Originally named the “40/50 h.p.” the chassis was first made at Royce’s Manchester works. Chassis no. 60551, registered AX 201, was the car that was originally given the name “Silver Ghost.” Other 40/50 hp cars were also given names, but the Silver Ghost title was taken up by the press, and soon all 40/50s were called by the name. The Silver Ghost was the origin of Rolls-Royce’s claim of making the “best car in the world” – a phrase coined not by themselves, but by the prestigious publication Autocar in 1907. The chassis and engine were also used as the basis of a range of Rolls-Royce Armoured Cars.
