TESTING SUPPORT FOR EVALUATION OF INSPECTION/MAINTENANCE ISSUES, TEST GROUP NO. 11

The intention of this test group was to investigate several vehicle types for possible shortfalls between their EPA certification test fuel economy levels and their in-use fuel economy as measured by the same test. Twenty different types of vehicles were evaluated with a total of 129 vehicles being tested. The vehicles were model years 1978-1980 and were recruited from the Portland, Oregon tri-county area.
