What does this indicator mean?

The solid blue eco bar is definitely not static. It grows and shrinks all the time.

For example, at steady highway speeds it’s longer, reaching out beyond the word “Eco”. Other times it’s shy of the “c”.

I have no idea why it changes length. Would love to find out.

Motor efficiency is a function of both torque and rpm.

I'm fairly sure that on my car the Eco section wasn't solid blue, but was instead white hash marks, and it didn't seem to grow or shrink during the 5 miles or so I used it. Interesting...

Steady power consumption.

Yes, that seems likely. That or power consumption below a certain threshold. Pirracas77, what mode were you in: D or D Eco? That may be the difference. I was in Drive - Eco.

Well, since it replaced the trees, I thought it worked the same but it didn't. Driving super slow with lots of regen, etc. didn't make the line grow but driving at a constant power (not constant speed) seemed to get the best results. Although I didn't try very hard; was wondering how big the line would get. It would seem it would cover the entire dial but I never saw it much farther than maybe 2-3 spaces past ECO (imagine ECO was a 5 or 6 letter word?) But driving at constant power for extended periods of time requires special circumstances that are just not all that common in my area. I was using B ECO most of the time because that is easiest mode to control power although I never tried E Pedal. Might be worth revisiting one of these days if I happen to be on a lonely road to somewhere?

D + ECO

Maybe the blue bar is indicating the same as this panel
