Rimac Technology unveiled a series of innovations in battery and drive systems at the IAA Mobility 2025 show in Munich on Monday, including a solid-state battery developed with ProLogium and the Mitsubishi Chemical Group.
The Croatian company, a subsidiary of Rimac Group, presented what it described as next-generation solutions designed for large-scale production. “What we’re showcasing at IAA represents the convergence of breakthrough innovation and production readiness,” said Nurdin Pitarević, Rimac Technology’s chief operating officer. “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.”
The new solid-state battery platform combines cells from Taiwan’s ProLogium with advanced materials from the Mitsubishi Chemical Group, aiming to create a lightweight, energy-dense and safer solution. Rimac also introduced its Evo battery platform using 46XX NMC round cells and a thermoplastic composite housing, which it described as “the immediate future of high-performance battery systems.” A third platform targets hybrid batteries with high energy density and improved safety.
On the drivetrain side, Rimac highlighted its Sinteg 300 & 550 electric axles, designed for performance vehicles with power density above eight kW per kilogram and torque density exceeding 90 Nm per kilogram. The company also presented the Dual EM EDU 550, a high-torque axle with over 11,000 Nm, scheduled for series production from 2026 for an undisclosed global automaker.
In electronics, Rimac showcased domain and zone control units built around NXP’s S32E2 processor, enabling centralized architectures to cut complexity and costs. The units manage functions ranging from torque vectoring to high-voltage battery systems, with built-in safety and over-the-air updates.
Rimac Technology is fully owned by Rimac Group, which also controls a 55% stake in Bugatti Rimac alongside investors such as Porsche, Softbank, Hyundai and Goldman Sachs. The company has also signed partnerships with BMW and Saudi-backed Ceer Motors in recent years.
