19 MPG combined isn’t going to win any fuel-sipping awards, but the 2022 Porsche Panamera 4 Executive isn’t about sipping. It’s about effortlessly devouring autobahn miles while cocooning its occupants in supreme comfort and understated luxury. This isn’t your average grocery-getter; it’s a four-door grand tourer designed for executives who view driving as an experience, not a chore, and are willing to pay a premium at the pump for the privilege.

City and highway performance

The EPA estimates 17 MPG in the city and 23 MPG on the highway for the Panamera 4 Executive. These figures reflect the demands placed on its 2.9-liter twin-turbo V6. In urban environments, stop-and-go traffic prevents the engine from settling into its most efficient range, and the car’s substantial weight requires more energy to accelerate.

However, on the open road, the eight-speed automatic transmission (AM-S8) allows the engine to cruise at lower RPMs, contributing to the improved highway rating. Aggressive driving, almost encouraged by the Panamera’s responsive throttle and precise handling, will naturally depress both city and highway numbers, so restraint is key if you’re aiming for the EPA estimates.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2022 Porsche Panamera 4 Executive at $3,050. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that premium fuel is required for optimal performance and longevity of the engine, increasing the cost per gallon and, consequently, the annual expenditure.

Individual driving habits, traffic conditions, and fuel prices in your area will affect your actual annual fuel cost. Drivers who frequently engage the Sport or Sport Plus driving modes will see a significant rise in this number.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy often differs. Owners of the Panamera 4 Executive report numbers that vary based on driving style and environment. Some drivers focusing on efficiency have seen figures closer to the highway rating, while others who enjoy the car’s performance capabilities consistently fall short of the combined EPA estimate.

A realistic expectation for mixed driving is likely to be in the 17-21 MPG range. Factors like tire pressure, ambient temperature, and the use of accessories, such as air conditioning, can also influence fuel consumption. See PANAMERA MPG across all years for owner-submitted fuel economy data.

How it compares

The Porsche Panamera 4 Executive doesn’t exist in a vacuum. Competitors like the BMW 740i achieve around 25 MPG combined, offering a significant advantage. The Mercedes-Benz S500 earns about 24 MPG combined, and the Audi A8 manages 22 MPG, highlighting the Panamera’s relative thirst.

However, buyers considering a Panamera often prioritize driving dynamics and brand cachet over outright fuel efficiency. The Panamera delivers a distinct Porsche driving experience that these competitors, while refined in their own right, simply can’t match. While the EPA rating is lower, the Panamera provides a unique blend of performance and luxury that justifies the trade-off for many buyers.

Tips to maximize efficiency

The Panamera 4 Executive rewards smooth, deliberate inputs. Avoid aggressive acceleration and hard braking whenever possible. Anticipate traffic flow and maintain a consistent speed to minimize fuel consumption. Using cruise control on the highway can also help to improve fuel efficiency.

Select the “Normal” or “Comfort” driving mode for everyday driving. These modes prioritize fuel efficiency by optimizing throttle response, shift points, and suspension settings. While the “Sport” and “Sport Plus” modes unleash the car’s full potential, they significantly impact fuel consumption.

Regular maintenance is critical for optimizing fuel economy. Ensure that the tires are properly inflated to the recommended pressure, and schedule routine engine tune-ups. Replace air filters and spark plugs as needed to maintain optimal engine performance.

Reduce unnecessary weight in the vehicle. Removing heavy items from the trunk can improve fuel efficiency, especially in city driving. Avoid carrying extra cargo that is not needed for your journey. A cleaner, lighter car will always use less gas.

Consider using the Auto Start/Stop function. It can save fuel in stop-and-go traffic, but its effectiveness depends on driving patterns. If you frequently experience short stops, disabling the function may be preferable. In long traffic jams, however, allowing the engine to shut off can result in noticeable fuel savings.
