The Corniche, available as either a coupé or convertible, used the standard Rolls-Royce
V8 engine with an aluminium-silicon alloy block and aluminium 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), with a displacement of 6.75 L (6,750 cc/411 cuin). Twin SU
carburettors were initially fitted, but were replaced with a single
Solex 4A1 four-barrel carburetor introduced in 1977. De-smogged export models retained the twin SUs until 1980, when
Bosch fuel injection was added. A three-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 system as did Citroën, but without pneumatic springs, and with the hydraulic components built under licence by Rolls-Royce), at first on all four, but later on the rear wheels only. Four wheel
disc brakes were specified, with ventilated discs added for 1972. The car originally had a wheelbase of . It was extended to in 1974 and in 1979. The Corniche was different from other Silver Shadows in that it had exclusive half wheel covers with stainless steel trim (for brake cooling), a 3-spoke steering wheel with a wood rim, and Rolls Royce's first standard tachometer. The Corniche immediately became a status symbol for celebrities upon its release. Paul McCartney, Frank Sinatra and Tom Jones all bought one. David Bowie, Michael Caine, Elton John and Dean Martin put their names on two-year-long waiting lists. alloy and rubber
bumpers, an aluminium radiator, an oil cooler, and a bi-level air conditioning system. Later changes included a modified rear independent suspension in March 1979. In March 1981, after the Silver Spirit had gone on sale, the fixed-roof version of the Corniche and its Bentley sister were discontinued. The Bentley version was updated in July 1984 with a new name, the
Continental. It received revised and color-coded bumpers, rear view mirrors, a new dash, and improvements to the seats.
