Rolls-Royce Phantom VI  The Phantom VI is a British ultra-exclusive rolling chassis made from 1968 to 1990. From 1968 to 1973 it was manufactured by Rolls-Royce Ltd, and 1973 to 1990 by its successor Rolls-Royce Motors. Based on the Phantom V, they were primarily bodied as limousines, along with a few landaulettes. Fundamentally an updated Phantom V, the Phantom VI had a restyled dashboard and was powered by an engine derived from the current Rolls-Royce Silver Shadow. Most of the coachwork was created by Mulliner Park Ward, usually in limousine form, though a few landaulettes were made. The Phantom VI was the last Rolls-Royce with a separate chassis. It featured coil springs in front, leaf springs and live axle in rear, and drum brakes on all four wheels. The car was powered by a 90-degree V8 with a bore of and stroke of with twin SU carburettors, coupled to a 4-speed automatic gearbox. In a 1979 upgrade the engine capacity was increased to , a 3-speed automatic gearbox with torque converter was substituted, and separate front and rear air conditioning units were provided. Inclusion of the engine from the Rolls-Royce Silver Spirit in 1982 increased engine displacement once more, to 6,750 cc. In 1990 the last Rolls-Royce Phantom VI chassis were built, however as the completion of the coachwork by Mulliner Park Ward took around 18 months the last cars were made in the period of the next two years. The very last Rolls-Royce Phantom VI, a landaulette, was completed and delivered to the customer in summer of 1992. A total of 374 Phantom VIs were made. Unlike the Phantom V, they were never sold in the United States, due to United States Environmental Protection Agency and National Highway Traffic Safety Administration design legislation. Design of a Phantom VII based on the Silver Shadow's body was discussed in the 1970s, but plans were scrapped. No prototypes were built. A production Rolls-Royce Phantom VII was rolled out in 2003. Within the fleet of cars used by Queen Elizabeth II and her family in the United Kingdom are two Rolls-Royce Phantom VIs: the Silver Jubilee Car (presented by the British motor industry to celebrate her 25th anniversary on the throne in 1977), and a more conventional 1986 model. These two cars were the official state cars until the introduction of the two Bentley State Limousines in 2002.
