Front Suspension

VARIATION IN CAMBER DURING CORNERING
When the steering wheel is turned, camber varies
as shown below because of increased caster angle
and reduced kingpin angle. On the vehicle with
link suspension, the change in “camber to ground”
caused by the body rolling during cornering is small

by the same action as the one experienced in a

provide outstanding directional stability by making

OPERATION <TURBO>
When the shock absorber piston speed is at less
than 0.1

the control of the damping force

is impossible with the conventional fixed opening
orifice alone. This control has been made possible
by adding a relief valve for very low and low speed
range operation. As a result, the damping force

characteristics have become linear as shown below,
so that the vehicle provides better feeling when

it rolls and shows better responsiveness to the steer-
ing wheel operation.

Rear Suspension

The rear suspension is similar to that introduced
on the 1994

It is a new development in

multi-link design. By properly arranging the
al control arms and properly selecting their bushings

for well balanced rigidity, a best compromise
tween high-level directional stability and riding
fort has been realized in the suspension.

Rear Suspension

A high-mounted upper arm and a combination of

lower arm and trailing arm act like a double-wish-
bone configuration having a virtual kingpin axis.

This construction, like that of the front suspension,

provides the following features:

Small offset between the virtual kingpin axis

and wheel center provides better directional sta-
bility.

The high-mounted upper arm helps improve

the tire supporting rigidity and riding comfort.

Like a double-wishbone suspension, the
link suspension features small change in “cam-
ber to ground” at the time of a roll, which assures
better stability during cornering.

In addition, optimum arrangement of the individual

arms and proper selection of the individual bushings
for well balanced rigidity have provided the following
effects:

Changes in toe angle caused by the up and
down strokes of the suspension are properly
controlled for better stability during cornering.

Changes in toe angle caused by a lateral force
acting on the tire are properly controlled for
better stability during cornering.

Even under the effect of a rearward force on

the tire, the wheel alignment does not increase
the “toe-out” tendency. This helps retain the
straight-line motion of the vehicle.
