The Bugatti Tourbillon, the latest masterpiece from Bugatti, is breaking new ground not just with its V16 hybrid powertrain or its 3D-printed suspension components, but with a surprising innovation in its sound system. In a departure from traditional audio setups, the Tourbillon does not use conventional speakers at all. Instead, it transforms the very structure of the car into a sound-producing body. At the heart of this innovation are piezoelectric transducers that vibrate the carbon-fiber monocoque itself, turning the car’s chassis into a giant speaker.
This radical approach was showcased during a recent visit by Top Gear magazine to Bugatti Rimac’s new headquarters in Croatia. CEO Mate Rimac, known for his passion for engineering precision, was eager to demonstrate the new system. In the Tourbillon, the piezo elements are placed at strategic points across the carbon-fiber tub.
One such component, acting as a subwoofer, is mounted on the roof of the car. Unlike traditional speakers, which rely on heavy magnets and diaphragms to create sound, piezoelectric transducers use quartz crystals to generate vibrations. These vibrations are transferred directly into the carbon-fiber structure, which acts as a resonant body to produce sound throughout the cabin.
Rimac explained the thinking behind the design, pointing out its efficiency in weight, space, and performance. “Believe me, the sound quality of that car is in a different universe compared to a Chiron,” he said. His confidence lies in the fact that not only does this system reduce the overall mass of the vehicle, but it also offers an immersive audio experience by distributing sound through the entire structure rather than isolated points.
The Tourbillon’s sound system stands in stark contrast to that of its predecessor, the Bugatti Chiron. In the Chiron, Bugatti partnered with Accuton to develop one of the most opulent audio systems ever fitted in a car. It featured four one-carat diamond tweeters, designed to deliver unparalleled precision in high-frequency sound reproduction. These diamond membranes could transmit audio frequencies up to 100 kilohertz, far beyond the range of human hearing. While the Chiron aimed for luxury through extravagance, the Tourbillon prioritizes innovation and weight savings.
Ultimately, the Tourbillon’s speakerless sound system is a striking example of how Bugatti is rethinking performance in every corner of the car. By making the carbon-fiber chassis part of the audio architecture, the Tourbillon turns a functional component into a sensory experience, offering a bold vision of the future of automotive design.
