Thanks, this example has helped me see the advantages to using Wh/mi. BTW - when I do route planning for my future Mustang Mach-E (it is on order), ABRP uses mi/kWh. Maybe that is because Ford uses it in the MME. You probably see Wh/mi when you use ABRP because that is what Tesla uses.For example if the rolling load is 80 Wh/mi and the drag load 150 but the latter increases to 165 if we speed up 10 mph it's pretty clear what is happening but to express the rolling load as 12.5 mi/kWh and the drag load as 6.6666 mi/kWh so that the total economy is 4.35 mi/kWh is, to my way of thinking much less clear.
Back to one of your previous posts, I understand why you say battery size is irrelevant, because really the rated range is only what is relevant. However, when we are trying to figure out what we think the highway range of the R1T will be, it is helpful to know the battery capacity because it allows you to get a better idea regarding the efficiency. One day, ONE DAY, Rivian will reveal enough detail so we will know, but for now, we can only guess. What does "400+" mean? 405? 425? I suspect closer to 405, but that is only a guess based on their previously reported battery size.
