Detroit carmakers feud over Trump’s threatened truck tariffs

(Bloomberg) — U.S. carmakers have mounted a furious, last-minute lobbying blitz over the Trump administration’s potential tariffs on medium- and heavy-duty trucks, in a fight pitting Detroit’s legacy automakers against each other.

Stellantis NV has lobbied the administration in recent days to waive or soften a possible 25% tariff that could otherwise hit medium-duty Ram pickups the company makes in Mexico, according to people familiar with the matter.

General Motors Co. and Ford Motor Co., meanwhile, have urged Trump administration officials to dismiss the request, said the people, who asked not to be identified because the discussions are private. Ford argued that shielding Stellantis from the medium-duty truck tariffs would hand the company a cost advantage over US-assembled trucks tha
