Key features:

  • Longitudinal member for Mercedes-Benz E-Class (Coupé and Convertible)
  • Important structural part of a sidewall within body-in-white
  • Following information are based on Longitudinal member Convertible LH:

    • Number of weld spots: 115
    • Number of adhesive seams: 11
    • Material thicknesses between 1.25 mm and 2.75 mm (main part of Longitudinal member)
    • Total part length: 2100 mm
    • Total weight: 20 kg


  • Production process with high complexity – all 4 versions of “Longitudinal member” (Convertible LH and RH, Coupe LH and RH) are manufactured in one cell. Each version differs in the number of single components, number of weld spots and length of adhesive application.
  • Additional part generates higher stiffness in convertible parts
  • Expanding foam elements are disrupting the air flow to reduce driving noise
