Powered by the same 447kW and 900Nm 6.0-litre twin-turbo W12 as the 'regular' Bentayga, the Mulliner takes an even more luxurious approach to the interior and finishings of the large SUV.
On the outside, the Mulliner features two-tone paintwork and specific 22-inch 'Paragon' wheels. The craftsmanship and attention to detail are second to none, with the wheels each taking nine hours to individually mill from a solid block of aluminium.
To further stand out from the crowd, the 'B' logo on the center caps floats upright (like on a Rolls Royce Phantom) at speeds of up to 270km/h.
Inside, the bespoke nature of the Mulliner Bentayga is more evident, with the front seats trimmed in a different material to the rear, a tone of dark to light transitioning throughout the car.
Even the piano-black trim of the front cabin fades to burr walnut in the rear.
The Mulliner specification sees the four-seat comfort specification applied (where all seats offer electric adjustment, heating, ventilation and massage), and are separated with a console which includes a wine chilling cabinet, and crafted Cumbria Crystal champagne flutes.
Passengers are treated to the 20-speaker 1950-watt Naim audio system, as well as a raft of driver assistance features the position the Mulliner Bentayga at the very peak of the specification tree.
You can even tweak the LED puddle lamps to display a personal message, logo or type.
Pricing for the Mulliner Bentayga starts from $633,200, and the model will be produced to order, in limited numbers.
The Bentayga is the first vehicle to receive the Mulliner treatment as a production model, but Bentley has committed to a Mulliner specification of every new model, to arrive approximately one year after the initial release.
