Basically, the AAPC is not battling the proposed 58 mpg limit. Instead, it wants to get rid of the new petroleum equivalence factor (PEF) for electric vehicles. The current eMPG ratings date back to the year 2000, which means a Ford F-150 Lightning has a rating of 238 MPGe. Using the new system proposed by the DEO, that figure will drop to 67 MPGe.
As you can imagine, this will drastically impact average fleet consumption. Under the old regulations, Ford would have no issue getting to an average of 58 mpg using its EV fleet to get that number down. But under the new regulations, the Lightning’s 67 MPGe will have an arguably insignificant impact on the 14 miles per gallon average the Shelby GT500 consumes.
The three Detroit automakers face a fine of $2,151 per car, which works out to a fine of $6.5 billion for GM and $3 billion for Stellantis.
