Hello - I've been the owner of a Model X P100D for a month now. I was going to run a lot of errands last weekend and decided to charge the car to 100%. It stopped at 287 miles. I'm wondering if its normal to not get the full 289 mile reading on the battery when charged to 100%? On that same note, I'm currently with a Model S 100D loaner. The top range is 335 miles. Its as brand new as my car (500 miles only) and actually charges to 337 miles. This raised a bit of a concerned for me. Tesla said they are going to run some battery degradation tests on it and compare it to similar cars they have data on. Seems a little early if you ask me to be degrading right? I'm wondering what other owners are getting.
