BREAKING: Tesla Model 3 Gets Official EPA Range Rating Of 310 Miles Combined, 322 City City range is 321.9 miles and highway range is 295.5 miles. 310 miles combined. Also of note: This would mean the battery holds 80.5 kWh of energy. (I assume that's gross capacity, not nominal.) The 150 Wh/kg is interesting too, since it's at the pack level. It's a bit lower than I suspected it might be.
