17 MPG combined is what you’ll get if you want Porsche performance in a practical and beautiful wagon. The 2023 Panamera Turbo S Sport Turismo isn’t about saving fuel; it’s about incredible acceleration, precise handling, and the appeal of a high-performance wagon. If you’re trying to get the best gas mileage, this isn’t the car for you. This is for drivers who want supercar performance and the ability to haul cargo and passengers in style.

City and highway performance

The EPA estimates the Panamera Turbo S ST gets 15 MPG in the city and 21 MPG on the highway. These numbers come from the powerful 4.0L twin-turbo V8 engine, which produces 620 horsepower. Stop-and-go city driving reduces fuel economy, since the engine uses more fuel to accelerate. Highway driving is better, but it’s affected by the car’s weight, all-wheel drive, and how easily it speeds up. Consistent speed will mirror EPA estimates, but that’s hard to do on the open road.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Porsche Panamera Turbo S Sport Turismo at $3,400. This is based on driving 15,000 miles per year, with 55% in the city and 45% on the highway. It assumes a national average fuel price, which varies. This annual fuel cost is a guide, and your expenses may be higher or lower depending on driving and location.

Real-world expectations

The EPA provides a standard rating, but real-world fuel economy changes. Driving hard, launch control, and idling decrease your MPG. Adaptive cruise control and conservative highway driving can help you get close to the EPA’s 21 MPG rating. The Panamera’s drivetrain and engine management systems optimize fuel, but the driver has the ultimate control.

How it compares

The Panamera Turbo S ST’s fuel economy is comparable to similar cars. The Mercedes-AMG E63 S Wagon, a high-performance wagon, gets around 16 MPG combined. The BMW M5 CS sedan gets around 17 MPG combined. The Audi RS7 is near 18 MPG. These cars serve the same customers who want the same things. Small MPG differences are not important for those buying in this category. They care more about performance and luxury, and those who want to save on gas would buy hybrid models.

Tips to maximize efficiency

Despite its performance, you can improve the Panamera Turbo S ST’s fuel economy. Avoid fast acceleration and high-speed driving. The twin-turbo V8 is responsive, but fuel use increases with heavy throttle. Anticipate traffic and keep a steady speed to avoid braking and accelerating, which use more fuel.

Use the Panamera’s “Normal” driving mode when you can. This mode optimizes the engine and transmission for efficiency, reducing fuel use compared to “Sport” modes. It’s tempting to drive in sport mode, but understand that the engine holds lower gears and works harder to achieve full power.

Keep your tires inflated. Underinflated tires increase rolling resistance, reducing fuel economy. Check your tire pressure and inflate them to the recommended levels on the doorjamb sticker. This improves your MPG.

Don’t idle. Letting the engine idle uses fuel. If you’re waiting, turn off the engine. Modern engines start easily, so idling isn’t useful.

Use premium fuel as Porsche recommends. This ensures optimal engine performance and efficiency. Lower octane fuel may trigger knock sensors, which could retard timing and slightly reduce performance and fuel economy. You can explore all Porsche fuel economy data on our site.
