Turnkey Infrastructure Solutions
Building a complete vehicle test stand takes more than just the dynamometer itself. In fact, it also requires full infrastructure and seamless system integration — from foundations and test chambers to exhaust extraction, HVAC, power supply, and media lines.
With this in mind, our turnkey approach starts from day one. We work closely with you to define every technical and operational requirement. From there, we handle the entire process — from initial planning and engineering through full implementation — to deliver a fully functional, ready-to-use test environment.
From basement to roof, we manage every detail. As a result, your facility remains optimized, efficient, and built exactly to specification.
A high-performance dynamometer deserves an equally capable test environment. SEETECH delivers full turnkey test cells, including:
- Foundation engineering for high-mass roller systems
- Modular industrial soundproof rooms (up to 40 dB noise reduction)
- Exhaust extraction and HVAC systems
- Operator stations and safety interlocks
- Fully compliant with international EOL quality and safety regulations
Optional Capabilities for Motor Companies

Modular Industrial Soundproof Room
This high-performance soundproof room features a durable I-steel welded frame with beams and columns for maximum strength. We build the walls with custom acoustic panels. Steel pipes inside add stability. In addition, the corners are edge-wrapped for a clean, professional finish.
The wall system includes:
- Exterior: composite steel cladding
- Interior: sound-insulated color steel panels
- Mineral wool core: for superior sound absorption (≥80%), with leak-proof fiber layer
- Certified noise reduction: up to 40 dB sound insulation
- Color: clean industrial white finish
Furthermore, the structure supports modular assembly and disassembly. The internal walls are lined with sound-absorbing materials, and the frame can hold additional equipment loads such as:
- Ventilation and exhaust fans
- Maintenance hoists
- Steel framing, air ducts, mirrors, and other accessories
Designed for demanding industrial environments. Therefore, this enclosure delivers robust construction, excellent acoustic performance, and the adaptability needed for a wide range of applications.
The RTX series operates as a standalone test bench or as part of a complete SEETECH end-of-line bay. The same vehicle that runs roll, brake and drivetrain validation on the dynamometer can move through chassis geometry on the HYDRA W15 wheel alignment machine, headlamp aiming on the DRAGON X15 headlamp aiming machine, and sensor validation on our end-of-line ADAS calibration system — all under one MES handshake, one VIN scan and one audit trail. One supplier from foundation engineering to final commissioning.

LET’S DISCUSS YOUR DYNAMOMETER PROJECT
Tell us about your vehicle testing requirements, production line, test cell or integration needs. SEETECH will help you define the right AWD or 2WD dynamometer solution.
1. What is the difference between an AWD dyno and a 2WD dynamometer?
An AWD dynamometer (all-wheel-drive dyno) measures vehicle performance by driving all four wheels simultaneously, making it ideal for cars and trucks with AWD or 4WD drivetrains. This setup allows accurate simulation of real-world load conditions for complex drivetrains.
A 2WD dynamometer drives only one axle — either the front or the rear — making it suitable for front-wheel-drive (FWD) or rear-wheel-drive (RWD) vehicles. While 2WD dynos are simpler and often less expensive, they cannot accurately test AWD systems without drivetrain modifications.
2. Can I test FWD or RWD vehicles on an AWD dyno?
Yes. Modern AWD dynamometers — especially linked roller systems like SEETECH’s — allow the operator to select FWD or RWD mode, disengaging the unused rollers. This ensures accurate measurement without unnecessary drivetrain strain. It is particularly useful for mixed production lines that test multiple drivetrain types on the same bench.
3. Why are fully linked rollers important for AWD testing?
In AWD vehicles, the front and rear axles are mechanically connected. If the rollers are not synchronized, even a small speed difference can cause drivetrain wind-up, leading to inaccurate results or mechanical damage. Fully linked rollers — either mechanically or electronically — ensure that all wheels rotate at exactly the same speed, which:
- Prevents unnecessary stress on the vehicle’s transmission
- Provides repeatable, precise measurements
- Simulates real driving conditions more accurately
4. What types of vehicles can be tested on an AWD or 2WD dynamometer?
SEETECH’s dynamometers are designed to handle almost any wheeled vehicle, including:
- Passenger cars (compact, sedan, hatchback)
- High-performance sports cars
- SUVs and crossovers
- Light commercial trucks and vans
- Heavy-duty trucks and buses
- Motorcycles and three-wheelers
Our custom engineering allows us to adapt roller size, load capacity, and control systems for unique applications, from small-displacement scooters to multi-axle heavy vehicles.
5. What measurement capabilities do chassis dynamometers offer?
A high-quality chassis dynamometer measures:
- Torque (Nm) and power (kW or hp) at the wheels
- Vehicle speed and roller RPM
- Drivetrain efficiency and losses
- Fuel consumption (when integrated with fuel measurement equipment)
- Emissions data (when connected to an emissions analyzer)
They can also simulate aerodynamic drag, road gradients, and rolling resistance, allowing engineers to test under real-world conditions without leaving the facility.
6. How accurate and repeatable are dynamometer measurements?
Accuracy depends on the quality of the equipment and calibration. SEETECH’s AWD and 2WD dynamometers use:
- Precision-ground steel rollers
- Linked control systems with real-time synchronization
- High-speed data acquisition (up to 10 Gbps)
- Automated calibration routines
This ensures measurement accuracy within ±1% or better, and results are highly repeatable between tests — even across different days or operators.
7. Do I need to prepare my vehicle before dyno testing?
Yes. Proper preparation ensures both safety and test accuracy. Before testing:
- Warm up the engine and drivetrain to normal operating temperature
- Check tire pressures and match them across axles
- Disable traction control and stability systems unless specifically testing them
- Ensure all fluids are at proper levels
- Remove loose items from the vehicle interior
- Secure the vehicle on the dyno using approved straps and wheel chocks
8. What can an AWD dyno do that a 2WD dyno cannot?
An AWD dynamometer can:
- Test full AWD drivetrain functionality under load
- Evaluate torque distribution between front and rear axles
- Test vehicles with variable AWD systems (e.g., electronically controlled couplings)
- Perform brake balance and ABS/ESC testing in AWD mode
- Simulate traction loss scenarios and power shifts between axles
These capabilities are essential for manufacturers of modern AWD and 4WD vehicles, where drivetrain control is integrated into vehicle safety and performance systems.
9. Why do some dynos make more noise than others?
Noise mainly comes from roller-to-tire contact and the dyno’s load absorption system (eddy currents, hydraulic brakes, or AC motors). High-grip roller surfaces provide better traction and prevent tire slip but can generate more noise, especially at high speeds. SEETECH uses precision-balanced rollers, optimized surface textures, and soundproof room options to minimize operational noise while maintaining measurement accuracy.
10. What types of test modes do dynos support?
Our dynamometers support multiple operating modes, including:
- Steady-state testing – Holding a constant speed or load for tuning and diagnostics
- Ramp runs – Gradually accelerating to measure power and torque curves
- Transient tests – Simulating real-world acceleration, braking, and load changes
- Drive-cycle simulations – Reproducing standard test cycles like WLTP, NEDC, or custom OEM cycles
- Custom programmable profiles – Fully configurable speed, load, and gradient patterns for specialized testing
