21 MPG combined isn’t going to win any hypermiling competitions, but in the world of high-performance luxury sedans, the 2016 Porsche Panamera S with the 3.0L V6 holds its own. This car is designed for effortless cross-country cruising and exhilarating backroad blasts, and fuel economy is often a secondary consideration for its clientele.

City and highway performance

The EPA estimates for the 2016 Panamera S are 18 MPG in the city and 26 MPG on the highway. Expect the city figure to reflect the demands of stop-and-go traffic, where the engine’s power and the car’s weight inevitably take their toll. The highway figure, however, demonstrates the efficiency potential of the V6 when cruising at a steady speed.

The seven-speed automatic transmission (AM-S7) plays a key role here, offering smooth shifts and helping to keep the engine in its optimal rev range for efficiency. The relatively high highway MPG is partly due to the tall gearing, intended to enable quiet and fuel-efficient long-distance driving.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2016 Porsche Panamera S is estimated at $2,750. This figure is based on driving 15,000 miles per year and using national average fuel prices. If you primarily drive in the city, or if fuel prices in your area are significantly higher than the national average, your actual fuel costs could be substantially higher than this number. Owners who primarily take long highway trips and drive fewer miles annually may see a lower fuel bill.

Real-world expectations

While EPA estimates provide a useful benchmark, real-world fuel economy always varies. The Panamera S, in particular, is a car that begs enthusiasm when driven, and enthusiastic driving rarely translates into optimal fuel economy. Owners who frequently tap into the engine’s considerable power reserves will likely see numbers closer to the city rating, especially during short trips. However, drivers who prioritize a smooth, even pace and take advantage of the car’s cruise control on highway journeys should be able to approach the stated highway MPG. Driving style, tire pressure, and even the grade of fuel used can all impact the final numbers.

How it compares

Compared to its rivals, the 2016 Porsche Panamera S sits roughly in the middle of the pack for fuel economy. The BMW 535i, with its 3.0L inline-six, manages a similar 20 MPG combined. The Mercedes-Benz E400, also with a 3.0L V6, posts 23 MPG combined. Some drivers might cross shop the Audi A7 TDI, which achieves 29 MPG combined thanks to its diesel engine. Then there’s the powerful Mercedes-AMG CLS63 S which only gets 18 MPG combined. The choice between these vehicles often boils down to priorities. The Panamera S buyer isn’t solely focused on squeezing every last mile from a gallon; they are looking for a blend of performance, luxury, and driving experience.

Tips to maximize efficiency

Use the Panamera’s driving modes. Selecting “Normal” or “Eco” will reduce throttle response and optimize the transmission for fuel efficiency. Sport and Sport Plus modes are better for performance, delivering the most enthusiastic driving, but using them will negatively impact fuel consumption.

Regular maintenance is critical. Keeping the engine properly tuned, ensuring that the tires are correctly inflated, and using the recommended grade of motor oil all contribute to optimal fuel efficiency. Neglecting these basic maintenance tasks can gradually degrade fuel economy over time.

Avoid unnecessary idling. Modern engines are designed to be efficient even at startup. If you anticipate being stopped for more than a minute, it’s generally more fuel-efficient to turn off the engine. Auto Stop/Start systems automatically do this, and getting in a habit of switching the ignition off can help in some situations.

Drive smoothly and anticipate traffic flow. Avoid sudden acceleration and braking, as these actions consume considerably more fuel. By maintaining a consistent speed and anticipating changes in traffic, you can minimize wasted energy and improve your overall fuel economy.

Consider using cruise control on the highway. Maintaining a consistent speed is crucial for fuel efficiency, and cruise control helps prevent unintentional speeding or fluctuations in throttle input. Using cruise control on long highway drives can allow the engine to operate at it’s most efficient speed. You can research all Porsche fuel economy data to see how other models compare.
