GENERAL - Technical Features
ENGINE
The turbo charger specifications have been
optimized by reducing the size of the turbine nozzle
diameter to increase the engine torque at
low- middle speed range as well as high speed
range.
TRANSMISSION
Implementation of fortifying each part to deal with
the increased engine torque and revision of the gear
ratio of the standard transmission are intended for
further improvement in power performance.
ALL-WHEEL INDEPENDENT SUSPENSIONS
While the popular and rally-proven McPherson strut
front and multi-link rear suspension systems have
basically been retained, they were optimized for
the new model.
The improvements to the front include adding a
crossmember brace to the lower arm mount for
more rigidity, flattening the chassis crossmember,
and realigning the roll center to an ideal height.
As a result, the suspension delivers enhanced
handling and straight-line stability, ride comfort,
grounding characteristics, and roll feel, as well as
less vibrations and noise.
Since adoption of magnesium diecasting rocker
cover and hollow camshaft is intended for light
weight of the upper part of the engine, vibration
of engine- transmission at acceleration can be
reduced to improve the response of the body.
The steering gear’s optimal position ensures
predictably linear toe-in changes.
Each arm of the rear multi-links with trailing arms,
as well as its linkage point and length, was
reevaluated to achieve optimal alignment.
Combined with the wider tracks, higher body rigidity,
and improved damping characteristics of the
bushings and bump rubbers, the suspensions
deliver a supple ride with superb handling stability
for relaxing, effortless control.

Distribution) is available. ABS adjusts the braking
pressure of the front wheels independently and
rear wheels together for controlled emergency
braking.

D To improve the reliability of cavitation at a high engine speed and to increase the amount of engine
coolant, output control system in which a thermostat is installed at the outlet of engine coolant from
the engine to the radiator has been adopted.
D To improve the engine cooling performance and save weight, a plastic tank and an aluminium radiator
fins have been introduced.
D The speed of electric cooling fan is optimally controlled by a radiator fan controller and the engine-ECU
according to driving conditions so that the fan operating noise is minimized and the fuel efficiency
is improved.

To complement the intercooler efficiency in ranges where the cooling efficiency of the air cooled intercooler
is insufficient, and attain high performance in various operating environments, a system which cools by
spraying water from a special washer tank for the intercooler to the front of the intercooler has been
adopted.
The features of the intercooler water spray system is as follows.
D Sprays water when the water spray switch on the floor console is operated.
D Adopts a system which enables switching between the auto mode which automatically sprays water
at the optimum operating conditions by signals from the ECU according to the engine state, and
the manual mode which is operated by the driver.
D Three water spray nozzles are located at optimum positions to enhance the intercooler efficiency.

D A main muffler incorporating a back pressure variable valve is adopted.
D Straight layout of exhaust piping has reduced vibration and exhaust pressure in exhaust system.
D The adoption of hanger rubber with lower spring constant and the decreased number of hangers
have reduced vibration in exhaust piping.
D The adoption of all stainless exhaust piping has enhanced resistance to corrosion and heat.

FUEL SYSTEM
The fuel system consists of parts such as electromagnetic-type fuel injectors, a delivery pipe and a fuel
pressure regulator. In addition, a fuel pressure control solenoid valve has been provided in order to maintain
idling stability after the engine is re-started when it is hot. This system is basically the same as the
previous system used in the 4G63-DOHC-Turbocharger engine for the EVOLUTION-VI.
