The Phantom II replaced the New Phantom in Rolls-Royce's offerings in 1929. The Rolls-Royce Phantom II was the last of the great six-cylinder cars whose development from first draft to completion had entirely been supervised by Mr. F. Henry Royce himself. Incorporating radical design changes from its predecessor, the Phantom I, the new car took the company into the new decade. The engine was unitary with a four-speed manual transmission. Synchromesh was added on gears 3 and 4 in 1932 and on gear 2 in 1935.
When launched in 1929 it impressed by surpassing every facet of design excellence and manufacturing technique, even those embodied in the Silver Ghost. The engine and gearbox were of unit construction. The rear springs were now underslung, replacing the previous cantilever suspension - thus enhancing the mounting of the most elegant bodies to a lower overall appearance. The front axle was designed to provide ultimate stability in braking at speed. As a more sporty version to be fitted with particularly light coachwork, the Phantom II Continental distinguished itself from the basic model.
Semi-elliptical suspended the front and, in a change from its predecessor, the rear. Four-wheel servo-assisted brakes were also specified. Only 281 Continental Phantom II's were produced, including 125 left-hand drive versions. In all, 1,281 Phantom II chassis left the factory.
