Newly developed H-shaped torsion beam type sus-
pension has been introduced.
•The coil spring is installed under the rear floor,
the torsion beam and arm assembly is installed in
front of the spare tyre house, and the shock
absorber is installed outside, so that the large
cabin space is achieved.
•The arm bushing with the toe control function is
adopted to optimise the tyre steering angle using
the bushing deflection caused by lateral force
and longitudinal force generated at cornering, so
that the good cornering performance is secured.
•The layout of shock absorber is optimised for
smooth riding.
•Long wheel stroke secures sufficient road holding
quality.
•The hub-integrated unit bearing is adopted for the
wheel bearing for sufficient suspension rigidity
(Refer to GROUP 27, Rear Axle
P.27-2).
•The dumping characteristic of shock absorber
has been changed. <4G1>
•The urethane bump stopper has been adopted to
improve the linearity. <4G1>
•Torsion beam rigidity has been improved <4G1>

3. The dash side brace has been manufactured as an unit in order to strengthen the joint between
the front sidemember and the front pillar, increas

ing the rigidity of the entire body.
4. The installation position of the steering gearbox has been lowered, and the sidemember from the
front to the rear has been straightened in order to
improve rigidity of the entire body.

ACTIVE DRIVING AND HIGH QUALITY
•For 4A9-engine, the aluminium die-cast cylinder
block has been installed for weight reduction of
the vehicle.
•For 4G1-engine, turbo-charger model has been
introduced to increase output and torque,
enhancing sporty image.
•Sporty driving has been ensured by the
"GETRAG" 5-speed manual transmission (floor
shift).
