20 MPG combined won’t impress hybrid shoppers, nor those prioritizing pure economy. But in the context of the 2022 Porsche Panamera 4S, a luxury performance sedan engineered for remarkable speed, handling, and driver engagement, it’s an acceptable tradeoff. The Panamera 4S is bought by those who value a finely-tuned engine and precise cornering more than maximizing fuel efficiency.

City and highway performance

The EPA estimates for the Panamera 4S equipped with the 2.9L twin-turbo V6 and 8-speed automatic transmission are 18 MPG in the city and 24 MPG on the highway. City driving always lowers fuel efficiency because of stop-and-go traffic and idling, but the Panamera’s engine management system and quick-shifting transmission help reduce fuel consumption somewhat. The highway figure of 24 MPG reflects relaxed, long-distance cruising, where the Panamera 4S is composed and comfortable, even at higher speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Porsche Panamera 4S at $2,900. This is based on driving 15,000 miles per year and using national average fuel prices for premium gasoline, which the Panamera 4S requires. This may seem high compared to more fuel-efficient vehicles, but remember that this cost is part of the experience of owning a high-performance luxury car. Panamera 4S owners often consider the expense part of ownership.

Real-world expectations

While the EPA estimates are a useful baseline, real-world fuel economy varies depending on driving style, traffic, and factors like weather. A driver who often uses the Panamera 4S’s performance will likely see figures below the EPA estimates. On the other hand, a driver who drives conservatively and spends much time on the highway might get results closer to, or even slightly better than, the EPA ratings. Understanding how your driving habits affect fuel consumption is key.

How it compares

Compared to other luxury performance sedans, the 2022 Panamera 4S’s fuel economy is normal for its class. The BMW M5, for example, is rated at 15 MPG city and 21 MPG highway, making the Panamera 4S slightly more economical. The Mercedes-AMG E53 Sedan achieves around 21 MPG combined. You can view all Porsche fuel economy data to see that Panamera models with less powerful engines, or hybrid powertrains, do much better on the MPG front. For example, the Panamera 4 E-Hybrid achieves a higher combined fuel economy thanks to its electric assistance. The decision depends on priorities. If performance and luxury are important, the Panamera 4S’s fuel consumption is an acceptable compromise. But if fuel economy is a primary concern, other models, including other versions of the PANAMERA MPG across all years lineup, may be better.

Tips to maximize efficiency

While the Panamera 4S focuses on performance, owners can still take steps to improve fuel economy. Smooth and gradual acceleration is crucial, using less engine power to build speed. Avoid aggressive starts and stops, as these use much more fuel.

Maintaining proper tire inflation is another important factor. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel efficiency. Check your tire pressures regularly and inflate them to the recommended levels listed on the door jamb.

The Panamera 4S has driving modes that affect fuel consumption. Selecting “Normal” or “Eco” mode can soften throttle response and optimize engine management for efficiency. While “Sport” and “Sport Plus” modes provide a more engaging driving experience, they also consume more fuel.

Finally, minimize unnecessary weight in the vehicle. Carrying extra cargo, especially heavy items, can negatively impact fuel economy. Remove any items from the trunk or rear seats that are not essential.
