EV Mode: Separate ECO, Power, and Normal Modes?

I had gotten the impression that, like in HV mode, EV mode also has separate ECO, Power, and Normal sub-modes. Clearly the mode switch works in EV mode, and the displays show which you're in.

I just tried, in EV mode (with a full battery) coming to a stand-still on an open road and flooring it a few times, alternately in ECO and Power modes, comparing the apparent acceleration each time. I didn't "scientifically" time it, but just compared the subjective feeling of the acceleration. I only went up to about 35MPH or so.

I didn't really notice a whole lot of difference between Power and ECO modes under those circumstances. It was no Tesla by any means, but both modes were pretty darned quick accelerating, but not all that different, all in all. Maybe ECO mode is more economical in other ways; not sure...

What do you folks see along those lines?

 

In one of their videos, Toyota pointed out that the ECO vs. Normal vs. Power submodes and EV vs. HV are independent systems. (I can't remember their exact phraseology, but something close to that.) That and the fact that you can still select between the three modes, and that the displays indicate the three modes, at least implies that it does have the three submodes.

I think I recall that somebody here also reported that s/he got the impression that it did perform more powerfully in Power mode.

Yeah, me too.

Well, 99.99% of the time. Other than this experiment today, I have put it into Power mode twice to facilitate merging onto a freeway. That was just for a grand total of 8-10 seconds of driving time, though!

Kinda like y=x vs. y=x^2 vs. y=sqrt(x) curves. Linear vs. concave up vs. concave down.

Yeah, gotcha. Again kinda like y=x vs. y=x^2 vs. y=sqrt(x):

On all three, y(0)=0 and y(1)=1, but, with the accelerator pedal, meaning x, down halfway:

for y=x (more or less Normal mode),
y(0.5)=0.5

for y=x^2 (more or less ECO mode),
y(0.5)=0.25

for y=sqrt(x) (more or less Power mode),
y(0.5)=0.71...
