MULTI-LINK REAR SUSPENSION CONSTRUCTION

Optimized Link and Shock Absorber Layout

Optimized camber angle
• Change of camber angle to ground during wheel stroke is minimized due to the optimization of the lower and
upper arm lengths. Due to this high gripping power is assured under any driving condition and handling stability
is improved.
Camber control characteristic comparison
Optimized roll axis position
• Lateral force acting on the shock absorbers is reduced due to the separated positioning of the rear coil spring
and shock absorber, enabling smooth operation of the suspension system and thereby improving riding
comfort.
• Additionally, the height of the front roll center is set lower than the rear. Due to this, driveability is improved
while cornering.
FRONT ROLL CENTER HEIGHT
Improved roadholding
• The damper lever ratio has been set at approx. 1.2 to improve the efficiency of the shock absorber operation.
