Promotion: Bentley's bespoke commissioning division, Mulliner, has unveiled its flagship SUV that aims to combine the performance of a supercar with the comfort of a limousine.

Designed to offer the "ultimate in comfort and space", the Bentayga Mulliner builds on the brand's focus on prestige, presence and personalisation.

The car aims to provide high levels of comfort while giving drivers full off-roading capabilities as well as supercar performance from its 4.0-litre, twin-turbocharged V8 engine.

"The launch of the Bentayga Extended Wheelbase Mulliner defines a new pinnacle for the Bentayga family and indeed the Bentley model range, adding a new level of modern craftsmanship to the already potent combination of supercar performance, go-anywhere ability, driving dynamics and limousine rear cabin of the Bentayga EWB," said Bentley.

Combined with the car's driving and handling performance – it can go from zero to 60 miles per hour in 4.5 seconds and has a top speed of 180 miles per hour – its extended wheelbase creates more internal cabin space than its luxury competitors.

Within the car, Mulliner has added a range of new design features and bespoke enhancements designed to "make every journey an occasion to be savoured".

The cabin interior is defined by a streamlined, high-gloss veneer, quilted upholstery, which envelops the seats and doors, and a diamond-milled, aluminium finish across the centre console.

These luxury finishes are complemented with high-tech additions including illuminated 3D treadplates and LED welcome lamps, which project visuals onto the floor.

The highly customisable interior can be fitted with either four or five seats that each benefit from Bentley's latest postural technology, which offers 22 ways of adjusting the seats to support the comfort and wellbeing of passengers.

The Bentley Airline Seats were informed directly by the experience of high-end flying. In Relax Mode, they can recline to nearly 40 degrees, while Business Mode moves the seat to an upright position that's more suitable for working.

In line with the brand's ethos, the interiors are personalisable with nearly 4,000 colour combinations. Buyers can choose from a selection of eight curated tri-tone colour combinations such as the warm-toned Flare or cool-toned Storm, or specify their own palette using any three colours.

These hues are designed to complement the soft, olive tan leather lines of the car's cabin. The leather is tanned using organic by-products from the olive oil industry, a technique that requires less water than the conventional tanning process. This keeps the leather free of harmful metals, minerals and aldehydes and seeks to encourage a healthier interior environment for users.

All the interior materials were carefully considered, with the cabin's thick, deep pile overmats made from a specially selected wool variety, chosen for its cleanliness and purity of colour, while the cabin carpet is made from 100 per cent recycled nylon.

With roots that can be traced back to 1760, before the birth of the motor car, Mulliner has worked with Bentley since 1923 creating everything from special features and finishes to entirely new coachbuilt vehicles.

The Bentayga Mulliner stands alongside the Flying Spur Mulliner, Continental GT Mulliner, and Continental GTC Mulliner – each the flagship of their respective model lineups.
