Rimac Technology, a leading Tier 1 automotive supplier, has engineered and integrated the complete hybrid system for the Bugatti Tourbillon hypercar—setting a new benchmark in electric and hybrid propulsion for ultra-high-performance vehicles.
The newly unveiled Bugatti Tourbillon features an advanced 800V hybrid architecture, combining Rimac’s latest electric drivetrain technology with a naturally aspirated 8.3-liter V16 engine. The result is an unmatched blend of raw mechanical power and instant electric torque, offering an extraordinary driving experience.
At the core of the Tourbillon’s innovation is Rimac’s electric powertrain: three high-performance motors—two at the front axle and one at the rear—producing a combined 800 hp and spinning up to 24,000 rpm. This setup is paired with a compact, 25 kWh oil-cooled battery pack designed in a T-shape for both energy storage and structural integration. The system enables more than 60 km of electric-only range and supports seamless torque fill to the V16’s delivery.
Despite the complexity of the hybrid setup, the Tourbillon is both shorter and lighter than its predecessor, the Chiron, thanks to Rimac’s advanced packaging and efficiency innovations. Notably, the complete rear powertrain assembly—including engine, eight-speed dual-clutch transmission, and rear motor—weighs just 430 kg, matching the Chiron’s engine alone.
Rimac’s proprietary Silicon Carbide inverters, fifth-generation Battery Management System (BMS), and trio of electronic control units play critical roles in ensuring efficiency, safety, and high performance. Designed to ASIL D and ASPICE Level 2 standards, the components maintain peak functionality even at the Tourbillon’s top speed of 445 km/h.
Mate Rimac, CEO of Bugatti Rimac and Founder of Rimac Group, emphasized the project’s significance:
The Tourbillon perfectly showcases Rimac Technology’s full-system integration capabilities. Despite its complexity, the system delivers greater performance with less weight—proving our relentless push for engineering excellence.
Nurdin Pitarević, COO of Rimac Technology, highlighted the company’s broader ambitions:
While the Tourbillon is a technical showcase, we’re equally focused on scaling our solutions. We apply the same engineering precision to high-volume clients like Porsche, BMW, and CEER Motors, helping them bridge into the electrified future.
Alongside propulsion systems, Rimac also developed Tourbillon’s domain control units and integrated thermal management systems, ensuring optimal operation of the battery and motors under extreme conditions.
Only 250 units of the Bugatti Tourbillon will be produced, with customer deliveries beginning in 2026.
