Bugatti W16 Mistral Blanc Éternel: Porcelain on Wheels

(Motorsport-Total.com/Motor1) – Bugatti has presented a one-off vehicle based on the W16 Mistral roadster in collaboration with the Royal Porcelain Manufactory Berlin (KPM). The model, produced under the customization program “Bugatti Sur Mesure,” is named “Blanc Éternel” and marks the end of the brand’s W16 engine era.

The cooperation builds on an earlier project from 2011, in which both companies designed the Veyron Grand Sport “L’Or Blanc.” While the design of that model was inspired by the flowing brushstrokes of a porcelain vase and the light reflections on the body, the visual concept of the “Blanc Éternel” (eternal white) is based on the geometry of modern automotive design.

Digital design and handcrafted execution

The W16 Mistral was entirely designed in the digital space without the use of physical clay models. The sculptural exterior shell is mathematically based on a network of precisely controlled surfaces called Non-Uniform Rational B-Splines (NURBS). This normally invisible construction layout (“patch layout”) serves as the primary design element of the exterior on the “Blanc Éternel.” Fine black lines run across the pure white primed body, visibly tracing the underlying digital grid of the vehicle geometry.

Despite the purely digital creation of the pattern, the physical implementation on the vehicle was done by hand by artisans. After applying the white primer and subsequently sanding the surfaces, the contours were manually masked directly on the real vehicle using adhesive tapes.

After removing the defined stripes, the exposed areas were painted black to create the contrasting, sharp-edged graphic pattern. This interplay of lines emphasizes the functional body features of the roadster, including the newly shaped horseshoe grille, the C-line on the flank, and the X-shaped structure of the rear lights.

Integration of functional porcelain elements

The vehicle features special applications made of genuine KPM porcelain both on the exterior and interior. On the outside, among other things, the EB emblem, the fuel and oil caps, as well as two inlays with the manufactory’s scepter logo on the engine cover, were made from the ceramic material.

The production of these components requires precise mathematical pre-calculation, as porcelain shrinks by exactly 17 percent during the firing process in the kiln. This dimensional change must already be taken into account during the modeling phase to ensure the fit at the vehicle’s mounting points.

The black-and-white line design continues in the cockpit. The digital surface pattern was applied directly onto the white leather upholstery using a specially developed painting and masking process with black paint. Additionally, various control elements and contact surfaces inside the cabin were made from porcelain to enable direct tactile interaction. These include the speaker covers, inlays on the knee pads in the footwell, the casing of the shift accelerator, an inlay on the center console, and the window control buttons.

Alongside the vehicle presentation, KPM Berlin and Bugatti are launching a limited porcelain collection of 1,000 handcrafted pieces. This includes two different cup variants, designed to reflect the vehicle’s design.
