First comes the 682-hp Cadillac Escalade V, which makes some of the most deafeningly beautiful noise from its supercharged 6.2-liter V-8. The Rolls-Royce Cullinan makes almost no noise as its twin-turbocharged, 6.75-liter BMW V-12 catapults it in outrageous comfort down the track. The brand new Range Rover LWB P530 also uses a BMW engine — the latest version of the 15-year-old 4.4-liter N63. Then, the 5.2-liter, supercharged Raptor R goes on to race the outrageous Lamborghini Urus and Mercedes-AMG G63. This is a race to watch — to see if any of these heavyweights can dethrone the Porsche Cayenne Turbo GT, the quickest SUV or truck we've ever tested.
