The Bugatti Brouillard has debuted as the first one-off hypercar from the French marque's new Solitaire coach-building programme.

Solitaire is inspired by Bugatti's coach-building days from the early 20th century, where buyers could commission unique bodies on existing platforms.

The Brouillard is built on the same W16 platform as the Chiron and Mistral, but nearly every body panel is bespoke and hand-crafted.

Brouillard's fascia features a sculpted bumper, slatted LED headlights, and massive air intakes.

Bugatti's hallmark horseshoe grille is retained on the Brouillard, and features a central spine that extends throughout the body.

The side profile shows off a C-shaped intake behind the window line, lots of carbonfibre trim, and huge forged wheels.

An integrated ducktail wing adds downforce while maintaining the Brouillard's flowing shape.

X-shaped LED tail-lamps are a nod to the W16 Mistral, with a Chiron-inspired diffuser below.

Inside, the Brouillard is kitted out in custom tartan fabric, green-tinted carbon fibre, and machined aluminium.

The Brouillard's steering wheel gets a unique tartan centre marker and hand-finished controls.

A horse sculpture is engraved in the Brouillard's crystal gear shifter, honouring Ettore Bugatti's beloved steed.

The Brouillard is powered by Bugatti's 1,600hp, 8.0-litre, quad-turbo W16 engine.

Bugatti will showcase the Brouillard at Monterey Car Week.
