Its first-ever SUV became its best-selling model and a fashion accessory for one-percenters. It’s powered by an effortless twin-turbo V-12 engine and floats on an adjustable air suspension. The cabin is pure bliss, with supremely comfortable seats and generous passenger space. The environment can be enhanced even further with myriad personalization options. Without doubt, the 2020 Rolls-Royce Cullinan is the fanciest SUV on the planet, and that’s why it costs a small fortune. Its twin-turbo 6.7-liter V-12 provides 563 effortless horsepower and runs as whisper-quiet as you would expect, lest it disturb the VIPs in its cabin. In our testing, we recorded a zero-to-60-mph time of just 4.5 seconds—impressive for a large SUV that weighs as much as the Cullinan does. An electrified powertrain is rumored to join the lineup later, but for now Rolls-Royce’s V-12 engine is the sole offering. All-wheel drive is standard, although we suspect buyers will never venture off the tarmac. The Cullinan rides on an air suspension that automatically adjusts its height using a road-scanning camera; ride comfort is beyond the standards of regular luxury vehicles, and it wafts down the road transmitting nothing unpleasant to the interior.
