SIDE STRUCTURE

• The 590-MPa class high tensile strength steel 

panels or 980-MPa class ultra high tensile 
strength steel panels have been adopted for the 
front pillar, center pillar, side sill, and roof side rail 
to improve the body rigidity.

• Rigidity was heightened and driving stability was 

improved by bonding the roof bow and roof rail 
and the roof side rail inner by the roof rail exten-
sion.

• A rear shelf lower brace is used to connect the 

spring house middle panel and rear shelf upper 
brace, so that the body rigidity, handling stability, 
and riding comfort are improved.

• The number of the spot welding points at the door 

opening has been increased to heighten the body 
rigidity and to improve handling stability.

• An aluminum roof panel has been adopted to 

improve lightweightness for greater handling sta-
bility. <Vehicles without sunroof (aluminum 
panel)>

• The closed section structure has been adopted 

for the roof rail front and the roof bow center to 
heighten body rigidity, improve handling stability 
and riding comfort, and to reduce vibration and 
noise.

• The 590-MPa class high tensile strength steel 

panel has been adopted for the roof bow center 
lower to improve the body rigidity. <Vehicles with-
out sunroof (aluminum panel)>
