The Environmental Protection Agency (EPA) finalized its tougher vehicle emissions requirements in December that parallel NHTSA rules. The EPA said its rules would result in 3.1 billion tons of avoided CO2 emissions through 2050. Major automakers on Wednesday backed EPA revisions to challenges posed by some states and some ethanol groups.

EPA rules would result in an actual fleet-wide average of about 40 miles per gallon (about 5.88 L/100 km) in 2026, up from 32 mpg (7.35 L/100 km ) under Trump rules. [The current U.S. standard is 24 mpg (9.8 L/100 km).] NHTSA rules give much the same in real world numbers.

NHTSA said Sunday it has reinstated a steep increase in penalties for automakers whose vehicles fail to meet fuel efficiency requirements for model years 2019 and beyond. The decision was a victory for Tesla that could cost other automakers like Chrysler parent Stellantis hundreds of millions of dollars or more.
