New-vehicle supply held steady in the U.S. in April as auto brands worked to reduce 2025 units with strategic incentives.

The steady effort reduced industrywide inventory 1% to about 2.9 million units, or 78 days’ worth, resulting in 2026 units comprising 93% of remaining supply, according to Cox Automotive data.

The balancing act protected prices on new units while leaving brands with ample new supply to meet demand, Cox said. 

Days’ supply at the end of the month was still about 16% higher than a year earlier, when many consumers beat a path to dealers to get ahead of tariff-induced price hikes.

Inventory was down month-over-month despite sales also declining in April, Cox said, observing that automakers are supplying 2026 model-year units at a “more measured pace.”

“The result is a more controlled inventory environment, where overall supply and incentive levels remain mostly stable,” said Cox Executive Analyst Erin Keating.

Consumer affordability factored into some overseas’ brands supply pictures as demand ate into sedan segments’ inventories, Cox found.

“April’s inventory data points to a market that is neither tightening nor loosening materially but rather holding steady in the face of strengthening headwinds,” Keating said. 

“As the industry moves through the second quarter, the ability to sustain that balance will determine whether stability holds or new pressures begin to emerge.”
