WRX STi 2006 update

Godfather" is in a constant state of visual flux. It
seems that not a year goes by without Subaru introducing
some styling and/or mechanical upgrades to its all-important
2006 is no different, with the biggest change being an
all-new nose section grafted onto the familiar boxy
There are small changes all around to the 2006 version.
Subtle changes to the side skirts, the rear bumper and the
wheel-and-tyre set-up, as well as the wheel arches, keep the
Impreza moving forward. In the STiís case, make that
The STi remains a triumph of engineering over style. Looked
at from a fashion salon perspective, itís almost an
Bulges, scoops, great wheel-arch blisters, side skirts and
aerodynamic appendages make for a professional wrestler of a
car, rather than a refined gymnast in the Porsche,
Lamborghini or Ferrari idiom.
And yet, amongst enthusiasts, those that keep score sheets
from the World Rally Championship, the Subaru is an object
d art, a thing of unbridled beauty.
But as they say in the junk ads, thatís not all. The best
thing about the 2006 STi is that it just got a whole lot
The increase from two-litres to 2,5-litres is a radical one.
The rest of the engine layout remains pretty much as is,
with a pair of cylinders located on either side of the
crankshaft, a hundred and eighty degrees apart.
The cylinder heads have dual camshafts and four valves for
each combustion chamber. And the turbocharger has been
revised to enable it to start boosting from just over 1500
Maximum power is produced at a lower 5600 rpm, while the
torque peak is quite high at 4000 rpm. Quite simply, the
power delivery has been transformed.
And importantly, the symmetrical all-wheel-drive system has
also been changed to cope with the extra power.
Apparently, Subaru feels that with all the extra torque, it
was prudent to feed more power to the front wheels and give
the car easier-to-handle understeer characteristics.
But make no mistake, if you climb on the throttle hard in
mid-corner, the rear end will step out, before the
anti-skid electronics step in to cool things down.
Itís, in fact, remarkable what the half-litre engine
capacity increase has done.
The rather off-beat boxer warble is still there, but in
The engine feels so much more refined, that at times you
feel you could be driving a six-cylinder.
And thereís a more gentle ramp-up to the fat part of the
power band, and thereís more of it.
The STi comes standard with Bridgestone Potenza semi slicks,
and the handling is now just about perfect for a road
The ride is firm, but not unduly so, and as with all Subarus,
thereís an immense feeling of mechanical strength.
The 0-100 time is not that much faster at 5,5 seconds, but
top is now a claimed 255 km/h.
A word of advice to owners attempting flat-out starts. Thereís
no wheel spin, thanks to all-wheel-drive. Now, with all that
extra torque, the clutch starts to smell after one or two
hard blast offs.
Thereís been another upgrade to the interior in terms of
panel finish and a few design tweaks.
You still wonít be buying a Scoobie for its interior as it
doesnít come close to the sophisticated German offerings
in this price bracket. But the suede Ėcovered rally seats
make up for that to some extent, as do the special gear knob
and the racy steering wheel.
