BMW i7: New Battery Technology and Sustainable Production Significantly Reduce CO₂ Footprint

With the new BMW i7, the BMW Group is consistently advancing its sustainability strategy. The focus is on innovations in battery technology, increased use of secondary materials, and improved efficiency in both production and vehicle operation.

Next-generation battery cells with lower CO₂ footprint

A key highlight is the introduction of the sixth-generation battery cells (Gen6), which reduce the CO₂e footprint in the supply chain by around 33 percent compared to the previous Gen5 cells used in earlier BMW i7 models.

This improvement is achieved through the exclusive use of renewable energy in cell production, including the manufacturing of anode and cathode materials. In addition, secondary raw materials are partially used for lithium, nickel, and cobalt.

Increased use of recycled materials

BMW is also expanding the use of secondary materials beyond the battery. From 2026, selected wheel designs for the BMW i7 will consist of up to 70 percent recycled aluminium.

The production of primary aluminium and wheel manufacturing processes increasingly rely on renewable energy, while maintaining BMW’s high quality standards.

Enhanced efficiency during vehicle operation

Sustainability efforts also extend to the vehicle’s usage phase. BMW’s EfficientDynamics technology package optimizes efficiency across key systems, including aerodynamics, lightweight construction, rolling resistance, and overall energy management.

This approach has been continuously developed since 2007 and is applied across all drivetrain technologies.

Production powered by renewable energy

All variants of the new BMW 7 Series, including the i7, are produced at the BMW Group plant in Dingolfing, Germany. The facility sources 100 percent of its purchased electricity from renewable energy.

BMW is also expanding on-site energy generation, including a large rooftop photovoltaic system with nearly 11 MWp capacity covering around 100,000 square meters, as well as a biomass heating plant supplying renewable heat.

Transparency through the Vehicle Footprint

BMW provides transparency on the environmental impact of its vehicles through its TÜV-certified “Vehicle Footprint.” This report covers the full lifecycle emissions and is available online as well as via the My BMW app.

Long-term sustainability targets

These measures contribute to the BMW Group’s broader climate goals. By 2030, the company aims to reduce its CO₂e emissions by at least 40 million tonnes compared to 2019 levels. The long-term objective is to achieve climate neutrality across the entire value chain by 2050 at the latest.
