Testing Services

OUTSOURCE THE TESTING, FOCUS ON THE RESULTS

With our test facilities in Graz and Friedrichshafen and our product range, we can offer testing services for complex and varied challenges in powertrain technology and energy systems.

Our Testing Center teams handle all demands from development to series validation – whether for conventional drive systems or your visionary ideas for the future.


Testing often needs to be carried out even though the necessary infrastructure does not exist or existing resources are in use. With our in-house testing systems, we offer an alternative solution. Our experienced staff take care of the required testing, including the associated logistics and data management, with a clear focus and dynamic flexibility. State-of-the-art testing technology enables functional testing using different approaches and methodologies for the entire range of development stages.


We work quickly and economically to develop unconventional solutions for you.
