Bentley’s headline claim for the Bentayga is that it’s “the fastest, most powerful, most luxurious and most exclusive SUV in the world”.
Ten months ago, we reported that there was just enough permeability to an almost watertight fulfilment of that brief to justify denying the W12 a half-star’s worth of recognition.
On paper, the Diesel comes to market with almost 30 percent less power than the W12 and priced at £25k less – facts that don’t immediately promise it will satisfy at least 50 percent of the Bentayga’s mission statement any better than its rangemate.
But a delve into this car’s particulars reveals some of the ways in which it might upstage its petrol counterpart.
Torque is the first of them. The 3956cc ‘triple-charged’ V8 in the Bentayga Diesel produces precisely the same 664lb ft as the 5950cc twin-turbo W12 in the regular Bentayga. But while the W12 needs 1350rpm on the tacho to make it, the V8 diesel has it on tap from just 1000rpm, or, as near as makes almost no difference, from idle.
That should make it stronger and more flexible on in-gear acceleration than the already flexible W12 and could be an even bigger boon for towing, crawling and other things that big SUVs are commonly asked to do.
