The model was assembled and finished in London at Mulliner Park Ward as continuation of the 1965 Silver Shadow coupe and 1967 drophead, with the Corniche name applied in 1971. The Corniche was also sold as a Bentley, though that model became known as the Continental in 1984. The first car to wear the Corniche name was a 1939 prototype based on the Bentley Mark V which was never produced because of the onset of World War II.

The Corniche was available both as a coupé and convertible, with the former discontinued in 1982.

The car used the standard Rolls-Royce V8 engine. It had an aluminium-silicon alloy block and aluminum cylinder heads with cast iron wet cylinder liners. The bore was 4.1 in (104.1 mm) and the stroke was 3.9 in (99.1 mm) for a total of 6.75 L (6750 cc/411 in³). Twin SU carburettors were initially fitted with a single Solex 4-barrel carburettor introduced in 1975. Export models retained the twin SU's until 1980, when Bosch fuel injection was added.

A 3-speed automatic transmission (a Turbo Hydramatic 400 sourced from General Motors) was standard. A four-wheel independent suspension with coil springs was augmented with a hydraulic self-levelling system (using the same Citroen system, but without pneumatic springs, and hydraulic components built under licence by Rolls-Royce), at first on all four, but later in the rear wheels only. Four wheel disc brakes were specified, with ventilated discs added for 1972.

The car originally used a 119.75 in (3042 mm) wheelbase. This was extended to 120 in (3048 mm) in 1974 and 120.5 in (3061 mm) in 1979.
