Rimac Technology Powers the Bugatti Tourbillon with Cutting-Edge Battery and Powertrain Tech
Rimac Technology, a Tier 1 technology supplier to the automotive industry, engineered, designed and seamlessly integrated the cutting-edge battery system, e-axles and electronic control units for the Bugatti Tourbillon hyper sports cars. The Tourbillon represents the culmination of Rimac Technology’s expertise in developing advanced electric powertrains, battery systems, and electronic control units. Working in close collaboration with Bugatti Rimac’s engineering teams, Rimac Technology designed a sophisticated 800V hybrid system that seamlessly integrates with the Tourbillon’s naturally aspirated 8.3-liter V16 engine, delivering an incomparable driving experience – the raw emotive power of a large capacity naturally aspirated engine with the instant power of electric motors. At the heart of this technological masterpiece lies Rimac Technology’s advanced electric powertrain, featuring three high-performance electric motors – two mounted at the front axle and one at the rear. These motors collectively produce 800 horsepower and can spin up to 24,000 rpm, powering an e-axle that boasts one of the highest power densities in the industry. The electric powertrain also features Rimac’s Silicon Carbide inverter technology with accompanying proprietary software ensuring not only high performance but also exceptional efficiency and operational safety. Despite its three motors, battery pack and V16 engine the Tourbillon is both shorter and lighter than its predecessor, which was solely powered by a quad-turbo W16 engine.
The entire hybrid system is powered by Rimac Technology’s state-of-the-art 25 kWh battery pack, featuring an innovative T-shaped design that serves as both an energy storage system and a structural component of the vehicle. This 800V battery system incorporates Rimac’s advanced oil-cooling technology and over 1,500 individual cells immersed in oil, managed by the company’s fifth-generation Battery Management System (BMS). The BMS, developed in accordance with ASPICE Level 2 standards and supporting the highest automotive safety standard (ASIL D), ensures optimal performance, longevity, and safety throughout the battery’s lifecycle.
