ORNL researchers quantify the effect of increasing highway speed on fuel economy

Green Car Congress

One tip is that drivers should obey the speed limit since the fuel economy of most vehicles decreases above 50 mph [80 km/h]. ORNL staff members John Thomas, Shean Huff and Brian West have worked to quantify this trend through analysis of dynamometer testing results for 74 vehicles at steady-state speeds from 50 to 80 mph [80 to 129 km/h].
