The extended wheelbase is just what the Bentley Bentayga needed to help it compete with the Rolls-Royce Cullinan, which is arguably the king of ultra-luxury SUVs. Just a small increase to the overall length of the Banytaga results in massive gains for rear-seat passengers. What Bentley fails to mention, though, is that you also have to sacrifice some trunk space to stretch your legs. As such, there is simply no room to slot in extra seats, so five people is as many as this model will carry. The Airline Seat Specification can be optioned to give the two outboard rear seats 22 directions of adjustability, heating and ventilation, and massage functions.
