EPA Road Load Force
here's a link to an online publication from the EPA to auto manufacturers.
The last page shows 3-cars,each a little different,and the coastdown time and road load hp @ 50-mph for each

PS It's interesting to ponder a 707-hp vehicle which might only need 14-hp to cruise at 50-mph.
