The National Highway Traffic Safety Administration (NHTSA) has taken a leading role in overseeing the rulemaking process for Corporate Average Fuel Economy (CAFE) standards. Argonne National Laboratory (ANL), a prominent U.S. Department of Energy (DOE) national laboratory, has developed Autonomie, a comprehensive full-vehicle simulation tool. Autonomie has established itself as an industry-standard tool for assessing vehicle performance, energy consumption, and technology effectiveness. Through an Inter Agency Agreement (IAA), the DOE Argonne Site Office (ASO) and Argonne National Laboratory (ANL) have been entrusted with the task of conducting full-vehicle simulations to support NHTSA's CAFE rulemaking initiatives. This paper introduces an innovative approach that relies on a large-scale simulation process. These simulations encompass standard regulatory driving cycles for various vehicle classes, spanning diverse timeframes.
