EPA paper on medium duty and heavy duty trucks.


Lots of amazing stuff in here including how a 2011 6.7 Ram cummins runs the EPA cycles with 50% payload added (page 106) then they go on to adjust many variables.

I love the graph that shows that a 50% decrease in fuel consumption leads to a 100% increase in fuel economy. Who would have thought?

... but from page 67 onwards it gets very noteworthy, describing the measured effect of several fuel saving technologies.

2011 Honda Insight + HID, LEDs, tiny PV panel, extra brake pad return springs, neutral wheel alignment, 44/42 PSI (air), PHEV light (inop), tightened wheel nut.
lifetime FE over 0.2 Gmeter or 0.13 Mmile.

For confirmation go to people just like you.
For education go to people unlike yourself.
