This assessment examines the costs and benefits of improving the fuel economy of passenger cars and light trucks for model years (MY) 2011- 2015. It includes a discussion of the technologies that can improve fuel economy, analysis of the potential impact on retail prices, safety, lifetime fuel savings and their value to consumers, and other societal benefits such as improved energy security and reduced emissions of pollutants and greenhouse gases1. In the previous rulemaking, the agency reformed the corporate average fuel economy (CAFE) standards for light trucks with a size-based standard based on footprint2. This rulemaking continues this approach for both passenger cars and light trucks. A continuous mathematical function provides a separate fuel economy target for each footprint. Different parameters for the continuous mathematical function are derived for each model year. Individual manufacturers will be required to comply with a single fuel economy level that is based on the distribution of its production among the footprints of its vehicles in each particular model year. Although the same reformed CAFE scheme is proposed for both passenger cars and light trucks, they are established with different continuous mathematical functions specific to their design capabilities.
