The article is not very clear what the 6.67 multiplier is used for. It gives more weight to electric vehicles, when calculating the overall average efficiency of all vehicles produced by a manufacturer. As a result, a manufacturer can produce less electric vehicles, and more traditional vehicles, and still meet the required "average efficiency". https://www.instituteforenergyresearch.org/renewable/cafe-compliance-will-be-harder-with-doe-proposed-rule-change/ https://www.instituteforenergyresearch.org/renewable/cafe-co... I am not sure the author of the WSJ opinion piece understands this. They make it sound like the multiplier was an unfair advantage for EVs. It is the opposite.
