Named after the largest gem-quality rough diamond ever discovered, the Rolls-Royce Cullinan is a full-size luxury sport-utility vehicle, the first SUV to be launched by Rolls-Royce. The Cullinan's twin-turbo 6.7-liter V-12 provides 563 horsepower and is whisper quiet, lest it disturb the any special VIPs in the cabin. The engine is mated to a ZF eight-speed automatic transmission, which, via a link to GPS, anticipates upcoming road topography and pre-selects the appropriate gear. The "Off Road" button on the console, when pushed, will raise the Cullinan 40 millimetres on its air suspension.
