September 2026 U.S. Auto Sales Forecast & Automotive Industry Outlook

U.S. Automotive Market Forecast for Dealers

HOUSTON, TX, UNITED STATES, October 2, 2026 /EINPresswire.com/ -- Fountain Forward projects the upcoming economic release for U.S. Light Vehicle Sales will be a 16.4 million seasonally adjusted annual rate (SAAR) for September 2026.

This automotive market forecast reflects a market that came out of the summer with more gas in the tank than most people expected. August was the sixth straight month above a 16 million pace, and September gets a little help from the calendar this year, with Labor Day weekend landing in September's numbers instead of August's.

Labor Day weekend helps dealers move 80,000 to 100,000 units and its placement in August or September sometimes moves SAAR around even though SAAR features an adjustment for it.


Automotive Industry Outlook

Fountain Forward's automotive industry outlook for September 2026 points to a market heading into the fourth quarter with leaner lots. Dealers are selling faster than they can restock. Industry days' supply dropped to 73 in August, the lowest level since spring 2025, and inventory is tightest at the affordable end of the market at 54 days, right where payment-sensitive shoppers need it most.

Affordability is still the thing that could slow this market down. The average new-vehicle payment hit a record $812 for August. The model-year changeover is also running well behind last year's pace, which could shift the timing of incentives and closeout pricing as the year winds down. Dealers should keep a close eye on manufacturer programs, inventory availability, and how shoppers respond over the next few weeks.

By analyzing proprietary sales performance, high-frequency economic indicators, dealer benchmarks, and proprietary behavioral signals, Fountain Forward delivers an automotive market forecast designed to help dealers anticipate near-term demand, optimize marketing investments, and align inventory strategy in a shifting economic environment.


Auto Industry Insights for Dealers

"A hidden signal in August’s sales crossed our screens when we noticed that unit sales were strong without the push and pull from the clearance markdowns and dealer incentives that start to show up in a typical August. We are still on that signal in September. We like the underlying trend of consumer spend here and these inventory constraints are cropping up because the American consumer has just surprised everyone in automotive." said Stephen Jurgella, CEO of Fountain Forward


Key Dealer Takeaways for September

Inventory Strategy
Supply looks very different depending on the badge out front. Toyota, Lexus, and Honda stores are running lean, while Stellantis, Buick, and Lincoln are still carrying heavy inventory. If you are tight, protect gross on the affordable units that are hardest to replace. If you are heavy, work your aged units now, before more model-year 2027 inventory shows up. 2027 model year vehicles are running late with MY27 comprising 12% of inventory in September vs 24%+ in recent years.

Marketing Strategy
The new models have not hit lots yet but they are coming. So ‘27 incentives and ‘26 clearance markdowns should drive volumes in October. Payment-focused messaging, and trade-in value are still what get shoppers' attention. And put your hybrids front and center, because buyers across nearly every brand are asking for them.

F&I Focus
With payments at record highs, expect more negative equity, longer loan terms, and tougher approvals. Showing clear, honest payment options early keeps deals from falling apart at the end.

Sales Execution
Shoppers are out there, but they're taking their time and comparing more stores before they commit. Quick responses, steady follow-up, and tight lead handling will make the difference heading into Q4.
