Why do three automakers dominate the fast-growing hybrid car market?

There are only three automakers that control a majority of one of the most important segments of the American auto market – and none of them are American companies.

In the first half of 2026, sales of hybrid cars — not long ago considered a bridge to fully electric vehicles — rose nearly 20% year over year to reach a record market share of 15.4%, according to the Center for Automotive Research, nearly three times the share of pure electric vehicles.

“The only growth we are seeing is in hybrid market share,” said Elizabeth Krier, CEO of the Center for Automotive Research. “All other payment systems have lost market share year-to-date.”

It has been a boon for the few automakers that have invested heavily in the hybrid car market. Toyota, Hyundai Motor Group and Honda Together, they control 86% of it, according to auto market analysis firm Baum & Associates.

“Consumers want cars,” said Alan Baum, director of Baum & Associates. “The problem is that there are relatively few automakers that offer them.”

Toyota sold more than 600,000 hybrid cars in the first half of 2026 between its Toyota and Lexus brands. It controls half the market. Toyota’s hybrid lineup has pushed total U.S. vehicle volumes closer to top-selling GM, which has bet big on electric vehicles and has only one hybrid in its U.S. lineup in the Corvette E-Ray. GM told CNBC in an email that “hybrid vehicles have a role in our future product plans.”

Another automaker that has invested heavily in hybrid vehicles is Hyundai Motor Group, which owns the Hyundai, Genesis and Kia brands. It barely overtook Honda in the first half of 2026, according to data from Baum & Associates.

Hyundai has added hybrids to its wide range of vehicles, including large SUVs.

Honda remains the second best-selling hybrid brand in the country after Toyota. Hybrid cars represent 31% of Honda’s American sales, according to the company, It set a record for hybrid car sales in the United States in the first half of 2026.

“We are very pleased with the performance of our hybrid vehicles,” said Gary Robinson, vice president of automotive strategy at Honda Motor Company of America, the American arm of the Japanese automaker.

Higher fuel prices, wider choice and continued volatility over electric vehicle range and charging are pushing an unprecedented number of buyers toward hybrids. Historically, hybrid versions of cars have cost more than gas cars, Krier said, because of the more complex engines required.

But buyers can save between 30% and 50% on fuel costs, due to the better economy of hybrid cars, Krier says. She added that buyers of hybrid cars can recover the additional upfront cost within two to three years.

This has evolved since the introduction of the powertrain.

“The consumer value proposition has never been as compelling as it is today,” Krier said. “Gas prices were lower, so it was difficult to justify the premium. Early hybrids were mostly small cars, while American consumers were moving toward SUVs and trucks. It took time for consumers to understand the value proposition and economics, as well as product availability to match consumer preferences.”

Although Toyota created the Prius in 1997, the Honda Insight sedan was first on the U.S. market in 1999. The Prius followed in 2000, and from there, Toyota captured about 75% of the market share in the mid-2000s, according to CAR’s Krear. But at the time, hybrid car sales made up only 2% of all new car sales.

“If you go back at the time to some of the media reports, a lot of the feedback was, ‘What is it and why do we need it?’ We actually introduced it at a time when hybrid technology probably wasn’t necessary, but we felt a long-term commitment to the technology, and we felt that putting it in our lineup was good for consumers,” said Dave Crist, group vice president and general manager of the Toyota U.S. brand.

Toyota and Honda have stuck to the technology, investing much more in it than their competitors. And they continued even after that Tesla Other automakers have begun producing pure electric vehicles — something for which both automakers, especially Toyota, have received criticism from activists and shareholders.

Honda, long a leading maker of fuel-burning engines, will see its first loss in nearly 70 years as a public company in 2026, partly due to a $16 billion charge it took to restructure its electric vehicle division.

But the hybrid bet now seems clear-cut.

“Toyota pretty much had a north star strategy,” Krier said.

The company said it could more effectively reduce carbon emissions on a large scale by manufacturing huge quantities of fuel-guzzling hybrid cars that have smaller batteries, rather than a small number of electric vehicles with larger batteries. She said she also “met clients where they were.”

“Hybrid vehicles provide significant fuel savings without requiring changes in driving habits or charging infrastructure,” Krier said.

It also gave companies the opportunity to improve the technology, Robinson said. This has put them in good stead for the future.

In 2030, Baum & Associates expects the EV market share to rise to 9.5% and hybrids to make up a quarter of the market.

Meanwhile, Honda is planning to launch a new hybrid system to better suit larger vehicles, in order to maintain its position in the face of attack.

“At this point, there’s nothing really stopping us from competing with anyone in terms of hybrids,” Honda’s Robinson said.
