Rimac Technology has presented new EV battery platforms, ultra-compact powertrains, and next-generation control electronics at IAA Mobility, detailing platforms developed through collaborations with ProLogium, Mitsubishi Chemical Group and Kautex Textron. These solutions are designed for large-scale production and production-ready, according to Rimac, aiming for integration in hundreds of thousands of vehicles in the near future.

Rimac’s next-generation battery system, developed with ProLogium and Mitsubishi Chemical Group, integrates solid-state cell technology and new housing solutions. Rimac notes that ProLogium’s solid-state cells paired with Mitsubishi Chemical Group’s advanced materials result in a system that is lighter, more energy-dense, and safer than previous generations. For near-term EV applications, Rimac is highlighting an “Evo Technology” battery based on 46XX Gen2 nickel manganese cobalt (NMC) cells within a thermoplastic composite housing, co-developed with Kautex Textron, featuring optimized thermal management.

Rimac has designed a platform supporting both high-energy and high-power configurations using either 46XX or 2170 cell formats, with scalable, cell-to-pack architecture and integrated safety and thermal features.

Rimac’s powertrain platforms include the SINTEG 300 and 550 single electric motor eAxles, which can reach over 8 kW/kg power density and more than 90 Nm/kg torque density. The patented rotor achieves speeds up to 25,000 rpm, with both coaxial and offset layouts offering output from 150 to 360 kW and torque between 2,500 and 6,250 Nm. These are targeted at a range of EV applications, from sports coupes to SUVs. Rimac is also preparing its high-torque “XXL Axle”—a dual-motor unit validated at over 11,000 Nm—to enter production in 2026 with a global automaker, offering more than 95 percent peak efficiency.

In the field of electronics, Rimac also displayed a portfolio of domain and zonal electronic control units (ECUs) powered by NXP’s S32E2 processors. These units consolidate multiple traditional ECUs into high-performance domain controllers, managing tasks such as torque vectoring, battery management, and high-voltage distribution. The architecture is designed around centralized software-defined vehicle principles, supporting real-time operation, over-the-air updates and advanced safety requirements.

All newly unveiled technologies will be produced at Rimac’s Croatian manufacturing facilities, which consist of over 95,000 square meters of space across two sites, including its flagship campus.

“What we’re showcasing at IAA represents the convergence of breakthrough innovation and production readiness. 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,” said Nurdin Pitarević, COO, Rimac Technology.
