The Bentayga Extended Wheelbase Mulliner marks a new peak for Bentley, elevating the Bentayga lineup and the overall Bentley models. Bentley says this model enhances the existing blend of powerful supercar performance, all-terrain capability, dynamic driving, and limousine-like rear cabin found in the Bentayga EWB.
The flagship Bentley Bentayga EWB Mulliner surpasses competitors in cabin space and its unique enhancements transform each journey into a cherished experience. Whether you’re seated at the wheel or in the spacious rear cabin, this SUV represents the pinnacle of luxury in the SUV category.
When one spends over a million ringgit on a car, it can be taken for granted that it will be of the highest quality with the best materials. If it is a sports model, then it would be expected to deliver truly high performance. And where comfort is concerned, that’s a given – with emphasis on the rear accommodation taking precedence over the front (unless it’s a convertible which would usually be driven by the owner).
Bentley’s Azure range, introduced in May last year, goes beyond the realms of just being comfortable. With this range – available for all Bentley models – the wellbeing of the occupants is paramount and not only is there superlative comfort along the way but the occupants can also arrive at their destination in an even better shape, more relaxed than when they left home or office.
In the 1960s, Volvo drew attention to the importance of a car seat being designed for a correct posture to provide not just comfort but also promote driving safety. Its seat designers consulted specialists on a subjected that would come to be known as ‘ergonomics’ and developed a revolutionary seat that would set new standards in the industry.
The carmaker’s pioneering work encouraged other companies to also give more attention to car seats and not treat them as just a place for the occupants to sit on. In the years to follow, many more new ideas (some by Volvo) would be introduced in seat design which would increase comfort as well as safety.
New benchmark in wellbeing
In 2022, the new Airline Seat Specification of the Bentley Bentayga EWB represents ‘the most advanced seat ever fitted to a car’. It demonstrates a new benchmark in wellbeing features, providing the most comfortable experience possible for those travelling on extraordinary journeys. 50% of the customers who are buying the longer version of the Bentayga have specified this seat to go with their purchase.
Along with the systems to deliver Auto Climate and Postural Adjustment, the Airline Seat has a suite of technology beneath its handcrafted leather surfaces. An array of no less than 12 electric motors operate silently to deliver 22 ways of adjustment in the seat alone. This allows the user to shape the seat to suit their body shape and also to work or rest. The motors are joined by three intelligent pneumatic valve electronic control units, and the combination of motors and valves is overseen by a master Seat Motion & Wellbeing ECU.
Studies have shown that actively supporting body weight in a dynamic way relieves strain, which can prime mental stress and create lack of focus. Natural supported postures have been shown to alleviate stress from tensed muscles. The postural adjustment system automatically makes micro adjustments to the passenger’s seating position and pressure points, using an algorithm developed in collaboration with a chiropractor.
The system can apply 177 individual pressure changes across 6 fully independent pressure zones over a 3-hour period, improving comfort and minimizing fatigue throughout a journey. By subtly changing the shape of the surfaces of the seat over time, no single area of the body endures pressure fatigue for an extended period – meaning the occupant is always comfortable.
Postural Adjustment System
While many fatigue recovery system exist (seat massage, for example), the Postural Adjustment system is the next step further providing a proactive anti-fatigue system. By subtly adjusting the contact pressure between body and seat through soft pneumatic activation zones, the system goes beyond the 2D motions typical of adjustable seats, and employs a 3-dimensional twist to relieve pressure points. These motions are controlled by complex algorithms that have been developed in collaboration with a chiropractor who deals with clients who experience discomfort on long car journeys.
Working with specialists Comfort Motion Global (CMG), Bentley has developed a scientific, pneumatic postural adjustment system. CMG has been working in the field of fatigue prevention for several years, conducting medical-based research trials that highlight the benefits of changes in posture for comfort and wellbeing.
By creating subtle changes in the seat surface contact zones, body tissues that have been under pressure are relieved, and other areas, pressure is then applied. This allows the body a chance to locally recover naturally. The postural motion creates small changes in back and limb angles and can increase blood flow. Particularly in the lower back and lower limbs reducing discomfort, therefore passengers remain more alert and focused for a much longer period.
Seat surface sensing system
Many premium and luxury models have ventilated seats nowadays, with fans within that blow hot or cool air onto the body. The Airline Seat offers even more with the world’s first seat surface sensing system for thermal comfort. It uses a suite of sensors that constantly measure both passenger contact surface temperature and humidity level, to an incredible accuracy of 0.1°C every 25 milliseconds.
The passenger defines an optimal surface temperature target from 7 settings. Sensors measure and produce live data to determine what seat heating, cooling and ventilation levels are required to achieve the best comfort temperature for the passenger. The system then maintains the optimal thermal comfort throughout the journey with micro adjustments to the seat thermal system to maintain the setpoint.
In trials, it was observed that a human can only notice a change in surface temperature between 1° -2°C, but the system is constantly monitoring actual temperature to a much more detailed level, so it knows what the passenger is going to need before they would know themselves. This live data allows the system to activate before the passenger even knows it is required, providing an intelligent and autonomous experience where manual control is no longer needed to maintain comfort.
Auto Climate System
The auto climate system, which has 7 set points) uses existing seat heating technologies, but a new seat ventilation fan has been developed that can move approximately 80% more air than the previous system. Less power is consumed than the current seat climate system and, in Auto Climate mode, the overall power consumption of the complete system is around 40% less than being manually activated by the passenger.
The EWB Airline Seats have optimized seat contact profiles as well as a complex seat interlayer construction, tuned to work in perfect harmony with the chassis of the car. Working together the ride comfort is smooth and passengers are isolated from road vibration.
