ZAGREB, 7 April 2026 – Croatian electric vehicle technology company Rimac Technology has reached another milestone in the global automotive industry through its partnership with BMW Group, with a jointly developed battery system set to debut in the new BMW i7.

The luxury electric sedan will make its world premiere at Auto China 2026 in Beijing on 22 April, becoming the first BMW battery electric vehicle to feature a battery system developed in collaboration with the Croatian technology company.

The advanced battery system combines BMW’s latest Gen6 cylindrical lithium-ion cells with its Gen5 module-based technology, creating a scalable architecture designed to deliver improved energy density, range and charging performance.

The system has been jointly engineered by BMW and Rimac Technology and is manufactured at the purpose-built Rimac Campus, located on the outskirts of the Croatian capital.

Spanning 90,000 square metres, the state-of-the-art campus is one of the largest industrial construction projects of its kind in Europe.

Around 15,000 square metres of the facility is dedicated specifically to the BMW programme, with around 70 percent of the site’s capacity focused on battery system production for several global automotive manufacturers.

Within just a few years, Rimac Technology has built a new production facility, industrialised two full production lines and created a complete supply chain capable of meeting the quality and volume standards required by a major premium car manufacturer.

The development highlights Rimac Technology’s growing role as a Tier 1 supplier to leading global automotive brands.

Mate Rimac, Founder and President of the Rimac Group and CEO of Bugatti Rimac, said the collaboration demonstrated the speed and capability of the partnership.

“BMW has always been known for pushing engineering to the highest level, which made this collaboration especially exciting for us. Together we developed a high-voltage battery system that unlocks the full potential of the new cylindrical cells in record time, delivering significant improvements in energy, range and charging performance,” Rimac said.

“We are proud to now see this system being produced at scale at our new Rimac Campus.”

According to Nurdin Pitarević, CEO of Rimac Technology, the project reflects a new model of collaboration between automotive manufacturers and technology companies.

“This partnership represents an important step forward in electric vehicle technology. Together we developed advanced battery technology for the BMW i7, delivering outstanding performance, efficiency and reliability,” Pitarević said.

“What makes this collaboration special is BMW’s engineering excellence and the way they approach cooperation – treating Rimac Technology not just as a supplier, but as a true technology partner.”

BMW says the project forms part of its wider strategy to roll out next-generation electric vehicle technologies across its range.
