Warmest day of the year here in Philly suburbs. 75-78 degree temps. Drove mostly highways at 70 on cruise control. Took a trip of almost 3 hours (about 180 miles). Minimal AC temp set at 70 interior. No cooling on seats. On smooth drive mode high regen. 19 inch wheels at 50psi. Got the highest rating I ever got: 4.0miles/kwh. In the dead of winter I would get barely 3.0miles/kwh.
