Abstract The inertia weight and road load power absorption simulation are dependent on the weight of the vehicle, and table values based on the test weight are used. Data presented in this report indicate the effects on fuel economy of varying both inertia weight and road load power absorption simultaneously according to the requirements of the Federal Register. This report primarily deals with improvements in inertia weight simulation and its effect on the accuracy of fuel economy measurements. It is assumed that any improvement in the accuracy of measuring fuel economy levels will also improve the accuracy of exhaust emission measurements. The secondary objective is to examine alternative dynamometer configurations which can be used to achieve improved inertia weight simulation as well as to provide the expanded range of weights necessitated by the proposed regulations on light duty trucks.
