Advantages of the all-w
The Audi 100 quattro all-wheel drive
system has the following advantages
over a two-wheel drive vehicle:
Driving Power
Driving Power is greatly increased by the
continual all-w
snow and slippery surfaces, when
starting off from a standstill, and when
driving on rough roads.
Within reason, y
go places where other vehicles may
likely get stuck. It is easier to stop on
slippery hills and get going again.
Moving Force
As the driv
goes to four wheels instead of two, the
amount of
This improves the traction between tire
and road surface and thereby, the drive-
ability on slippery road surfaces.
On vehicles with two-w
By distributing the dri
instead of two wheels, the
Audi 100 quattro are less likely to spin
under the same conditions.
Tire wear
Since engine power is transmitted to four
instead of two wheels, the slip at the
wheels and tire wear is automatically
reduced. On the Audi 100 quattro. the
service life of the tires is therefore better
than that of the driving wheels of a simi-
larly powered two wheel drive vehicle,
providing the same driving style is ap-
plied.
Snow tires
With the all-wheel drive system the Audi
100 quattro is good for winter driving
even with standard tires. However, we
recommend the use of all season tires or
radial snow tires (M+S) with or without
studs

Snow chains can improve both road
traction and braking when driving in se-
vere winter weather. Therefore, use
snow chains on your all-wheel drive vehi-
cle when required. For additional infor-
mation, see page 126.
Operation
In contrast to conv
systems that require transmissions to be
manually engaged when needed, the
Audi 100 quattro has no selector controls
that have to be operated by the driver.
