AERODYNAMIC PERFORMANCE
Deterioration of aerodynamic performance accompanied with enlargement of the body size has been
suppressed by attaching a large-sized under cover on the lower part of the engine compartment, optimizing
elevation angle setting of rear spoiler.
(1) Under cover
A large-sized under cover is designed for compatibility of reduction of air resistance and reduction
of lift.
(2) Rear spoiler
Lift control by attaching elevation angle adjustable rear spoiler and optimizing attached position of
the spoiler are designed for reduction of air resistance.

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.
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.
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.
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.

BRAKING SYSTEM
All models feature fade-resistant 14-inch ventilated
discs up front and rear 8-inch drums for sure, linear
stopping power.
A 4-sensor, 3-channel ABS (Anti-lock Braking
System) with EBD (Electronic Brake-force
Distribution) is available. ABS adjusts the braking
pressure of the front wheels independently and
rear wheels together for controlled emergency
braking.
New for the Lancer, EBD works with the ABS
computer to evenly modulate each channel’s
braking pressure for ideal braking force regardless
of load or surface conditions at all times.

PASSIVE SAFETY
SRS AIR BAGS
Dual SRS (Supplemental Restraint System) front
airbags deploy only upon detection of frontal impact.
When used in combination with the 3-point ELR
seatbelts, they significantly mitigate head and upper
torso injury to front-seat occupants.
Seat belt with pretensioner featured for the driver’s
and front passenger’s seats is designed for instantly
taking up the slack in the seat belt at the time
of impact to improve restraint effect on a passenger.
It is activated approximately at the same time as
SRS airbag is activated to improve protection effect
on a passenger.

BODY CONSTRUCTION
The EVOLUTION-VII safety-enhanced body
structure comprises front and rear crushable zones
that effectively absorb the impact energy of front
and rear collisions.
Adding to all-round occupant protection is a
deformation-resistant, highly rigid cabin structure
that features strategic reinforcements plus large
side-door impact bars.

SAFETY-ENHANCED FRONT SEATS
The front seats are designed to minimise the risk
of whiplash in a collision from the rear.
The headrestraints have been ideally angled
forward, while the seat frame was moved toward
the rear.
In-house tests show a roughly 40% improvement
in occupant injury figures.

IMMOBILIZER SYSTEM
This system lets the engine be started only when
an encrypted code that is recorded in the ignition
key is the same as an encrypted code that is

ENHANCED DIAGNOSIS SYSTEM
Diagnosis functions have been included for the
following systems, so that it is possible to use the
MUT-II to read the diagnosis codes and service
data and to carry out actuator tests. In addition,
it is also possible to read the diagnosis codes by
the flashing of the warning lamp in some systems.
