20 MPG combined isn’t the primary selling point of the 2020 Porsche Panamera Turbo S e-Hybrid. This is a car for those who demand ferocious acceleration, stunning luxury, and the ability to occasionally shock unsuspecting Prius drivers off the line, all in a surprisingly practical package. Fuel economy is simply a cost of doing business, a factor acknowledged by those capable of affording its substantial price tag.

City and highway performance

The EPA figures for the Panamera Turbo S e-Hybrid are 19 MPG in the city and 22 MPG on the highway. The relatively small difference between these numbers shows the nature of the car. This isn’t a purely gas-guzzling monster when left to its own devices. The hybrid drivetrain makes an effort to contribute, even if the result is still far from thrifty. The electric motor provides a boost during city driving, helping to offset the demands of stop-and-go traffic. The twin-turbo V8 can stretch its legs out on the open road, but its significant power output still means it’s working hard to maintain highway speeds.

Annual fuel cost

Based on the EPA’s estimates, the annual fuel cost for the 2020 Porsche Panamera Turbo S e-Hybrid is $2,900. This figure assumes 15,000 miles of driving per year, with a mix of city and highway conditions, using national average fuel prices. It’s a helpful benchmark, but remember that your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and local gas prices. Aggressive driving and frequent use of the car’s power will lead to higher expenditures.

Real-world expectations

Don’t expect to consistently match the EPA’s figures in the real world, especially if you’re prone to exploiting the car’s performance. While the hybrid system offers some electric-only driving, its range is limited. A heavy right foot will quickly drain the battery and force the V8 to shoulder the majority of the load. Drivers who prioritize efficiency and use the electric drive mode as much as possible can likely get close to the EPA estimates. The temptation to unleash the car’s power is ever-present, and that’s where fuel economy will suffer.

How it compares

Compared to other high-performance luxury sedans, the Panamera Turbo S e-Hybrid’s fuel economy is a mixed bag. The Mercedes-AMG S63 Sedan manages a similar 19 MPG combined, making the Porsche’s hybrid powertrain look somewhat less impactful. For drivers considering similar vehicles, all Porsche fuel economy data should factor into the decision. More standard, non-hybrid Panamera models, such as the Panamera 4, achieve a more respectable 24 MPG combined. The BMW M5 Competition, another rival, nets around 17 MPG combined, making the Panamera seem relatively efficient. Buyers cross-shopping the various options must carefully evaluate the balance between performance, features, and fuel consumption to find the best fit. See PANAMERA MPG across all years for details.

Tips to maximize efficiency

Use the electric drive mode whenever possible. For short trips around town, prioritizing electric power can significantly reduce fuel consumption. Get to know the car’s different driving modes, as using the “E-Hold” mode will prevent battery discharge, and “E-Charge” will allow you to recharge on the go, but at a fuel economy penalty.

Gentle acceleration and consistent speeds are key. Avoid aggressive starts and hard braking, as these actions quickly deplete the battery and force the V8 engine to work harder. Maintaining a steady pace on the highway will also contribute to better fuel efficiency.

Regular maintenance is essential for optimal performance. Ensure the car is properly serviced, including regular tire pressure checks and timely oil changes. A well-maintained engine will run more efficiently and improve fuel economy.

Minimize unnecessary weight. Carrying excessive cargo increases the vehicle’s load and reduces fuel efficiency. Remove any unnecessary items from the trunk and passenger compartment to lighten the load and improve gas mileage.
