Tuesday 17th December 1991
The last Rolls Royce Phantom VI was completed, a Mulliner Park Ward laudaulette that was later sold to His Majesty Haji Hassanal Bolkiah Mu’izzaddin Waddaulah, the Sultan of Brunei. Based on the Phantom V, the Phantom VI had a re-styled fascia (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 limousines 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 6,230 cc (380 cu in) 90 degree V8 with a bore of 104 mm (4.1 in) and stroke of 91.5 mm (3.60 in) with twin SU carburettors, coupled to a 4-speed automatic gearbox. In a 1979 upgrade, engine capacity was increased to 6,750 cc (412 cu in), 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.
A total of 374 Phantom VIs were made. Unlike the Rolls-Royce 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.
