28 quattro®
Those who know Audi know quattro. And once
you have driven with the permanent all-wheel
drive from Audi, you won’t want to drive with
anything else. Why? Because there is almost no
other
drive system around that transfers
engine
power to the road so directly.
The central component of the quattro drivetrain
on the Audi RS 6 Avant is the self-locking centre
differential. With its consistent lightweight
construction, a weight advantage has been
achieved over the previous version. The purely
mechanical planetary transmission distributes the
drive torques asymmetrically between the front
and rear axle in a 40 : 60 ratio for better driving
dynamics in the basic design. But if necessary up
to 70 % can be distributed to the front or up to
85 % to the rear to offset any occurring wheel slip.
In conjunction with the wheel-selective torque
control, the drive force is distributed to each
individual wheel according to the driving
situation. What is special here is the way the
effects of the torque distribution are felt before
undesirable wheel slip occurs. This allows a
yaw moment to be produced, which supports
cornering.
The result is precisely controlled and sporty
handling with increased agility and superb
traction at the same time.
On request the quattro drivetrain can be fitted
with sport differential on the rear axle, in order
to further enhance driving dynamics.
Why only use two wheels
when a car has four?

The self-locking centre
differential distributes the
drive force between front and
rear axle purely mechanically;
up to 70 % to the front axle
or up to 85 % to the rear axle,
as required
