With the upcoming start of production at its new plant in Celaya, Mexico, Honda expects that as much as 90% of the vehicles it sells in North America will soon be produced locally. And it’s not alone. Toyota, Nissan, Volkswagen are steadily expanding their own production bases in the U.S., Canada and Mexico, ramping up regional production just three decades after Honda opened the first Asian-owned “transplant” assembly line in Marysville, Ohio. In fact, a new study says foreign makers will account for well over half of all added vehicle production in North America by the end of the decade.
