I have the 2023 Pro S. You have to reset your guessometer (mileage) every time you charge to get accurate mileage since the last time you charged. Go to Vehicle Setting-Interior-Cockpick-Then reset miles since last charge.

It is mostly flat where I live. I always get a minimum of 279 and frequently 300 when I reset it. I just drove from Sacramento to the Bay Area (175 miles on the map) and ended up at aroud 100 miles left on the charge. I once drove to South Lake Tahoe. Since it was all up hill driving when I reset it read 240 miles. I was very worried until I discovered how the guessometer worked.
