Rolls-Royce’s first-ever SUV certainly deserves to be named after the largest gem-quality rough diamond ever found. The Cullinan embodies all of the British brand’s opulence in a larger-than-life package that wealthy families will find more practical. The turbocharged 6.75-litre V12 engine that motivates the Cullinan is available in two variants, one with 563 horsepower and the other producing 591 horsepower. Rear suicide doors make access to the fancy cabin easier.
