GM, Ford Q3 US New Vehicle Sales Seen Dropping YOY, Cox Says

05:36 AM EDT, 09/25/2026 (MT Newswires) -- General Motors' (GM) new US vehicle sales are expected to drop 5.2% year over year in Q3, while Ford Motor (F) is likely to see a 7.1% decline, Cox Automotive said Thursday. Tesla's (TSLA) sales for the quarter are seen slumping 31% on an annual basis, while Stellantis (STLA) is expected to post a 1.3% drop, according to the report. Toyota Motor (TM) is projected to post a 2.2% year-over-year sales increase in the period, while Hyundai and Honda Motor (HMC) are set to report sales growth of 6.5% and 12%, respectively, Cox said. The firm lifted its 2026 new-vehicle sales forecast to 16.1 million units from 15.8 million, reflecting strength in the market despite higher fuel prices, elevated interest rates and ongoing economic uncertainty, it said. "Asian brands are expected to account for more than half of US new-vehicle sales for a second consecutive quarter, approaching record-high market share levels," Cox Senior Economist Charlie Chesbrough said. "At the same time, brands from the traditional Detroit 3 are forecast to fall to just over 36% market share, the lowest level on record."
