An Automotive News opinion column published this week, headlined "Detroit 3 need to grow a spine on tariffs," is calling on General Motors (GM), Ford, and Stellantis to drop their cautious public posture and push back harder against U.S. duties on imported vehicles and parts.

The Detroit 3 — shorthand for the three automakers still headquartered in metropolitan Detroit after decades of consolidation — hold roughly 40 percent of U.S. light-vehicle production capacity. Their three U.S. brand portfolios also dominate domestic new-vehicle sales. That scale gives them unusual leverage in Washington tariff fights, leverage the column argues the OEMs (original equipment manufacturers) have so far declined to use.

The phrase "grow a spine" is the columnist's provocation. Automotive News, the dominant U.S. automotive trade publication based in Detroit, has run extensive coverage of the tariff regime since duties on imported vehicles and parts began reshaping sourcing plans. A column with this headline aims to widen the debate inside supplier purchasing offices and OEM government affairs teams, where the editorial line of record on industry policy is read each Monday morning.

The tariff backdrop matters. Two decades of just-in-time sourcing have pulled Detroit 3 supply chains deep into Mexico, Canada, and East Asia. The same cross-border parts flows that kept unit costs low now sit exposed to country-of-origin duties. Inventories built around that footprint are, in many cases, the very inventories the automakers are trying to protect by not antagonizing trade policymakers.

The three companies have not responded identically. Stellantis, smallest of the three in U.S. volume and historically the most exposed to imported content, has lobbied loudest on trade issues. Ford and GM have preferred quiet bilateral channels with U.S., Canadian, and Mexican officials over public combat. The column reads that restraint as a strategic mistake.

What does the column change?

A column from Automotive News moves the conversation inside the industry without naming names or inventing news. It raises the cost of silence the next time a tariff tranche opens and gives trade-association executives cover to take harder public positions. It does not bind any CEO to a specific demand or vote. The effect is reputational, not contractual.

What to watch

• Treasury and Commerce decisions on the next rounds of vehicle and parts duties, expected across 2026
• Alliance for Automotive Innovation statements on cross-border parts flows
• Detroit 3 Q4 earnings calls in late January, where CFO commentary on input cost inflation will telegraph whether the public line is shifting
• Any Stellantis disclosure of tariff cost impact, since the company has historically been most willing to quantify the burden
