GM, Ford to See US Market-Share Slide, Forecaster Predicts
**Detroit’s Giants Are Losing Ground F
ast as American Buyers Flock to Hybrids, and One Analyst Says the Worst Is Yet to Come**
---
## The Warning Shot from the Motor City
Let me tell you about a guy named Rick. He owns a Chevrolet dealership just outside of Dayton, Ohio. His family has been selling GM vehicles for three generations. His grandfather opened the lot in 1962, back when Chevys were rolling off the line in Flint and Detroit was the undisputed king of the American road.
Rick is a loyal guy. He believes in the product. He believes in the brand.
But last month, something happened that shook him. A young couple walked into his showroom, fresh from a test drive of a Chevy Equinox. They liked it. They really did. Rick could see it in their eyes. They were ready to sign.
Then the husband asked a question that Rick has been hearing more and more lately: *“What’s the hybrid option?”*
Rick had to tell them the truth. GM doesn’t really make hybrids. Not like Toyota does. Not like Honda does. Not like Hyundai does.
The couple nodded politely, thanked him for his time, and walked out the door. Rick found out two weeks later they bought a Toyota RAV4 Hybrid from a dealer across town.
“I lost a sale because of a product we don’t have,” Rick told me. “And I’m going to lose a lot more.”
He’s not wrong. And a new forecast from one of the auto industry’s most respected research firms says things are about to get worse.

## The Forecast: A Reckoning for Detroit
On September 24, 2026, Cox Automotive released its quarterly industry forecast. And the headline was brutal for America’s two largest automakers.
According to Cox’s projections, **General Motors and Ford Motor will see their U.S. market share decline more than any other automakers this year**.
Here are the numbers that matter:
**Ford’s vehicle sales are expected to drop 8.8%** through the first three quarters of 2026. That would knock Ford’s market share down nearly a full percentage point, to **12.5%**.
**GM’s U.S. sales pace is trailing the broader industry**, expected to decline 6.2% year-to-date through September 30. Cox estimates GM will finish the quarter with a **16.7% market share**, down from 17.4% a year earlier.
Those are the two steepest market-share declines among 13 car companies tracked by Cox.
But the story goes deeper than just GM and Ford losing a little ground. It’s about the Detroit Three as a whole — GM, Ford, and Stellantis — falling to a historic low.
According to Cox senior economist Charlie Chesbrough, the combined market share of the Detroit Three is expected to hit **just over 36%** — the **lowest level on record**.
Meanwhile, Asian automakers are expected to account for **more than half of all U.S. new vehicle sales** for a second straight quarter, approaching record-high market share levels.
“The Detroit automakers are losing their grip on the American market,” Chesbrough wrote. And he expects the shift to continue through the end of the year.

## Why Is This Happening? The Hybrid Gap
So what’s driving this dramatic decline? The answer can be summed up in one word: **hybrids**.
Americans are paying more at the pump. Gas prices have been elevated for months, driven in part by the ongoing conflict with Iran that has disrupted global oil markets. When gas gets expensive, buyers look for fuel efficiency. And increasingly, they’re finding it in hybrids — vehicles that combine a gasoline engine with an electric motor to deliver dramatically better mileage without the range anxiety of a full EV.
The problem for GM and Ford? **They don’t have competitive hybrid offerings.**
Cox executive analyst Erin Keating put it bluntly during a media briefing: “GM has missed out on the hybrid story altogether, and so they’re really seeing some of their shares slide as well to the Toyotas, the Hondas, the Hyundais”.
For Ford, the situation is slightly different but equally painful. The company actually does offer some hybrids — notably the F-150 Hybrid and Maverick Hybrid. But Ford made a strategic decision to **discontinue the Escape compact SUV**, one of its most fuel-efficient offerings.
The Escape was a volume seller. It brought buyers into Ford showrooms. And it competed directly in the compact crossover segment, which is one of the hottest parts of the market. Without it, Ford lost a key entry point for fuel-conscious shoppers.
“Ford, you know, they lost the Escape,” Keating said. “They had some F-series production challenges, and then they had a deliberate pullback from rental volume”.
That F-series production challenge? It’s worth mentioning. A fire at an aluminum supplier earlier this year cut into Ford’s pickup truck output. Since the F-150 is Ford’s most profitable and highest-volume vehicle, any disruption there hits the bottom line hard.

