This report examines the relationship among automotive fuel economy, ambient temperature, cold-start trip length, and drive-train component temperatures of four 1977 vehicles. Fuel economy, exhaust emission, and drive-train temperatures were measured at temperatures of 20F, 45F, 70F, and 100F using the 1975 Federal Test Procedure (75 FTP) and the EPA highway fuel economy test (HWFET).
