News: We road test Mitsubishi's banzai Evo IX right here. Check out what Feann Torr thought of the car after hammering it for a full week through the Australian alps. For more than a decade Mitsubishi's rally-bred Evolution
cars have been scaring drivers witless with their stupefying
grip levels, balanced chassis dynamics and stomach-wrenching
levels of acceleration.
The basic recipe for Evo success involves a stiff and durable
chassis, a small footprint for rapid turn-in and a banzai
turbo motor hooked up to an AWD transmission.
Et voila - viva la Evolution!
In 1992, the original Evo made a cautious debut, and now,
more than a decade later, the new Evolution IX (Evo 9) has
hit the domestic market in Japan, creating the next chapter
in the history of Mitsubishi's almost-mythical hero car.
Mitsubishi's ninth Lancer Evolution takes the story to a
new place, not so much in terms of appearance, but certainly
performance.
As you can see from the photos, it doesn't appear as though
the new Evolution's sheet metal has been altered greatly,
though the die-hard Evo aficionados are sure to pick up on
some the nuances here and there, such as the small fog lights
up front and the disappearance of Olivier Boulay's bold triangle
in the grille.
One of the most obvious visual changes to the giant-killing
turbocharged small car is at the rear, where a race car inspired
diffuser adds contrast to the colour scheme (unless you buy
a black one), while at the same time reducing the turbulence
in the airflow underneath the car for better high speed stability.
Mitsubishi made the subtle changes to the exterior of the
car to better reflect the current WRC Rally car, with the
abovementioned fog lights located either side of the front-mount
intercooler forming part of the new front bumper section.
This front end may may look similar to the Evo VIII, but
in fact is all new and includes a number of changes to improve
performance.
The lower air dam's opening has been increased to "raise
engine cooling efficiency" by providing the intercooler
with greater volumes of air, and in Japan you can even specify
your brand-spanking Evo IX with an air dam extension and rear
wing Gurney flap that help to improve the Mitsubishi's aerodynamics.
New-look alloy wheels also form part of the Evo IX's exterior
upgrade, and inside the car things have been tizzied up as
well, but like the exterior the alterations are not exactly
what you'd call dramatic and most people probably won't care,
with the changes limited to the dashboard finish and the accelerator,
brake and clutch pedals, while better acoustic damping works
its magic unseen.
Having driven an Evo
VI TME and an Evo
VIII, it must be said that their flamboyant appearances
certainly do garner a bit of attention on the road, but of
far more import to most enthusiastic drivers as well as for
me is the way in which these turbocharged cars go about their
business.
And in 2005, we can expect even more fireworks.
Perhaps the biggest new feature to the Evolution's 1997cc
powerplant is the adoption of variable valve timing on the
intake system, or MIVEC as the Japanese car maker calls it
(Mitsubishi Innovative Valve timing Electronic Control system).
The MIVEC system helps the 16-valve 4G63 engine liberate
more power at higher revs and more torque at lower revs, with
peak torque of 400Nm @ 3000rpm and maximum power of 206kW
(280hp) @ 6500rpm.
Mitsubishi also made changes to the exhaust-gas driven turbocharger
"that result in higher torque and produce better response
for improved engine performance across its full rev range"
to use Mitsubishi's own words.
Such increased engine performance puts the 0-100km/h sprint
time at 5.9 seconds according to the Japanese figures, with
top speed at just over 230km/h.
In Japan, the Evolution IX is offered in three trim levels,
with the GSR benefiting from all of Mitsubishi's rally-derived
gadgets for the ultimate road-going ride, giving drivers grip
and handling levels that would make Lamborghini Gallardo owners
take notice.
The GSR gets ACD (Active Center Differential),
Super AYC (Active Yaw Control), customised
ABS (Sport ABS braking) and an electronically
controlled all-wheel control component system, not to mention
a 6-speed manual gearbox.
Next up is the RS, the motorsport model that was created
to cater for the rally motorsport market, which incorporates
a lighter body, a new titanium-magnesium turbocharger compressor
wheel (instead of aluminium alloy), a 5-speed close ratio
gearbox plus ACD and a mechanical rear LSD all-wheel control.
It tips the scales at just 1320kg, lighter than the GSR and
GT, weighing 1410kg and 1390kg respectively.
The third model is the GT, a new model for the Evolution
series, which features the best of the GSR and RS models,
which "brings together RS's turbocharger and drivetrain
specification and GSR's comfort-bias body with its enhanced
sound deadening," according to Mitsubishi. As a result
of the lighter turbo compressor wheel, the RS and GT models
make 407Nm @ 3000rpm, up 7Nm on the GSR model.
All Mitsubishi Evolution IX models feature new rear springs
that reduce the vehicle's height somewhat, a move that the
Japanese automaker says improves rear end stability in the
RS and GT models and for the GSR enables the Super AYC to
work a little more effectively at high cornering speeds.
The aluminium roof panel first seen on the Evolution VIII
MR model has been fitted to all models for 2005, and other
features include freshly tuned Bilstein shockers in addition
to big Brembo brakes on the on GSR and GT models.
Whether Australian-specification Evolution IX models pack
the full 400Nm, 206kW experience remains to be seen, and particularly
when Japan has higher quality fuel on offer (meaning de-tuning
to suit local fuel grades), but the new Evolution IX is without
doubt one of the most powerful cars Mitsubishi has ever released.
And let's not forget about the Evo IX's contemporary new
look either, with the aggressive rear end and new look front
combining to create an even more athletic and appealing image
than before. Going up against Subaru's perennially popular
WRX STi will be no cake walk, but the new 2005 Evolution IX
is packing more power and more features than before, and you
can be sure we'll be on the blower to Mitsubishi booking our
test drive in the new model when it arrives Down Under later
in year, expected to be September or October.
Evolution Terminology:

ACD (Active Center Differential)
The ACD incorporates an electronically controlled hydraulic
multi-plate clutch. An ECU optimises clutch cover clamp
load for different driving conditions, regulating the
differential limiting action between free and locked
states.
Effect: The result is improved steering response
together with better traction. ACD provides three modes
-- Tarmac / Gravel / Snow -- to enable quicker control
response for changes in road surface. A single ECU provides
integrated management of both ACD and Super AYC components.

Super AYC (Active Yaw Control)
Mitsubishi's Active Yaw Control system uses a torque-transfer
mechanism in the rear differential. Under ECU control,
the system operates to raise cornering performance by
transferring torque between the rear wheels as dictated
by driving conditions and so control the yaw moment
acting on the car body. In an evolutionary step, switching
from the use of a bevel to a planetary gear differential
gave Super AYC the ability to transfer almost twice
the torque between the rear wheels.
Effect: As well as reducing understeer further,
it delivers LSD-level traction. The use of a single
ECU to integrally manage Super AYC with the ACD results
in a synergism that makes both components operate more
effectively than if they were under independent control.

Sport ABS braking
The system ECU uses information from a steering angle
sensor that detects steering inputs as well as from
lateral G and vehicle speed sensors to apportion pressure
to each of the four wheels independently.
Effect: The result is improved steering response
under braking. Mitsubishi's Electronic Brake Force Distribution
(EBD) system, integral with Sports ABS, optimises allocation
of braking force between the front and rear wheels.
Increasing the pressure applied to the rear wheels when
braking close to the limit, EBD reduces the load on
the front wheels to realise better anti-fade performance.
The system also compensates for changes in surface and
vehicle load conditions to ensure predictable and consistent
stopping performance at all times.
