Greetings! So, I just finished a ~2600 mile road trip in my X P100D, mostly up and down I-95 on the east coast. I went from my home in NC to Orlando, FL, back home, then to NJ, then home again, plus some in-town driving at each place. Three people plus a minor amount of luggage... nothing too crazy. No trailer or anything either. Weather was very good for all but the first day of the trip where it was colder (~40F) with a little bit of rain here and there. Other than that was generally between 55F and 80F with clear skies. The majority of the trip was done with range mode on, sport mode acceleration profile (ie, ludicrous disabled). Normal highway speeds ranging from ~55 to ~75 MPH. My trip meter since leaving home: Now, a rated mile in the X P100D, according to the car, is 342 Wh/mi... however I've never been able to hit this in practice under normal conditions. But 460/342 = 134.5% of rated energy usage.... which seems a bit excessive to me. I tried twice on Florida afternoons when it was ~70F on flat roads to cruise at a steady 65 MPH with the HVAC off to see if this made any difference in efficiency. The best I was able to get over a 15 mile stretch was about 380 Wh/mi... and I'm pretty sure some of that gain was tail wind. The trip planner was also consistently wrong about the amount of energy needed to reach the next charger, usually by roughly 10%. I would charge until it said maybe 15% charge at my destination, start driving, and 10 miles down the road it'd have adjusted to 4-5% and complain about "Drive 60 MPH to reach your destination" or whatever... I also had a script I made running on the CID monitoring HVAC power usage at times. Last time I complained to Tesla about power usage they blamed it on the X having two PTC heaters and the winter cold at the time (December). However, even on the coldest part of the drive, where both PTC heaters were running for a bit to hold ~68F inside, HVAC power usage only accounted for about 6% of total consumption... not enough to account for the huge difference vs rated efficiency. Now, admittedly, this is the only X I've driven longer distances with. I've driven tens of thousands of miles in the S's, however, and even with a very lead foot I would maybe get 20% usage over rated... but usually around 10% over rated efficiency when driving normally with traffic. With the X, even when I'm trying to drive conservatively with the flow of traffic I can't get anywhere near rated... heck, +20% would even be great. Long story short, I'm trying to see what others get under normal conditions in their X's. Preferably some numbers from P variant longer trips. I've noted my numbers to Tesla and have an appointment scheduled for next week. Would be great to have some data that helps confirm I'm not crazy and that my car is abnormally inefficient. I'd figure if this were normal for the X there would be more outrage, but I haven't really seen any... which leads me to believe it's just something with my car. Random note: They recently did an alignment and 4-wheel balance on my X before my trip. My X charges to 289 rated miles with the 100 pack... however charging to near 100% and heading out I can barely do 200 real miles still, which is disappointing. Also, the 100 pack maintains higher power levels during supercharging vs the 85/90 packs, but most of that benefit seems to be negated for me since the car is using 35% more energy than it should be... so I still ended up needing to spend a lot of time at chargers in the taper area of the curve when I feel like that shouldn't have been needed at all with the larger pack. I estimate I spent a good 3 hours extra at superchargers through the whole trip because of the inefficiency vs expected. Anyway, aside from this and the Columbia, SC supercharger being 100% ICEd when I got there, this road trip was still fun, but would like the next one to be better if possible.
