In the 10s of the 20th century, the Rolls-Royce range was significantly simplified to virtually one model, the 40/50, which would later become the Silver Ghost. After World War I, the 40/50 Silver Ghost went into production, with a 7410cc inline 6-cylinder engine. Many coachbuilders designed beautiful configurations for this car, which remained in production until 1925, when it was replaced by the first generation of the Phantom.
