20 MPG combined won’t break any records, but for the 2022 Porsche Panamera 4 Sport Turismo with its 2.9L twin-turbo V6, it’s an acceptable trade-off for a distinctive blend of performance, luxury, and practicality. Panamera 4 ST buyers likely aren’t prioritizing fuel efficiency above all else. They’re drawn to its sleek design, powerful engine, impressive handling, and the added cargo space afforded by the Sport Turismo body style. They want a unique vehicle that can handle both spirited driving and everyday errands, and the Panamera 4 ST delivers on that promise, even if it means more trips to the gas station.

City and highway performance

The EPA estimates for the Panamera 4 Sport Turismo break down to 18 MPG in the city and 23 MPG on the highway. The city figure reflects the stop-and-go conditions where the twin-turbo V6 is constantly working to accelerate its substantial weight, while the highway number suggests a more relaxed cruising efficiency. The 8-speed automatic transmission (AM-S8) plays a key role in optimizing fuel economy at higher speeds, keeping the engine at a lower RPM when possible. However, the temptation to tap into the engine’s readily available power will undoubtedly impact real-world highway MPG for most drivers.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2022 Porsche Panamera 4 ST 2.9L 6-cyl is exactly $2,900. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. Actual fuel costs will vary depending on individual driving habits, local fuel prices, and the type of fuel used. Porsche recommends premium gasoline for optimal performance, so drivers should factor in the higher cost of premium fuel and consult all Porsche fuel economy data.

Real-world expectations

While the EPA figures provide a useful baseline, it’s important to have realistic expectations for the Panamera 4 ST’s real-world fuel economy. Drivers who frequently accelerate quickly, navigate congested city streets, or drive in colder climates may see numbers closer to the city estimate, or even lower.

Conversely, those who prioritize smooth, consistent driving and spend more time on the open highway may achieve fuel economy closer to, or even slightly exceeding, the EPA highway rating. Ultimately, individual driving habits and conditions will have a significant impact on fuel consumption.

How it compares

Compared to its competitors, the 2022 Panamera 4 ST’s fuel economy sits within a normal range. The Mercedes-AMG CLS 53, for instance, achieves a combined 21 MPG. The BMW M550i xDrive, a performance sedan with similar power output, manages around 20 MPG combined, mirroring the Panamera’s figure. Even Porsche’s own Cayenne SUV, in a comparable trim, often struggles to surpass 20 MPG combined. These comparisons are relevant because Panamera buyers often cross-shop these vehicles, weighing performance, luxury, and practicality, with fuel economy as just one factor among many. It’s worth exploring PANAMERA MPG across all years, as well.

Tips to maximize efficiency

Drive smoothly and avoid excessive acceleration. The Panamera 4 ST’s twin-turbo V6 provides ample power, but resist the urge to constantly tap into it. Gradual acceleration and maintaining a steady speed will significantly improve fuel economy.

Take advantage of the Panamera’s driving modes. Selecting “Normal” or “Eco” mode can optimize engine and transmission settings for fuel efficiency. These modes often reduce throttle response and shift points to minimize fuel consumption.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. Check your tire pressure regularly and maintain the recommended levels as indicated on the doorjamb sticker.

Reduce unnecessary weight. Carrying excessive cargo adds to the vehicle’s overall weight, requiring more energy to accelerate and maintain speed. Remove any unnecessary items from the trunk or rear seats to improve fuel efficiency.

Consider your route and driving time. Avoiding peak traffic hours and planning routes with fewer stops and starts can save fuel. Idling consumes fuel, so try to minimize idling time whenever possible.
