• 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

TSB Revision

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.
