Electricity versus gasoline
| Tesla Model 3 Standard RWD | Gas car | Difference | |
|---|---|---|---|
| Per 100 miles | $5.26 | $14.93 | $9.67 |
| A month (1,000 mi) | $52.59 | $149.33 | $96.75 |

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 $5.26 at 21.7¢ per kWh.