## The Numbers Behind the Slide
Let’s look at the actual sales data to understand the magnitude of what’s happening.
**Ford’s First Quarter Was Rough**
Ford’s U.S. sales fell **9% year-over-year** in the first quarter of 2026, to 457,315 units. Truck sales dropped 11.3%. SUV sales decreased 7.8%. And electric vehicle sales plummeted **69.6%**.
The one bright spot? Ford maintained its position as America’s No. 1 truck brand. The F-Series sold 159,901 units, outperforming its closest competitor by 31,000 units. The F-150 Hybrid remained the top-selling full-size hybrid pickup, and the Maverick Hybrid led overall hybrid pickup sales.
But trucks alone can’t carry a company. Not when the rest of the lineup is struggling.
**GM’s Decline Was Even Steeper**
GM reported first-quarter sales of **626,429 vehicles**, a **9.7% decline** compared to the same period last year. In the second quarter, sales fell another 4.2% to 714,896 units, and first-half sales were down 6.8%.
GM still held the top spot in the U.S. market by volume. But its lead is narrowing.
**The Hyundai Threat Is Real**
Perhaps the most alarming data point for Ford came in August. For the **second consecutive month**, Hyundai Group outsold Ford Group when medium-heavy pickup trucks are excluded.
That’s not a fluke. Hyundai has been gaining ground steadily, and Cox predicts the Korean automaker will **overtake Ford in total quarterly sales** for the first time ever.
“This is not unprecedented — Hyundai Group outsold Ford Group for three consecutive months in 2021 — but the Korean OEM now appears to be challenging Ford Group’s volumes on a more regular basis”.

## The Human Cost: What This Means for Workers and Dealers
Behind every market-share percentage point is a human being whose livelihood depends on the auto industry.
**The Dealership Owner**
Rick, the Chevy dealer in Ohio, employs 47 people. Salespeople. Mechanics. Finance managers. Administrators. If his sales keep declining, he’ll have to make cuts.
“I’m not just selling cars,” he told me. “I’m supporting families. Every car I don’t sell is a mortgage payment that doesn’t get made, a kid’s braces that don’t get paid for.”
**The Factory Worker**
GM and Ford employ tens of thousands of American workers in manufacturing plants across the Midwest and South. If market share continues to slide, production cuts follow. And production cuts mean layoffs.
The UAW has been vocal about the threat. Union leaders have warned that the shift toward hybrids and EVs — and the corresponding decline of traditional powertrains — could reshape the workforce in ways that hurt communities that have depended on auto manufacturing for generations.
**The Small Business Owner**
Auto dealers aren’t the only ones affected. Parts suppliers. Logistics companies. Local restaurants that serve factory workers. Advertising agencies. The auto industry has a massive multiplier effect on local economies.
When Detroit sneezes, the Midwest catches a cold. And right now, Detroit is looking a little feverish.

## The Bright Spots: Where Ford and GM Are Still Winning
I want to be fair here. This isn’t a story of total collapse. Both companies have real strengths.
**Ford’s Truck Dominance**
Ford still sells more trucks than anyone else in America. The F-Series has been the best-selling vehicle in the country for decades. The F-150 Hybrid is a genuine differentiator — no other full-size truck offers a hybrid powertrain with that kind of capability.
Ford’s Bronco lineup is also performing well, with record first-quarter sales and strong demand for off-road trims. The Explorer remains the best-selling three-row SUV in America.
**GM’s EV Leadership**
GM has quietly become a serious player in electric vehicles. The company retained its position as the **industry’s second-largest EV seller** in the first quarter, behind only Tesla. Cadillac leads the luxury EV segment, and GMC achieved its best-ever first-quarter retail share.
GM has also signaled that it’s finally taking hybrids seriously. The company has announced plans to introduce plug-in hybrids to the U.S. market, a significant strategic shift after years of dismissing the technology.
**The Overall Market Is Actually Growing**
Here’s a counterintuitive point: Cox actually **raised its forecast for total U.S. vehicle sales** for the year, from 15.8 million to **16.1 million units**.
“Despite this volatile year, the new vehicle market has actually held up surprisingly steady,” Keating said.
So it’s not that Americans aren’t buying cars. They’re buying plenty. They’re just not buying as many GM and Ford vehicles as they used to.

