20 MPG combined is likely not the primary concern for buyers of the 2023 Porsche Panamera 4S. It’s a performance sedan, a sports car with four doors, where fuel efficiency is a recognized trade-off for speed, handling, and its respected brand. It’s a Porsche, not a Prius.

City and highway performance

The Panamera 4S, with its smooth 2.9L twin-turbo V6, achieves 18 MPG in the city and 24 MPG on the highway. The city MPG reflects typical urban driving with frequent stops. The highway MPG indicates better fuel economy for longer trips where the engine maintains a consistent speed. The standard eight-speed automatic transmission (AM-S8) has closely spaced gears for quick acceleration and taller overdrive gears for efficient cruising. This allows the car to achieve respectable highway mileage while providing quick bursts of power.

Annual fuel cost

The EPA estimates the 2023 Panamera 4S will have an annual fuel cost of $2,900. This is based on 15,000 miles driven per year, with 55% of those miles in the city and 45% on the highway. The calculation uses the current national average gas price. Actual costs will vary based on individual driving habits, local fuel prices, and the gasoline grade used. Still, $2,900 is a benchmark for comparisons with other vehicles in its class. For those accustomed to luxury, this cost is likely factored into overall ownership.

Real-World Expectations

EPA estimates are a standardized baseline, but real-world fuel economy often differs. Aggressive driving, frequent Sport or Sport Plus mode use, and long idling periods can lower fuel efficiency. Mindful driving, correct tire pressure, and minimal accessory use, like air conditioning, could bring mileage closer to EPA estimates. Panamera 4S drivers aren’t known for hypermiling; they usually focus on performance. Even performance drivers can benefit from some fuel-saving techniques.

How It Compares

The 2023 Porsche Panamera 4S compares well to its competitors, though isn’t the most fuel efficient. The BMW M5, with its more powerful V8 engine, achieves around 17 MPG combined. The Mercedes-AMG E63 S sedan, another V8 competitor, is similar. The Audi S7, which also has a V6, achieves around 22 MPG combined. These MPG numbers highlight the Panamera 4S’s balance of performance and efficiency. The Panamera 4 E-Hybrid, a plug-in hybrid, is an alternative if fuel economy is a priority.

Tips to Maximize Efficiency

Make the most of the Panamera’s driving modes. The ‘Normal’ mode adjusts throttle response, shift points, and other engine settings to prioritize fuel efficiency. Only use Sport or Sport Plus modes when you want maximum performance. Responsiveness changes noticeably, and so does fuel consumption.

Check tire pressures. Correctly inflated tires lower rolling resistance, which improves fuel economy and handling. Check pressures regularly, especially when the temperature changes, and follow Porsche’s recommended specifications for the vehicle.

Anticipate traffic. Reduce sudden acceleration and braking. Maintain a consistent speed whenever possible. This smooth driving minimizes wasted energy and improves fuel efficiency. Give yourself extra time to avoid rushing for more relaxed and economical driving.

Minimize idling. Modern engines are designed to be efficient while running, and idling wastes fuel. Turn off the engine if you’re stopped for longer than a minute. The start/stop system will do this automatically in specific situations. Read all Porsche fuel economy data to prepare for buying.
