20 MPG combined isn’t going to win any efficiency awards, but that’s probably not the main concern for someone considering a 2020 Porsche Panamera Turbo S e-Hybrid Executive. This isn’t a car purchased for saving money on gas; it’s bought for its outstanding performance, lavish interior, and the prestige of owning one of the most technologically advanced and powerful grand tourers available. Fuel efficiency, in this case, is a necessary compromise, not a priority.

City and highway performance

The EPA estimates of 19 MPG in the city and 22 MPG on the highway show the Panamera Turbo S e-Hybrid Executive’s mixed nature. In heavy, stop-and-go traffic, the hybrid system can lead to a fairly respectable MPG rating because the gasoline engine sometimes shuts off due to the electric motor. However, the vehicle’s weight, coupled with the frequent bursts of acceleration it encourages, keeps it from truly excelling. Out on the open road, the powerful 4.0L V8 can perform well, providing effortless cruising and respectable highway numbers. However, even then, the temptation to use its full power reduces fuel economy.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2020 Porsche Panamera Turbo S e-Hybrid Executive is $2,900. 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, but probably an acceptable expense for the target customer. The buyer considering this vehicle is less sensitive to gas prices and more focused on the complete ownership experience, which includes thrilling performance and high-end luxury.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy for the Panamera Turbo S e-Hybrid Executive can change a lot depending on driving style and how it’s used. Those who often use the car’s full power, drive aggressively, or spend a lot of time in Sport or Sport Plus mode will likely see MPG figures below the EPA estimates. On the other hand, drivers who drive more calmly and try to maximize the electric driving range might achieve slightly better results, at least for shorter commutes. The tempting sound of the V8 and the car’s fast acceleration encourage a heavy right foot. The all-electric range is relatively short, around 19 miles, which means that longer trips will mostly use the gasoline engine.

How it compares

Compared to other high-performance luxury sedans, the Panamera Turbo S e-Hybrid Executive’s fuel economy is typical. The Mercedes-AMG S63, with its similarly strong V8, gets around 17 MPG combined. A BMW M760i, with its V12 engine, does even worse, typically getting around 16 MPG combined. Even the non-hybrid Porsche Panamera Turbo with the same engine yields similar numbers, showing the small efficiency gains of the hybrid system. For those seeking increased efficiency within the Panamera lineup, they can view PANAMERA MPG across all years to see how each trim performs. Buyers in this class prioritize performance and luxury over outright fuel savings, accepting the trade-offs of owning such a powerful and capable vehicle. For all Porsche fuel economy data, the Panamera Turbo S e-Hybrid Executive still represents a step towards less gas without sacrificing a lot of speed compared to older, gas-guzzling models.

Tips to maximize efficiency

Use E-Power mode for short trips and city driving to prioritize electric power when you can, especially during low-speed commutes. Keep in mind that the electric range is limited, so you will eventually run out of battery.

Use the hybrid-specific driving modes. Select Hybrid Auto for optimal energy management, which tries to balance electric and gasoline power based on driving conditions and navigation data. Try E-Hold mode to save the battery’s charge for later use in urban areas.

Drive with smooth and careful acceleration. Avoid aggressive throttle, as that will immediately engage the gasoline engine and reduce fuel economy. Gentle acceleration and watching traffic can significantly improve efficiency.

Make sure your tires are properly inflated. Correct tire pressure reduces rolling resistance, which improves fuel economy. Check tire pressures often and keep them at the recommended levels.

Think about your charging schedule. Plug in the Panamera whenever possible to keep the battery charged. Getting the most out of the electric range is the easiest way to reduce fuel consumption, especially if your daily driving is just short trips.
