Chassis dynamometer systems built for the next generation of vehicles
Chassis, hub and steerable dynamometers for EV, hybrid and ICE
Ascential builds chassis, hub and steerable dynamometers for teams validating EV, hybrid and internal-combustion powertrains. Powertrain and e-motor test benches deliver precise, repeatable results, built to your specification. Beginning in 1990, the EPA and CARB purchased Burke Porter dynamometers for emissions testing.
Cutting-edge testing that ensures EV efficiency & reliability
Our hub dyno enables a massive amount of testing variations for the electrical drivetrain of medium- to heavy-duty fleet vehicles. Featuring four wheel hubs, each linked to a shaft that is connected to an electric motor to provide resistance, it accurately simulates the road and eliminates inconsistencies.

Real-world testing precision for two-wheel drive vehicles
Ideal for light and medium two-wheel drive vehicles, this chassis dynamometer features a centrally mounted AC vector motor and roller assembly to simulate real road load and speed. It supports accurate emissions, performance, and fuel economy testing under true-to-road conditions.
Modular, flexible performance testing for dual-axle vehicles
Our four-wheel chassis dynamometer is modular, accommodating both two- and four-wheel drive vehicles. Each roller set is powered by digitally controlled AC vector motors for maximum precision and compliance.

chassis dynamometers (E-Dyno)
Purpose-built for electric and hybrid vehicle testing
The E-Dyno supports electric vehicles with 2WD, 4WD or AWD through closed-loop, independent roller control. Powered by Burke Porter's fourth-generation real-time control system, this setup delivers fast response and unmatched repeatability for EV testing.
Low-noise systems built for interior, exterior and vibration testing
Designed for semi-anechoic chambers, NVH dynos simulate real road surfaces using large rollers and replaceable surface spectra. They enable both interior and exterior sound, comfort and vibration testing across all drive types.

High-capacity inline dynos for commercial and industrial vehicles
These inline dynamometers handle loads from 1.5 to 60 tons and speeds of 150+ km/h. Perfect for buses, trucks and specialty vehicles, they support emissions, fuel economy and performance testing in demanding conditions.
Electromagnetic compatibility testing in darkrooms
Our 4x4, 6x4, and 6x6 EMC dynos integrate DC motors with precision control software for both static and dynamic EMC testing. Designed for darkrooms, they provide exacting response and test repeatability for multi-axle electric or hybrid vehicles.

and system equipment
Real-time power and performance control for every system
At the core of each Burke Porter chassis dynamometer is the D4 real-time controller. With integrated Windows 10 application software and advanced feedback processing, it delivers fast, accurate control across every test condition.
Who We Are
Long before the rubber meets the road, ahead of your vehicles even go into production, you need to be sure they will perform as intended. From safety to emissions, horsepower to power steering, and everything in between, you need to know that drivers and passengers can expect a superior driving experience that assures their wellbeing. At the same time, you need to be sure that your products can pass even the strictest regulatory standards. That’s why more manufacturers trust Burke Porter for laboratory testing than anyone else.
We’ve designed and installed hundreds of dynamometers and laboratory testing products worldwide, including multiple EPA and WLTP certified testing facilities. Count on our decades of experience with traditional combustion, electric, and hybrid vehicles to help you transition to the electric and digital age. At the same time, you can rely on our experts to help you reduce emissions and fuel consumption, enhance drivability, vehicle performance, and detection of defective emission control devices.
Unmatched regulatory expertise
Burke Porter’s experts know the specifications for passing regulatory tests better than anyone. We should, we helped write them. Our team actively contributes to shaping industry standards, ensuring our laboratory products not only meet but often exceed the strictest regulatory requirements.
