Tariffs, diesel and computer chips are driving up costs for automakers
U.S. automakers report higher revenues but face rising costs due to tariffs, diesel, and computer chips. GM, Ford, and Stellantis saw increased sales of trucks and SUVs, with GM up 2.9%, Ford up 2%, and Stellantis up 1%. However, they warn of material cost increases, with GM and Ford estimating $2 billion in added expenses. EV sales dropped after the federal tax credit ended, but hybrids are gaining popularity.
