    This paper focuses on fuel economy and acceleration performance of vehicle using powertrain dynamometer with road load simulator. The engine and transmission are equally controlled to vehicle by configuration which is equipped with real engine, real transmission with torque convertor and throttle actuator and so on. It is easy to find the effect of road load and shift pattern of auto transmission on powertrain dynamometer by eliminating driver variables of vehicle and real road. All of boundary conditions except road load or shift pattern is surely kept to analyze clearly the effect of road load or shift pattern. After testing, it is possible to easily compare results of fuel economy and acceleration performance with all kinds of combinations. This test method which uses powertrain dynamometer is allowed to shorten the development time without vehicles.
