Welcome to the Tesla EPA spec on range. Its rated at ideal conditions. Say 45-50mph continuous, outside temp 75-85 degs, no AC or Heat.
Now take your Tesla on a real world highway run. Go 80mph, run heat or A/C, have some headwinds, maybe some hills (not mountains). You will lose 25%-30% of that 330 spec (318 with 20" wheels). Hello Tesla marketing. Any Tesla owner that has done a 250 mile drive with these conditions learns what to expect.
On the other hand, Audi, VW, GM, and Ford rate on typical driving. The meet or exceed their range. A competitor car at 285 rated range will beat a Tesla with 330 range spec at 80mph and conditions I noted. Beat, I mean how far to zero battery. Often times a 260 rated range will beat it too.
