Rimac Debuts Solid-state Batteries and E-axles at IAA
Rimac Technology unveiled a new portfolio of advanced EV battery and electric powertrain technologies at IAA Mobility 2025 in Munich, including next-generation solid-state solutions and evolved versions of its current batteries and e-axles. These technologies strengthen Rimac Technology’s position as a leading Tier 1 supplier supporting the electrification of the automotive industry.
Over the past 12 months, the company has announced major collaborations with global automotive OEMs, including BMW Group, CEER Motor, and Porsche, and continues to innovate for near-term applications. The business now builds capacity to produce tens of thousands of units per month while ensuring every product remains at the cutting edge.
At IAA, Rimac showcases breakthrough battery, powertrain and electronics platforms that advance energy density, safety and performance for software-defined vehicles. In next-generation batteries developed in collaboration with ProLogium and the Mitsubishi Chemical Group, Rimac integrates solid-state cells and advanced materials into a lighter, safer, and more energy-dense system. In the Evo platform, based on 46XX Gen2 NMC cells, Rimac pairs proven chemistry with a next-generation thermoplastic composite battery housing (Pentatonic), co-developed with Kautex Textron, to improve packaging and thermal management. The Hybrid platform leverages proven technology to address two key needs: high-energy hybrid battery packs utilising the 46XX cell format and power-dense hybrid packs utilising the 2170 cell format. It offers dimensional scalability, interchangeable cell configurations and cell-to-pack architecture with advanced safety and thermal management.
Rimac also presents new electric powertrains. The SINTEG 300 and 550 Single EM ultra-compact, fully integrated e-axles deliver power density exceeding 8 kW/kg and torque density surpassing 90 Nm/kg, setting fresh benchmarks for series applications. A patented ultra-light rotor spins up to 25,000 rpm, and a novel magnet design delivers exceptional torque and power in a package small enough to fit in carry-on luggage. Built on Rimac Technology’s Scalable Powertrain Platform, CoAxial or Offset variants offer power outputs ranging from 150 to 360 kW and torque outputs of 2,500 to 6,250 Nm, catering to performance-focused vehicles, including hot hatches, sports coupés, saloons, and SUVs.
The High Torque XXL Axle represents the production version of the showcased Dual EM EDU 550 e-axle, which is set to enter series production in 2026 for a global OEM. The validated system achieves a peak efficiency of over 95% and delivers more than 11,000 Nm of axle torque. A mid-volume series programme, it benefits from a robust global supply chain, with a highly automated industrialisation line scheduled to go live at a Rimac Technology production facility on the outskirts of Zagreb, Croatia.
In electronics and controls, Rimac showcases a state-of-the-art portfolio of domain- and zone-specific ECUs powered by bNXP’s S32E2 real-time processors. By consolidating multiple traditional ECUs into single high-performance domain controllers, the company enables a centralised architecture that reduces complexity, cost and weight while accelerating the shift to software-defined vehicles. These next-generation ECUs manage functions from torque vectoring and high-voltage battery systems to body and power distribution controls, delivering safety, scalability, real-time performance and OTA updates.
Rimac will produce the technologies unveiled at IAA Mobility at its facilities in Croatia, which provide more than 95,000 m² of production space across two sites. The flagship Rimac Campus represents an investment of over €200 million in advanced manufacturing capabilities, providing the scale and sophistication to support multiple high-volume projects simultaneously.
"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."
Visitors to IAA Mobility can experience the complete portfolio at Stand C-22 in Hall A1, where the Rimac Technology team will discuss technical details and partnership opportunities.
