The Rolls-Royce Silver Spirit is a full-size luxury car produced by Rolls-Royce Motors, in Crewe, England, from 1980 to 1997. It was the first model in the SZ series. The Silver Spur is a long-wheelbase version of the Silver Spirit, produced from 1980 to 2000. It was the first car to feature a retractable Spirit of Ecstasy. The spring-loaded mascot sank into the radiator shell if dislodged from its position. Mark I The Silver Spirit was introduced by Rolls-Royce in 1980 as the first of a new generation of company models. It formed the basis for the Flying Spur, Silver Dawn, Touring Limousine, Park Ward, and Bentley Mulsanne/Eight series. The Spirit/Spur carried over the basic design of the Silver Shadow, its 6.75 L L410 V8 engine and GM-sourced THM400 3-speed automatic gearbox, and similarly styled unitary bodywork manufactured at Pressed Steel. The Spur/Spirit continued the Silver Shadow's emphasis on ride quality by utilizing its hydropneumatic self-levelling suspension, modified with Girling automatic hydraulic ride height control system and gas-charged shock absorbers. Sealed beam headlamps were fitted in the United States due to longstanding regulations, while European laws allowed for the fitment of more modern composite units. Mark II The Silver Spirit II and Silver Spur II were refinements of the original models, introduced at the 1989 Frankfurt Motor Show. Suspension design saw the most change, with "Automatic Ride Control" introduced, a fully automatic system that adjusted dampers at all four wheels in real time. Other updates included the adoption of ABS and fuel injection as standard for all models and markets. The last Mark I Silver Spirit/Spur was chassis no KCH27798, with Mark II cars starting with 29001. The fuel injection system was now Bosch's MK-Motronic. Originally retaining the three-speed Turbo Hydramatic GM400 transmission from earlier Spirits/Spurs, a four-speed unit (the GM 4L80E) was introduced in the winter of 1991. The size of the petrol tank was also increased, up to , meaning that the car's range was now up to over . Exterior and interior changes were minimal, with a considerably smaller steering wheel and two additional ventilation outlets added to the fascia mildly modernising the look up front. Mark III The Silver Spirit III and Silver Spur III were introduced in 1993, featuring engine improvements and some cosmetic updates. A new design of intake manifold and cylinder heads increased power output. The parameters of the semi-active suspension system were
