Mitsubishi has given us a few images of their concept car called the CA-MiEV just ahead of the Geneva Motor Show, and we only know they say it will have (up to?) 186 miles of range on one charge. That is probably on the Japanese test cycle which is pretty generous, but even if it is 110-120 miles that will be a game changer.
