19 MPG combined is a figure that will likely register somewhere between “acceptable” and “irrelevant” for the buyer of the 2023 Porsche Panamera 4S Executive. This isn’t a car purchased for its fuel consumption. It’s a long-wheelbase grand tourer engineered for speed and comfort, primarily for those who prioritize arriving refreshed and relaxed, even if it means a slightly larger fuel bill.

City and highway performance

The EPA estimates 17 MPG in city driving and 23 MPG on the highway for the Panamera 4S Executive. The low city figure reflects stop-and-go traffic and the engine’s willingness to exploit its 443 horsepower. The highway number, while not stellar, is more respectable, hinting at the turbocharged V6’s ability to cruise efficiently at higher speeds, particularly when the adaptive cruise control is engaged and the eight-speed automatic transmission settles into its tallest gear. These numbers reflect consistent driving habits. For a more complete picture, check out PANAMERA MPG across all years.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Porsche Panamera 4S Executive at $3,050. This figure is calculated based on driving 15,000 miles per year and using national average fuel prices for premium gasoline, which this car requires. It’s a benchmark, of course, and your actual costs will vary based on your driving habits, the price of fuel in your area, and the number of miles you actually drive.

Real-world expectations

While the EPA provides a standardized test, real-world fuel economy often differs, and that’s especially true with a car like the Panamera 4S Executive. Driven with restraint on the highway, exceeding the EPA’s 23 MPG estimate is possible, with some drivers reporting figures in the high 20s. However, indulging in the car’s performance capabilities will inevitably lead to a decrease, potentially dropping into the low teens in spirited driving or dense urban environments. Your right foot largely dictates the fuel economy you will achieve.

How it compares

The Panamera 4S Executive’s fuel economy positions it in a specific spot. The Mercedes-Benz S 500, for example, achieves an EPA-estimated 21 MPG combined, slightly better than the Panamera while offering a similar level of luxury and performance. A BMW 740i gets 25 MPG combined, a sizable MPG increase from the Panamera. Buyers cross-shopping these cars may find the Mercedes and BWM to be more practical choices. Understanding how these cars measure up against each other can help paint a more accurate picture when factoring in overall cost of ownership. You can easily compare all Porsche fuel economy data by model and engine type.

Tips to maximize efficiency

Take advantage of the Panamera’s driving modes. Selecting “Normal” or even “Eco” mode will noticeably soften throttle response and encourage earlier upshifts, helping to conserve fuel during everyday driving. While the temptation to unleash the engine’s full potential is always present, resisting that urge when commuting or performing routine errands can make a difference.

Maintain proper tire inflation. Check your tire pressures regularly and ensure they are inflated to the manufacturer’s recommended specifications, which can be found on a sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. This is a simple task that can yield measurable benefits.

Reduce unnecessary weight. Carrying excess weight in the vehicle requires the engine to work harder, consuming more fuel. Remove any unnecessary items from the trunk and rear seats. Even small amounts of extra weight can contribute to a decrease in fuel economy over time.

Avoid aggressive driving habits. Rapid acceleration, hard braking, and high-speed cornering all consume significantly more fuel. Smooth, consistent driving and anticipating traffic flow will not only improve fuel economy but also contribute to a more relaxed and enjoyable driving experience. The Panamera is capable of incredible feats of performance, so take care to temper enthusiasm in normal driving situations.
