At the recent IAA Mobility 2025, Croatian technology company Rimac Technology showcased a range of production-ready solutions designed to power the future of electric vehicles. The technologies, which include next-generation solid-state battery technology, domain and zonal ECUs, and high-performance e-Axles, are intended to power hundreds of thousands of vehicles in the coming years.
Rimac Technology's next-generation solid-state battery technology was developed in collaboration with ProLogium and Mitsubishi Chemical Group. The innovative battery system features innovative housing solutions and is lighter, safer, and more energy-dense. The new battery system promises to deliver all-new levels of performance, with power density exceeding 8 kW/kg and torque density surpassing 90 Nm/kg.
The industrialization line for the high torque XXL Axle will be located at one of Rimac Technology's production facilities on the outskirts of Zagreb, Croatia. The high torque XXL Axle has proven >95% peak efficiency and delivers over 11,000 Nm of axle torque. The Axle is the production version of the showcased Dual EM EDU 550 eAxle, which is set to enter series production in 2026.
In addition to the high torque XXL Axle, Rimac Technology is showcasing a hybrid battery platform designed to address high-energy and power-dense demands. The company is also showcasing a portfolio of domain and zonal ECUs at IAA Mobility, powered by NXP's S32E2 real-time processors. Rimac Technology is consolidating multiple traditional ECUs into single high-performance domain controllers, simplifying complexity, reducing cost and weight, and enabling OEMs to embrace software-defined vehicles.
Nurdin Pitarević, COO of Rimac Technology, stated that the technologies showcased at IAA represent the convergence of breakthrough innovation and production readiness. In the past 12 months, global automobile manufacturers collaborating with Rimac Technology include Audi and other leading OEMs; Audi is also designated to produce the Dual EM EDU 550 eAxle in 2026.
