Rimac Technology has revealed its latest portfolio of advanced electric vehicle technologies at IAA Mobility 2025 in Munich. The presentation includes next-generation solid-state battery solutions, evolved battery platforms, and innovative e-Axles. These advancements are designed to reinforce Rimac Technology’s position as a leading Tier 1 supplier supporting the global automotive industry’s transition to electrification.
Key Highlights
- Debut of groundbreaking solid-state battery technology developed for enhanced energy density and safety.
- Introduction of the ultra-compact SINTEG 300 & 550 eAxles, which set new industry benchmarks for power and torque density.
- Showcase of a centralized electronic architecture using advanced domain and zonal ECUs.
- Confirmation that the unveiled technologies are production-ready solutions intended for high-volume manufacturing for global OEMs.
Advanced Battery Platforms
Rimac Technology introduced three distinct battery platforms engineered for various applications.
The Next-Gen Technology platform is an advanced system featuring solid-state cell technology. Developed in collaboration with ProLogium and Mitsubishi Chemical Group, this platform integrates cutting-edge solid-state cells with innovative housing solutions. The result is a battery that is lighter, safer, and more energy-dense, pushing the boundaries of current EV battery capabilities.
The Evo Technology platform represents the immediate future of high-performance battery systems. It is based on 46XX Gen2 NMC cells and features a next-generation thermoplastic composite battery housing co-developed with Kautex Textron. This solution combines proven cell chemistry with advanced packaging and thermal management.
The Hybrid Technology platform is designed to address key market demands for both high-energy and power-dense hybrid packs. It offers dimensional scalability and interchangeable cell configurations using both 46XX and 2170 cell formats within a cell-to-pack architecture.
Next-Generation Powertrain Systems
The company also unveiled a new range of powertrain solutions. The SINTEG 300 & 550 are ultra-compact, fully integrated eAxles that achieve unprecedented performance levels. With a power density exceeding 8 kW/kg and torque density surpassing 90 Nm/kg, they set new industry benchmarks. These eAxles, based on Rimac Technology’s Scalable Powertrain Platform, are configurable and target performance vehicles across all segments.
Additionally, the High Torque XXL Axle was showcased, with a production version set to enter series manufacturing in 2026 for a global OEM. This powerful dual-motor eAxle has a validated peak efficiency of over 95% and delivers more than 11,000 Nm of axle torque.
Centralized Electronics and Controls
Rimac Technology presented its state-of-the-art portfolio of domain and zonal ECUs, powered by NXP’s S32E2 real-time processors. This centralized architecture consolidates multiple traditional ECUs into single high-performance domain controllers. This approach dramatically simplifies vehicle complexity, reduces cost and weight, and enables OEMs to fully embrace the era of software-defined vehicles. These next-generation ECUs manage critical functions from torque vectoring to battery systems while ensuring safety and supporting over-the-air (OTA) updates.
Production and Manufacturing Readiness
All technologies unveiled at IAA Mobility will be produced at Rimac’s advanced facilities in Croatia, which span more than 95,000 m² of production space. The flagship Rimac Campus represents an investment of over €200 million in manufacturing capabilities, providing the scale to support multiple high-volume projects simultaneously.
“What we’re showcasing at IAA represents the convergence of breakthrough innovation and production readiness,” said Nurdin Pitarević, COO of Rimac Technology. “These aren’t simply concept technologies; they’ve been developed to be production-ready solutions that will power hundreds of thousands of vehicles in the coming years.”
As a Tier 1 technology supplier owned by the Rimac Group, Rimac Technology specializes in electrification technologies, including battery systems, e-axles, and electronic systems for global automotive OEMs.
