Inward penetration of the doors during a side-impact collision is prevented by directly connecting the upper and lower side-impact bars of the front doors directly to the front door hinge using bolts and positioning them such that they overlap the center pillar.
Inward penetration of the doors during a side-impact collision is prevented by directly connecting the lower side-impact bars of the rear doors directly to the rear door hinge using bolts and positioning them such that they overlap the side sill.
