The 2022 BMW X7 is the largest and most luxurious SUV ever offered by the Bavarian automaker, but some buyers would like their family vehicle to feel a bit more special. Last year, BMW showed off the X7 Dark Shadow Edition, which was limited to only 600 units worldwide (75 of which came to the United States). BMW has just showed off a new X7 variant called the Nishijin Edition that's even rarer. In fact, only three will ever exist, and the car will only be sold in Japan.

Unlike the Dark Shadow, which was finished in a stealthy matte grey, the Nishijin X7 is finished in a bold BMW Individual color called Ametrine (purple). BMW says this hue uses "multiple pigments to achieve deep colors through multi-layer coating," and the color changes drastically depending on the light. It's gorgeous.

A rare special edition with an outrageous exterior wouldn't be complete without a cabin to match. Luckily, BMW hasn't given the Nishijin Edition a dull black interior; it's significantly more interesting. The base interior is a BMW Individual full leather merino option finished in ivory white color. Unfortunately, the Nishijin-ori roof liner seen here in the pictures will not be included on the production models, but customers will get special trim pieces made using foil-drawing technology.

This unique trim was created by applying foil to Japanese paper. The surface is then painted with gold-silver foil in a process called "five-color gold layering." This step is repeated five times to create a three-dimensional sensation and deeper colors.

The X7 Nishijin Edition is based on an xDrive40d Pure Excellence model. This means it is powered by a 3.0-liter turbocharged diesel engine equipped with 48V mild hybrid technology, producing 340 horsepower and 516 lb-ft of torque. Pricing starts at 16,800,000 yen, or around $153,000 by today's exchange rates. We won't get the Nishijin Edition here in the US, but perhaps we could get an American version with some denim trim?
