Cox Automotive bumped its 2026 U.S. new-car sales forecast to 16.1 million units last week, up from 15.8 million. The reason isn’t a healthier market. It’s a wealthier one.
Buyers earning more than $150,000 a year now account for 43% of all new-vehicle purchases in 2026, up from 29% in 2020. That is not a gradual shift. That is a market being hollowed out from below and backfilled at the top.
Meanwhile, buyers earning under $100,000 have dropped from half the market in 2020 to just 36% this year. The middle and working class aren’t buying fewer cars because they don’t need them. They’re being priced out by near-record transaction prices, stubborn interest rates, and fuel costs that refuse to cooperate.
Charlie Chesbrough, Cox Automotive’s senior economist, called the outlook “cautiously optimistic” during a Sept. 17 webinar hosted by the American International Automobile Dealers Association. He pointed to low unemployment, stronger job creation than 2025, and a surging stock market as reasons to feel good.
Feel good if you’re in the right tax bracket, anyway.
Even at 16.1 million, the revised forecast still represents a 1.2% decline from the 16.3 million vehicles sold in 2025. The old estimate of 15.8 million would have meant a 2.9% drop. So the upgrade amounts to a smaller retreat, not an advance.
Chesbrough did not shy away from the fragility underneath the numbers. Consumer spending drives 70% of the U.S. economy, and he acknowledged rising recession fears. Even some affluent buyers could start pulling back if conditions shift. A stock market correction, a spike in layoffs, or an escalation in geopolitical tensions could change the math quickly.
The industry has been leaning on high-income consumers for years now, but 2026 has made the dependency unmistakable. Automakers and dealers have responded predictably, loading lots with expensive trucks, luxury crossovers, and fully optioned EVs that command $50,000 or more. The entry-level sedan, once the backbone of American car buying, has become an afterthought.
That works until it doesn’t. A customer base concentrated at the top is inherently volatile. Wealthy buyers are more sensitive to portfolio swings, more likely to delay discretionary purchases when sentiment turns, and harder to incentivize with rebates that erode margins.
Dealers are already feeling the pressure. A separate Cox report from early September showed affordability concerns and a cloudy sales outlook dampened dealer optimism in the third quarter. The people selling the cars see what the economists are still hedging around.
The 16.1 million figure will get cited in earnings calls and investor decks as evidence the market is holding. Strip it down and the picture is more complicated. Fewer Americans can afford a new car than at any point in recent memory, and the ones who can are keeping the machine running on a base narrower than it looks.
Chesbrough’s word was “cautiously.” The industry should pay closer attention to that qualifier than to the number that followed it.
