Ways to spend less

  • Ask your utility about a time-of-use or EV rate and schedule charging for off-peak hours; the car or charger can do it automatically.
  • Precondition the cabin while the car is still plugged in, so heating or cooling comes from the grid instead of the battery.
  • Keep tires at the pressure on the door-jamb sticker; underinflated tires raise consumption.
  • Drive 100 fewer miles a month: saves $4.04 at 14.4¢ per kWh.
