I don't like the Bolt name given they already have the Volt, but I don't like the idea of Volt-e even more.
As for Europe, Ampera-e seems like a mouthful and even though the Ampera has been discontinued, I think they'll do more harm than good because of the name association. Obviously the Ampera never caught on, so why recycle the name for a COMPLETELY different car? And they're fooling themselves by adding the -e on the end to distinguish the two. Perhaps they're trying to do what Toyota does with the Prius, and create an Ampera brand, but that doesn't make sense to me.
