The new 20 HP Rolls-Royce, sometimes called the “Baby Rolls,” arrived in October 1922 and was specifically intended for the owner-driver. Distinguished from the older and larger Silver Ghost by a mono-bloc engine design with an overhead valvetrain, it was also fitted with a detachable cylinder head and a coil-and-battery-type ignition system. Initially built with a three-speed centre-change gearbox, it later incorporated a four-speed, right-hand-shift unit in 1925. Although smaller and less expensive than the Ghost and Phantom, the Twenty nonetheless received custom coachwork from many of the finest coachbuilders of the era.
