I think the range is very optimistic. While energy graph was available I played with it a little bit - the best I could do was 350Wh/mi while seriously trying to be gentle. Anything more 'spirited' would jump to 450-600 range. I noticed that if I make short trips my battery charge will drop by 1-2% every time within first minutes of driving. I assume some sort of preconditioning is going on and it sucks juice out of the battery. If I compare to MY LR - MX Plaid is very thirsty. My expectations were "a little bit more" thirsty but that is not the case. Since removal of "energy" I have no idea about the consumption but I am charging it a lot more than MY.
I highly recommend people not consider the "rated range" (EPA or otherwise) for the OP's situation. It's not about range, it's about battery capacity.
It's easy to calculate the battery capacity, based on reported % SOC at two time points, the distance driven between those two time points (the longer the better), and the average consumption (Wh/mi) between those two time points (best to reset one of the trip computer's trips for this). So do a drive and collect these data:
SOC1 = battery % charge at start of drive.
SOC2 = % charge at end of drive
D12 = distance driven (cars drive upwards of 3 miles per percent, so the longer your trip, the more accurate your result will be.)
CONS12 = average consumption/economy during trip, in Wh/mi
Then TRIP% = SOC1-SOC2
TRIP_ENRG = (CONS12/D12)
And,
BATT_SIZE = TRIP_ENRG / (TRIP%/100)
OP gathered these exact data. They drove 180mi, and had a change in SOC of 70%, and during that trip they averaged 331 Wh/mi.
331 Wh/mi * 180mi = 59,580 Wh of energy, or rounding off, 59.6kWh.
That 59.6kWh of energy resulted in a 70% drop in battery SOC. So,
59.6kWh / 0.70 = 85.1 kWh total expected battery capacity.
This is way off from what the X-Plaid should have; it should have somewhere in the neighborhood of 95kWh to 100kWh expected full battery capacity.
You can do this kind of experiment on any Tesla car, and drive as hard as you want, into wind, up hills, with 22" wheels, or 19's, etc., it doesn't matter. So long as you aren't peeling out for large portions of this test drive (wheels slipping on pavement), you should get an expected/predicted full capacity that is in the ball park of your battery's reported size (if your car is relatively new).
OP's battery is very new. They should be getting something well above 90kWh predicted battery size based on a trip's data.
I really think OP,
@akahitek you should complain and ask for a full battery diagnostic test, and ask to get a copy of the results.
If you make the mistake of saying "I'm not getting the range I think I should be getting" then they will just tell you you're driving harder than you should, or your wheels are too big, or maybe it was cold that day and windy, etc. If you say "I don't think my battery has the capacity it's supposed to have" that will result in a more technical discussion, and investigation of your battery's health.
In addition, or alternatively, you can go to
'scan my tesla' is an Android app that will connect to a Tesla Model S, 3, X and Y CAN bus, and show and log hundreds of readings. Please note you need a special wiring harness to connect, more details under Adapters. This app gives you numerous live statistics such as: - Battery power / voltage
www.scanmytesla.com
Buy one of their adapters and cables, and get your own battery health report. This is also handy for long-term tracking of your battery's capacity, which WILL go down with age.... just not as quickly as we're seeing with OP's Plaid X.
