They presented their results in a paper at SAE 2014 World Congress in Detroit. In addition, two minivans were subjected to coastdowns to examine the similarity in derived coefficients for two duplicate vehicles of the same model. l/100 km) at 60 mph (97 km/h) to 33 mpg (7.1 l/100 km) at 60 mph to 22.9 l/100km); and.

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

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].
