They are very different "vehicles". The class which allows Ami to operate in most European countries does not exist in most North American jurisdictions. A Smart is classified as a car and is road legal but an Ami is considered a quadricycle and as such is usually not considered road legal in most of North America.

Where I live it's not considered as any type of valid vehicle. If it sticks to quadricycle, the law is going to require pedals, limit it to 25 kph and a helmet for the passengers.

There are places in the US that have some "neighbourhood EV" laws that make these legal on local roads, but it's far from being common.

So if you are successful in importing one, you will most likely only be able to use it on private land.

Also, no insurance company is going to want to insure it.

And, to top ot all, the dealer, Stellantis, is apparently much more interested in selling pick-ups to North Americans.

...don’t expect to get one through Canadian or USA Stellantis dealer networks. They are 100% obsessed on moving EV versions of Jeeps, RAM pick-ups, the new Airflow crossover and their ProMaster truck offerings.
