My 90D showing a range of 291 miles at 90% charge. Either I got a secret 100kw upgrade or the car is a bit overconfident about itself. On another note, our family traveled from San Diego to Los Angeles today in an ideal condition. The car consumed about 345 watts per mile for total of 45 Kw (much better than my normal consumption of 375w/mile). However, 45 kw also comprised 60% of the capacity per car display (going from 90% to 30%). This means that my X 90D battery capacity would be about 75kw according to the calculations made by the car itself. Since the car only calculates estimations, I do not know what to make of these numbers, but needless to say it makes planning for longer trips a little more nerve-racking.
