• RISE (Reinforced Impact Safety Evolution) has

been adopted for the main body in order to
improve all-round impact safety at high level.

• The applications of anti-corrosion steel plates

have been expanded to the doors, inner panel of
the trunk lid and reinforcements to improve the
anti-corrosive properties of the main body.

• High-tensile steel panels of 590MPa-grade and

980MPa-grade have been used for some panels
to improve collision safety and reduce weight.

The front and rear structures to absorb high energy,
and the highly tough cabin structure is adopted to
reduce the risk of passenger injuries at front-, rear-,
and side-impact collisions, secure the space for life
protection, and facilitate rescuing passengers. The
structures also have the following features:

1. The crush box structure, which has an octagonal

cross-section at the front end of the front side-
member, has been adopted. This structure can
effectively absorb energy upon frontal impact and
reduces the vehicle repair cost caused by a light
collision.

2. The front sidemember structure is changed to a

straight frame structure with an octagonal cross
section in order to improve the frontal collision
characteristics.

3. The front frame structure is supported in three

directions by the dash crossmember center, dash
crossmember lower, and front sidemember rear
in order to improve the frontal collision character-
istics, and increase the vehicle body rigidity.

4. An annular structure has been used for the side

structure reinforcement to improve collision
safety and vehicle body rigidity.

5. 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.

6. The padding structure of front fender bracket is

adopted to have a crushable structure that effi-
ciently absorbs energy upon impact, improving
the pedestrian protection capability.

STEEL PLATE WITH UNEVEN THICKNESS

The uneven thickness steel panels* (in uneven thick-
ness integrated structure) have been adopted for the
front and rear door panel inner to improve safety
upon impact and reduce weight.

NOTE: *: A steel sheet of varying thickness that is
welded into one steel sheet.