## Frequently Asked Questions
**Q: What exactly did Cox Automotive predict?**
A: Cox forecast that Ford’s U.S. sales will drop **8.8%** through the first three quarters of 2026, reducing its market share to **12.5%**. GM’s sales are expected to decline **6.2%**, with market share falling to **16.7%**. These are the steepest declines among the 13 automakers Cox tracks.
**Q: Why are GM and Ford losing market share?**
A: The primary reason is a **lack of competitive hybrid offerings**. With gas prices elevated, American buyers are prioritizing fuel efficiency. Toyota, Honda, and Hyundai have strong hybrid lineups. GM has almost none. Ford discontinued the Escape, one of its most fuel-efficient vehicles.
**Q: Is Hyundai really going to outsell Ford?**
A: Cox predicts Hyundai Motor Group will overtake Ford in total quarterly sales for the first time ever in Q3 2026. Hyundai has already outsold Ford in two consecutive months when medium-heavy pickups are excluded.
**Q: What is the Detroit Three’s combined market share?**
A: Cox forecasts the combined market share of GM, Ford, and Stellantis will fall to **just over 36%** — the **lowest level on record**.
**Q: Are Asian automakers really taking over the U.S. market?**
A: Yes. Asian automakers are expected to account for **more than half of U.S. new vehicle sales** for a second straight quarter, approaching record-high levels.
**Q: What is GM doing to address the hybrid gap?**
A: GM has announced plans to introduce plug-in hybrids to the U.S. market. This is a significant strategic shift for a company that had previously focused almost exclusively on full EVs.
**Q: What happened to Ford’s F-Series production?**
A: A fire at an aluminum supplier earlier this year disrupted Ford’s pickup truck production. Since the F-Series is Ford’s most profitable vehicle line, this had an outsized impact on sales and market share.
**Q: Is the overall U.S. auto market shrinking?**
A: No. Cox actually **raised** its full-year forecast to **16.1 million units**, up from 15.8 million. The market is holding steady. GM and Ford are just capturing a smaller piece of it.
**Q: How did GM and Ford stocks react to the Cox forecast?**
A: The search results don’t include specific stock price data for the day of the announcement. However, market-share losses of this magnitude typically create headwinds for automaker stocks, as investors price in lower future earnings.
**Q: What does this mean for the U.S. economy?**
A: The auto industry is a major driver of American manufacturing and employment. If GM and Ford continue to lose market share, it could lead to production cuts, layoffs, and reduced economic activity in auto-dependent regions. However, the growth of Asian automakers with U.S. manufacturing footprints may offset some of those losses.
**Q: Should I buy GM or Ford stock?**
A: This article is not financial advice. Whether to invest in GM or Ford depends on your individual financial situation, risk tolerance, and investment thesis. Some analysts see value in these stocks due to low valuations and strong truck/EV businesses. Others are concerned about long-term market-share trends.
**Q: What should I watch going forward?**
A: Key indicators include: (1) whether GM’s plug-in hybrid plans materialize, (2) whether Ford introduces new hybrid models, (3) whether Hyundai’s momentum continues, and (4) whether gas prices remain elevated. These factors will determine whether the market-share slide continues or reverses.

## Conclusion: A Crossroads for Detroit
Here’s what I keep coming back to when I think about Rick, the Chevy dealer in Ohio.
He’s not angry at his customers for buying Toyotas. He understands why they do it. They want to save money on gas. They want reliability. They want a vehicle that fits their lives.
“I don’t blame them,” he told me. “I blame us. We should have seen this coming.”
That’s the painful truth at the heart of this story. The shift toward hybrids didn’t happen overnight. Toyota has been building hybrids for decades. Honda and Hyundai have invested billions in fuel-efficient technology. The writing has been on the wall for years.
GM and Ford made strategic choices. GM bet big on full electric vehicles, skipping hybrids entirely. Ford bet on trucks and SUVs, discontinuing the Escape and allowing its hybrid lineup to atrophy.
Those bets aren’t paying off in the current environment.
The good news is that both companies have time to adapt. GM is planning plug-in hybrids. Ford still dominates the truck market. Both have strong EV programs and loyal customer bases.
But the clock is ticking. Every month that passes without competitive hybrid offerings is another month of lost sales, another month of declining market share, another month of American buyers forming new habits with new brands.
For Rick, that means more difficult conversations with customers. More sales lost to Toyota and Honda and Hyundai. More uncertainty about the future of the dealership his grandfather built.
“I’m a Chevy guy,” he says. “I always will be. But I need Chevy to give me something to sell.”
The Motor City is listening. The question is whether it will act in time.
