There's far too much talk and stagnation on Wikipedia — I've seen discussions go on for two years without a change being made — but I'll go so far as to say that Z.E. is much more than a range of cars by Renault as they are not ICE vehicles at all. They are EVs, a completely different class of vehicle. Renault is making an dedicated commitment to develop these EVs and bring them to market and the fact that two of the four current Z.E. vehicles are based on existing ICE vehicle bodies doesn't alter that fact. We'll see what Renault will announce next for Z.E. but according to Renault this class/range/whatever will only grow.
