TARGETS OF DEVELOPMENT
M2000004001066
EXCEPT RALLIART Version-R
The New COLT featuring "exciting feeling and free-
dom" has been developed for realising "safety, run-
ning, quality" and "free-to-s elect enjoyment" as well
as "true convenience and economical efficiency."
That makes NEW COLT a new generation compact
car.
RALLIART Version-R
This "COLT RALLIART Version-R" has been devel-
oped as a hot version in which the Mitsubishi Motors'
concept "Sporty
−DNA" was further refined.
In the midst of this recent wave of the sport model
launches in the compact car class, COLT RALLIART
Version-R has acquired users of the competitors and
the younger generation, and has improved the over
-
all image of the COLT series by appealing to the
sport-oriented users as the only high-powered turbo
-
charger vehicle in the class.

•COLT has been equipped with the new 1,500 mL
aluminium die-cast engine (4A9-engine) for fur
-
ther refinements of comfort driving, excellent
power performance, fuel economy, and ecology
performance.

•The body and suspension of COLT RALLIART
Version-R have been thoroughly tuned to
increase the 4G1-engine output which enables
dynamic driving.
•The robust image suited for the dynamic driving
has been adopted for the appearance.

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).
•The suspension has been tuned to improve cor-
nering and stability at high speed. Version-R>
•A strut tower bar has been adopted to improve
the body rigidity.
•Electric power steering system has been
improved and EPS-ECU has been additionally
equipped with the return control logic, resulting in
superior steering wheel return control and better
steering feel equal to or better than that for other
models with hydraulic power steering.

<4A9>
The newly-developed 4A9 engine has been installed
to realise small-size, light-weight, high-performance,
and better fuel economy with the state-of-the-art
technologies such as the aluminium die-cast cylinder
block, direct attack driven-type DOHC MIVEC, timing
chain-type cam drive, and rear exhaust.

The A TF warme r (A TF cooler) is adop ted for the
mode ls with 4A9 en gine. (the A TF cooler incorporat
-
ing the radiator is no t adopted)
At the start of runn ing, the tempe rature of th e engine
coolant rises earlier tha n that of the AT F. The A TF
war mer ut ilizes this ch aracteristic to raise the ATF
tempe rature a s ea rly a s po ssible to an a ppropriate
leve l (70
−80 °C). It also co ntrols flu id tempera ture st
ably and reduces A TF agitation resist ance to
imp rove f uel consump tion ra tio.
In addition , a thermo-valve has bee n adopted to
restrict the eng ine coolant supply to the A TF warmer
(A TF coole r) until the engine co olant temperature
reach es th e appro priat e temperature when low tem
-
perature start in winter , giving the priority to th e heat-
ing performance .
