19 MPG combined is the fuel economy of the 2023 Porsche Panamera 4S Sport Turismo. Nobody buys a Panamera 4S ST for its fuel efficiency. This is a high-performance luxury wagon engineered for exhilarating driving, and the 2.9L twin-turbo V6 prioritizes power. For enthusiasts who value performance and practicality, that 19 MPG is the cost.

City and highway performance

The EPA estimates the Panamera 4S Sport Turismo will achieve 17 MPG in the city and 23 MPG on the highway. The highway number is respectable, and the city figure reflects urban stop-and-go driving. The twin-turbocharged engine needs fuel to deliver its power, especially when using the Sport or Sport Plus driving modes, which encourage higher engine speeds and more aggressive gear changes. The eight-speed automatic transmission (AM-S8) is generally smooth and efficient, but it won’t perform miracles when pushed hard.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Porsche Panamera 4S Sport Turismo at $3,050. This is based on driving 15,000 miles per year and using national average fuel prices. Fuel prices fluctuate, so your actual cost may vary. The calculation assumes a city to highway driving ratio, and if you primarily drive in urban areas with heavy traffic, expect to exceed the $3,050 estimate. If your driving is predominantly on open highways, you might save money. This figure provides a baseline for anticipating ownership costs for the Panamera 4S ST.

Real-world expectations

Achieving the EPA’s 19 MPG combined rating requires effort. Aggressive driving, frequent use of Sport modes, and short trips will negatively impact fuel economy. With a gentler driving style, mindful acceleration, and a focus on highway cruising, it’s possible to get close to the EPA figures. Premium fuel is required, adding to the overall cost.

How it compares

Compared to other high-performance wagons and sedans, the Panamera 4S Sport Turismo’s fuel economy is in the middle. The Audi RS6 Avant, with its 4.0L twin-turbo V8, achieves an EPA-estimated 15 MPG combined. The Mercedes-AMG E63 S Wagon, powered by a similar V8, posts 16 MPG combined. The BMW M5 Competition sedan, with its high-output V8, manages around 17 MPG combined. The Porsche offers better fuel efficiency than these V8 contenders, largely due to its smaller six-cylinder engine. Those cross-shopping might consider a Panamera 4 E-Hybrid Sport Turismo, which offers comparable performance with improved fuel economy thanks to its plug-in hybrid powertrain. You can also examine PANAMERA MPG across all years for more hybrid options.

Tips to maximize efficiency

Use the Panamera’s driving modes. Selecting “Normal” or “Eco” mode softens throttle response and optimizes the transmission for fuel efficiency. These modes reduce fuel consumption, especially during everyday driving.

Pay attention to tire pressure. Underinflated tires increase rolling resistance, and the engine works harder. Check your tire pressure regularly and maintain the recommended levels on the door jamb sticker. This improves fuel economy and extends tire life.

Minimize idling. Letting your car idle wastes fuel and contributes to emissions. If you anticipate being stationary for more than a minute, turn the engine off. Modern engines restart quickly and efficiently.

Practice smooth acceleration and braking. Avoid sudden bursts of acceleration or hard braking. Instead, accelerate gradually and maintain a consistent speed. Anticipate traffic conditions and brake smoothly to conserve momentum and reduce fuel consumption. Explore all Porsche fuel economy data for insights into other models’ efficiency.
