The EPA is considering developing procedures for manufacturer-specific adjustment factors for EPA fuel economy labeling: both vehicle design adjustment factors as well as in-use road adjustment factors. These procedures could be followed by a manufacturer if it feels that the adjustment factors provided by EPA regulations are not appropriate for its own vehicles. This report addresses the question of automotive vehicle fuel economy as influenced by selected vehicle design parameters and by conditions which differentiate the on-road environment from the test environment. The central thrust of the report is the formulation of applicable fuel-economy adjustment factors in the context of a specific manufacturer's product line.
