2021 Porsche Fuel Economy
EPA rated 6 Porsche models for 2021. Each model page lists every trim's city, highway and combined figure and works the rating into a cost per mile at a price and mileage you set.
Models
| Model | Trims | Combined, lowest to highest trim |
|---|---|---|
| 718 | 20 | 19–24 MPG |
| 911 | 19 | 17–21 MPG |
| Cayenne · plug-in | 12 | 17–21 MPG |
| Macan | 4 | 19–21 MPG |
| Panamera · plug-in | 21 | 17–22 MPG |
| Taycan · plug-in | 10 | 70–79 MPGe |
Combined is EPA's 55% city / 45% highway blend. Electric and plug-in models show MPGe, gasoline-equivalent miles per gallon; their pages carry the kWh per 100 miles that charging cost actually turns on.
