Whether it’s a long journey or a short sprint, the
RS 5 sports suspension provides the Audi RS 5
with excellent roadholding and you with poise
and assurance. It combines precise steering re-
sponse, outstanding directional stability and a
high level of agility.
The front axle is a five-link layout. This enables
precise wheel control and, thanks to the virtual
steering axis, a very short lever arm to reduce the
effects of driving and interference forces.
The rear axle is a trapezoidal-link construction
with independent suspension and a flexibly
mounted subframe. All key components of the
RS 5 sports suspension are made of aluminium to
keep unsprung masses to a minimum. This allows
for sporty handling and improved roll perform-
ance.
Sports suspension plus with Dynamic Ride con-
trol DRC is available as an option for the RS 5.
This suspension technology hydraulically reduces
the pitch and body roll of the vehicle over the
transverse and longitudinal axes. The dampers
are diagonally positioned opposite each other
and are joined to each other by oil lines and by
a centre valve on each side. Should the dampers
be differently immersed, such as when cornering
quickly, the valves will then act on the oil flow to
the deflected wheel. They strengthen the support
there, thereby reducing the lateral inclination
and as such, improve the handling. The sports
suspension with Dynamic Ride Control DRC can
be set to three modes using Audi drive select: the
comfort mode ensures a smooth rolling motion,
the auto mode assists in creating an involved
style of driving and the dynamic mode delivers
the very highest in driving precision.
To fulfil the dynamic handling requirements of a
high-performance vehicle, the characteristics of
the springs and shock absorbers and the stiffness
of the tubular anti-roll bars have been adapted
especially for the Audi RS 5 in the course of
meticulous development work and numerous
test kilometres, including on the race track.
servotronic has also been given special new char-
acteristics as part of its adaptation for the RS 5.
The rack-and-pinion steering provides variable
amounts of steering assistance depending on
the vehicle’s speed. When parking, servotronic
provides high levels of assistance, enabling you
to steer with minimal effort. In contrast at high
speeds, the steering responds with a high degree
of precision. The steering gear is positioned low
down, enabling a short route to be used to trans-
fer the steering forces to the wheels via the track
rods. The result is spontaneous steering response
and precise feedback from the road.

The sports suspension plus with
Dynamic Ride Control DRC
is based
on the RS5 sports suspension. The
vehicle’s pitch and body roll are
reduced by the hydraulic connec-
tion of the shock absorbers, which
are positioned diagonally opposite
one another, which in turn improves
handling. The operating character-
istics can be set to three different
modes: comfort, auto and dynamic.
