The actual engine that propelled Bugatti into modern history and the realm of record-setting supercars has come to an end. On Thursday, Bugatti revealed that the last W16 Mistral has departed from the factory, signaling the conclusion of production for the distinctive engine that has powered every Bugatti since the brand’s resurgence by the Volkswagen Group at the turn of the century.
Similar to that revival, the quad-turbocharged 8.0-liter W16 was conceived by former VW Group CEO Ferdinand Piëch, who also championed the group’s acquisitions of Bentley and Lamborghini. As per the official narrative, even prior to the decision to resurrect Bugatti, Piëch fantasized about a colossal engine, sketching a naturally aspirated 18-cylinder monster made from three VW VR6 blocks while on a Shinkansen high-speed train traversing Japan.
Convincing Piëch to change his mind was no easy feat, but thankfully, someone intervened. After VW obtained the rights to the Bugatti name (following a failed revival attempt that resulted in the EB110 and the canceled EB112 sedan), the aim was to fit the horse-collar grille onto a vehicle boasting 1,000 metric horsepower. The intricate W18 would have had a displacement of 6.2 liters and produced merely 547 hp, leading to a swap for the forced-induction W16 design, which was first trialed in 2001.
This engine propelled the Veyron to production-car speed records in both the original 16.4 variant (253 mph) and later the Super Sport version (267 mph). An extensively revised version powered the Chiron to its own array of records, including a top speed of 304 mph for the specially crafted Super Sport 300+ model that shattered the 300-mph threshold for production vehicles.
Bugatti initially had no plans for a Chiron roadster, but the automaker never turns down a chance for a high-priced, limited-edition model. Therefore, to give the W16 a proper farewell, it initiated an accelerated development program for the Mistral. The $5 million roadster made its debut at 2022 Monterey Car Week, and in 2024, it set a new record for open-top vehicles (282 mph), driven by a 1,578-hp variant of the legendary W16. The first of the 99 customer vehicles was delivered in 2025. The final of those cars features a subtle two-tone livery of Pearl and Sparkle paint, with a “the last of its kind” script throughout, and a dashboard plaque denoting it as the ultimate W16-powered Bugatti.
The transition from one era to another is rarely this straightforward. Just days prior to the completion of the last Mistral, Bugatti held a ribbon-cutting event for La Manufacture, the facility that will produce its forthcoming supercar. The Bugatti Tourbillon still boasts 16 cylinders, but they are now configured in a more traditional “V” orientation rather than the “W” layout that was previously a VW Group trademark at the encouragement of CEO Mate Rimac.
**The End of the W16 Engine Era for Modern Bugatti**
The Bugatti name, renowned for luxury and high-performance vehicles, has long been celebrated for its engineering excellence and groundbreaking designs. At the core of this legacy is the W16 engine, an extraordinary powertrain that has characterized Bugatti’s contemporary history. However, as the automotive sector pivots towards electrification and sustainability, Bugatti’s storyline with the W16 engine nears its conclusion.
**The Genesis of the W16 Engine**
Unveiled in 2005 alongside the Bugatti Veyron, the W16 engine represented an extraordinary milestone in automotive engineering. This 8.0-liter quad-turbocharged engine, consisting of 16 cylinders in a unique W arrangement, generated an impressive 1,001 horsepower in its original form, later boosted to 1,600 horsepower in the Chiron Super Sport 300+. The W16’s architecture permitted compactness while delivering remarkable power, allowing Bugatti models to reach extraordinary speeds and performance benchmarks.
**An Emblem of Performance and Luxury**
The W16 engine has powered some of the most iconic hypercars ever made, such as the Veyron, Chiron, and Divo. These vehicles not only established speed records but also redefined luxury through their stunning craftsmanship and advanced technology. The synthesis of rapid acceleration, state-of-the-art aerodynamics, and exquisite interiors has positioned Bugatti as a leader in the hypercar arena.
**Environmental Factors and Industry Evolution**
As the global automotive environment shifts, the emphasis on sustainability and lower emissions has grown critical. Both governments and consumers are increasingly supporting greener technologies, prompting manufacturers to reevaluate their powertrains. Bugatti, acknowledging this transformation, has declared that the W16 engine will be retired in favor of hybrid and electric solutions. This change aligns with the broader industry movement, as numerous luxury automakers investigate electrification to comply with regulatory requirements and consumer demands.
**The Concluding Chapter: The Last of the W16**
Bugatti’s ultimate production models featuring the W16 engine, like the special-edition Bolide and the final versions of the Chiron, are destined to become highly sought-after collectibles. These vehicles not only symbolize the height of internal combustion performance but also stand as a tribute to Bugatti’s engineering heritage. The conclusion of the W16 era signifies a noteworthy moment in automotive history, as fans and collectors prepare to say goodbye to a powertrain that has captured the imaginations of many.
**Looking Forward: Bugatti’s Next Steps**
As Bugatti transitions into a new phase, the brand is set to push the envelope further with hybrid and electric technologies. The upcoming models are anticipated to integrate Bugatti’s performance legacy with contemporary sustainability practices, ensuring that the brand maintains its leadership in the automotive field. Although the W16 engine will be missed, Bugatti’s dedication to quality and performance will surely persist in new formats.
**Final Thoughts**
The legacy of Bugatti’s W16 engine is one of remarkable accomplishment and innovation. As the automotive world embraces a new age of electrification, Bugatti’s choice to retire the W16 signifies the end of an extraordinary chapter. Nevertheless, the essence of performance and luxury that the W16 exemplified will continue to shape Bugatti’s future projects, guaranteeing that the brand remains an icon of automotive excellence for years ahead.
