After 27 months of research and development, our engineers in Jihlava, the industrial heart of Europe, have brought a true evolutionary innovation to the field of Automotive Metrology. It is a passive simulator that is directly attached to the drive hub of the system.

"We have achieved a real milestone in solving applications where it is absolutely critical to understand the behaviour of the drivetrain and transmission in the Automotive and Motorsport industries. The repeatability, accuracy and reproducibility of the data obtained in this industry has never been at such a maximum level as in the case of the W series", said František Humpolíček, ATX-dyno Technical Director & CTO.

"The vision leading up to the launch of the W series project and its successful completion was to develop metrology equipment that would completely change the way testers look at test benches and offer professionals possibilities that were previously only possible in their minds. By integrating know-how and maximum concentration of science, we have introduced a device for the most prestigious applications that is currently unrivalled", said Jakub Klobasa, ATX-dyno CEO.

The future belongs to ATX-dyno dynamometers. Expertise, precision workmanship and quality are the essential attributes of this rising star.

Modular system 

The modularity of the W series system is absolute. Configure your test bench directly according to your needs. You can stack 2WD and 4WD combinations and even work with different braking performances for each axle. This is particularly practical in cases of hybrid and e-motion technology. Thanks to an advanced artificial intelligence system, the individual modules are fully synchronised in basic tasks while also being able to perform individual tasks in more sophisticated tests.


Don't be disturbed

A critical limiter of precision testing is where torque is transferred from the vehicle being measured to the dynamometer. It is also a limiting factor in conventional vehicle testing, whether high-performance machines or off-road. In particular, insufficient frictional force between the tire and the steel cylinder is a problem, whether due to low normal force or tire friction coefficient. Other major impediments to precision testing are tire heating, tire inflation, dirt, deformation in the suspension, and tangential displacement of the contact patch position between acceleration and deceleration.

For the sake of completeness, the dissimilarity of the tyre rolling on the road and on the roller should be mentioned. There are indeed many reasons not to go back to the past but to move forward. None of these deteriorating effects exist with the W series and therefore do not call into question the accuracy of the measured data. You can then concentrate fully on your profession.


It is smart

The SW architecture, together with the control electronics and ECU of the W series dynamometers, is essential for the correct collection, evaluation and interpretation of the test data. There is no room for compromise here, so don't. The smart control system is ready to take your word for it. Dynamic and static modes provide all the necessary background for an individual approach to specific tests and assays, all with maximum simplicity and intuitiveness.


Refined to perfection

Perfection is in the details. The W-series dynamometers are perfect. We have left only the best in them. Everything is just where it should be. Affordable, within reach and exactly the design you expect. You'll never forget anything, everything is sensitively incorporated into the design as are the 3 sets of flanges, connecting shaft, safety control cover, handling frame, handles, inspection holes and more. External ducting can be connected to the cooling exhausts to heat the designated area with the heated air, or to take it outdoors, for example when working in a climate chamber.



Working in a test room? Or do you need to be mobile? Or do you not have the possibility to build a special workshop for DYNO? We are ready to fulfil all your ideas. The W-series dynamometers are adapted for any installation, either in a stable laboratory space or with preparation for storage in case of non-continuous use.
