Interesting question, it looks like they are / will be brushelss:
> Group will gradually embed new technological improvements from 2024 on its EESM: stator hairpin, glued motor stack, *brushless* and hollow rotor shafts.

That said, what sibling says about the maintenance problems is very true. :-/
All sources point that their 2025 models are still using brushed rotors. Here is a teardown video it's from Nisan car but it's using a Renault electric motor https://www.youtube.com/watch?v=BFmp9ODkCA8 .
In the picture at Renault website (section describing their next gen 2027 motors) you can clearly see the 2 slip rings on right side. That might be just a placeholder using their last gen motor, but I would expect that they would mention it if their next gen was brushless while the current one has brushes.
Brushless seems to be a thing that they have described as future work for at least 5 years but it's not there yet.
Compared to an ICE, maintenance of brushes is still quite an improvement.
