10 CFR part 474 is the federal law which dictates EV economy calculations for CAFE compliance. It was amended in 2023 to lower the MPGe rating from a ridiculous 300 - 400 MPGe for most EVs. The amendment states the Solar, Wind, Hydroelectric, AND Nuclear will be considered to operate at a 100% conversion rate to electricity. Imagine signing your name on a law that ignores all known laws of science! This extreme distortion of science delivers a falsely inflated energy grid efficiency, and therefore a higher conversion rate of one gallon of gasoline to electricity resulting in double the actual mileage for an EV. The whole purpose of the amendment was to force manufacturers to produce more EVs by lowering this MPGe rating. It's all complete scientific nonsense. Trust me I'm an EE. With this formula in 2029 a Lucid Air will be rated around 97 MPGe.
The MPGe mileage rating listed on EV window stickers is a completely different formula solely defined by the EPA without any Federal law or oversite. This statement is an even worse distortion of Physics and Thermodynamics than part 474 and says that there is 33.7 kW of electricity in one gallon of gas. The EPA apparently is aware of a electrical generator that can convert 100% of the heat from incinerating one gallon of gasoline into electricity. The NIST energy standard from 1994 for gasoline is 115,200 btu/gal or 33.7 kW/gal of heat. This will never, ever be equal to 33.7 kW of electricity. In fact the DOE calculated Eg or electricity from gasoline to be 12.3 kW/gal. Yet for 15 years the EPA has intentionally lied to every american and what's more disturbing is most people have no clue they have been punked.
Using the DOE number means the best EV, a Lucid Air, is a 50 MPGe vehicle. Fantastic car but not the 137 MPGe lie the EPA has stated. Sorry to burst the EV pundits bubble but that's what happens when it was blown up with a lot of hot air. Ev's are not one bit better than ICE vehicles and will leave a very large battery disposal footprint. At 12 million cars disposed of every year in America this may be the most overlooked issue.
