Quick Takeaways
- Autoneum’s monomaterial polyester solutions demonstrate how sustainability and premium NVH performance can coexist in next-generation EV interiors.
- The Polestar 5 program shows supplier-led material innovation accelerating circular economy adoption in electric passenger cars.
Autoneum Holding Ltd. confirmed its role as a key supplier of lightweight recyclable EV components for the Polestar 5 electric grand tourer, unveiled at IAA Mobility 2025 and planned for availability across 24 global markets. The collaboration highlights how material innovation is reshaping sustainability, comfort, and efficiency in premium electric vehicles.
Developed over a five-year engineering partnership with Polestar, these lightweight recyclable EV components are based on monomaterial recycled polyester and are entirely latex-free. The approach delivers measurable gains in acoustic insulation and thermal performance while significantly lowering energy and water use during production. As a result, the components contribute to reduced lifecycle CO2 emissions without compromising vehicle refinement.
Lightweight Recyclable EV Components Enable Circular Design
A core strength of Autoneum’s solution lies in its monomaterial construction. By avoiding multi-material laminates, the company has simplified end-of-life processing, allowing faster disassembly and higher-quality recycling. This design philosophy also improves access to battery systems, an increasingly important requirement as EV platforms evolve toward circular economy principles.
Acoustic and Thermal Performance Without Added Weight
Despite their reduced mass, the polyester-based components deliver high acoustic damping and heat management. This balance is critical for electric vehicles, where the absence of engine noise makes wind and road sounds more noticeable. Autoneum’s lightweight recyclable EV components address this challenge while supporting overall vehicle efficiency through weight reduction.
Key Components Supplied for the Polestar 5
Autoneum provides multiple interior and exterior solutions tailored specifically for the Polestar 5, each designed to meet performance and sustainability targets:
Manufacturing Efficiency and Lower Environmental Impact
Production of the lightweight recyclable EV components requires minimal energy and water compared with conventional solutions. This efficiency directly reduces manufacturing emissions and supports automakers’ broader decarbonization strategies. For premium EVs like the Polestar 5, such gains are increasingly central to brand positioning and regulatory readiness.
By integrating sustainability, performance, and manufacturability into a single material strategy, Autoneum’s work on the Polestar 5 illustrates how supplier innovation is accelerating the transition toward circular, high-quality electric vehicles at scale.
