Those who know Audi know quattro®. And
anybody who has driven with the permanent
all-wheel drive system from Audi never wants to
drive any other way. Why? Because hardly any
other drive system ensures that the engine power
is transferred so directly to the road.
The Audi RS 5 sees the first appearance of the
latest generation of the quattro permanent all-
wheel drive system from Audi. Its key component
is the entirely newly developed self-locking crown
gear centre differential which, thanks to its plate
sets, enables high locking factors to be achieved
for even better traction. In addition it has a
weight advantage over the previously used con-
struction method and requires less installation
space. The basic asymmetrical torque distribution
of 40:60 (front axle:rear axle) is maintained for
the benefit of the driving dynamics; if necessary
it is, however, possible to distribute a higher
share of the torque to the front or rear axle.
In conjunction with the electronic distribution
of torque selectively to each wheel, for the first
time driving forces are now also allocated to each
wheel as a function of the driving situation. The
special feature of this system is that the torque
is already distributed before unwanted wheel
spin occurs. This allows the generation of a yaw
torque that provides assistance during cornering.
This all ensures a precisely controllable and
sporty handling, as well as an improved level of
agility with outstanding traction.
The new quattro drive train with torque distrib-
uted selectively to each wheel can be optionally
enhanced with the sport differential for the rear
axle.

Of course, that was not good enough for us.
The new crown gear centre differential
is fitted with plate sets to enable higher
locking factors to be achieved. This
enables up to 85 % of the driving torque
to be distributed to the rear axle and up
to 70% to the front axle.

30
years of quattro®
In 1980 we created, with quattro®,
one of the best all-wheel drive systems in the world.

The quattro drive train in
the RS 5 represents the latest
generation of the permanent
all-wheel drive system from
Audi. It includes the newly
developed self-locking crown
gear centre differential and
enables the torque to be dis-
tributed selectively to all of the
wheels.
