I think you need to add the VW group to that list, as well as Toyota and maybe Honda.

VW's aren't so big in the US, but they are huge in Europe, and since the VW group shares platforms between Porsche, Audi and VW they have a huge advantage in economies of scale.

Toyota was the hybrid pioneer. Both Toyota and Honda have huge world-wide market shares and outstanding engineering groups. If / when they get into EVs, they will both be factors.
