Detroit Three Project $2 Billion in Cost Headwinds for Fiscal Year

General Motors, Ford, and Stellantis reported third-quarter earnings on October 29, with all three companies projecting approximately $2 billion in added costs for the current fiscal year.

The cost pressures stem from rising prices for steel, copper, computer chips, and diesel fuel. These inputs are central to vehicle manufacturing and logistics, and their prices have climbed since 2025. The Trump administration imposed additional tariffs on imported metals, while global demand for copper and memory chips surged due to data center expansion and electric vehicle batteries. Diesel prices hovered near $6.35 per gallon in late October, close to a record high set in September.

General Motors chief financial officer Paul Jacobson stated that material and diesel costs would impact the company by as much as $2 billion this year. The firm is also absorbing about $2.5 billion in tariff expenses, a figure lower than earlier estimates due to refunds. Ford chief executive officer Jim Farley provided a similar estimate, noting that commodities, memory, and logistics costs represent a year-over-year headwind of about $2 billion. Stellantis chief executive officer Antonio Filosa described the higher prices for memory chips and raw materials as an industry-wide phenomenon. The company will provide detailed figures in its fourth-quarter report.

Revenues remained strong despite these costs. General Motors revenue rose 2.9% in the past year, while Ford increased 2% and Stellantis grew 1%. Light-duty truck sales led the performance. GM truck sales jumped 9%, and Stellantis U.S. pickup sales surged 34%. Ford’s F-Series continued to serve as a bestseller. The average new vehicle transaction price reached just over $50,000 in September, approaching a record high. Ford chief financial officer Sherry Ann House noted that customers have remained resilient despite higher fuel prices, interest rates, and inflation.

The end of the $7,500 federal electric vehicle tax credit on September 30, 2025, has shifted market dynamics. General Motors reported a 6% decline in third-quarter sales, partly attributed to a smaller EV market. Jacobson said the company is right-sizing its capacity to align production with demand. Ford executives did not address EV sales directly but highlighted the Fathom electric truck, which will be available for pre-order in early 2027 at a price under $30,000. Hybrid sales rose 27% in the past year as shoppers sought alternatives to high fuel costs. EVs currently account for about 6% of new U.S. car sales.

Tesla reported that its global sales fell compared to the same period last year, but its U.S. market share has recovered to nearly 52% of new EV sales. Ivan Drury of Edmunds said buyers are defaulting to Tesla as other automakers adjust their investment strategies. On its earnings call, Tesla chief executive officer Elon Musk discussed a potential merger with SpaceX, noting that special committees at both companies are discussing the possibility. Musk stated that shareholders would need to be supportive of combining the two entities.

General Motors and Ford stated that growth in software services, parts, and other business segments is helping offset the $2 billion cost headwinds. Stellantis executives indicated they will release more specific data on these expenses in the fourth quarter. The Detroit Three are adjusting their supply chains and product plans to accommodate higher input costs and shifting consumer preferences toward hybrids and large trucks.
