2017 Prius Prime. There is a curved display marked with chg ev pwr. There are two bars. The Greenish/blue bar obviously is showing the amount of power from the electric motor and recharge. There is also a purple bar. Does anyone know what that indicates? The user manual does not address this.
It's a little hard for me to tell because the picture in the owners' manual isn't in color, but is your "greenish/blue bar" the narrower/shorter one here, and your "purple bar" the wider/longer one behind it? If so, I think you find the explanation under "ECO Accelerator Guidance" on page 213.