The adjustable profiles can morph to suit different customer shape and build. The adjustable leg and footrest feature allows customers to achieve a seated posture that is individually comfortable to them for longer periods.
The Airline Seat Specification also adds further cushion and backrest bolster adjustment, cushion extension, electric headrest height adjustment and a deployable footrest to the back of the front passenger seat. The rear seat passenger on this side of the car can also move the front passenger seat forwards via a ‘VIP mode’.
Rather than develop another new and bigger SUV model, Bentley has instead extended the wheelbase of the Bentayga to create a new luxury flagship. And it’s not been a cost-saving project either as the company reveals that it made a ‘9-figure investment’ for the development of the new model which has over 2,500 new parts and a complete new underfloor.
The new Bentayga Extended Wheelbase (or EWB) promises ‘the best rear cabin experience’ which should be acceptable to those who have been used to the Mulsanne limousine (now discontinued). Since its unveiling in 2015, the Bentayga has been a major success for the brand, ascending to become its bestseller. In 2021, the Bentayga accounted for just over a third of the 14,659 vehicles sold by Bentley and the EWB is eventually expected to make up 45% of all Bentayga sales. No doubt, many will be in China where long wheelbase models are highly favoured.

Increased length all for rear cabin
The current Bentayga is the second generation of the model and for the EWB, the wheelbase has been extended by 180 mm – from 2995 mm to 3175 mm to stretch the overall length to 5322 mm (in comparison, the BMW X7 is 5151 mm).
The increased length is all given to the rear section, creating a cabin space that is said to be larger than any other luxury competitor. The Bentayga EWB also provides an extra 10 mm of headroom compared to a Mulsanne, whilst having a roofline 100 mm lower than competitors providing a sporting and well-proportioned silhouette.
While it is recognisable as a Bentayga, there are 4 exterior differences that identify the EWB: the longer profile, a new front grille, a new polished 22-inch 10-spoke wheel, and a repositioned sunroof. Taking inspiration from the new grille on the Flying Spur, the Bentayga EWB has a ‘Vertical Vane Grille’ design that is visually striking. The unique grille consists of bright chrome vertical vanes sitting in front of a black mesh grille.
The repositioned panoramic sunroof illustrates the focus on the rear cabin ambience. It has been moved rearwards by 125 mm, providing the optimum position to bathe the rear cabin seating area in natural light. The sunroof can be controlled via the rear cabin Touch Screen Remote, as well as by the front cabin console.
Attention to wellness
‘Wellness’ seems to be a new trend in the development of cabin environments and to provide this at the highest level, there is the Bentley Airline Seat specification. This is the most advanced seat ever fitted to a car, with 22-ways of adjustment and postural adjustment technology.
The postural adjustment system automatically makes micro adjustments to the occupant’s seating position and pressure points, by measuring pressure across the seat surface. The system can apply 177 individual pressure changes across 6 fully independent pressure zones over a three-hour period improving comfort and minimising fatigue throughout a journey.
World-first climate control
Equally impressive is the new auto climate sensing system (a world-first) which senses occupant temperature and surface humidity and then determines whether to apply heat, ventilation or both simultaneously to keep the occupant at optimum thermal wellbeing. A comfortable thermal environment can also alleviate fatigue, reduce irritability, and this can help to improve driving safety as well.
Even without the advanced system the ventilation and air conditioning system in the rear cabin has been enhanced to further improve onboard wellness. The rear ventilation activates only when rear occupants are detected, reducing rear cabin fan noise. A separate air ionisation system that improves air quality with lower airborne particulates is dedicated to the rear section.
Superlative craftsmanship throughout
As with every Bentley, superlative craftsmanship is a given and the Bentayga EWB incorporates a more advanced stitching design created using digital craftsmanship. Diamonds can be seen elongating symmetrically from the centre of the seatbacks shoulder panels and along the length of the door, reflecting the extension in the car itself.
The new interior style of the longer rear doors also includes a unique design showcasing the optional ‘Metal Overlay in Veneer’. Using a thin metal strip just 0.07 mm thick, an intricate design is bonded by hand on the surface of the veneer before the part is lacquered and polished.
New features include Bentley Diamond Illumination (where light is emitted through small perforations in the soft feel door trim) which demonstrate how technology combines with contemporary craftsmanship to deliver incredibly modern design in luxurious materials. With 24 billion trim combinations alone (and a total number of possible specifications running into the trillions), the cabin of the Bentayga EWB is capable of offering the most individual Bentayga ever.
For the first time on a Bentley, power closing doors can be specified. Also fitted as standard are new ‘waterfall illumination’ interior lamps providing subtle illumination to the rear cabin. The illumination is focused towards the centre of car, and improves the passenger’s visibility of the key central controls and features.
Electronic All Wheel Steering
The Bentayga has been praised for its dynamic abilities, with impressive its performance on the road and in ride and handling. This is expected to also apply to the Bentayga EWB which has Electronic All Wheel Steering and Bentley Dynamic Ride as standard.
Though it will certainly be heavier than the other Bentayga models, the EWB should have equally muscular performance with the proven 4-litre, 32-valve dual twin-scroll turbocharged petrol engine. Mated to an 8-speed automatic gearbox, this 550 ps/770 Nm V8 can propel the Bentayga EWB to 100 km/h in a claimed 4.6 seconds and a top speed of 290 km/h.
Production of the Bentayga starts during the fourth quarter of this year, with deliveries to the first customers taking place before the end of the year.
