Soon to be seen pulling up to red carpets everywhere is Rolls-Royce's very first SUV, named after the largest diamond ever found. Sporting rear-hinged suicide doors and an opulent cabin, the Cullinan commands a starting price around $327,000—and for good reason. Its twin-turbo 6.8-liter V-12 provides 563 effortless horsepower and runs as whisper-quiet as you would expect, lest it disturb the VIPs in its cabin. Rolls-Royce estimates a zero-to-60-mph time of just 4.8 seconds.
