Our experience with NVH powertrain testbeds allows us to provide a high-quality acoustic test environment for e-axles. All components and acoustic enclosures are designed by us to ensure excellent NVH performance with minimal sound reflections through simulation-optimized design. The focus lies on easiest handling of the testbed component. Thanks to movable loading units, convenient adaptation to different test specimen sizes is possible. In addition, easy access to maintenance areas is ensured by hinged acoustic enclosures.
Highly Customizable
Standard and highly customizable testing solutions from single components to full vehicles.
One Look and Feel for All NVH Test Systems
Continuous improvements focused on easy handling and a minimal acoustic footprint are the main targets of the design.
Outstanding Acoustic Performance
The well-developed driveline for NVH e-axle testbeds guarantees lowest noise levels in operation to reach a high SNR (signal to noise ratio) for acoustic measurements.
NVH Expertise
Experienced NVH experts at AVL provide customer-orientated solutions for the complete NVH testing lab with multiple testbeds.
- The maximum rotational speed of 3,000 rpm allows to simulate and test highest vehicle speeds.
- The complete driveline including intermediate bearings and wall pass shafts is capable to transmit a constant torque of 10,000 Nm.
- The track width of the test setup can be continuously adjusted up to 600 mm for each side, 1,200 mm in total.
- The wheelbase can be adapted over a wide range, depending on the requirements.¹
- AVL commits to a maximum noise level of 55 dB(A) at a maximum speed of 3,000 rpm.
¹ Only for 4WD configurations.

Low Noise Intermediate Bearings
The load system’s intermediate bearings are specifically designed for NVH applications to ensure smooth operation with low noise and vibration levels. This ensures the best possible focus on the test object.
Infinitely Variable Adaption Systems
Both track width and wheelbase can be adjusted in infinitely variable increments. This ensures perfectly repeatable mounting conditions for the UUT.
Quick Setup Time for Reduce Down Time
In addition to the focus on NVH performance, great emphasis is placed on ease of use of the test system. This reduces testbeds downtime and optimizes productivity.
NVH is not only about improving noise on vehicles and powertrains, much more it’s about setting up a brand sound, inspiring the passengers of modern cars during their ride. With our NVH test systems and solutions we provide a high class development platform for sound development and drive the pleasure of tomorrow’s mobility.”

Unique NVH test environment offers wide variability in testing capabilities.
At AVL, we develop e-axle solutions that can be easily installed without impacting the productivity of your engineering facility.
AVL has a long tradition and great experience in NVH (Noise, Vibration, Harshness) powertrain development and vehicle sound design. For this reason, AVL has introduced a high-end NVH testbed for NVH testing ranging from components up to complete vehicle testing.
AVL has a wide portfolio consisting of dedicated e-motor test systems, software, tools, and processes to test and validate these modern e-drive systems in shortest time and with highest quality standards.
Electrified propulsion systems are a growing part of modern transportation. The changing noise/sound landscape is increasingly demanding modern NVH engineering. At AVL, we have solutions and processes for optimizing the design and quality assurance of interior and exterior vehicle sound.
AVL RACETECH, the motorsport department of AVL, presents the prototype of an innovative H2 internal combustion engine. The power unit is a compact, hydrogen-powered 2-liter turbo engine, with intelligent water injection, which achieves a totally new performance level. The first racing engine that AVL RACETECH is developing and building in-house.
