Flat-Trac Dynamometer Roadway

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.
