Honda again leads the U.S. auto industry with both the highest fleet average fuel economy and lowest fleet average CO₂ emissions of all full-line automakers in America, according to a new report from the U.S. Environmental Protection Agency (EPA). Honda continues a more than 40-year history of fuel-efficiency leadership as the most fuel-efficient automaker for the 2020 model year (MY 2020), the latest year for which full data is available, which forms the basis of the EPA report.

The 2021 EPA Automotive Trends Report ranked Honda first among full-line automakers and second overall with its U.S. fleet average “real world” fuel economy increasing to 29.1 miles per gallon (mpg), 3.7 mpg higher than the industry average for MY2020. Similarly, Honda’s fleet average CO₂ emissions was 305 grams/mile, an improvement of 7 grams/mile from 2015 results and 44 grams/mile lower (better) than the industry average for the 2020 model year.

Honda already has set a new annual record in 2021 for sales of electrified vehicles in America, exceeding 90,000 units, despite the significant challenge of multiple supply issues, and expected to top 100,000 electrified vehicles by the end of the year.

Earlier this year, Honda outlined the company’s vision for global sales of electrified vehicles as part of Honda’s strategy to achieve carbon-neutrality for its products and corporate activities by 2050. This vision calls for the sales ratio of battery-electric and fuel cell electric vehicles in North America to progress from 40 percent by 2030 and 80 percent by 2035 to 100 percent by 2040. More details about that announcement, are available here.

The EPA’s very first ranking of America’s most fuel-efficient vehicles in 1976 had the Honda Civic ranked number one, and subsequent reports have consistently shown Honda among the leaders in EPA’s annual fuel efficiency measurements. That means that for more than 40 years, Honda has made fuel efficiency a priority in its products.
