Audi, Aluminum, Environment
As OEMs transform their propulsion systems to electrification and full electric, many of them are taking the opportunity to implement even more environmental procedures than has been the case.
For example, the Audi e-tron, the brand’s first fully electric vehicle, is being provided with aluminum for its battery housing by materials supplier Hydro that is, according to Audi, “processed and manufactured along the entire process chain in an environmentally friendly manner and under socially acceptable working conditions.”

And this isn’t just a claim that sounds good: there is confirmation by the Aluminium Stewardship Initiative (ASI), an organization that tracks the development of the non-ferrous material from the mining of bauxite to the production of the material.
From the point of view of a lifecycle assessment, Audi plans to reduce the carbon-dioxide emissions of its vehicles by approximately 30% in 2025 compared to the level in 2015.
What’s more, according to Dr. Bernd Martens, Audi Board of Management member for Procurement and IT, “We want to offer our customers completely CO2-neutral mobility by 2050 at the latest. To do that, we need a sustainable supply chain.”
The e-tron is produced at the Audi plant in Brussels, Belgium, which the company says is a CO2-neutral facility.
Generally, when OEMs produce aluminum engine blocks (aluminum rather than cast iron because cast iron weighs like cast iron), they insert sleeves into the piston bores—cast iron sleeves.
