"In the U.S., gas-powered cars have stopped making big efficiency gains. Some automakers’ offerings have gotten less efficient as they swap out sedans for SUVs."

"In 2017, Mazda announced its “Sustainable Zoom Zoom 2030 Vision,” which promised to “perfect an internal combustion engine that produces fewer carbon dioxide emissions.”

Over the next five years, however, the average fuel efficiency of the new cars Mazda sold in the United States dropped by nearly 7 percent, according to recent data from the Environmental Protection Agency.

And Mazda is not alone. Five other automakers — Honda, Subaru, Volkswagen, BMW and GM — sold cars that were less efficient, on average, in 2022 than in 2017."
