You cannot ignore the other stuff as they have a demonstrable effect. Just ask any one who has run into unexpected headwinds that tanked their efficiency and range. Air density is a real factor, as are road conditions. They aren't negligible.

E = (F_drag + F_rolling + F_wind) * d + mgh, where:

E: is the total energy required
F_drag: is the aerodynamic drag force, calculated as: 0.5 * air density * drag coefficient * frontal area * velocity^2
F_rolling: is the rolling resistance force, calculated as: rolling resistance coefficient * vehicle weight
F_wind: is the force due to wind, calculated based on wind speed and vehicle velocity
d: is the distance traveled
m: is the vehicle mass
g: is the acceleration due to gravity
h: is the change in height

Awesome. What's your point? All we want is live data showing the kW power consumption/regeneration as we drive.

There's a phrase out there that says "Don't yuck other people's yum." It means don't crap on what other people are finding neat and interesting and fun. Telling us that knowing our instantaneous kW draw/regen doesn't really matter is definitely shitting on our enjoyment of the car.

We know the data is there. We know that other car manufacturers are able to show it. We even know that Ford can choose to show it in other models (including current ones like the Lightning F-150). We're just annoyed we don't have it for our car, at least not without some workarounds.

IT DOESNT MATTER. Let's pretend drag and friction don't exist - your car will use a predictable amount of energy to move from point a to point b with a change in height. How you do this DOES NOT MATTER (except more speed increased drag and certainly does matter in real life).

An analogy for you, moving your car from point a to point b over change in height, lets pretend this amount is a soda. lets pretend drag doesn't exist, how fast or how slow you drink the soda doesn't matter, the same amount of soda will be expended both ways.
It may not matter to you but it does to many of us. If you're not interested maybe you should go back where you came from.

I know I am jumping in on an old thread here but did this ever get resolved? I'm using CarScanner to show power to the primary motor, and it goes negative when the wheels are charging the battery. Is there a value in CarScanner that shows that power per the speed you're travelling? I turned on all the fuel related things and "EV Instant Energy Consumption [kWh/100km]" but they recored all zeros on the way to work today.
