Saab
Handling
Introduction
Saabs have a reputation for handling:
understeer and brilliance in the
snow. The two are linked. This reputation has been carefully honed over
several generations of cars with one notable exception, the GM900 or 900NG
model. Indeed, of the many changes Saab
made to the GM900 to produce the 9-3, refining the chassis and suspension to
Saab-ify it features high up on the list.
Understeery
Handling?
As you can read here, understeer is a form of skid whereby
the car does not turn as tightly as the steered wheels wish it to. All cars will understeer, some will only
understeer under exceptional circumstances.
Many rear wheel drive cars will understeer at high speed and oversteer at lower speeds.
For Saabs, though, understeer has
become an art. However, it's not just
that the car understeers, it's how the car behaves when the driver attempts to
counter the understeer.
I remember my first drive in the
new 900 Turbo. Back in the day, one
hundred and fifty brake horsepower (or
just under) in the Saab was something to shout about. The 900 Turbo felt rapid. Throw the car into a corner at too high a
speed and the front would indeed wash out wide.
Lifting off would cause the nose to tuck in without so much of a jiggle
from the back. If you were going far too
fast, a quick dab on the brakes was enough to bring the nose back in line. All without any untoward moment from the back.
Saab engineered out lift off
oversteer, something I came to enjoy in the Ka.
In some respects, I miss the lift
off oversteer. Sure, it took practice, a
few half spins, some silly grins, but it was the lift off oversteer that made
the Ka such a hoot. Barrel into a
roundabout at speed, turn in, lift off for a moment then back on the power to
catch the tail. Not a recommended
roundabout technique but perfect for encouraging a tailgater to give you more
space...
Try the above in my 9-3 and when
you lift off, the nose tucks in and the understeer stops. The tail remains planted on the road. The Michelin Energy tyres I'm using as I
write this article do shriek their protest at hard cornering loads but it's
always the fronts that howl.
The
Snow
So, on normal roads, the Saab will
understeer and then stop understeering on demand. Hardly exciting stuff, really, but at least
it's predictable.
On the white stuff, the car
behaves the same way. Give it too much
power and it understeers. Shut down the
power mid way around a corner and... the understeer is reduced. If you're going fast enough it probably won't
stop understeering unless you reduce the steering input too.
