Efficiency graph

[GatorRiv]

I know the efficiency and range stats are a bit of a mystery. I wonder how many of below are known or strongly suspected

1. Is the remaining range impacted by your personal driving habits (ie. Average efficiency)? or battery health (ie, will the range decline over time)? Or is it only impacted by the drive mode you select? I presume temperature is not a factor although probably should be.

2. If you go to a trip meter and recompute your efficiency you will come up short of the presented efficiency. For me is is 2.38 vs 2.48. is this difference because the stated efficiency is attributing some energy usage to climate and accessories? Is it throwing out energy usage when in hold instead of drive (related to question #3)

3. On the efficiency graph on driver's screen, I presume it is 15 minutes left to right. I don't understand it given when I sit at a light for 5 mins it only slowly declines often still green instead of going to 0 as it should. It also seems each "point" isn't quite an instant efficiency measure but rather a few second average (at least when moving) other than when you are stopped. For a highly reactive instant efficiency view you can look to the graph to the right of the speedometer.

4. Lastly that range impact bar to the right of the chart. Sometimes the bar is fat, sometimes thin. Sometimes green, sometimes gray, sometimes blue. I presume this is a comparison of the 15 min average against something. Is it comparing against generic driver efficiency? Against my historic efficiency? I presume the thicker the more the delta against whatever it is comparing against. Even that is weird given it is sometimes (I think) a thick gray. No idea what that might be implying.....maybe wide swings on the 15 min chart but close to my average?

Thanks for any thoughts

I should have said my guess at Range Impact is narrow green means if15 min efficiency is maintained that you would get a few more miles that the range estimate. Thicker = more profound. Inverse for blue.

Still no guess at what thick gray means.

The best way to measure the efficiency on a trip is to use the figure in the trip meter. That will track your efficiency over the course of the trip when you reset it. The 15 min efficiency is more to help you drive more efficient.

I don't disagree but even that has some unexplained factors. Interested in some of peculiarities.

What I don't like about the trip graph is the line is pre-set and doesn't matter what driving mode you're in.

To me the rated range line should adjust based on driving mode. Like if I'm in conserve the "goal line" should be higher than if I'm in Sport.

I also don't like that its not adjustable.

I would love a trip graph like what Tesla has.

Ok, that nonsense just goes to show I was over thinking it. I'll just think of everything as somewhat informative but also error prone and not scientific

lol what

Mine's been doing that ever since the 46 update. Sometimes the Range Impact bar is almost full length up while the graph is below the line. Sometimes exactly the opposite, a gray bar almost full length down with the graph above the 2mi line. If there's a blue bar, I never see it.

Mine too....

I got in the vehicle yesterday evening after charging and the graph was almost flat-lined at the bottom and the green Range Impact was full length up and it read 20.3 mi/kWh Average. I should have taken a picture but was already late.

Pretty sure that's cheating... Can't figure out how though, but I'm pretty sure.

To point 3 if you haven’t moved then the efficiency won’t show that as it is energy per unit distance.

Yes it does, if you’re in drive and stopped at a light it will 100% go down. It doesn’t go down if you’re in park.

My guess was if you are in drive it counts but if it goes to hold it doesn't count. And park doesn't count either.

It counts when you're in the Hold position because you are still in Drive.
