Exactly, as owner of one of the latest versions of Nissan cars with e-Power, I just can say that it is extremely inefficient, especially during winter, plus it isn't recognised at all as hybrid vehicle in Germany (it misses the "E" at the end of the car plate).
For comparison, the full classic gasoline engine with manual gearbox consumes less gasoline than the e-Power one. This is just some pure greenwashing, that isn't even explained at car dealerships and people can't say anything about it, when you ask for information.
Works like (?) an EV, it isn't an EV.
> it isn't recognised at all as hybrid vehicle in Germany
You surely mean that it is not recognized as plug-in hybrid vehicle.
We had the X-Trail AWD version of this. The plus side was getting around 850km to a tank of petrol. However, the EV-only range was very poor and the engine was quite harsh sounding when it spun up. Super happy to get rid of it and switch to BEV.
