At this year’s Frankfurt Auto Show, back in September, Bentley’s lead engineer Peter Guest confirmed to Automotive News that the marque was already testing prototype versions of a diesel Bentayga.

At present, Bentley has not given a timetable for the introduction of this diesel version, nor is it known whether the recent admissions of deceit in US by the Volkswagen Group, which owns Audi and Bentley, might affect any future launches.

Billed as the ‘fastest, most powerful, most luxurious and most exclusive SUV in the world’, it has a W12 powertrain and dynamic styling that still nevertheless marks it out as a Bentley. Inside, all is luxury and a state-of-the-art infotainment system is the icing on a very considerable cake. It’s so good, in fact, that The Queen ordered the first one! We’ll bring you more news on the Bentayga’s diesel version as soon as it emerges.
