20 MPG combined. Those three little characters represent the fuel economy of the 2022 Porsche Panamera. It’s a number that acknowledges other drivers on the road while still delivering performance. This isn’t a car for those whose primary concern is fuel efficiency. It’s for those seeking a visceral driving experience wrapped in a luxurious and incredibly capable package. The Panamera is a statement, and that statement says performance comes first, even if it means slightly more frequent trips to the pump.

City and highway performance

The official EPA figures for the 2022 Porsche Panamera equipped with the 2.9L twin-turbo V6 and 8-speed automatic transmission (AM-S8) are 18 MPG in the city and 24 MPG on the highway. This variance speaks to the nature of the car. In urban environments, its weight and performance-oriented tuning will naturally lead to lower fuel economy. Out on the open road, however, the Panamera’s drivetrain can stretch each gallon further, especially at consistent cruising speeds. The eight-speed transmission plays a crucial role here. It offers taller gears that allow the engine to operate at lower RPMs at highway speeds, contributing to the more respectable 24 MPG highway rating. Driving style has a large impact, as a heavy right foot can erase any potential gains.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2022 Porsche Panamera 2.9L is $2,900. This figure is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation. Keep in mind, premium fuel is required, so that average fuel price is significantly higher than regular unleaded. This $2,900 figure provides a reasonable benchmark for budgeting, but individual fuel costs will vary considerably depending on driving habits, location, and fluctuating fuel prices. Someone who spends most of their time in stop-and-go traffic in Los Angeles should plan for a noticeably higher fuel bill than someone who primarily uses the Panamera for long highway stretches in a rural area.

Real-world expectations

While the EPA estimates provide a standardized baseline, real-world fuel economy often deviates. Panamera owners should adjust their expectations and understand that achieving the stated figures requires a conscious effort in driving conservatively. Aggressive acceleration, frequent hard braking, and extended idling can all significantly reduce fuel efficiency. Owners report averaging around 17-22 MPG in mixed driving conditions, which falls close to the EPA’s estimates. However, those who frequently use the Panamera’s sport modes and exploit its performance capabilities will likely see numbers closer to the lower end of that range.

How it compares

In the realm of luxury performance sedans, the Panamera’s fuel economy is neither exceptional nor dismal. Consider its direct rivals. The BMW M5, for example, is rated at 17 MPG combined. The Mercedes-AMG E63 S manages a similar 19 MPG combined. Even the more comfort-oriented Audi S7 comes in at 22 MPG combined. While the Audi edges out the Panamera, these numbers highlight that high-performance and fuel efficiency are often at odds. Buyers in this segment are typically more concerned with power, handling, and luxury than squeezing every last mile from a gallon of gasoline. They accept the trade-off as the cost of admission for owning a vehicle that delivers this level of performance and prestige.

Tips to maximize efficiency

Optimize tire pressure. The Panamera’s performance depends on having properly inflated tires. Underinflated tires increase rolling resistance, which negatively affects fuel economy. Check the sticker on the driver’s side doorjamb for the recommended pressure and maintain it consistently.

Use cruise control on the highway. Maintaining a steady speed minimizes unnecessary acceleration and deceleration, resulting in better fuel economy. The Panamera’s adaptive cruise control system can further enhance efficiency by automatically adjusting speed to maintain a safe following distance.

Resist the urge for aggressive acceleration. The twin-turbo V6 is tempting, but every full-throttle launch guzzles fuel. Smooth and gradual acceleration will conserve fuel and also preserve tire life.

Minimize idling. Modern engines are designed to be efficient when running, but idling consumes fuel without covering any distance. If you anticipate being stopped for more than a minute, turn off the engine.

Consider the driving mode. The Panamera offers various driving modes, including “Normal” or “Eco,” which optimize fuel economy by adjusting throttle response and transmission settings. It’s worth using these modes during regular commuting to slightly boost your MPG.
