We already knew that Bentley is building only 18 examples of its $2 million Batur W-12-powered grand touring coupe by Mulliner. And now, the UK-based automaker has introduced its ability to 3D print solid gold for the coupe's cabin trim. Available to the lucky few buyers as an option (and why wouldn't they?), this is the first time Bentley has applied this "ground-breaking process" in the automotive industry.

This brilliant new technique allows those buyers to have up to 7.408 ounces (210 grams) of 18-karat gold, which is most visible on the Charisma Dial that encircles the start/stop button and is used to switch driving modes. Bentley says the dial's design complements that of the Batur's front grille. That 3D-printed gold can also be applied to the brand's iconic Organ Stop vent controls located on the dashboard. There's also a gold insert marker available on the steering wheel.

The Mulliner customization division worked with Cooksongold, a centuries-old goldsmith firm based in Birmingham, England, to craft the Batur's gold trim. Bentley claims all of the gold used here is 100% sourced from old jewelry, as opposed to mining once again. The recycled gold is then ground into a fine powder prior to beginning the 3D-printing process.

This recycling technique, Bentley adds, "reflects [its] commitment to a more sustainable future and is in line with the company's Beyond 100 strategy, to be end-to-end carbon neutral by 2030." Prior to being 3D-printed, each gold part is digitally designed using CAD models. Laser melting printers are then used prior to the 3D printing itself.

Upon completion, each component is hand-finished and polished. As for the Batur itself, well, it's quite something. Each one comes powered by the legendary twin-turbocharged 6.0-liter W12 that required over 100 weeks for development. Total output comes to 730 horsepower and 738 lb-ft of torque. According to Bentley, it's the most powerful application to date of this engine.

The Batur also comes equipped with an air suspension, four-wheel steering, and active anti-roll bars. Before any customization takes place, pricing begins at $2.02 million a pop. Deliveries are set to get underway in the middle of next year.
