• Aluminum front bumper reinforcement has been

equipped to improve steering stability and riding
comfort, and reduce weight and vibration noise
(rear bumper reinforcement is made of steel).

• The front and rear bumpers incorporate highly

rigid bumper reinforcements and bumper cores
for excellent energy-absorption to reduce chassis
deformation upon impact.

• With the front and rear bumper reinforcements

remaining on the body, front and rear bumpers
can be removed as a unit.

• Resin-made front bumper side brackets and rear

bumper face support brackets have been
adopted to improve the alignment with the body.

• Rear bumper protector and rear bumper core

center have been added to the rear bumper
assembly. <Vehicles for Canada>

AERO PARTS

EXTERIOR

51-5

The following aero parts provide better aerodynamic
performance and an appealing look.

• Hood end shape:

Upper section of front bumper also serves as the
hood end, reducing the air resistance by shape
optimization.

• Front bumper and air dam skirt panel:

Lower end of front bumper has been lowered.
With the mounting of air dam skirt panel, an edge
shape is given to the lower end of bumper. This
shape alteration reduces the airflow entering
under the vehicle to decrease the air resistance
and lifting force exerted to the vehicle front. The
resulting improvement to the front tire traction
provides enhancements to driving stability during
high speed traveling.

• Air dam shape at front of front wheel arch:

The bumper corners at the front of front wheel
arch has been made to have a projecting air dam
shape to separate the airflow at side of the body.
The generated negative pressure lowers the air
pressure in the wheel housing, reducing the lifting
force at the vehicle front.

• Lip shape at rear of front wheel arch:

The lip section at the rear of front wheel arch has
been bent inward to facilitate venting of air from
the wheel housing, decreasing the lifting force
and air resistance at the vehicle front.

• Under floor:

The under cover mounted to the under floor has
been flattened and arranged at correct position to
smoothen the airflow entering under the floor for
a reduction of air resistance. At the same time,
the lifting force is reduced to suppress the lifting
of vehicle during high speed traveling.

• Side air dams:

Smoothens the airflow under the floor and around
the wheels to decrease the air resistance and lift-
ing force.

• Rear spoiler:

<Standard type>
Separates the air vortex induced at the rear of the
vehicle to smoothen the airflow. In addition, the
enlarged horizontal wing and the helix angle have
been optimized to reduce the air resistance and
to generate the down force, thus, the road hold-
ing quality of rear tires has been increased to
improve the driving stability while driving at high
speed.
<Large type>
The base shape of wing has been optimized to
match the airflow. Furthermore, the wing's angle
of attack has been modified at the center and
both ends, adopting a twisting structure to gener-
ate down force to the airflow for a reduction of lift-
ing force at the vehicle rear. At the same time, the
rear tire traction is enhanced to improve the driv-
ing stability during high speed traveling.
