During Stage-1A, the engine runs only for warm up the catalyzer and it does not provide driving power. If you start your Prius during Stage-1A, Prius is driven only by the motor, so your battery charge level is going down very quickly. That is inefficient situation.

My recommendation is one minute warm up on stand still, then start your Prius after that.

Thanks, Ken. The referenced writing is a classic, but I'm wondering how much of it still applies to the Gen3. Do you have a handle on that?

We have been observing the warm up cycle, but we have not completed yet on the Gen3.
In the mean time, it is very similar to Gen2 until Stage-3.
On the Gen3, the Stage-3 to Stage-4 transition, the idling check ceremony, is not required walking speed or complete stop.
It is done during slow down driving on the Gen3.

I do see a red arrow flowing from the ICE to the wheels. I assume that is a lie then?

Thanks for the warm up info. I have slowed down a bit lately on the first 300 m of each trip. I used to accelerate up to 50 km/h pretty quickly, now I keep below 40 (if I'm not holding up anyone else). That reduces battery depletion a lot, and I have more opportunity later to do some assisted glides. And after exiting the city and going to a steady 80 km/h cruising speed, it spends less time recharging the battery. During recharge, consumption is noticeably higher (~30%).

I'm gonna try slowing down more now I got this info to see if it has any noticeable effect. But I'm not going to sit and wait!

BTW how do you know stage 1B has started?
