- Bugatti has revealed a one-off W16 Mistral Blanc Eternel through its Sur Mesure programme.
- The roadster revives Bugatti's porcelain collaboration with KPM Berlin, 15 years after L'Or Blanc.
- Its image set shows exterior, interior and workshop details from the unique commission.
Bugatti has given the W16 Mistral a very literal art-car send-off, revealing a one-of-one Blanc Eternel commission that blends hypercar theatre with porcelain craftsmanship.
A porcelain callback

Bugatti presents the car as a Sur Mesure creation developed with Konigliche Porzellan-Manufaktur Berlin, better known as KPM.
It links the new roadster back to L'Or Blanc, the porcelain-inspired Veyron Grand Sport created with the same Berlin porcelain house 15 years ago.

Rather than simply repeating that earlier blue-and-white theme, Bugatti says the Blanc Eternel design reflects the way the W16 Mistral was developed digitally.
Fine black lines run over the white bodywork to trace the car's underlying digital surface layout, making the usually invisible design geometry part of the finished look.
Hand-painted digital lines

The handwork is still very real.
According to Bugatti, the body was finished in pure white, then carefully taped by hand so the black linework could be painted directly onto the physical car.
The result highlights the Mistral's horseshoe grille, rising C-line, large air intakes and X-shaped tail-light architecture.
Porcelain you can touch

KPM porcelain is used for more than show. Bugatti says the EB emblem, fuel and oil caps, engine-cover inlays, speaker cover plate, kneepad inlays, gear-shifter shells, centre-console armrest inlay and window-lifter buttons are made from the material. The company also notes that porcelain changes size during firing, with the final dimensions differing 17 per cent from the unfired component, so the parts had to be engineered with that shrinkage in mind.
Bugatti has not disclosed any mechanical changes for the Blanc Eternel. The focus is instead on the W16 Mistral as the final roadgoing expression of the brand's W16 engine era, wrapped in a bespoke design that turns the car itself into the canvas.
