Innovative Chassis
Dyno Testing Solutions
for the Future of
Mobility
Chassis dyno testing systems are essential
for vehicle development and validation.
At AVL, AVL Zöllner GmbH is the company
in charge of this area. The company has
been part of the AVL Group since 2001 but
has been manufacturing sophisticated test
systems since the 1960s.
ith more than 1,400 installed systems, AVL Zöllner is
the undisputed market leader in chassis dyno testing
systems. Headquartered in Bensheim, Germany and
with a production facility in Hranice, Czech Republic, the com-
Tany reali^es amFitioYs veLicle develoTment and certification
projects around the world. It also has an impressive service
offering, which is fully integrated into the customer-focused,
global AVL service organization.
“In the past, emission legislation was the main driver of our
FYsiness. 8Lese days it is electrified and alternative drive
technologies that are placing new demands on development
and certification. ;e Lave aligned and develoTed accordingly
and offer state-of-the-art solutions,” explains Arnold Berger,
Managing Director of AVL Zöllner GmbH.
%n e\amTle oJ an innovative develoTment and certification
solYtion in tLe field oJ electromagnetic comTatiFility is
AVL ROADSIM™ EMC. The test system was developed
in collaboration with Rohde & Schwarz – the technology
leader in tLe field oJ )1' measYrement tecLnology Ɓ and is
characterized by fully integrated measurement technology.
With AVL ROADSIM™ NVH PREMIUM and AVL ROADSIM™
NVH COMPACT, the current program includes two NVH (noise,
vibration, harshness) testing solutions. All test systems comply
with current and future requirements – from mechatronics and
measurement technology to automation, methodology, and
automated lab management. “We are the benchmark in many
areas – for example, determining the range of electric cars.
This requires much higher accuracy these days than in the
past,” emphasizes Berger.
The innovation and quality of AVL Zöllner also appeal to
customers, as proven by the latest GEELY Quality Award.
AVL Zöllner kitted out the major customer’s climatic wind
tunnels with testbeds. This example also highlights the broad
spectrum of the portfolio – from two wheelers to passenger
cars and heavy-duty applications. A new system solution in the
latter area stands out: a one-of-its-kind regulation concept on
the global market for testing multi-axle vehicles, which covers
major future customer requirements in the HD segment.
The comprehensive portfolio meets the requirements of
established OEMs and new market players.
In the after sales area, the high number of installed chassis
dyno testing systems ensures stable growth: With new

AVL Zöllner’s testbeds are generally characterized by robust
mechanisms and a long lifetime, which is a major advantage in
terms of sustainability.
Another important success factor according to Berger is the
synergetic collaboration with a variety of AVL areas: “No one
else on the market can offer this extensive expertise.” The
exchange also results in hardware and software becoming
increasingly interlinked and optimally aligned for relevant
aTTlications. 8Le oYtcome Feing consideraFly LigLer Fenefits
