Discover the power of less with MPI
In a rapidly evolving automotive industry, flexibility wins. ArcelorMittal Multi Part Integration® maximises automotive manufacturers’ ability to adapt through the power of less: less parts, less process, less floor space, less time, less materials, less CO₂ and less assembly cost.
Harness the strength of steel and the power of less.
MPI uses ArcelorMittal's PHS and patented laser-welding technology to streamline manufacturing and reduce assembly complexity by maximising part integration. This modular solution can be applied across all powertrains and can be used to simplify the design and production of the battery pack, chassis, and body-in-white applications for e-mobility and micro-mobility.
Each MPI module streamlines production, reduces assembly complexity, saves weight, and shortens lead times. These efficiencies have tangible financial benefits, with operational and capital expenditure savings.
Developed in close collaboration with OEMs worldwide, MPI draws on ArcelorMittal’s global reach, track record of innovation, and breadth of experience within the industry. MPI delivers the flexibility today's automotive manufacturers need, as they develop futureproof strategies and rapidly adapt to grow their local and international footprint.
Multi Part Integration® (MPI)
ArcelorMittal’s MPI concept has already been applied to several vehicle parts across projects in three key regions: North America, China, and Europe. The results of the studies show that for every part produced using the MPI concept, significant emission, cost, and process savings are generated. Engineering firms such as Bertrandt and Kuka have provided support in the calculation of these savings.
Benefits
Based on 6 MPIs combined. If we add other MPIs, performance and savings are likely to increase.
Cost saving
Innovative efficiency for maximum cost impact:
MPI enhances cost-effectiveness through strategic material optimisation, streamlined tooling processes, minimised welding, and competitive capital expenditure benefits.

Modularity
Versatile modularity for maximum flexibility
MPI's compatibility with multiple OEM platforms and all PHS steel grades / thicknesses enables versatile and flexible manufacturing, allowing OEMs to maintain adaptability across various vehicle types and both existing and new manufacturing lines.
Sustainability
Eco-friendly engineering for a sustainable tomorrow
MPI steel solutions reduce CO2 emissions for improved Life Cycle Assessment, optimise material utilisation and nesting while leveraging steel's inherent circularity, paving the way for greener automotive production.
Weight saving
Advanced lightness for optimal performance
MPI is an innovative lightweight steel solution that optimises the vehicles BiW mass by consolidating multiple parts. A core advantage is the compatibility with all high-strength steel grades, providing the highest lightweighting potential.
Safety
Enhanced safety for unmatched crash protection
MPI optimises anti-intrusion and energy absorption by using the right steel grade in the right place while applying ArcelorMittal Tailored Blanks proprietary laser ablation technique, ensuring superior protection and safety for every vehicle.
Featured case studies
Case studies
ArcelorMittal’s MPI concept has already been applied to several vehicle parts. The results of the studies show that for every part produced using the MPI concept, significant emission, cost, and process savings are generated.
The following MPI case studies are already complete:
- Dash panel
- Double door ring
- Floor reinforcement
- Rear floor panel
- Rear H-frame
Further studies are under development. The results will be published on this page as they become available. We’re also interested to hear where you'd like to apply MPI in your vehicles.
