Plenty of reviews on this car, but not a ton of coverage on P3D and especially for the P3D+ (namely 20" 4S wheels), so thought it might be helpful for those undecided. After an 800-mile trip from AZ to CA and back in 2 days, using 99% autopilot @ limit+5mph (65/70-75/80), I averaged 300 Watt/mile. This of course translates to 250 mile range. I don't do a lot of long distance driving, so this wasn't a big deal to me, but wanted to provide some insight on real-world driving range. Tires were at 46 PSI (i'll drop down a bit now that trip is over). I've seen enough data to not expect to see the 310 EPA range, but I was a little disappointed after doing mostly everything right. Now the impact of the reduced range wasn't a huge deal. I don't believe I would have stopped any less if I had the full 310m range, but it did impact: Estimated routes are based on this EPA range could get people into trouble. Think about it. Sometimes, Tesla will route you to a destination with an estimated 10% range remaining. Well, as shown from my data, my vehicle gets about 20% less range than the estimates. Luckily this didn't impact me, but it could have. My biggest pet peeve is that the estimates are based on EPA, not real-world usage. It seemed to improve over time, but I cannot say for certain. Even though I didn't stop any more frequently, with my vehicle being less efficient, it resulted in roughly 20% longer stops due to increased charge times. Not a huge deal, most superchargers are reasonably strategically located to useful stuff. Overall a great experience, and have zero regrets with P3D+. But if you do a lot of long range trips, this may be a consideration. Perhaps they'll release 20" aero's in the future to improve range by ~5%.
