EPA is initiating rulemaking proceedings to upgrade certain aspects of the EPA/DOE Fuel Economy Information Program. This report provides technical input to those rulemaking proposals. The results of five surveys of consumers' opinions on fuel economy, and on various vintages of the fuel economy information program, are summarized. They indicate a general credibility problem with the current EPA fuel economy figures. Design parameter sensitivity algorithms are presented, and the need is established for their use in deriving fuel economy ratings for untested vehicles. Road adjustment factors developed from recent in-use fuel economy survey data are given for a number of different labeling strategies, and the strategies compared and contrasted. Results of a detailed analysis of the effects on label 'accuracy' of inclusion/exclusion of road adjustment factors and varying levels of vehicle-specificity in labeling are given. From this study, the incremental benefit of progressive levels of departure from the current (1981) model type labeling system can be estimated.
