Automotive fuel economy was the topic of a study during which technical and background information was gathered, curriculum materials were sought, and curricula were developed. Technical information came from written materials and actual mileage tests of selected factors. Background came from written materials, field trips, and building and running of project cars in fuel economy tests. While a great deal of technical information exists on fuel economy, no curriculum materials could be found, despite intensive search. Hence, materials were developed at four levels: (1) a one-hour presentation for general audiences; (2) a three-contact-hour general presentation for use in a basic automotive mechanics course; (3) a three-contact-hour specific presentation on fuel economy testing for a "gasoline engine technology" course; and (4) a three-credit course on fuel economy testing to be used as an in-service program for teachers on the secondary and postsecondary levels. (Basic curriculum materials, mileage test forms, and test results are appended.) (CP)
