With an estimated top speed of 187 mph, Bentley boasts that the Bentayga will be the fastest SUV in the world; it also shows that Bentley means business. The claim is made possible by a twin-turbo W-12 that makes a mighty 600 hp; 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.
