CHASSIS — SUSPENSION

3. Stabilizer Bar

The mounting position of the stabilizer link has been changed from the lower arm to the strut.
As a result of realizing rolling control and excellent steering feeling, the spring rate of the coil spring could
be lowered to improve riding comfort.

4. Suspension Upper Support, Coil Spring and Shock Absorber

The spring rate and damping force have been revised to realize excellent riding comfort, in addition, this
provides excellent stability and controllability.



 REAR SUSPENSION

1. General

As in the previous model, the new model uses MacPherson strut type independent suspension.
However, each part of suspension has been revised to realize excellent riding comfort, in addition, this
provides excellent stability and controllability.

2. Geometry



The position of the lower arm where it mounts to the subframe has been raised to relocate the rear roll
center higher than that of previous model. As a result of this change, the body roll is restrained when a
lateral force is applied, such as during cornering and lane changes, thus realizing excellent stability and
steering response.



The negative camber angle realizes excellent stability during cornering and lane changes.

 ELECTRIC MODULATED SUSPENSION

1. General

An electric modulated suspension is available as an option on all models.
