The V16 Era Begins: Bugatti's Tourbillon Redraws the Hypercar Map

Two years after its unveiling, the Bugatti Tourbillon remains the most ambitious engineering statement in the hypercar class. It does not simply replace the Chiron. It retires the W16, the engine that defined Bugatti's modern era, and commits the brand to something no rival has attempted: a naturally aspirated V16 with hybrid assistance, developed in the Rimac era, hand-built in Molsheim.

It retires the W16, the engine that defined Bugatti's modern era, and commits the brand to something no rival has attempted: a naturally aspirated V16 with hybrid assistance.

The engine: sixteen cylinders, no turbos

The heart of the Tourbillon is an all-new 8.3-litre V16, developed by Bugatti Rimac with assistance from Cosworth. It produces 1,000 PS (986 hp) at 9,000 rpm entirely without forced induction, with 900 Nm of torque. The block uses a cross-plane crank, dry-sump lubrication, 64 valves and a 14.5:1 compression ratio. It is nearly a metre long and weighs 252 kg, roughly half the mass of the Chiron's W16, according to Bugatti's own materials.

Cosworth's managing director of powertrains, Bruce Wood, described it as the most powerful naturally aspirated engine Cosworth has ever built (CarBuzz). That is a telling superlative from a company that built Formula One engines and the Gordon Murray T.50's V12. The intake plenum went through countless design iterations, and the engine is deliberately presented as a visible centrepiece rather than hidden under covers.

The hybrid system: Rimac's hand

Electric assistance comes from three motors: two on the front e-axle with full torque vectoring and one mounted between the engine and the transmission. Together they contribute 800 PS, bringing total system output to 1,800 PS (1,775 hp). The battery is a 25 kWh oil-cooled 800V pack, T-shaped and housed in the central tunnel as a structural element of the monocoque, developed by Rimac Technology with more than 1,500 cells, silicon-carbide inverters and motors spinning to 24,000 rpm. Electric-only range exceeds 60 km on the WLTP cycle, and the car is a plug-in hybrid.

An all-new 8-speed dual-clutch transmission, designed from scratch for the car and mounted longitudinally behind the engine, drives all four wheels. Bugatti quotes 0-100 km/h in 2.0 seconds, 0-200 km/h in under 5.0 seconds, 0-300 km/h in under 10.0 seconds and 0-400 km/h in under 25.0 seconds. Top speed is 380 km/h as standard, rising to 445 km/h with the Speed Key fitted. Notably, Bugatti has published no official weight figure, saying only that the Tourbillon weighs less than the Chiron despite the hybrid system.

Production status: late 2026, still waiting

Bugatti's stated plan has always been for production and customer deliveries to begin in 2026, once W16 Mistral production closed out. As of late September 2026, however, no customer delivery has been publicly documented. Outlets reporting in September 2026 describe deliveries as scheduled to begin late in the year, with no confirmed first handover and no true resale market yet formed. Prototype VP1 was photographed winter testing in Croatia over the 2025-26 winter, and development work, including the Rimac-developed hybrid powertrain, was confirmed through 2025.

Commercially, the car is done: all 250 build slots are sold at a price from €3.8 million before taxes, with production scheduled through 2029.

Why it matters

The Tourbillon is significant for what it refuses to do. At a moment when much of the industry treats electrification as a path to simplicity, Bugatti chose mechanical maximalism: the largest, most complex naturally aspirated engine in any current production car, paired with an 800V hybrid system. The Équipe Pur Sang option package, unveiled in March 2025 with an eight-pipe exhaust, new aerodynamics and a deployable rear wing, shows how owners are already personalising the platform.

The car also sets up the brand's next chapter. Coachbuilt one-offs through Programme Solitaire, including the F.K.P. Hommage shown at Rétromobile in January 2026 and the Bolide-based Destrier, draw on the same engineering culture. And Bugatti has hinted that at least one Tourbillon version could surpass 500 km/h. On paper, this is the most interesting powertrain in the industry. The proof of production will come with the first customer cars, expected before the year is out.
