17 MPG combined won’t impress a Prius owner, but for the 2022 Porsche Panamera GTS 4.0L 8-cylinder, it’s the expected trade-off. Nobody buys a Panamera GTS for its fuel efficiency. They buy it for the mix of performance, luxury, and practical four-door design. The V8’s sound as it accelerates to 60 mph in under four seconds matters more than concerns about gas station visits. This is a car for enthusiasts who need to transport clients or children and who understand that sometimes compromise isn’t an option.

City and highway performance

EPA estimates show the Panamera GTS’s consumption in different conditions. The 15 MPG city rating reflects urban driving, where the V8 constantly battles its own weight. Expect frequent fill-ups if you drive in stop-and-go traffic. The open road improves things slightly, with a 21 MPG highway rating. This shows the engine’s ability to cruise more efficiently. The automatic (AM-S8) transmission selects the best gear for cruising, helping to minimize fuel use.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Porsche Panamera GTS at $3,400. This is based on driving 15,000 miles per year, with a mix of city and highway driving, and using national average fuel prices. It’s a large sum, and it’s important to consider this in the overall cost. The $3,400 figure is based on average fuel prices, and market changes can affect this cost. Consider this a baseline for fueling this vehicle.

Real-world expectations

EPA estimates are standardized, but real-world fuel economy varies based on driving style, conditions, and weather. Aggressive driving will lower the MPG below EPA estimates. Driving more calmly can improve results. The Panamera GTS has driving modes that affect fuel efficiency. “Normal” mode prioritizes fuel economy by optimizing throttle response and shift points, while “Sport” and “Sport Plus” modes prioritize performance.

How it compares

The Panamera GTS’s fuel economy is similar to other high-performance luxury sedans. The Mercedes-AMG GT 63 S, also powered by a turbocharged V8, achieves a similar 15 MPG city and 21 MPG highway. The BMW M5 Competition, with its twin-turbocharged V8, manages a slightly better 15 city and 22 highway. Even all-electric options like the Porsche Taycan Turbo S have charging considerations. The Panamera GTS buyer is probably less concerned with saving every last mile and more focused on the driving experience. If fuel economy is a primary concern, potential Porsche buyers should review all Porsche fuel economy data or potentially consider a less performance-oriented Panamera model or review the PANAMERA MPG across all years.

Tips to maximize efficiency

The Panamera GTS isn’t highly fuel-efficient, but you can improve its MPG. Avoid aggressive acceleration and braking, especially in city driving. Smooth throttle and anticipating traffic can reduce fuel use.

Use the Panamera’s driving modes. “Normal” mode optimizes engine and transmission settings, making it good for commuting. Save “Sport” and “Sport Plus” modes for performance.

Keep your tires inflated. Underinflated tires increase resistance, which reduces fuel economy. Check your tire pressure and inflate them to the recommended levels, found on the driver’s side doorjamb sticker.

Reduce unnecessary weight. Extra cargo increases the engine load, requiring more fuel. Remove any non-essential items, such as golf clubs or tools.

Combine trips and plan routes. Shorter trips often lower fuel economy because the engine doesn’t reach temperature. Combining errands and avoiding traffic can improve your MPG.
