If they lose significant ground to Chinese companies in Canada, Mexico and other countries where they once dominated, G.M. and Ford could gradually become niche manufacturers, said Erik Gordon, a professor at the Ross School of Business at the University of Michigan. They will end up primarily making and selling large pickup trucks and sport-utility vehicles favored by many Americans but that tend to sell less well in much of the rest of the world.
