U.S. auto fleet fuel efficiency flat in 2021

WASHINGTON – U.S. new car fleet fuel economy remained flat for 2021 models. This is because automakers sold more sport utility vehicles and pickup trucks compared to passenger cars. Meanwhile, the Detroit Three were lagging behind their foreign competitors.

The U.S. Environmental Protection Agency said Monday that the real-world average for the entire fleet is 25.4 miles per gallon for 2021 models, the same as 2020.

Automakers are responding to increasing vehicle emissions requirements by using credits earned in previous years or purchasing surplus credits from rivals.

Chrysler’s parent Stellantis had the lowest fuel economy of any automaker with 21.3 mpg in 2021, compared to 21.6 mpg for General Motors and 22.9 mpg for Ford.

Three US automakers had the lowest overall fleet fuel economy among the 14 major automakers.

According to the report, for the 2021 model year, Stellantis leads all automakers in buying emissions credits, earning 102.6 million megagrams of credits, while Tesla sold 72 million. General Motors bought him 28.3 million credits and Mercedes-Benz bought her 17.4 million credits. Honda sold 50.5 million credits and Toyota sold 38.9 million credits.

According to the EPA, carbon dioxide emissions per average new vehicle will drop 0.6% in 2021, down 2 grams from 2020 to a record low of 347 grams per mile.
