A door hinge assembly is mounted between a door mounting pillar of the
vehicle body and a door to swingably mount the door to the door mounting
pillar. The door hinge assembly includes an upper hinge and a lower hinge
with a double pivot pin arrangement, and a torsion bar extending
substantially vertically between the upper and lower hinges. The upper
and lower hinges are fastened at interior fastening points on an inner
side wall of the door mounting pillar and at exterior fastening points on
an exterior wall portion of the door mounting pillar with longitudinal
fastening axes that extend in a substantially orthogonal direction to the
inner side wall and the exterior wall portion of the door mounting
pillar. The interior fastening points are disposed rearwardly of the
torsion bar and the exterior fastening points are disposed forwardly of
the torsion bar.
