Drivetrain testing from every angle — system-level and component-deep

At ATESTEO North America, we test complete drivetrain systems as well as individual components, including electric axles, transmissions, gearboxes, and hybrid modules. We simulate both real-world and accelerated load conditions for hybrid, and electric vehicles. We also support drivetrain innovation beyond passenger cars, from micromobility to heavy-duty and aerospace applications.

Our engineers focus on performance, energy flow, durability, thermal behavior, and the interaction of mechanical and electronic subsystems under dynamic stress. That’s how we ensure your drivetrain meets performance targets, validation goals, and quality expectations.

Endurance testing.

Where long-term performance gets real.

Endurance testing focuses on how drivetrain systems behave over time under mechanical, thermal, and dynamic stress. We simulate real-world load cycles and operating conditions over extended durations to uncover wear patterns, thermal effects, and failure points before they impact your product.

Whether it’s gearboxes, e-axles, or complete systems, our endurance testing helps validate durability, safety, and system behavior across the full product lifecycle.

We apply both static and dynamic loads across full duty cycles, including start-up, acceleration, deceleration, shifting, and coast-down phases.

Depending on your goals and component type, the test durations vary but range from 100 to over 1,500 hours — with flexible bench configurations.

We support manual, automatic, hybrid, and electric drivetrains across front-, rear-, and all-wheel-drive platforms. Testing is available for a wide range of applications, from micromobility and passenger cars to heavy-duty vehicles and rail systems.

We capture torque, vibration, temperature, pressure, rotational speed, and wear indicators — with continuous data logging and test automation.

Efficiency testing.

Where energy loss becomes engineering insight.

Efficiency testing reveals how effectively a drivetrain converts energy into motion. We measure and analyze power losses, frictional behavior, thermal influences, and mechanical resistance under defined operating conditions.

Our engineers help optimize fuel consumption, electric range, and energy flow across hybrid and electric systems. The result: lower losses, better performance, and measurable gains in drivetrain efficiency.

We measure input and output torque, speed, power, temperature, and rotational resistance to evaluate system-level efficiency.

We support testing for transmissions, gearboxes, e-axles, hybrid modules, and complete drivetrains across all propulsion types.

Real-time measurement tools with high sampling rates and integrated automation ensure repeatable, high-resolution test results.

Yes. Our testing benches can replicate customer-specific driving cycles and regulatory test procedures to assess efficiency under simulated conditions.

Functional testing.

Where drivetrain behavior becomes measurable.

Functional testing evaluates how drivetrain systems respond to changing load, speed, and shift conditions. We simulate dynamic scenarios and monitor the interaction of mechanical, electrical, and software-based subsystems.

Our testing covers transmission response, control strategies, torque path behavior, and driveability — helping you tune performance and identify critical interactions across all drivetrain architectures.

We analyze shift quality, torque buildup and transfer, synchronization, clutch behavior, and control system responses under dynamic loads.

Testing is available for automatic, dual-clutch, hybrid, and electric drivetrains, as well as manual transmissions and multi-speed gearboxes.

Yes. Functional tests often include validation of TCU logic, actuator timing, and calibration of control parameters in real-world conditions.

Automated sequences enable repeatable testing of complex load and shift patterns, reducing variability and speeding up validation.

Environmental simulation.

Where drivetrains face reality.

Environmental simulation testing exposes drivetrains to temperature, humidity, altitude, and pressure conditions they may face in real operation.

We replicate extreme climates and stress factors to identify how components behave under environmental load. This enables you to validate functionality, material performance, and system integrity across all operating conditions — from cold starts to desert heat.

We can test from -40 °C to +150 °C, with variable humidity levels, altitude simulations, static or dynamic.

Complete drivetrains, electric axles, gearboxes, and cooling systems are tested as assembled units or in modular setups.

Yes. We simulate real-world environments for drivetrains used in micromobility, passenger cars, commercial vehicles, heavy-duty platforms, and rail systems.

We monitor temperature distribution, material expansion, vibration, leakage, system activation times, and performance drift under thermal load.

Yes. Environmental chambers are integrated into endurance and functional test benches, allowing combined load and climate testing.

E-mobility testing.

Where electrified drivetrains prove their power.

E-mobility testing at ATESTEO covers the full range of electrified drivetrain systems — from single inverters to integrated e-axles and multi-motor setups. We validate thermal behavior, torque delivery, energy flow, recuperation, and system response under high-voltage and dynamic load conditions.

Whether you’re working on a lightweight EV or a heavy-duty electric platform, we provide the precision and insight you need to optimize electric performance.

We test inverters, e-axles, e-machines, reduction gears, differential systems, and integrated electric drive units — individually or in combination.

We measure electrical efficiency, torque, temperature, voltage stability, vibration, and thermal characteristics under simulated drive cycles.

We support testing for drivetrain systems from two-wheelers, passenger cars, commercial EVs, and electric special-purpose vehicles — including high-voltage systems above 800 V.

Yes. Our test benches simulate deceleration and energy recovery scenarios, as well as customer-specific or regulatory driving profiles.
