A standard Mulsanne is not something to be trifled with, but this looks like it would pick you off before you even had the chance to get in its way.

Bamford X is the suitably sinister name for this murdered-out Bentley Mulsanne Speed. It’s the latest one-off creation by Mulliner, Bentley’s in-house bespoke department, built for watch customizer and JCB earthmover heir George Bamford.

The bespoke timepieces made by the Bamford Watch Department are known for their signature black-on-black colour scheme, which is reflected in the Mulsanne. Its bodywork is finished in mile-deep Beluga black that mimics the colour Bamford achieves through its Military Grade Titanium Coating and Graphite Particle Coating processes.

The finishing touch is a one-off portable watch holder made from carbon fibre.

All the exterior trim that would usually be finished in polished stainless steel has been through a Physical Vapor Deposition treatment that turns it into shimmering black “Darkware." All of the interior brightwork has been swapped out for Darkware, as well.

Unique, 21-inch wheels, based on the Mulliner Driving Specification items and finished in black, and a dark, dark window tint finish off the decidedly menacing look of the Bamford X.

Not that a standard Mulsanne Speed is something to be trifled with. It is a truly gargantuan thing, measuring 5,575 millimetres (219.5 inches) from bow to stern, 1,926 mm (75.8 in) across the beam, and 1,521 mm (59.9 in) from top to bottom. And thanks to a monstrous, 6.75-litre, twin-turbo V8 motor that churns out 537 horsepower and 811 pound-feet of torque, it thunders from 0-100 kilometres per hour (0-62 miles per hour) in just 4.9 seconds, and runs on to a top speed of 305 km/h (190 mph).

See one charge up behind you on the highway with headlights blazing and you will get out of the way. The Bamford X, though, looks like it would pick you off with a rifle before you even had the chance to get in its way.

The exterior theme continues inside, which black upholstery and trim. Mulliner took the almost unprecedented decision of allowing Bamford to spec the seats with alcantara centre panels - the only other Bentley customer allowed that concession is the British Royal Family. The leather piping, stitching, and storage compartment liners are finished in bright blue, another Bamford signature.

The finishing touch is a one-off portable watch holder made from carbon fibre.

“This is personalization. This is how you do personalization,” Bamford said.
