Hybrid and Engine Testing

Modular test system design for development tasks of today and the future.
TC Stuttgart

Our hybrid and engine test systems (TS) are highly flexible development environments. These test systems provide precise test and measurement systems with high reproducibility for testing internal combustion engines and their hybrid components. For hybrid engine development, the systems use battery emulators to act as electric power sources or sinks, ensuring highly realistic battery behavior emulation on the testbed. Dedicated fuel supply installations, including conditioning and consumption measurement, support multi-fuel testbed operation.

Engine testing has a legacy of more than 70 years at AVL. This broad expertise has been demonstrated in thousands of engine testbed installations. On top of that, our propulsion system engineering team operates ICE and hybrid testbeds in tech centers around the world. Which is why our engine testing technology is continuously advanced by dedicated in-house expertise.

Engine Testing

Our portfolio of engine test systems is available for a wide range of research and development tasks.

These include:

  • Hardware verification 
  • System integration incl. hybrid components
  • ECU / HCU calibration
  • Hybrid operating strategy implementation
  • Fuel consumption optimization
  • Electric charge determination
  • Steady state and dynamic duty tests
  • Engine response optimization
  • Exhaust emissions development and homologation

Visiolution with AVL X-ion™
Visiolution AVL X-ion

Visualize the combustion process with our optical measurement equipment integrated into the AVL X-ion data acquisition platform.


AVL EPOS™ is our solution to these challenges. It allows you to manage costs, availability, and performance and make the most of your investment. 

Data Acquisition - AVL FEM 4

New powertrain technologies require a higher data throughput rate in real time. AVL FEM 4™ enables you to measure all raw data relevant for the characterization of the unit-under-test.

Angle Encoder
Angle Encoder 366C

Engine tests are now even expanding to vehicle testing on the road (RDE). AVL has developed a new optical encoder 366C that is much smaller, lighter and has less inertia than its predecessor. 


Portable on-board soot and PM measurement device.

AVL Opacimeter

The new standard for transient soot measurement in the exhaust gas of combustion engines as emission legislation and market requirements become more demanding.

Efficient testbed utilization is ensured by continuous improvements suggested by our in-house engineers. Our expert teams from Powertrain Engineering and Test System development are working closely together at all times. Effective and efficient development work is ensured by the holistic and seamlessly integrated our product portfolio, in which AVL hybrid and engine test systems play an important role. We support development from initial concept ideas to production. Individual development steps are integrated and connected via consistent development methodology tools.

In addition, our competent test application support is available to all our customers. Engineers guide our customers globally with firsthand expertise in tackling complex development tasks and challenges. The interaction of complex test system configurations can be verified prior to delivery using our advanced in-house system integration test environments (test center) to assure a right-first-time approach. Highly realistic test conditions are applied in combination with AVL simulation models (e.g. engines, dynos, measuring devices, etc.).
