Apply driver and longitudinal inputs within a repeatable and controlled environment to evaluate the efficiency, performance and durability characteristics of a vehicle drive train while operating on a straight, smooth road. Data generated by this system can be used for meeting WLTP (Worldwide-harmonized Light Vehicle Test Procedures) requirements as well as powertrain tuning for traditional ICE or EV applications.
MTS Flat-Trac moving belt technology accommodates spinning tires to create a high-fidelity, real-world vehicle-to-road interface.
Provides the vehicle-to-road interface accuracy needed to discern extremely fine changes in rolling loss from one design iteration to the next
Far more accommodating of high-throughput testing requirements than conventional roller dyno solutions
Accommodates any vehicle by varying track width, wheelbase, type of positioning, power density and bearing type
