20 MPG combined is what owners of the 2023 Porsche Panamera 4 are actually getting. Buyers drawn to the Panamera 4 aren’t looking for Prius-level efficiency. They’re accepting a trade-off: exhilarating performance and Porsche DNA in a four-door package, knowing that fuel economy is between a sports car and a family sedan. This isn’t about miles per gallon, it’s about driving pleasure with some practicality.

City and highway performance

The Panamera 4’s EPA ratings of 18 MPG in the city and 24 MPG on the highway reflect its performance. The city figure reflects the stop-and-go nature of urban driving, where the 2.9L twin-turbo V6 is often used to accelerate. The highway number, while respectable, isn’t great. Still, it allows for long-distance cruising without constant fuel stops, which is essential for a grand tourer aspiring to cover vast distances quickly.

Annual fuel cost

The EPA estimates that owning a 2023 Porsche Panamera 4 will cost approximately $2,900 per year in fuel. This is based on driving 15,000 miles annually, with a mix of city and highway driving, using the national average fuel price. This number will change depending on driving habits and fuel costs in your area. More aggressive driving, especially frequent use of Sport or Sport Plus modes, will increase how much you spend per year. Consider it the cost to have the Porsche experience.

Real-world expectations

What are Panamera 4 drivers actually seeing, not just the EPA estimates? Expect figures around the stated numbers, but be prepared for some variation. An aggressive driving style will easily drop you below 18 MPG in the city, while trying to maintain consistent speeds on the highway might nudge you closer to 26 MPG. Weather, tire pressure, and even the type of gasoline can influence your fuel consumption. Premium fuel is recommended, and typically required for optimal performance.

How it compares

The Panamera 4’s fuel economy is competitive among performance sedans. The BMW M550i xDrive, with its 4.4L V8, manages approximately 17 MPG city and 25 MPG highway. A Mercedes-AMG E53 sedan achieves similar figures of around 22 MPG combined. The Audi S7 is a bit better with around 22 MPG combined and a 2.9L turbocharged V6 engine.

All these vehicles demand premium fuel, adding to the cost of ownership. The Panamera 4 buyer is likely cross-shopping these models, weighing performance, luxury, and fuel consumption.

Tips to maximize efficiency

Don’t floor the accelerator every chance you get. The Panamera 4 has a lot of power, but using it costs you gas. Smooth acceleration and knowing the traffic flow will reduce fuel consumption without sacrificing too much driving fun. Use the “Normal” driving mode when commuting and save the more aggressive modes for spirited driving.

Ensure your tires are properly inflated. Porsche specifies tire pressures for comfort and efficiency. Maintaining these pressures reduces rolling resistance, leading to better fuel economy. Regularly check your tire pressure and adjust accordingly, especially when the temperature changes.

Don’t idle. Letting the engine run while stationary consumes fuel and produces emissions. Turn off the engine if you expect to be waiting, such as waiting for someone or sitting in a parking lot. Modern engines warm up quickly while driving, so idling is generally unnecessary.

Consider using the coasting function, which is available on some Panamera models, when appropriate. Lifting off the accelerator, allowing the car to coast without engine braking, can conserve fuel, especially on downhill stretches. This takes practice, but it can save fuel.

Keep your Panamera 4 maintained. Regular servicing, including oil changes, air filter replacements, and spark plug maintenance, ensures that the engine works efficiently. A well-maintained engine consumes less fuel and performs better, lengthening the life of the vehicle.
