Exterior Sill/Rocker Structure
The sill/rocker structure represents the principle load path from the front section to the
rear. To provide rigidity against bending and torsion forces, a horizontal flange has been
added between the inner and outer sill/rocker beam shell. The sill/rocker structure is addi-
tionally reinforced with the incorporation of transverse reinforcing components.
