Page will succeed Tobias Sühlmann, who will leave the Volkswagen Group subsidiary to lead design at UK sport car maker McLaren Automotive.
Page, 51, will be responsible for defining Bentley's design language as it transforms into an electric-only brand by 2030, Bentley said in a release.
Under Page, Volvo began a similar transition, debuting the EX90 full-electric flagship SUV last November, which followed the electric-only C40 compact crossover and the battery-driven version of the XC40 compact SUV. The next model with Page's fingerprints on it will be the EX30 small SUV that Volvo will debut June 7.
Volvo, however, announced in January that Jeremy Offer, 55, would become the brand's new global head of design, succeeding Page, who would be demoted to the role of senior advisor. That meant he would report to Offer.
Offer joined Volvo from EV startup Arrival, where he served as senior vice president and chief design officer.
Those changes took affect May 1.
Prior to the transition, Volvo CEO Jim Rowan told Automotive News Europe that Offer, who has no experience at a traditional automaker, was picked because of his deep knowledge of industrial design.
"Quite frankly, we have so many people in our business who really understand automotive design, people with decades and decades of experience. What we want to bring in now is more of that industrial design," he said.
Second stint at Bentley
For Page, who will start September 1 and report to Bentley CEO Adrian Hallmark, this is his second stint at the British brand. He was Bentley's head of interior design from 2001 until 2013.
