What power is the twizy?

I’ve been looking for a few parts online and have come across lots of different variants on the pre-populated search criteria on various websites.
My logbook says my car is 8Kw (max net power).
Renault say they are either 4Kw (45) or 13Kw (80).
However a couple of sites seem to give the option of 15Kw (manufactured 2019+) still referred to as Twizy 80.

So, what is the actual power of the Twizy?
