1924 Rolls-Royce 20 HP

After the First World War, Rolls-Royce built a supplemental version of the Silver Ghost which was codenamed the Goshawk. It was designed to appeal to a wider audience where the owner drove their own car. Introduced in 1922, the Twenty was remarkably successful thanks in part to the prevailing economic conditions of the day. Power was from a six-cylinder monobloc engine that had a little over 3-liters in displacement, a one-piece detachable cylinder head, and overhead valves (a first for a Rolls-Royce engine). Initially, the Twenty was fitted with a three-speed center-change gearbox. From 1925 onwards, it used a four-speed unit, along with all-wheel brakes. It had a 129-inch frame with semi-elliptic suspension front and rear. They were well suited for lighter touring coachwork, although some owners selected the additional weight of sedancas, landaulettes, and limousines. Total production reached 2,885 examples before its replacement, the 20/25, was launched in 1929.
