FRONT SUSPENSION OUTLINE

E5U021300000N01

• An in-wheel-type double-wishbone suspension has been adopted to take full advantage of the low bonnet line

enabled by the optimized engine layout.

• The front upper arm and the front lower arm have been lengthened and attached to the highly rigid front

crossmember to allow for linear alignment changes during jounce and rebound of the front wheels. Due to this,
roadholding and handling performance have been improved.

Improved roadholding

• The heightened damper lever ratio has improved the efficiency of shock absorber operation.

— Damper lever ratio:

shock absorber stroke (B)/wheel vertical
stroke (A)

— The heightened damper lever ratio has made

it possible to provide a damping force even
during minute strokes. As a result, excellent
roadholding is exhibited in a variety of driving
conditions.

Optimized roll axis position

• The height of the front roll center is set lower than

the rear.

• Change of roll center height in response to a

change in wheel stroke has been suppressed in
order to improve roll linearity and convergence.

FRONT SHOCK ABSORBER CONSTRUCTION

• The high-pressure gas-filled monotube shock

absorber minimizes cavitation and provides
stable damping force even during hard driving.

— The large-diameter piston ensures superior

response during minute strokes, providing
consistent damping force and stroke feeling.

— The enlarged piston port area also contributes

to the improvement of riding comfort.

FRONT UPPER ARM CONSTRUCTION

E5U021334200N01

• The front upper arm is made of aluminum for improved rigidity and weight reduction.

• The zero-stopper-clearance rubber bushings have been adopted for where the upper arm attaches to the front

crossmember.

— The stopper sleeve, integrated with the inner pipe, protrudes slightly.

— This structure suppresses forward-backward movement caused by external forces acting on the arm.

— It also enables linear spring characteristics of the bushings from an early stage, thereby optimizing control

over changes in vehicle behavior.

behavior.

FRONT CROSSMEMBER CONSTRUCTION

E5U021334800N01

• A lightweight, highly rigid front crossmember with integrated side members has been adopted.

• The transverse member is attached to the back of the front crossmember to create a highly rigid square

construction.

• This front crossmember component is rigidly mounted to the vehicle body at eight points, providing an

extremely large amount of suspension support stiffness and alignment precision.
