The Environmental Safety Company (EPA) was created by President Richard Nixon in 1970 to curb complicated and sometimes ineffective native and state environmental legal guidelines. The EPA stopped using dangerous leaded gasoline, and labored with automakers to place a catalytic converter beneath each new automobile for the 1975 mannequin 12 months—an motion that resulted in fewer tailpipe emissions, cleaner air, and extra fuel-efficient autos at the moment. Though leaded fuel caught round till the late Nineteen Nineties, based on this 12 months’s EPA automotive development report, “All car varieties are at document excessive gas economic system and document low CO2 emissions in mannequin 12 months 2020,” and that is true, regardless of a convincing shift away from the extra fuel-efficient sedan and wagon segments and towards giant vehicles and SUVs with decrease gas economic system and better CO2 emissions.

The EPA has examined 4230 totally different 2021 model-year autos, together with absolutely electrical autos. One thing to know: The massive EPA fuel-economy numbers on the window stickers are estimates, pushed by check information that simulates real-world driving. The truth is, these rankings are principally self-reported by automakers. Whoever performs the testing, be it the automakers or the EPA, that testing eliminates variables like temperature and site visitors. Though these scientific strategies are good for direct comparisons, the open street is not as reduce and dried as a sterile testing facility.
