Mercedes integrates low carbon aluminium into EQS production
Mercedes-Benz presents first results of its low-carbon-technology roadmap. Following a successful testing phase of low carbon aluminium with a minimum 25 per cent share of post-consumer scrap, the company is bringing demanding structural cast components made of the more sustainable material into series production this year. The tested aluminium comes with a carbon footprint of just 2.8 kg CO₂ per kg of aluminium.
“On our path to achieving a net carbon neutral vehicle fleet along the entire value chain by 2039, we are reaching the next milestone: Together with our strategic partner Hydro we are bringing low carbon aluminium into our series models as early as this summer. Thereby we are reducing the CO₂ footprint of the aluminium by as much as 70 per cent compared with the European average. Among the first models to be equipped with the more sustainable material will be our EQS as well as the EQE.”

Processing of low-CO₂ aluminium for series models
Today, Hydro already supplies Mercedes-Benz with CO₂-reduced aluminium that comes from electrolysis powered by renewables. As a next milestone, Hydro will supply further, even more CO₂-reduced aluminium to the foundry at the Mercedes-Benz plant Untertürkheim (Mettingen section). This material accounts for about 60 per cent of the total aluminium used of this alloy type in the Mettingen foundry and includes a post-consumer scrap content of at least 25 per cent. In Mettingen, the material is cast into sophisticated structural components for body-in-white applications. Among other parts, the material is being used for safety-relevant components, such as the shock towers for the models EQS, EQE, S-Class, E-Class, GLC and C-Class. Furthermore, the EQE will be equipped with longitudinal members made of low CO₂ aluminium. Mercedes‑Benz also plans to use the material for various other parts such as the support frame for the electric powertrain of the upcoming vehicle platform MMA (Mercedes Modular Architecture).
