As Rolls-Royce’s first and only sport utility vehicle, the ultra-luxurious Cullinan is motivated by a twin-turbocharged 6.75-litre V12 engine that produces 563 horsepower. Shifting duties are handled by a nine-speed automatic transmission mated to an all-wheel drive system. The Cullinan further stands out with suicide rear doors and optional cargo-area seats that pop up when you open the liftgate. By the way, the name of this SUV comes from the largest rough diamond ever discovered.
