There are bespoke commissions, and then there are obsessions made real. The Bugatti W16 Mistral ‘Fly Bug’, unveiled from the Atelier in Molsheim on 30 April 2026, is firmly the latter. It is the fourth chapter of a collector’s deeply personal anthology, and arguably the most technically ambitious one yet.
The Machine Beneath the Art
Before discussing what makes this specific car remarkable, the Mistral itself demands proper introduction. Bugatti built exactly 99 examples of the W16 Mistral, each priced at €5 million net, and the entire production run sold out before a single car reached a customer. The name draws from the powerful, cold wind that sweeps through southern France’s Rhône valley, and the car earns it.
At the heart of the Mistral sits Bugatti‘s legendary 8.0-litre quad-turbocharged W16 engine, producing 1,600 PS (1,578 bhp) and 1,600 Nm of torque from as low as 2,000 rpm. That power feeds through a 7-speed dual-clutch DSG transmission to a permanent all-wheel drive system, launching the car from 0–100 km/h in 2.4 seconds. In November 2024, Bugatti validated the Mistral’s ambitions with an official top-speed run of 453.91 km/h (282 mph), making it the fastest open-top production car ever built. The W16 engine layout places two VR8 banks side by side, sharing a common crankshaft, compressing what should occupy a full metre of engine bay into just 710 mm. It is genuinely one of the great feats of modern automotive engineering.
The Mistral also marks the absolute end of the W16 road car era. With Bugatti‘s future heading into hybrid territory, this engine will never power another production road car. The ‘Fly Bug’ is therefore not simply a bespoke Mistral; it is a personalised farewell to one of the greatest powertrains ever conceived.
What Is Bugatti Sur Mesure?
Bugatti formalised its Sur Mesure programme in December 2021, translating the French phrase ‘tailored’ into a full department dedicated to bespoke commissions. The programme builds on the marque’s historical coachbuilding roots and draws together the expertise of Bugatti’s Color, Materials, and Finish (CMF) team based at the Berlin Design Studio. Graphic designers, material specialists, visualisers, and modellers all collaborate with the client to transform a personal vision into a production reality. The process runs from initial design concept through to vehicle production and final handover, with dedicated one-to-one support from the Sur Mesure team throughout.
The programme now underpins some of the most extraordinary Bugatti creations of the modern era, from the Type 55-inspired Chiron Super Sport to the pearl-detailed W16 Mistral ‘La Perle Rare’. Each project redefines what is technically possible with production materials and paint systems.
A Collector’s Four-Car Vision
The ‘Fly Bug’ did not arrive in isolation. It joins three earlier commissions from the same collector, each drawing inspiration from small creatures of the natural world. The Veyron Grand Sport Vitesse ‘Hellbug’ launched the series; the Chiron ‘Hellbee’ followed with a graphic interpretation of its insect theme; and the Divo ‘Lady Bug’ introduced an intricate geometric diamond pattern composed of around 1,600 precisely arranged shapes flowing across its bodywork. For the Mistral, the creative team chose the dragonfly: a creature of iridescent wings, effortless speed, and quiet elegance that aligns naturally with the Bugatti character.
The initial brief emerged from a conversation between the collector and Frank Heyl, Bugatti’s Head of Design. From there, the CMF team took over and developed the visual language that would unite all four cars whilst giving the Mistral its own distinct identity.
‘Dragonfly Blue’ and the Ellipse
The exterior finish, named ‘Dragonfly Blue’, shifts between blue and turquoise depending on light conditions and viewing angle, directly replicating the shimmering quality of a dragonfly’s wing membrane. Applying this colour consistently across the body and the wheel rims required the paint team to bridge the technical gap between two entirely different materials and paint systems, a challenge that consumed considerable development time.
Layered over that colour sits the signature ellipse pattern, growing denser towards the rear of the car and fading into the darkness of the air intakes. This gradient creates a sense of motion even when the car stands still, as if the dragonfly is caught mid-flight.
Three Technical Firsts
The ‘Fly Bug’ pushed Bugatti‘s craftspeople into genuinely new territory on three fronts. First, the team integrated the iconic Bugatti Macaron, the oval emblem present on Bugatti horseshoe grilles for over a century, directly into the painted ellipse graphic on the car’s flank. This had never been done before. Reproducing every fine detail, including the ring of dots and the precise lettering, at the correct scale and position within a flowing graphic required painstaking trial and development.
Second, the interior application broke new ground. An exclusive multi-layered material, leather laid over Alcantara in a geometric pattern and colour-matched to ‘Dragonfly Blue’, was applied across both the door panel face and the armrest area simultaneously. Bugatti had never wrapped a graphic pattern continuously across both surfaces before, and the engineering team had to work closely with the CMF team to ensure the material sat perfectly across the curved geometry without any distortion.
Third, the gear selector houses Rembrandt Bugatti’s famous ‘Dancing Elephant’, a nod to the sculptor whose animal bronzes form an enduring part of the family heritage and a personal acknowledgement of this collector’s love of the natural world.
“A bespoke colour developed from scratch, a Macaron integrated into a painted graphic for the first time in our history, and an interior material application we had never attempted before.”‘
— Frank Heyl, Head of Design at Bugatti
That is a concise summary of why projects like this matter. They do not simply personalise a hypercar; they expand what a hypercar can be.
