As for the newly formed One of One division, it's a bespoke customization program akin to Rolls-Royce Bespoke, Bentley Mulliner, or Lamborghini Ad Personam. Genesis claims it combines customer aspirations with "Genesis designers' passions to create special cars" and that each vehicle is hyper-personalized to the customer's needs, describing the product that will hail from the division as "a one-of-a-kind work of art."

Every detail can be customized, from the exterior finishes and detailing to the embroidery and decor garnishing of the interior. The paint finishes are said to be of a higher standard than normal Genesis products, with "endless finish options," including the brushed one on the GV80, pinstripes, and two-tone aesthetics all available.

Every decor element, every piece of upholstery, and every surface can be customized, as is the case with the very first Genesis One of One creation, the extended-wheelbase Genesis G90.
