The quad-turbo is dead.
Or at least, its production line is. Bugatti has rolled the final W16 Mistral out of its Molsheim factory, marking the end of a twenty-year run for that massive 8.0-liter engine. The Chiron lineage is capped. The roadster has hit its apex.
But here is the catch. You already know this.
If you have enough money to shake trees, the engine doesn’t have to die. Last year, Bugatti quietly opened “Programme Solitaire.” It is a bespoke channel for the ultra-wealthy. Want a custom one-off? Buy it. Want few-off builds? Go ahead. You can still commission new cars using the retired W16 powertrain. They already built two—the Brouillard and the FKP Veyron Hommage. Both pulled from Molsheim’s leftover stock of engines and chassis.
“We all know there’s a loophole.”
But the Mistral matters differently.
For collectors, there is a distinction between a factory-cataloged hypercar and a bespoke commission. The Mistral was the last of the former. It was a homologated model. Limited to 99 units. Finished. When this specific unit rolls off the line, the chapter closes. Everything else is just an epilogue. A bespoke afterthought.
The last Mistral is striking. Not in a flashy way.
It wears a two-tone livery mixing Pearl and Sparkle shades. The open two-seat cabin uses Magnolia and Grey Carbon Matt leather, thanks to the Bugatti Sur Mesur personalization team. But the details are where the ego lives.
The traditional dancing elephant badge? Gone. In its place sits a bespoke aluminum falcon head atop the gear selector. A nod to the Middle Eastern heritage of the buyer. That same falcon appears as a hand-embroidered stretch of Anthracite across the doors. Then there is the armrest. A frozen crystal glass sculpture, made by Lalique.
How do you justify spending €16 million on a car? You add art.
Ettore Bugatti’s own signature is stamped on the engine cover. Stitched into the headrests. Etched into the aluminum door sills. Inside the cockpit, a plate bears the car’s silhouette alongside the phrase “The last of its kind.” It sits among other wild Sur Mesur creations like the dragonfly-themed “Fly Bug,” the porcelain-white “Blanc Éterne,” or the “Caroline” bought by a father for a daughter.
There is also the “World Record Car.” It hit 282 mph with Andy Wallace behind the wheel in Papenburg. Now it sits in private collection. Believed to be worth €14 million. More than triple the starting price.
Underneath, the engineering remains brutal. The final 8.0-liter W116 produces 1,500 hp and 1,60 Nm of torque. Same specs as the track-only Bolide, just dressed up.
It feels final.
Yet, knowing Bugatti, it probably isn’t. The door is technically locked, but they keep the key. And for the right price? They might just build another one.
Who are we to say no?
