The Silver Cloud II was introduced in 1959.
It was little changed externally, but was given a new Rolls-Royce developed 6.2 L V8 engine, which pushed the weight to 2.11 tonnes.
Performance was greatly improved and top speed was raised to 183 km/h (114 mph), but the main improvements were in acceleration and torque.
Power steering became standard.
Electrically operated windows were now available as an option.

Although the improved performance of the new car was welcomed, commentators of the time noted that the V8-engined Silver Cloud II was neither as quiet nor as smooth as the straight-six-cylinder-engined Silver Cloud I, despite the new engine's hydraulic tappet operation.
 The new wet-linered V8 was also a little cramped in an engine bay intended originally for a narrower unit: in order to change the spark plugs it was necessary to remove the front wheel on the car's right side.
 There seems to have been a problem with crankshaft breakages in the earlier V8s: this was blamed on lack of lubrication to the bearings.

The basic architecture of the Silver Cloud II did not change between 1959 and 1963, but there were numerous minor changes implemented, notable among them a succession of improvements to the ventilation system.
 Interior changes in 1961 included the adoption of blue instrument lighting, the introduction of a combined indicator / headlamp flasher switch and of a handbrake warning light.
A remodelled rear light assembly was introduced in May 1962 and a change to single sealed-beam headlamps was made in August 1962.

The Motor magazine tested a Series II in 1960.
They recorded a top speed of 104.7 mph (168.5 km/h), acceleration from 0-60 mph (97 km/h) in 10.9 seconds and a fuel consumption of 13 miles per imperial gallon (22 L/100 km; 11 mpg‑US).
The test car cost £6092 including taxes.
