A Bentley, most any Bentley, would be more than enough for most of us. But there are always some customers who want something even more exclusive. And according to the latest, the British automaker is only too glad to oblige.

Autocar reports that Bentley's Mulliner division is preparing to launch what's being described as the "ultimate open-cockpit sports tourer," and it stands to be the most exclusive and expensive set of wheels ever to wear the vaunted Flying B badge. Something along the lines of the McLaren Elva, only softer, pricier, and even rarer.

The as-yet-unnamed project is anticipated to draw heavily on the dramatic EXP 100 GT concept (pictured above), but ditch the roof. And we don't mean in favor of a folding mechanism, either. Like the aforementioned McLaren, it'd reportedly have no roof whatsoever, consigning it to be driven only on sunny days. But oriented as it would be towards touring – in the grandest of style – it'd most assuredly have a windshield (which is something the Elva will offer only as an option). And it could employ some very exotic materials, like the copper-infused wood from a 5,000-year-old tree used in the concept.

Motivation is expected to come from (a version of) the 6.0-liter twin-turbo W12 used in the Continental GT, Flying Spur, and Bentayga. But because it'd be lighter than any of those, it'd likely be even faster.

Word has it that the Mulliner customization and coachbuilding division – which produced the Mulsanne-based Grand Convertible, the Mulsanne Grand Limousine, and Queen Elizabeth II's State Limousine – would make only ten or twelve of them, and would charge "upwards of £1.5 million" (or about $2 million) for each of those examples made to their commissioning customers' personal specifications. Not for the riff-raff, in other words, which means most of us.
