With a claimed top speed of 187 mph, Bentley boasts that the Bentayga is the fastest SUV in the world. The claim is made possible by a twin-turbo 6.0-liter W-12 that makes a mighty 600 hp and 664 lb-ft of torque; an eight-speed automatic drives all four wheels. The interior can be configured to seat four or five; only the finest leather will cosset those lucky posteriors. Diesel and hybrid powertrains will be offered in the future; the Bentayga goes on sale in early 2016.
