Ever since Rolls-Royce entered the SUV segment two years ago with the Cullinan, tuning companies have launched all kinds of aftermarket parts for it.

Some of them are quite discreet, whereas others are definitely OTT. Wald International’s ‘Black Bison’ leans towards the second category and is officially up for grabs in the US.

The lower grille has been given a makeover to match the upper part, and the front bumper sports a new apron with chrome trim. More shiny inserts can be seen on the side skirts and at the back, alongside a more aggressive two-part diffuser, LED brake light, and tailgate-mounted spoiler.

The 10.5×24-inch forged wheels, made specifically for the Cullinan by Wald, are also part of the revisions, alongside the lowering hardware kit that makes it look more like a very expensive super wagon than an SUV.

You won’t find any upgrades under the hood from the Japanese tuner, where the twin turbocharged V12 remains totally stock. With 6.75 liters in displacement, this engine pumps out 563 HP (571 PS / 420 kW) and 627 lb-ft (850 Nm), with the peak torque being available from 1,600 rpm.

Despite the luxury amenities, complemented by the magic carpet-like ride and cocooned cockpit, not to mention the 5,864-pound (2,660-kg) curb weight, the Cullinan is quite fast. It will sprint to 60 mph (96 km/h) from a standstill in 5+ seconds and reach a top speed of 155 mph (250 km/h).
