30 Suspension
Whether on long journeys or quick trips,
the RS adaptive air suspension gives the
Audi RS 7 Sportback excellent road handling
while giving you poise. It combines precise
steering characteristics, outstanding grip and
high agility.
The front axle features a 5-link design, while the
rear axle follows the self-tracking trapezoidal
link principle. Many vehicle components are
made of aluminium to reduce weight and keep
the unsprung masses low.
The RS adaptive air suspension combines air
suspension with a variably adaptive damper
system. Sensors on the body and on the axles
monitor the current driving situation and
send
information to the system during the journey.
This suspension also allows for various trims on
the vehicle and simultaneously acts as a level
regulator so that driving features are not
compromised even with a heavy load.
The RS sport suspension plus with Dynamic
Ride Control (DRC) is available as an option. With
this suspension variant with steel springs and
shock absorbers with variable characteristics, the
nodding and pitching movements of the vehicle
around the lateral and longitudinal axes are
reduced purely by hydraulic means. The diagonal
dampers are connected to one another via oil
pipes and one central valve each. If the dampers
are immersed differently, for example during fast
cornering, the valves affect the oil flow on the
cushioned wheel. They increase support there,
thus reducing side tilt and enhancing driving
dynamics.
With Audi drive select you can select different
modes to adjust the damper properties of the
suspension and, in the case of RS adaptive air
suspension the trim of your vehicle. The damper
recognition however can be varied in three
stages: comfort, auto and dynamic. Depending
on the setting selected, both suspensions offer
a wide scope for any route and for your driving
style.
In order to do justice to the dynamic demands
made of a high-performance vehicle, the
characteristic curves of the springs and dampers,
as well as the rigidity of the tubular stabilisers,
have been developed and put through their paces
in an extensive series of tests, including some
conducted on racing tracks.
Equally, the electromechanical power steering
was given a specific characteristic curve as part
of its adaptation to the Audi RS 7 Sportback. It
works with variable steering support, depending
on the speed. Thanks to the low-position
configuration, the steering forces are conducted
just a short distance to the wheels, which
provides a spontaneous steering response and
gives you precise feedback from the road. Since
the steering requires almost no energy when
driving in a straight line, it also helps to reduce
fuel consumption.
The fuel consumption and CO₂ emission figures as well as the efficiency class can be found on page 56.
Dynamic. Sporty. Self-assured.
Your suspension shows plenty of character.
RS sport suspension plus with
Dynamic Ride Control (DRC)
Thanks to the hydraulic links
between the diagonal shock
absorbers, the nodding and pitching
movements of the vehicle are
reduced, leading to enhanced drive
dynamics. The damper recognition
can be varied in 3 stages via Audi
drive select: comfort, auto, dynamic.
