Overview
- BMW and Rimac said Tuesday they jointly developed a Gen6 high‑voltage battery for the updated i7, which will premiere on April 22 at Auto China in Beijing.
- The pack pairs BMW’s 4695 cylindrical cells with the brand’s Gen5 module design in a scalable layout, with BMW citing about 20% higher volumetric energy density than previous prismatic cells.
- Rimac will assemble complete battery packs at its Zagreb campus and ship them to BMW’s Dingolfing plant in Germany for installation in the 7 Series line.
- BMW has not released the new pack’s capacity, certified range, or peak charging figures, though it says charging will be faster than today’s 195 kW limit on the current i7.
- Both companies describe the partnership as long term, and outlets report the same battery architecture is likely to migrate to other BMW EVs, with the 2027 i5 facelift named as a leading candidate.
