The 4G15-MIVEC-T/C engine employed in the Colt
is designed to provide higher performance and
higher output by using a turbocharger to the
4G15-MIVEC engine employed in the conventional
Colt. The main changes in the conventional
4G15-MIVEC engine are as follows:•Cylinder head gasket changed
•Oil jet added
•Strength improved in piston and piston pin

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>
