Complete Solutions for Advanced Drivetrain Development
Powertrain & Transmission Testing
Supporting All Powertrain Architectures
Our test cell solutions are designed to support the full range of powertrain configurations, including:
- Traditional combustion engine powertrains (FWD, RWD, AWD)
- Hybrid and plug-in hybrid electric vehicles (HEVs & PHEVs)
- Battery electric vehicles (BEVs)
- e-Axles and integrated drive units (IDUs)
- Multi-speed and single-speed transmissions
We work with OEMs, Tier 1 suppliers, and research organisations to deliver systems that simulate real-world conditions and drive performance at the highest level.
Capabilities Include
- High-precision dynamometers for engine, e-motor, and axle testing
- Road load simulation and environmental conditioning
- Gearbox and transmission test rigs with torque vectoring and efficiency measurement
- Battery simulation and inverter integration for hybrid and EV systems
- Automated test scheduling and data capture for repeatable results
- Thermal management systems for accurate cooling and lubrication control
Transmission Testing with Real-World Simulation
Our transmission test benches are engineered for durability, shift quality, efficiency, and NVH testing. We can replicate dynamic vehicle conditions, including gradients, torque demands, and acceleration profiles, using advanced real-time simulation platforms. Combined with flexible software control and robust safety systems, we provide a safe and realistic environment for pushing driveline components to their limits.
Customised Software and Automation
We supply every test cell with a tailored control and automation system, enabling real-time test management, remote access, and detailed data analytics. Whether integrating with existing facility software or providing a new interface, our automation systems are designed for ease of use, test efficiency, and scalability.
Hybrid and Electric Powertrain Integration
Our expertise extends to electrified powertrains, where testing requirements include the coordination of e-motors, batteries, inverters, and control units. We offer full hardware-in-the-loop (HiL) integration, enabling you to test powertrain systems in isolation or as part of the complete vehicle simulation – essential for developing next-generation EVs and hybrids.
Turnkey Test Cell Design and Delivery
From test bed concept and layout design to full mechanical, electrical, and software integration, we offer a complete turnkey service. Every Sierra CP test system is engineered for your specific use case, facility constraints, and performance targets — and delivered under one contract for simplicity and accountability.
