The 2019 Porsche Panamera 4S Executive gets 21 MPG combined. This long-wheelbase Panamera variant isn’t about hypermiling. It delivers effortless autobahn cruising, surprisingly engaging handling for its size, and the status of the Porsche crest. Fuel economy is a consideration, but not the main reason to buy it.

City and highway performance

Breaking down the 21 MPG combined figure, the Panamera 4S Executive achieves 18 MPG in the city and 26 MPG on the highway. The city figure is more relevant here because while this car may be used for continental tours, many owners will navigate crowded urban environments daily. The responsive 2.9L twin-turbo V6 consumes more fuel when repeatedly accelerating and navigating gridlock. The highway figure is respectable, allowing for comfortable and relatively efficient long-distance travel, but aggressive driving will quickly reduce that 26 MPG rating.

Annual fuel cost

The EPA estimates a $2,750 annual fuel cost for the 2019 Porsche Panamera 4S Executive. This is based on driving 15,000 miles per year (55% city, 45% highway) using national average fuel prices. Premium fuel is required, increasing the cost of ownership. While the $2,750 estimate is a useful benchmark, actual fuel costs depend on driving habits, road types, and gasoline prices. Heavy acceleration or excessive idle time will increase expenses.

Real-world expectations

While the EPA provides standardized testing, real-world fuel economy for the Panamera 4S Executive varies. Expect 18 to 24 MPG combined, depending on driving style and conditions. Sport or Sport Plus mode will result in numbers closer to the lower end of that range. Gentle driving, automatic start/stop, and coasting might approach the EPA’s 26 MPG highway estimate on longer trips. Passenger and cargo weight also affects fuel consumption, factors like tire pressure and weather conditions do as well.

How it compares

The 2019 Porsche Panamera 4S Executive’s fuel economy sits within a specific range compared to competitors. The Mercedes-Benz S560 gets 17 MPG combined. The BMW 750i xDrive returns around 20 MPG combined, while the Audi A8, with its V6, sometimes achieves slightly better fuel economy close to 22 MPG combined, but with slightly different performance. If maximizing MPGs is the top priority, consider plug-in hybrid options instead.

Tips to maximize efficiency

Use the Panamera’s driving modes effectively. Keeping the car in “Normal” mode for everyday driving will prioritize fuel efficiency by optimizing throttle response and transmission shift points, and suspension settings. Avoid “Sport” or “Sport Plus” modes unless extra performance is needed, as these modes increase fuel consumption.

Pay attention to tire pressure. Maintaining the recommended tire pressure improves handling and safety and reduces rolling resistance, improving fuel economy. Check tire pressure regularly, especially during temperature changes.

Anticipate traffic flow and avoid aggressive acceleration and braking. Smooth driving is key to maximizing fuel efficiency. Coasting to red lights and stop signs saves fuel.

Minimize idling. Modern engines are efficient, even at idle, but idling still consumes fuel. If stopped for more than a minute or two, turn off the engine. The Panamera’s automatic start/stop system helps in stop-and-go traffic.

Schedule regular maintenance. A well-maintained engine runs more efficiently. Ensure the air filter is clean, spark plugs are in good condition, and oil changes are performed according to the manufacturer’s recommendations. This achieves the best fuel economy.
