Nobody mentioned some "confusion" about it. The fact is the PR is being deliberately vague with the differentiation between Hybrids and full electrics, hence the term electrification. They know most of their sold cars in the foreseeable future will still have an ICE in them. I understand they will have full EVs in the line up, and for their sake they better sell a few of them (they have to if they want to reach the EU emission targets).
My point is Peugeot excuse for dropping out is not honest, I very much doubt they would stay even if next year the WRX was already full electric. I think they might have something else up their sleeve, which will be more in line with their catalogue, and I think an Hybrid series (like WEC) would make more sense.
