The Rolls-Royce Silver Cloud I was introduced in 1955. The first of three series produced, the Silver Cloud I was built and engineered to be one of the best cars in the world. Fitted with a 4.9L inline six engine, the Silver Cloud I was built as a four door saloon, but coachbuilt convertibles and coupes were built by companies such as Mulliner Park Ward and James Young. The Silver Cloud I was offered until 1959 when it was replaced by the Silver Cloud II.
