A surprising revelation came out of the 2025 IAA Munich Auto Show, one that connects two of the world’s most advanced automotive names. Porsche’s new 911 GTS T-Hybrid, which has been drawing attention for blending classic sports car DNA with hybrid technology, is powered by a battery pack built by none other than Rimac.
For those who may not recognize the name right away, Rimac is the Croatian company best known for building all-electric hypercars and for developing the advanced hybrid system inside the Bugatti Tourbillon. This means Porsche’s hybrid 911 doesn’t just share some vague connection to eco-friendly hybrids like the Toyota Prius. It carries DNA from the same company that helps produce Bugatti’s multi-million-dollar machines.
A Quiet Partnership Finally Revealed
It turns out that Rimac’s involvement wasn’t exactly hidden, but it also wasn’t widely publicized. Anyone who had carefully inspected the 911 GTS T-Hybrid’s front trunk, where the battery sits, might have noticed Rimac branding. Yet until this week, most enthusiasts and journalists hadn’t connected the dots. The confirmation finally came at Rimac’s booth at IAA Munich, where the company displayed the very same battery pack.
The display placard revealed key details:
- The pack weighs 60 pounds.
- It has a 1.9-kilowatt-hour capacity.
- It operates on a 400-volt system, with voltage levels ranging from 270 to 453 volts, depending on its state of charge.
- It can discharge power at a rate of 50 kilowatts.
These numbers may sound like raw specs, but they translate to real performance. In hybrid systems like Porsche’s, a relatively compact and lightweight battery is critical. It allows for quick power boosts when needed, without adding excessive weight to the sports car.
Inside the Battery Design
Rimac also shared a cutaway model of the pack at the show, giving enthusiasts a look inside. The unit contains 2,170 cylindrical NMC (nickel manganese cobalt) cells arranged on two levels. Cooling is handled through an indirect system using water and glycol, ensuring the pack stays at safe operating temperatures even during hard driving.
This setup reflects the kind of engineering Rimac is known for, technology designed not just for efficiency, but for high performance. It’s the same philosophy that goes into their hypercars and the hybrid Bugatti Tourbillon.
Changing the Hybrid Conversation
The news is likely to give Porsche fans fresh ammunition in the hybrid debate. For years, critics have compared hybrid sports cars to everyday commuter hybrids like the Prius, suggesting the performance world was losing its edge in the name of efficiency. However, with Rimac supplying advanced systems to both Porsche and Bugatti, the story takes a dramatic turn.
Instead of being about compromise, this new era of hybrid sports cars shows how technology can elevate performance. The Porsche 911 GTS T-Hybrid, thanks to Rimac’s battery, is closer in spirit to a Bugatti hypercar than to a basic family hybrid.
What This Means Going Forward
This partnership highlights how Porsche continues to evolve the legendary 911 without losing its identity. The brand has managed to integrate modern hybrid tech in a way that supports speed, handling, and everyday usability, all while working with one of the most innovative companies in the industry.
For Rimac, this is another major milestone. Once known only for its boutique hypercars, the company has grown into a crucial supplier for big names like Bugatti and Porsche. It’s clear that Rimac’s influence in the automotive world is expanding, and its advanced battery systems will likely appear in even more high-end models in the future.
At the end of the day, this revelation at IAA Munich shows that hybrid doesn’t have to mean boring or compromised. In fact, in cars like the 911 GTS T-Hybrid, it means the opposite: more power, more innovation, and stronger ties to the hypercar world than ever before.
