Correct, I think only the Mustang, the Ranger and Edge are imported from the US, nice vehicles (especially the Mustang the Ranger) but which don't sell that much in absolute numbers. The rest of their line-up is I think produced in Europe.

Most of Ford's car lineup, even in the US, was designed in the EU (fiesta, focus) or in collaboration with Mazda (fusion). Cars like the Taurus/500/Montego/MKS evolved from Volvo platforms.

Ford is pretty heavily involved in Europe. Cars are bigger in Europe, so Ford cars tend to be developed there, while trucks and SUVs are bigger in America, so design of these vehicles is largely done in America.

And the EU tariffs are a part of the reason for that, though perhaps not the main reason.
