The emissions and efficiency standards for vehicles have been a big success, according to a new analysis by the Union of Concerned Scientists (UCS). The Union of Concerned Scientists reported that 10% of new passenger cars and trucks sold today already meet standards for 2020 and beyond, and the majority of those are powered by gasoline and diesel engines.

With innovative technologies being deployed across all types of vehicles, consumers have more choices for models that save thousands of dollars in fuel costs, and automakers are demonstrating they can deliver even more efficient vehicles in the future.

“The efficiency and emissions standards are working—all you have to do is look at cars and trucks that are on the road today to see it,” said Dr. Dave Cooke, vehicles analyst at UCS. “Automakers are meeting the challenge of making cleaner cars, and Americans are buying those cars. The standards are delivering even faster than expected.”

Manufacturers are more than a year ahead of regulatory requirements, the UCS study finds:

  • More than 100 model variants meet or exceed the 2020 standards—including not just hybrid and electric vehicle models, but also conventional gasoline- and diesel-powered vehicles.
  • Seventy percent of sales of vehicles that meet or exceed 2020 standards are vehicles with conventional gasoline- and diesel-powered engines.
  • Six of the 10 best-selling vehicles in America have model variants that meet or exceed 2020 standards, including the Ford F-150, the Dodge Ram and the Honda CR-V.
