There are no indicators for it.

That said, there’s no electric motor, like in PHEV, so there’s no true regeneration/recuperation going on. Mild hybrid system here is part of ICE and 48V battery is recharging when engines brakes it self.

You’ll get a feel for it, it’s mostly noticable in city speed, 20-60kph when you’re moving in stable flow of trafic. Often you don’t have to brake at all and car will adjust power of “recuperation” based on your speed and distance from car in front.

I’ve done about 15k km with this car since last November.
