In February, the U.S. Supreme Court ruled that President Trump exceeded his authority by imposing sweeping global tariffs under the International Emergency Economic Powers Act (IEEPA). The decision will reshape U.S. trade policy, and could have real consequences for automakers, dealerships and car buyers.
Prior to the decision, vehicle imports into the U.S. were operating under meaningfully elevated effective tariff rates. Across all imported vehicles, the blended effective tariff rate averaged about 15.3%. That number reflects the real-world duties being paid at the border after negotiations and adjustments, not just the original headline tariff proposals.
In many cases, the cost of these tariffs were passed onto consumers in the form of higher MSRPs. In other cases, automakers absorbed reduced incentive spending to offset them. This meant fewer low-APR incentives and cheap lease deals.
While vehicle prices are not going to fall 15% overnight, eliminating tariff pressure reduces upward pricing momentum. For now, the ruling gives manufacturers room to increase incentives, protect margins, or compete more aggressively on price.
Even vehicles assembled in the U.S. often rely on globally sourced components, so the ruling should have a positive effect on domestic automakers, too. If new car prices come down (even modestly), used car prices could also decline. That would be a win for all car shoppers in 2026 – although those looking to sell or trade-in a vehicle could see their trade-in values drop.
While the Court removed the existing tariff structure, it did not permanently eliminate the possibility of future trade restrictions.
