I think this is a bit misleading. Edmunds and the EPA ran two very different tests. For instance, Edmunds drives the car until it indicates it's empty. However, in the EPA test, "the vehicle is driven over successive city cycles until the battery becomes discharged" [1]. Tesla vehicles, like many others, have a not so insignificant buffer of "extra" miles that you can still use after the vehicle indicates that its "empty".
Furthermore, Edmunds tested the Teslas at temperatures that are roughly 14F lower than the 68F used by the EPA. This can make a big difference in the range you get.
My point is that these articles are acting like they are comparing apples to apples--the EPA test vs the Edmunds test--but they're not.
I admit that I'm a Tesla fan and shareholder. But my first loyalty is to the truth. Ding Tesla and Elon when they mess up. Nobody is above reproach or constructive criticism.
So let's not pretend that Edmunds (or The Drive for that matter) are either. Edmunds ran what appears to be a not very scientific test, and came to a highly debatable conclusion that Tesla vehicles don't meet the EPA mileage guidelines. I think the tests are not comparable. Maybe that's just me.
