The Mulsanne’s two available variants are mostly similar in terms of performance and finishing options like paint and leather. The base model shares its 506-hp twin-turbo V8 with the Extended Wheelbase model. The base model can be had with five seats as standard while the EW can only be had with four seats. Front and rear seat heating, ventilation, and massage functions are available for both, as are refrigerated bottles coolers for champagne or more hard liquor, along with matching flutes or tumblers. The EW model adds 9.8 inches of legroom over the regular model and has larger rear windows and also offers extended leg rests for more horizontal reclining comfort in the rear. Either model can also be had with dual 10.4-inch tablet displays that are presented via an electric motor in the front seats. Both models feature WiFi connectivity and Apple CarPlay.
