Regenerative braking is extremely overrated lol. I’ve owned 2 prii, another hybrid SUV, and a Model Y-P. Regen is just a pinch of the power consumption. Low single-digit percents. It’s cool not to waste, but it’s irrational to think it adds some tremendous amount. It doesn’t.

Regenerative braking in a Prius is different from what you find on a battery electric car. They run the motor in reverse as a generator and the electric motors in a battery vehicle are much larger and more efficient than what’s available even in a PHEV.

BEVs can brake without touching the brake pedal. A Prius doesn’t have a large enough electric motor to do that.

It's still not that efficient. About 25% last I checked

I mean I literally have a Tesla and it’s pretty insignificant. Not nothing, but also not much more than reclaiming some free losses.

How often do you drive long stretches down the hill? In this video guy driving downhill seems to be getting around 250 Wh/km, which seems rather significant.

I'm sure you can fare even better if you purpose-build a machine for just going downhill and charging and then going uphill: you basically have an electric plant on wheels.

You haven't lived near mountains then. I live in CO and it's extremly effective for the 2nd Gen, I just wish I had a bigger battery.
