I have read other Tahoe trip reports - so this is just a few points that I thought was worth sharing. From south bay (San jose) to North Tahoe (squaw valley) was 240miles each way. Family trip (2 adults, 2 kids) and decent luggage for 2nights/3-days. Charged car to 90% from home (7,000ft climb in the last 70 miles of the trip). Had turned on the "range mode" in the car - and kept the AC ON the whole time, temp set to 72deg - wife doesn't like it cold. The Car did a pretty decent 335watts/mile - considering the climb - pre-climb, it was 288wpm, the climbing section was more like 430wpm I think - with one supercharging at Rocklin (that was super fast BTW - 20mins got me 100+miles, quite a busy supercharger, next to SC), and then I topped off at Truckee (behind Safeway, kind of shady corner, was not busy at all)- just in case the destination charging didn't work. I was not really keeping up with the recommended speeds (< 70Mph) - I went similar to other cars' speeds. Destination charging at Resort at Squaw Creek is fantastic - there are 3 chargers (16KW) just behind the main building (closer to your room), so you can get back and forth between car & room if you like (access from 2nd floor). The other 3 chargers are at the regular (far) parking lot (quite full, and cars are parked close to each other). Note: Destination charging isn't free - it is part of Valet service ($35/night) :-(. So you may want to valet on the last night of your trip to fully charge before taking off (or use Truckee supercharger - barely 10miles from the resort). Next time, I may not do valet. BTW, Valet kept the keys, but the app was quite useful to access the car without going to bell desk. On the way back, I did get pretty low watts/mile. Had charged to 95% before starting return journey (destination charging). Total 500mile trip averaged out to be exactly 290Watts/mile. I was quite amazed - very close to rated miles for the 75D. I think the dual motors do a fantastic job with efficiency, even with the speeds I was going at. I did not drive at 65Mph. I went with the regular speeds that other cars drove. The highway 5 segment was 70mph speed limit and many cars were going at 79Mph. There was no snow on the road - that could have helped with efficiency too. The return journey (240miles) - car said I would reach home with 6% remaining without any supercharging - and it was quite accurate. Even though, the car did remind me (on both the screens to keep speed to 65Mph to reach destination) - the higher speeds didn't seem to burn the battery down any faster than what the system predicted at the beginning. I never the less did a 15min supercharge at the fremont factory supercharger facility - don't like the car to run that low when reaching home (man - that was backed up 6cars when I left). Really liked the real-time monitoring of the supercharger usage through the Nav - was very helpful when I had to select between two supercharger options close-by. autopilot: the stretch of I-80 climbing up/down in winding roads - I used TACC instead of AP as AP1 sometimes didn't find lanes (there were none actually in some stretches because of heavy snow season wear & tear I think) - TACC itself is really useful. Driver just has to remember that they are on TACC and not AP - I know it is easy to figure out by looking at the blue circles, just need to be mindful. AP worked great on well marked highways - which was most of my journey (no truck lust or anything). Slacker worked fine all the time - no LTE signal issues anywhere during the drive or at Squaw valley. the trunk space is enormous for a sedan (is MS a sedan or a hatchback by definition?). The back seats headrests are rather more protruding (we have premium seats) - wasn't quite comfortable for long drives for adults I would think - adjustable headrests for back would have been good. All in all - quite impressed with our first long journey that required a supercharger. And the latest Tesla blog on more superchargers only increased our confidence to go out more often with the MS. We are new to this - and I have read many cross-country reports here at TMC, all it takes is a drive or two ourselves to bring all that together.
