abaut the Fiat 500e , which US and/or EC/ECE-certificates/tests the car already fulfils, e.g. automotive FMVSS-Standards or –ECE-Standards

Trying to decrypt your question.. Electric / really coal powered cars are a fail in the US... manufacturers wishing to sell a certain model worldwide have to make three versions of each car: ECE left-hand drive ECE right-hand drive US/Canada FMVSS/CMVSS As a result of the large costs involved in retooling a car only for the American/Canadian market, most manufacturers won't even dream of spending all of the money to rebuild a model unless they think that it will be a reasonable success in North America. Consequently, the US and Canada actually have a shockingly low number of car models available compared to most other places. America protects its self in ways most have no clue of!
