Lightweight Vehicle and Powertrain Structures

In recent decades, the automotive industry has come to rely on a just-in-time global supply chain. Global events, such as the COVID-19 pandemic and geopolitical conflicts, have impacted the security and reliability of this global supply chain. This has raised concerns about the dependence on lowest-cost sourcing and highlighted the need to address environmental impacts. Governments are reacting to supply-chain vulnerabilities and addressing environmental concerns by introducing legislation, for example on end-of-life to increase recycling and re-use of materials. This is encouraging more local supply chains and changing how materials are sourced and what materials are used.

There is a growing demand for recycled materials and sustainable products, driven by consumer preferences for greener goods. This demand is likely to increase regardless of legislation and, as Original Equipment Manufacturers (OEMs) become more environmentally conscious, the transition to lower-embedded CO2 materials and products will become a necessity.

Advanced materials, including high-strength steels, aluminium alloys and composites, continue to play an important role depending on the requirements of the different sectors. By replacing traditional steel components with lightweight materials, vehicle weight can be reduced, leading to improved fuel efficiency.
