Performance testing for powertrains (GMP)
Measure and optimise the performance of your propulsion systems
The Emitech Group offers comprehensive performance testing for powertrains (thermal, hybrid and electric). These tests assess the fundamental technical characteristics of your powertrains under controlled and representative conditions, with a view to their development, validation or optimisation.

Why carry out performance testing?
Performance tests are used to :
- Determine torque and power curves as a function of speed and load.
- Evaluate the overall efficiency of the powertrain.
- Validate response times, stability and control precision.
- Compare different engine configurations.
- Optimise thermal and energy management strategies.
What types of powertrain are involved?
- Thermal powertrains (ICE-D/G, MHEV, e-fuels, H2, NH3): combustion engine + transmission (gearbox, clutch, etc.).
- Hybrid powertrains (HEV, PHEV): thermal engine + electric motor + electronic management.
- electric powertrains (BEV, FCEV): electric motor, inverter, gearbox, cooling.
Test methodology
1. Installation on dynamic test benches
- Full integration of powertrain on high-power benches.
- Instrumentation of key points: temperature, pressure, torque, speed, consumption.
- Possibility of integrating the cooling system and energy circuit (fuel or electricity).
2. Carrying out the tests
- Static characterization campaigns (measurement at constant load, step-by-step).
- Dynamic tests (load ramp-up, speed variation, cycle simulation).
- Efficiency measurements and full mapping (mechanical, thermal and electrical efficiency).
- Specific performance tests: energy recovery, torque response, gear shifting, etc.
3. Data acquisition and analysis
- Synchronous multi-channel recording (thermal, electrical, mechanical).
- Real-time analysis and advanced post-processing (Concerto, Matlab, Python).
- Provision of engine maps, point clouds, thermal and energy balances.
