The largest engine ever used in a European car lives inside the Bugatti Tourbillon

In true Bugatti fashion, the story behind it is even more interesting.
Did you know the largest engine ever installed in a European production car is not a turbocharged monster from the early 2000s… but a brand-new engine developed in the electrified era? And it sits at the heart of the extraordinary Bugatti Tourbillon.
In a time when most manufacturers are downsizing engines, adding turbochargers or abandoning combustion entirely, Bugatti has done something completely unexpected.
A modern V16 born from racing DNA
The Tourbillon’s engine was developed in collaboration with Cosworth, a legendary name in motorsport engineering. The result is a powerplant that feels almost surreal in today’s automotive landscape.
The 8.3-liter V16 stretches nearly a meter in length and revs to 9,000 rpm, delivering more than 1,000 horsepower from the combustion engine alone. But unlike the turbocharged engines that defined Bugatti’s previous generation, this one is naturally aspirated.
That choice was deliberate. Without turbochargers muffling the experience, the engine produces what Bugatti describes as “mechanical music”, a sound reminiscent of classic endurance and Formula racing engines from the 1960s.
Yet the construction is entirely modern. Titanium internals, advanced materials and precision engineering make the V16 lighter and more responsive than its predecessor.
From W16 legend to V16 revolution
For nearly two decades, Bugatti’s reputation was built on one engine: the iconic Bugatti W16. Introduced in the Bugatti Veyron in 2005, the quad-turbo W16 shattered expectations with 1,001 horsepower and pushed production car engineering into unexplored territory.
Later, the Bugatti Chiron elevated the concept even further, exceeding 1,500 horsepower. But as emissions regulations tightened and technology evolved, Bugatti needed a new approach. The Tourbillon’s V16 represents that shift.
A hybrid powertrain producing more than 1,800 horsepower
While the V16 itself already produces more than 1,000 horsepower, the Tourbillon’s full powertrain goes significantly further. Three electric motors (one at the front axle and two at the rear) work alongside the combustion engine to deliver a combined system output of over 1,800 horsepower.
This architecture provides instant torque, advanced torque vectoring and seamless all-wheel drive performance. The result is staggering performance:
0–100 km/h in around 2 seconds
Top speed between 380 and 445 km/h depending on configuration
But perhaps more importantly, the hybrid system allows the car to operate with a level of efficiency and precision that would have been impossible with combustion alone.
AutoNext Take: A bridge between two automotive eras
Manufacturers are balancing electrification, regulation and heritage, often struggling to preserve emotional driving experiences while adapting to new technologies. The Bugatti Tourbillon may be one of the most fascinating answers to that challenge.
In an age dominated by silent electric motors and shrinking displacement, Bugatti chose to build the largest engine ever seen in a European road car and pair it with cutting-edge electric technology.
