Electrifying S-in motion®

Advanced high strength steels (AHSS) have again proved their value – this time in a lightweight solution for electric vehicles. The project is particularly relevant for carmakers who wish to create electric versions of their conventional vehicles.

In the electric S-in motion® solution, the BIW was redesigned to accommodate the larger electric powertrain and battery protection required. Extensive use of AHSS (up from 35 to 58%) enabled ArcelorMittal’s engineers to reduce the weight of the electric BIW by 30 kg (11%).

ArcelorMittal’s S-in motion® project has already demonstrated the potential of AHSS to lighten the body-in-white (BIW) and chassis of fuel-powered vehicles. But electric vehicles present a completely new set of challenges for automotive designers.

ArcelorMittal’s electric S-in motion® solution:

  • Provides lightweight solutions carmakers can implement today in their electric vehicles
  • Has been adapted for a completely different powertrain
  • Provides extra battery protection without adding mass
  • Maintains crash performance
  • Makes extensive use of AHSS to deliver weight savings.
