Endurance tests for powertrains (GMP)
Validate the long-term reliability and robustness of your powertrains
The Emitech Group offers endurance tests specifically designed for powertrains (thermal, hybrid or 100% electric). These tests are essential for assessing durability, detecting early faults and validating the performance of your propulsion systems under real or severe operating conditions.

Why carry out Powertrain endurance tests?
Endurance tests are used to :
- Check the mechanical, electrical and thermal performance of the powertrain.
- Identify performance degradation over time.
- Detect wear, fatigue or failure of critical components.
- Optimise energy management strategies (engine, battery, hybrids).
- Meet the requirements of manufacturers, equipment suppliers or regulations.
What types of powertrain are involved?
- Thermal powertrains: combustion engines (ICE-D/G, MHEV, e-fuels, H2, NH3), gearboxes, intake/exhaust systems.
- hybrid powertrains: thermal/electric integration (HEV, PHEV), energy management, conversion systems.
- electric powertrains: electric motors (BEV, FCEV), gearboxes, inverters, cooling systems.
Test methodology
1. Implementation on test benches
- Integration on high-power test benches with simulation of customer or standard cycles.
- Motorised load controlled to faithfully reproduce field stresses.
- Controlled temperature and humidity conditions (combined climatic tests possible).
2. Long-term cycling
- Simulation of several hundred or thousands of hours of operation.
- Alternating load phases (acceleration, braking, idling).
- Thermal cycles and repeated starts can be included.
3. Continuous data acquisition
- Real-time monitoring: temperature, torque, power, speed, vibrations, currents, voltages.
- Automatic alarms and shutdowns when faults are detected.
4. Intermediate inspection and post-test appraisal
- Planned shutdowns for partial or complete inspection of the powertrain.
- Dismantling and final inspection with metrological or destructive analyses.
