20 MPG combined. No one buys a 2023 Porsche Panamera 4 Sport Turismo with its 2.9L twin-turbo V6 expecting hybrid-rivalling fuel consumption. This car is about effortless power, striking design, and the unique combination of sports car driving dynamics with practical wagon versatility. The 20 MPG is simply the price of admission for that experience, a figure that is accepted, but likely not celebrated, by its clientele.

City and highway performance

The EPA estimates you’ll see around 18MPG in the city and 23MPG on the highway. While these figures might seem unremarkable on their own, consider what’s under the hood and how the Panamera is typically driven. The 2.9L V6, delivering a potent 348 horsepower, encourages enthusiastic acceleration, particularly around town. Resist the urge to fully unleash that power, and those city figures might increase. On the open road, the Panamera 4 Sport Turismo settles into a comfortable, yet still decidedly sporty, cruise. The eight-speed automatic transmission (AM-S8) helps optimize fuel economy at higher speeds, although sustained speeds above 80mph will bring the 23 MPG estimate down quickly.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Porsche Panamera 4 Sport Turismo at $2,900. This calculation is based on driving 15,000 miles per year, using a blend of city and highway driving, and assumes the national average price for premium fuel. Fuel prices fluctuate, and your actual costs will vary depending on your driving habits and where you live. This $2,900 figure provides a reasonable benchmark against which to compare other vehicles, even if a Panamera buyer is not especially price-sensitive.

Real-world expectations

While the EPA estimates provide a useful reference point, real-world fuel economy for the Panamera 4 Sport Turismo can vary significantly based on driving style and conditions. Frequent short trips, aggressive acceleration, and extended idling will all negatively impact fuel consumption. Prioritizing smoother acceleration, anticipating traffic flow, and maximizing highway cruising can help you get closer to, or even slightly exceed, the EPA estimates. The Panamera’s driving modes (Normal, Sport, Sport Plus) also influence fuel economy; sticking to “Normal” whenever possible will yield the best results.

How it compares

Compared to its competitors, the Panamera 4 Sport Turismo’s fuel economy is largely in line with expectations for a high-performance luxury wagon. The Mercedes-AMG E450 4MATIC Wagon, a similarly powerful and luxurious alternative, achieves around 22 MPG combined with its six-cylinder engine. Audi’s RS6 Avant, with its monstrous twin-turbo V8, offers supercar-like performance but pays the price with a considerably lower MPG figure in the high teens. The Taycan Sport Turismo, Porsche’s electric wagon, offers substantially better economy but lacks an internal combustion engine for those with range anxiety.

This comparison highlights that the Panamera 4 Sport Turismo strikes a balance between performance, practicality, and acceptable fuel consumption, even though there is no superlative MPG figure available.

Tips to maximize efficiency

Take advantage of the Panamera’s automatic start/stop system. Some drivers find these systems intrusive, they can contribute to noticeable fuel savings over time, especially in stop-and-go city traffic. The system can be deactivated through the center console if desired, but consider leaving it on, at least some of the time.

Ensure your tires are properly inflated. Underinflated tires create more rolling resistance, which forces the engine to work harder and reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended levels listed on the doorjamb sticker.

Use cruise control on the highway. Maintaining a constant speed helps optimize fuel efficiency on long highway drives. Cruise control minimizes unnecessary speed fluctuations, which can otherwise occur with pedal inputs alone, leading to better MPG.

Lighten the load. Carrying unnecessary weight in your car reduces fuel efficiency. Remove any items from the trunk or rear seats that you don’t need on a regular basis. A lighter vehicle requires less energy to accelerate and maintain speed.
