BioSehnsucht
Model 3 LR
Pretty sure it's more common for the auto maker to perform their own tests to the EPA testing regimen and provide the results to the EPA with everyone taking it on faith that nobody cheated. Since the EPA testing regiment is a parody of actual driving at best, as nobody drives the speed limit, you can't really "gotcha!" anyone since the testing isn't real world in the first place or claimed to be (only ever claimed to be EPA, or WLTP, or whatever range).Well then "Watch out EPA". Range is nothing that you can claim. It has been certified by the EPA so take it up with them.
Of course, that won't stop anyone from trying to "gotcha!" - I especially love it when people (generally on the Internet) compare NEDC or WLTP range against EPA and claim victory for whichever vehicle was using the NEDC/WLTP range in the comparison.
