FRONT SIDEMEMBER REINFORCEMENT

• The front sidemember structure has been

changed to a straight frame structure with an
octagon cross section that efficiently absorbs
energy from the impact at the time of collision.

• The front sidemember is supported in three direc-

tions by the dash crossmember center, dash
crossmember lower and front sidemember rear in
order to improve the frontal collision characteris-
tics, and increase the vehicle body rigidity.

• The 590-MPa class high tensile strength steel

panels have been adopted for the front sidemem-
ber extension, front sidemember rear bulkhead
and front sidemember rear to improve the body
rigidity.

FRONT DECK

• The impact absorbing opening on the cowl top

outer reinforcement upper has been added to effi-
ciently absorb energy upon impact and improve
the pedestrian protection capability.

• Rigidity was heightened and driving stability was

improved by bonding the fender shield frame
upper outer and front pillar by the upper frame to
front pillar brace.

DASH PANEL

The 590-MPa class high tensile strength steel panels
have been adopted for the dash crossmember cen-
ter, dash crossmember extension, dash panel rein-
forcement and dash crossmember side to improve
the body rigidity.
