Fuel economy for 2021 model year vehicles in the U.S. stayed flat with 2020 as people continued to buy less-efficient trucks and SUVs, according to an annual government report published Monday.
The fleet of new vehicles got 25.4 miles per gallon (10.8 kilometers per liter) for the model year, while greenhouse gas emissions dropped by 2 grams per mile to a record low of 347, the Environmental Protection Agency said in its annual Automotive Trends Report. The 2021 fuel economy figure ties a record set in model year 2020.
