The 2024 Porsche Panamera with its 2.9L six-cylinder engine gets 21 MPG combined. To be clear, Panamera buyers aren’t prioritizing fuel efficiency like a Prius owner. They are after blistering performance, impeccable handling, and the status of the Porsche brand. Fuel economy is a secondary consideration, a necessary trade-off for enjoying a sports car with four doors.

City and highway performance

The EPA estimates 18 MPG in the city and 25 MPG on the highway for this Panamera. The city figure reflects urban driving conditions where the engine frequently idles or accelerates from a stop. The highway rating is more optimistic, because consistent speeds on open roads allow the engine to operate more efficiently. Remember though that the Panamera invites spirited driving, and frequent acceleration will quickly reduce those highway mileage gains.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Porsche Panamera 2.9L at $2,750. This calculation assumes 15,000 miles driven annually and uses the national average fuel price during the EPA’s testing. This is only an estimate. Your actual fuel costs will vary based on your driving habits, fuel type, and location, as gas prices change significantly.

Real-world expectations

While the EPA provides a standard, real-world fuel economy often differs. Panamera drivers in urban areas might see numbers closer to the city rating, possibly lower with aggressive driving. Drivers who primarily commute on highways, and are careful with the throttle, might achieve figures closer to the EPA’s highway rating, but exceeding it would be difficult. Most Panamera owners value performance over saving gas, so achieving EPA estimates requires effort.

How it compares

The Panamera’s fuel economy places it among similar powerful and luxurious vehicles. The BMW M5, for example, gets 17 MPG city and 25 MPG highway. The Mercedes-AMG GT 4-Door Coupe performs similarly, around 16 MPG city and 24 MPG highway, and some versions get even less. The Audi RS7, which offers similar thrills and practicality, achieves a slightly better 15 city and 22 highway. These differences are noticeable on paper, but aren’t likely the deciding factor for buyers. They are purchasing a specific driving experience, and fuel is a known cost. For those seeking better efficiency, hybrid Panamera versions offer a blend of performance and better fuel economy. Porsche fuel economy data can be found here.

Tips to maximize efficiency

Intelligently use the Panamera’s drive modes. The “Normal” or “Eco” mode softens throttle response and optimizes the transmission for fuel efficiency. Avoid often using “Sport” or “Sport Plus” unless you’re using the car’s full performance.

Pay attention to tire pressure. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressures regularly and inflate them to the recommended levels on the door jamb sticker.

Avoid excessive idling. If you’re stopped for more than a minute, turn off the engine. Modern engines restart quickly, and idling wastes fuel.

Drive smoothly and anticipate traffic flow. Avoid sudden acceleration and hard braking, which waste fuel. Maintaining a consistent speed and anticipating traffic will improve your fuel economy.

Consider the hybrid Panamera models if lower fuel costs are a higher priority. They improve efficiency without sacrificing too much performance, providing a good compromise. You can also review PANAMERA MPG across all years to see how different engine and powertrain options affect fuel economy.
