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

E5U021334700N01

• 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.

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

• As with the front upper arm, the zero-stopper-clearance bushings optimize control over changes in vehicle 

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.
