of Silver Cloud included new technologicals changes such as its screwed up bodywork, its drum brakes and independent suspensions, among other details.

Nowadays, after more than 50 years the Silver Cloud III is still a synonim of glamour and elegance as it can be enjoyed not only for its excellent driving experience but also for its doors and upholstery, frames of make-up rear mirrors and all the category details that this model offers.
