Source: BugattiSource: BugattiTalk about an engine being truly iconic: Bugatti's W16 set the world alight when it debuted in the Veyron in 2004, and its grasp on the ultra-exotic market has hardly loosened since. Yet after a surprisingly long run, the quad-turbo, 8.0-liter monster's time is finally up, marked by one last Mistral to celebrate the W16's time on this planet.Source: BugattiSource: BugattiThe last Bugatti Mistral is here, and it's an important car for the company for more reasons than just being the end of the model's run. Mistral number 99 bears the final application of the W16 engine-making a massive 1,578 horsepower and 1,180 lb-ft of torque-and also stands as the final car Bugatti is building while a subset of the Volkswagen Group.AdvertisementAdvertisementBugatti's celebration of the Mistral (and the Chiron on which it's based) comes with a special name, too: "The Last of Its Kind." This name might sound like a "special" model Jeep under its Twelve4Twelve release program, but it really does denote the close of a chapter in the Bugatti book.Source: BugattiSource: BugattiThe last Mistral-custom-ordered, as all Mistrals have been-is draped in "Pearl" and "Sparkle" paint, which seems appropriate for a car that would be happy sipping champagne in Monaco. It also has Magnolia and Grey Carbon Matt interior accents, plus a bunch of touches harkening back to Bugatti's past.Source: BugattiSource: BugattiAdvertisementAdvertisementBugatti says this final Mistral is "the swansong to this masterpiece of powertrain engineering," and that last hurrah also comes with holding the record for the world's fastest open-top car. Back in 2024, Chief Test Driver ("Pilote Officiel" in Bugatti speak) Andy Wallace ran the one-of-one W16 Mistral World Record Car to 453.91 km/h (282 mph), solidifying the model and engine in the history books.With all 99 Mistral models accounted for, the W16's time in production is finally complete. The next Bugatti will arrive with a "traditional" V16 under the Tourbillon name, and 250 units will be made. Of course, extremely well-off prospective buyers will still be able to buy a W16-powered car under the Programme Solitaire-just don't call it "production."
