I am new to this forum, having only recently taken possession of a new Long Range Model X (late 2020). I'm in the UK. I was expecting great things, but I am constantly disappointed.
For starters the quoted range (on the dash) is 333 miles at 95% charge. I have already done 1043 miles, and my average energy usage is 431 Wh/m. With a battery capacity of 95%, this equates to 95kW of the 100kW battery. At an energy usage of 431 Wh/m the actual range is only 220 miles and nowhere near 333 miles! I recently took a round trip journey to Heathrow of 214 miles, 107 miles each way. When I arrive at Terminal 5, my battery range had dropped from 333 miles to only 145 miles. This equates to a usage of 188 miles even though the actual mileage was only 107 miles. The range was therefore off by almost 30%, which is roughly consistent with the number I calculated above between expected full range and actual full range. How can Tesla justify saying this car has a 340 mile range!
