Bentley customers will be delighted to hear that production of the Bentayga Extended Wheelbase has just kicked off at the company’s facility in Crewe, UK and that deliveries are now underway.

With production of the Bentayga EWB now underway, the British car manufacturer has announced full performance specifications for the luxury SUV.

Slotted beneath the hood of the Bentayga EWB is a 4.0-liter twin-turbocharged V8 petrol engine that is good for 542 hp and 568 lb-ft (770 Nm) of torque. This engine propels the SUV to 60 mph (96 km/h) in 4.5 seconds and through to a 180 mph (290 km/h) top speed.

Of course, the Bentayga EWB is focused on much more than performance. Indeed, by extending the wheelbase by 180 mm (7 inches) through changes to the underfloor, side panels, and roof, Bentley has been able to dramatically increase interior space in the second row. Those ordering the SUV can do so in four- and five-seat versions, alongside a 4 + 1 layout that has two sculpted rear seats with a small jump seat between them for taking a third passenger in the rear for short journeys.

Those seeking the ultimate in luxury can order the Bentayga EWB will the optional Airline Seat Specification that reclines the rear seats to 40 degrees and adds Seat Auto Climate, Postural Adjustment, additional cushion and backrest bolster adjustment, heated rear doors, and center armrests.

Like all Bentley models, customers are offered a dizzying array of options and ways to personalize their Bentayga EWB. In fact, there are some 24 billion trim combinations available.

Bentley says that since the unveiling of the EWB, 40 per cent of Bentayga customers have been opting for it.

“The new Bentayga Extended Wheelbase is the next chapter in the Bentagya story which, since the original luxury SUV came to market in 2015, has transformed the sector and resulted in record sales,” member of the board for manufacturing at Bentley Motors, Peter Bosch, said. “At Bentley, we collaborated with our customers to stretch the class-leading SUV’s breadth of ability even further, leading to a rear-cabin experience comparable to the legendary Mulsanne.”
