One of 99: 2025 Bugatti W16 Mistral Heads to Broad Arrow's Quail Auction as the World's Fastest RoadsterBroad Arrow Auctions has consigned one of the most consequential Bugattis to reach the block in years for The Quail Auction 2026, set for Friday, August 14, in Carmel, California: a 2025 Bugatti W16 Mistral, one of only 99 examples built to close out the marque's monumental 8.0-liter, quad-turbocharged W16 engine. Cataloged with a pre-sale estimate of $8,000,000 to $10,000,000, this particular Mistral wears a Matt Argent and Black Carbon exterior over a Beluga Black and Tangerine cabin, shows just 652 miles, and comes complete with its full Bugatti Owner's Metal Chest.The Mistral marks the final chapter for Bugatti's 8.0-liter, sixteen-cylinder engine, an unmistakable powerplant that first debuted in the Veyron back in 2005 and went on to define hypercar performance for nearly two decades. Rather than let the W16 simply fade away, Bugatti chose to send it off with an open-top variant built on Chiron underpinnings but wrapped in entirely bespoke carbon fiber bodywork. The result is both a eulogy and a victory lap: a roofless hypercar that instantly became the fastest production roadster in the world.Design duties fell to Bugatti's Frank Heyl alongside predecessor Achim Anscheidt and exterior designer Florian Westermann, who drew inspiration from the pre-war Type 57 Roadster Grand Raid while folding in visual cues from the Centodieci, Divo, and La Voiture Noire. Nearly every panel does double duty as an aerodynamic or cooling element: a reworked horseshoe grille isolates radiator airflow, new intakes beside the headlights and wheel arches feed the intercoolers, and the X-shaped taillights double as heat exhausts. Even the interior carries a story, with a milled aluminum shift knob housing a tiny amber-encased dancing elephant, a nod to Rembrandt Bugatti's sculpture that once graced the Type 41 Royale.AdvertisementAdvertisementUnderneath, the Mistral carries over the Chiron Super Sport 300+'s quad-turbo specification, good for 1,578 horsepower and 1,180 lb-ft of torque routed through a seven-speed dual-clutch transmission and all-wheel drive. Bugatti quotes a zero-to-62 mph sprint of just 2.4 seconds and a top speed of 260 mph, though the car has proven capable of far more. In November 2024, a specially prepared customer example reached 282 mph during testing in Papenburg, Germany, reinforcing the Mistral's status as the quickest open-top production car ever built.This particular example carries roughly $650,000 in personalization over its factory sticker price, according to the listing. It was first titled as a corporate vehicle in October 2025 before the consigning owner acquired it the following spring and based it in Beverly Hills, California, where it recently received a service and inspection from Bugatti's local dealer, including a fluid top-up and a preemptive belt and tensioner replacement. With just 652 miles on the odometer and its full delivery kit intact, it presents as close to new as a Mistral is likely to get on the open market. Enthusiasts curious how the Mistral's record-setting pace stacks up against decades of speed-focused machinery may want to check out the Petersen Automotive Museum's world's fastest production cars exhibit, which traces the same obsession with outright velocity that defines this Bugatti.Placing a number on a car like this is tricky business, since Bugatti's most extreme creations rarely trade often enough to build a deep sales history. Hagerty's valuation tools are a useful starting point for tracking how the broader Chiron and Veyron family has moved over time, even though a limited-run halo car like the Mistral will always command its own conversation among the handful of collectors who can consider one. For a sense of how strong appetite remains for one-of-a-kind hypercars right now, look no further than Jay Kay's custom LaFerrari, which recently sold for nearly $6 million at auction in Monaco.The Quail Auction 2026 lands on Friday, August 14, in the middle of Monterey Car Week, giving Broad Arrow a marquee stage to sell one of the ultimate send-offs in Bugatti history.
