One of the reasons given as far as why factories have been located in the South especially autos is to get them away from the power of the UAW and other unions. The perception has been labor rates salary wise are lower in that locale and the locals will accept it.I know what they built. I worked with them on some projects in Montgomery. Santa Fe, as you said, came later, but it was, for a long time, an afterthought as the crisis in 2008 pushed people to buy smaller vehicles. But still, Santa Fe would never be hit by truck tariffs. SUV's are not subject to that. Land Cruisers, or Touaregs or Q7's, were never subject to the truck tariff. Mazda B? Yes. VW Amarok? Yes. Truck tariffs did make some manufacturers build some facilities, but they are far from being the sole policy responsible for the car manufacturing boom in the Southeast or, generally, being responsible for foreign companies moving production here. Honda started building the Accord, and Toyota Camry when sedans ruled the market. I am not sure the manufacturing boom in the Southeast has anything to do with that. There are numerous manufacturing companies in the Southeast that don’t have anything to do with direct vehicle production or absolutely anything, from medical equipment to steel mills (Thyssen-Krupp). I mean, Alabama landed the first Airbus assembly outside the EU. Globalization was good for the Southeast. I mean, BMW is largest exporter of vehicles from the US If the EU imposes blanket tariffs like we did, SC will suffer. However, it seems the EU might target the tech sector and Tesla with specific tariffs and taxes. Michelin from SC exports a lot of tires to EU, as well as ZF transmissions.
The big issue BMW will deal with in SC is similar to the big 3 as far as import parts to build the vehicle. The engine and tranny come from Europe, for sure on the I6.
