EPA stopped publishing EV ranges?

Where can I find a story about this decision? Is it permanent?

They used to have both city and hwy range figures, but now there's only the one. Our editor-in-chief asked the EPA why and they didn't respond. He believes it may just be a matter of resources at the agency.

Another editor just mentioned that some manufacturers appear to provide city/highway info, and that we'll see what will happen in 2022.
 
Sorry, I don't remember two range numbers. If given the task for the '2021 Tesla Model 3 Standard Range Plus RWD':
  • 133 MPGe highway
  • 150 MPGe city
  • 263 miles total range (typically highway at ~63 mph)
  • ~297 miles city = (150 MPGe city / 133 MPGe highway) * 263 miles highway
I've used partial fractions of the city and highway MPGe to estimate the city range. I don't understand if we've gained insight. For example, applied to the '2022 Lucid Air G Touring AWD w/19in wheels:'
  • 132 MPGe highway
  • 130 MPGe city
  • 516 miles total range
  • 508.1 miles = (130 MPGe city / 132 MPGe highway) * 516 miles highway
This suggests the Lucid has some unusual characteristic that their highway mileage is better than their city mileage. There is another way.

Using the published drag coefficients, one can calculate the drag power across the operational mph range. But I have little interest in these non-Tesla, EV cars.
