[Abstract] China's corporate average fuel consumption (CAFC) standards are curb weight based with discrete fuel consumption targets for different weight classes, which imposes significant impacts on the light-weighting stratery of automotive manufacturers. In this paper, the curb weight of all models in domestic passenger car market from 2010 to 2014 is investigated. And from the perspectives of brands, classes and curb weight changes, curb weight distribution of each weight subclass in CAFC standards is analyzed. Meanwhile, by employing cost-effectiveness analysis, the incentive for curb weight weight abnormal distribution is described. Our analysis indicates that automotive manufacturers manipulate curb weight of many models to comply with more favorable standards target. The discrete stepped characteristics of China' CAFC standards is not in favor of the application of light-weighting technologies.
