Constellium Completes FlexCAR Project, Advances Modular Sill Concept with Recycled Aluminum.

Constellium SE has completed the FlexCAR project, a five-year innovation effort with ARENA2036 to create a modular platform for vehicle systems. The platform envisions easily configurable or updatable drivetrain, energy storage, and interior systems. Constellium developed a modular sill concept using high-strength aluminum alloys with significant recycled content to ensure safety and performance standards. The project was completed with partners Mercedes-Benz, Siemens, Bosch, and the German Aerospace Center (DLR).

Constellium SE (NYSE: CSTM) has successfully completed the FlexCAR project, a five-year innovation effort in collaboration with ARENA2036, Germany’s leading research campus for future mobility and production technologies. The FlexCAR platform envisions a future where major vehicle systems—such as the drivetrain, energy storage, and interior—can be easily configured or updated. Constellium developed a modular sill concept using high-strength aluminum alloys with significant recycled content to ensure safety and performance standards [1].

The project was completed with partners including Mercedes-Benz, Siemens, Bosch, and the German Aerospace Center (DLR). The modular sill concept, designed to support various powertrains including battery electric and hydrogen fuel cell vehicles, offers enhanced crash performance, design flexibility, and a lower carbon footprint over the vehicle’s lifecycle [2].

Constellium’s previous Digital Fingerprint project with ARENA2036 also resulted in the development of a digital twin system for tracking aluminum component performance throughout its lifecycle. This technology supports predictive maintenance and accelerates development cycles, demonstrating Constellium’s commitment to data-driven manufacturing [3].

The FlexCAR project positions Constellium at the forefront of the evolving automotive market by addressing key industry priorities such as lightweighting, safety performance, design flexibility, and sustainability. The modular aluminum structures developed by Constellium could significantly strengthen their position as automotive manufacturers increasingly seek suppliers capable of solving multiple challenges simultaneously [2].

Constellium’s ability to secure long-term development resources through publicly funded projects underscores their strategic approach to innovation and market leadership. The company’s focus on modular thinking combined with the performance and sustainability benefits of aluminum alloys highlights their commitment to driving forward the future of automotive technology.
