I found the wikipedia entry the easiest to follow:
https://en.wikipedia.org/wiki/Fuel_economy_in_automobiles
here are some others:
https://www.fueleconomy.gov/feg/fe_test_schedules.shtml
http://www.epa.gov/nvfel/testing/dynamometer.htm
Thanks.
I looked at one time and never found the WIKI. The Test schedules was informative.
You're right. WIKI was definitely easiest to follow. (And that was none to clear.)
So it looks like only one vehicle really needs to be tested and it may be very difficult on a manual trans vehicle.
It doesn't appear to specify who's lab and dyno need to be used for the test runs.
