S-in motion^® for mid-size sedan and SUV

The automotive landscape is rapidly evolving, driven by the electrification of vehicles and the emergence of new market players. As carmakers navigate the complexities of balancing internal combustion engine (ICE) and battery electric vehicle (BEV) production, ArcelorMittal’s Multi Part Integration^® (MPI) offers a transformative approach. This white paper discusses how MPI technology helps streamline automotive manufacturing, reduce the number of parts, and achieve significant CO2 savings—all while meeting stringent performance standards for safety and lightweighting.

David Clarke, ArcelorMittal’s head of strategy and chief technology officer, highlights the impact materials have on our planet, and how are we to mitigate the risks, while responding to the global demand for steel.

ArcelorMittal is transforming the auto industry from the inside out. ArcelorMittal, the world’s leading steel and mining company, is continually developing lightweight steel solutions that make vehicles lighter, safer and more sustainable.

Automakers trust ArcelorMittal to help them create the safer, lighter, cleaner vehicles of tomorrow, wherever they are in the world. We are proven global technical leaders and innovators, working in close collaboration with our customers right from the start.

To prove the validity of the MPI concept, teams from ArcelorMittal Tailored Blanks and ArcelorMittal Global R&D have developed a new LWB H-Frame solution for the rear of an SUV vehicle. The S-in motion^® SUV was used as the basis for the design.

ArcelorMittal has been working with automakers for years to co-engineer steel solutions that address safety, strength and fuel economy concerns in the most cost-effective way. ArcelorMittal offers an array of lightweight steel solutions and has seen tremendous growth and evolution of its door ring solution, co-engineered with Honda R&D Americas.

Zagnelis^® coatings have been specially designed to add a stage in vehicle corrosion protection, while meeting vehicle manufacturers' specifications: drawing, welding properties etc. In particular, they offer corrosion resistance far superior to that provided by traditional zinc-based coatings. The presence of magnesium in the coating promotes the formation of compact corrosion products highly stable over time, thereby substantially reducing coating consumption dynamics and enhancing edge protection.

Zagnelis^® coatings also offer excellent drawability performance due to outstanding tribological properties for a zinc-based coating.

Steel recycling and sustainability go hand-in-hand

As the world becomes even more connected, the need for sustainable, carbon-neutral mobility solutions has never been greater than it is today. And while those solutions will look very different to the mobility options we use now, smarter steels will still play a crucial role. Whether it is in autonomous, connected, electrified, or shared solutions, high strength and innovative steels will remain key to mobility.

ArcelorMittal is proud to spotlight its collaboration with Renault, and its contribution to the innovative Renault Emblème project, a demo car designed to meet the challenges of low-carbon mobility. This collaboration demonstrates how the automotive and steel industries can unite to achieve ambitious decarbonisation goals, showcasing a reduction of CO₂ emissions compared to conventional steelmaking by as much as 69%. 

For the transition to electric vehicles to be fully successful, carmakers must increase efforts to extend range, reduce cost, and enhance safety. A new S-in motion^® study from ArcelorMittal reveals that advanced high strength steels (AHSS) solutions are the best choice to achieve this revolution in mobility at an affordable cost. The first part of this study focuses on battery pack solutions.
