In addition to the entertainment system, lights, AC/heater the passenger and their weight will impact range. Cargo may also vary range depending on what one can squeeze into the trunk.
WhiteStar range will have even more variations. My semi-monthly drive from Westchester, NY to Brooklyn is ~ 55 miles. Add in the wife, two kids, dog and a trunk full of "stuff". Making it back home with "half a tank" would be stunning
