17 MPG combined. If that number worries you, the 2023 Porsche Panamera GTS Sport Turismo is not for you. This isn’t about grocery runs; it’s about enjoying the drive in a high-performance wagon. The GTS badge means athleticism and practicality, and fuel efficiency isn’t the priority. We’re talking about a 4.0-liter, twin-turbocharged V8 with 473 horsepower and 457 lb-ft of torque. Fuel consumption is secondary.

City and highway performance

The EPA estimates show what the Panamera GTS Sport Turismo can do. Expect 15 MPG in the city and 20 MPG on the highway. The city figure reflects stop-and-go traffic where the V8 overcomes the car’s weight. The highway number is better, showing the engine cruising at lower RPMs. But even 20 MPG has caveats: aggressive driving will quickly lower the fuel level. The eight-speed automatic transmission (AM-S8) optimizes fuel use, but physics and the driver’s foot are the ultimate factors.

Annual fuel cost

The annual fuel cost is about $3,400, according to EPA estimates. This is based on 15,000 miles per year, with mixed driving, and using average fuel prices. Your driving habits will change this number. Aggressive driving, short trips, and idling will increase it. Highway driving with conservative throttle could lower it.

Real-world expectations

Don’t expect to match the EPA numbers in the real world. The Panamera GTS Sport Turismo is made to be driven hard. The exhaust sounds great, the acceleration is addictive, and the handling is sharp for its size. The typical buyer isn’t thinking about fuel efficiency. They are buying a wagon with supercar performance. They accept the trade-off, knowing that the thrill of driving a powerful Porsche costs more at the pump. If you want Prius-like mileage, don’t buy a twin-turbo V8.

How it compares

The Panamera GTS Sport Turismo’s fuel economy reflects its performance. A Mercedes-AMG E63 S Wagon has similar power and performance, and its fuel economy is about 16 MPG combined. The Audi RS6 Avant, a competitor, gets about 18 MPG combined. A Porsche Cayenne Turbo S E-Hybrid has slightly better MPG because it’s a hybrid, but it costs more. The BMW M5 sedan gets about 17 MPG combined. Great performance comes at a price, and fuel efficiency isn’t usually a priority.

Tips to maximize efficiency

While fuel efficiency isn’t the main concern, here are steps to reduce the Panamera GTS Sport Turismo’s fuel consumption. Avoid idling. The large V8 uses a lot of fuel when stopped. Turn off the engine during long stops to save fuel.

Use the Porsche’s driving modes. “Normal” mode reduces throttle response and optimizes the transmission for efficiency. While it reduces performance, it can improve fuel economy during daily driving. Use “Sport” and “Sport Plus” modes when you want to enjoy the Porsche’s capabilities.

Keep tires properly inflated. Underinflated tires increase rolling resistance, making the engine work harder and use more fuel. Check tire pressures and inflate them to the recommended levels. This helps.

Anticipate traffic and avoid hard acceleration and braking. Smooth driving minimizes fuel consumption. By anticipating traffic changes, you can reduce sudden acceleration or braking, which stresses the engine and wastes fuel. Owners looking for PANAMERA MPG across all years can find data online.

Consider the weight you’re carrying. While the Sport Turismo is for hauling, reducing cargo weight lightens the load, improving fuel economy. Remove unnecessary items to maximize efficiency.
