That is the EPA CAFE classification, not how it is imported. That is the reason Ford got into trouble with the Transit Connect-they brought them over as passenger vans then ripped out the seats.
The Bronco Sport would be either a wagon or crossover, which I believe aren't impacted by that.
Also the tariff rates for importing ANY car unless you have a special deal (UK and South Korea for now) is 25%. I'm guessing their is some work arounds to that (I've saw that Ford is using a Bonded shipper?) to help mitigate the tariff issues.
Interesting if it will be shipped in as a "car" since right now, BS is considered a "truck" and if it continues that way, the Chicken Tax will hit it....unless of course, it comes in as an "incomplete" vehicle....one way around it would be to ship all NA without the hybrid battery and make/install it here in NA to complete it. If my memory of how the Chicken Tax works is correct.
