Ways to spend less

- 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 $7.99 at 21.8¢ per kWh.
