Rimac Solid-State Battery 2026: IAA Munich 2025 Unveils Game-Changing EV Tech
Rimac Technology just dropped a bombshell at IAA Munich 2025, and I’m totally geeking out. As a car nerd who’s been obsessed with EVs since forever, their new solid-state batteries and next-gen e-axles are straight-up revolutionary. They’re not just tinkering in a lab—these are production-ready innovations set to power the future of electric cars. With collabs like BMW, Porsche, and CEER Motors in their corner, Rimac’s cementing its spot as a top-tier EV tech supplier.
From lighter, safer batteries to e-axles that pack a punch, here’s the lowdown on Rimac’s Munich showcase and why it’s a big deal for 2026 and beyond.
Rimac’s Big Play: Leading the EV Charge
Rimac’s been killing it as a Tier 1 supplier, and their IAA Munich 2025 booth (Stand C-22, Hall A1) was proof. They’re scaling up to pump out tens of thousands of units monthly at their massive 95,000 m² Croatia facilities, including the €200M Rimac Campus. Partnerships with heavyweights like BMW and Porsche show they’re not just talk—these guys are ready to electrify the auto world with cutting-edge tech.
COO Nurdin Pitarević said it best: this isn’t just concept stuff; it’s ready to roll into hundreds of thousands of vehicles soon. Let’s dive into what they brought to Munich.
Solid-State Batteries: The Future Is Here
Rimac’s battery game is next-level, and their solid-state tech, developed with ProLogium and Mitsubishi Chemical Group, is a standout. These batteries are lighter, safer, and pack more energy density than ever, pushing the limits of EV performance. ProLogium’s solid-state cells paired with Mitsubishi’s material expertise make this a game-changer for range and safety.
Then there’s the Evo Technology platform, using 46XX Gen2 NMC cells with a slick thermoplastic composite housing (called Pentatonic, co-developed with Kautex Textron). It’s all about high performance with top-notch thermal management. Rimac also showed off hybrid battery packs—46XX for high energy, 2170 for power density—both with cell-to-pack designs for scalability and safety. These are ready to hit the road now, not just in 2026.
Next-Gen e-Axles: Power Meets Efficiency
Rimac’s powertrains are where things get wild. The SINTEG 300 and 550 e-axles are super compact, fitting in carry-on luggage but delivering over 8 kW/kg power density and 90 Nm/kg torque density. With a patented ultra-light rotor spinning up to 25,000 rpm, these bad boys offer 150–360 kW and 2,500–6,250 Nm for everything from hot hatches to SUVs.
The High Torque XXL Axle, a dual-motor beast, is set for production in 2026 for a global OEM. It’s got over 95% peak efficiency and a massive 11,000 Nm of torque. Built on Rimac’s Scalable Powertrain Platform, it’s backed by a global supply chain and will roll out from their Zagreb factory. This is the kind of tech that makes EVs feel like supercars.
Smart Electronics: The Brain of Tomorrow’s EVs
Rimac’s also flexing with their electronics, using NXP’s S32E2 processors for domain and zonal ECUs. These consolidate multiple traditional ECUs into one, cutting weight, cost, and complexity while enabling software-defined vehicles. They handle everything from torque vectoring to battery management, with over-the-air updates and top safety standards. It’s like giving EVs a super-smart brain for the road.
Why Rimac’s IAA Munich 2025 Reveal Is Huge
Rimac’s solid-state battery 2026 plans and next-gen e-axles are setting the stage for a new era of EVs. Their work with ProLogium, Mitsubishi, and Kautex, plus collabs with BMW and Porsche, shows they’re not just innovating—they’re ready to dominate. The Croatia production muscle means these techs will hit the streets soon, powering everything from sporty coupes to family SUVs.
What’s got you stoked—those solid-state batteries or the crazy torque of the XXL axle? Drop a comment and let’s nerd out. Head to Rimac’s site for more details, and keep an eye on their Stand C-22 at IAA Munich 2025 for the full experience.
