Three years in the making, the Rolls-Royce of SUVs has finally made its debut. Named after the largest rough diamond ever discovered, the Rolls-Royce Cullinan sits atop the ultra-luxury SUV segment with the Bentley Bentayga. The Cullinan uses Rolls-Royce's modular aluminum spaceframe and the company's twin-turbo V12. A host of novel features are included, like a cargo compartment separated from the cabin, suicide rear doors, and an automatic lowering system that drops the SUV 1.5 inches when the driver approaches. Rolls-Royce's Bespoke division also offers a Recreation Module, with each one being tailored to the buyer's interests. Deliveries of the Cullinan will begin in 2019.
