1,600-hp Bugatti Mistral roadster marks the end of the line for the W16 engine

Bugatti's mighty W16 engine will retire in the coming years, but it's not sailing off into the sunset quietly. It will power one final street-legal car: a roadster named Mistral that stands proud as the first convertible of the Chiron era. Built due to customer demand, the Bugatti Mistral is a striking, limited-edition model that looks ready to add another speed record to the French firm's trophy case. I sat down with some of the people who created it, including Bugatti design director Achim Anscheidt and head of design Frank Heyl, to get the droptop's full story. "For the final road-going appearance of Bugatti’s legendary W16 engine, we knew we had to create a roadster. Well over 40% of all Bugatti vehicles ever created have been open-top in design," said Bugatti-Rimac CEO Mate Rimac. Heyl added that customers "begged" Bugatti to create a Chiron-derived convertible, and that granting them this wish was a "bucket-list" item for the members of his team. Power for the Mistral comes from the same 8.0-liter, quad-turbocharged 16-cylinder engine that propelled the Chiron Super Sport 300+ to a record-breaking 304.773 mph in 2019. It's rated at 1,600 horsepower, and it spins the four wheels via a seven-speed dual-clutch automatic transmission. Bugatti estimates that the Mistral's top speed will check in at approximately 261 mph (420 kph). Will this number get verified? Hell, yes! "There can only be one goal in mind: to become the fastest roadster in the world once more," Bugatti pledged in a statement. While the Mistral is Chiron-based, Bugatti made several important structural changes to offset the inevitable loss of structural rigidity caused by chopping off the roof. Heyl explained that the monocoque's sills and transmission tunnel were reinforced and that the a- and b-pillar structures are new, though the front crash structure is the same. And, the two models intentionally share no exterior styling cues. "We had the pressure of creating something that is precious and valuable in a car collector's garage. It's not just a fashion statement: 'Oh, let's do a roadster!' Or, even worse, 'Let's take a Chiron and just cut it open,' which would have looked terrible. This burdens us with the responsibility that this is the last of its kind of that generation and how that's going to sit in those collections," Anscheidt told Autoblog.

Completed Bugatti Type 64 Coupe to make debut at Quail Motorsports Gathering

If you're one of the Autoblog faithful you might remember our story on the Bugatti Type 64 Coupe chassis on display at the Mullin Automotive Museum, one of just three built by the French carmaker before the death of Jean Bugatti. At the time, we told you the museum had plans to finalize the construction of the car with custom coachwork - only one example received bodywork from the factory - and now that time has finally come to unveil the finished product. Today it was announced that a "virtually completed" car will make its debut later this month at the Quail Motorsports Gathering in Monterey.
"We've dedicated much of our efforts at the Museum to honor the Bugatti family and the marque, but never have we done something of this scale," said Peter Mullin, Chairman of the Mullin Automotive Museum. "I cannot imagine a greater token of respect to the Bugatti family than to help finish Jean Bugatti's beloved final masterpiece."
We'll have live photos of the completed Bugatti Type 64 Coupe as part of our extensive Monterey coverage next week. Want to see the car in person for yourself? The museum says it will have also have the car on display at their facility in Oxnard, CA later this year.
