16 Apr Sustainability is key part of the new BMW i7 production.
(Oilandgaspress) -– BMW Group is once again systematically leveraging product sustainability innovations in the new BMW 7 Series. This is evident, for example, in the use of a new battery cell technology and a higher percentage of secondary material in the wheel rims. These measures represent a targeted further development, applying proven sustainability approaches to another BMW model.
Sixth-generation (Gen6) battery cells in the new BMW i7: Measures to reduce CO2e in core component.
Essential levers for reducing supply chain CO₂e emissions include increased use of secondary materials and renewable energies, in combination with selected product and process innovations.
Gen6 battery cells for the BMW i7’s high-voltage battery are manufactured exclusively using energy from renewable sources. The same applies to production of the necessary anode and cathode active material. Cell production also relies in part on secondary raw materials for the lithium, cobalt and nickel required. This reduces the overall supply chain CO2e footprint of the Gen6 battery cell in the new BMW i7 60 xDrive by approximately 33 percent compared to the previous Gen5 cell used in the BMW i7 to date.
Aluminium wheels with high percentage of secondary raw materials.
From 2026, selected rim designs for the BMW i7 will be available with 70 percent secondary aluminium. Electrolysis of the remaining primary aluminium, as well as wheel rim production, is carried out in part using renewable energy. All components with a high percentage of secondary raw materials meet the BMW Group’s same strict quality standards, while also contributing to resource efficiency.
