20 MPG combined is what you get with a 2019 Porsche Panamera Turbo S e-Hybrid Sport Turismo. This isn’t a car for hypermilers. It’s for those who demand high performance and wagon practicality, and who also value the image of using less gas, even if fuel costs tell a different story. It’s for those who want to embarrass sports cars on a winding road, then load up the dogs for a weekend trip. Fuel economy is a secondary concern, but not irrelevant.

City and highway performance

The EPA’s estimates show a slight difference between city and highway driving for the Panamera Turbo S e-Hybrid ST. It gets 19 MPG in the city, increasing slightly to 22 MPG on the highway. The small difference suggests the hybrid system works hard in stop-and-go traffic, capturing energy and assisting the gasoline engine. On the open road, the 4.0L twin-turbo V8 takes over, with the electric motor playing a smaller supporting role at cruising speeds. These figures reflect the vehicle’s weight, substantial horsepower, and the inherent inefficiencies of any high-performance powertrain, even one with electric motors.

Annual fuel cost

The EPA calculates an annual fuel cost of $2,900 for the 2019 Panamera Turbo S e-Hybrid Sport Turismo. This figure is based on driving 15,000 miles per year, using a national average fuel price. Keep in mind that premium fuel is required for optimal performance, and changes in gasoline prices can significantly impact this annual expense. It’s a large sum, roughly equivalent to a month’s rent in some major cities, and a clear indicator that this vehicle isn’t designed for budget-conscious drivers.

Real-world expectations

Even with a plug-in hybrid system, achieving the EPA estimates requires effort. Consistently using the electric range, driving gently, and regularly charging the battery will be essential. Hard acceleration, frequent use of Sport or Sport Plus modes, and extended highway driving at high speeds will likely result in significantly lower fuel economy. The Panamera Turbo S e-Hybrid ST is a performance machine first, and its fuel consumption will reflect its driving style.

How it compares

Compared to other high-performance luxury wagons, the Panamera Turbo S e-Hybrid ST’s fuel economy varies. The Mercedes-AMG E63 S Wagon, with its V8, gets around 16 MPG combined. The Audi RS6 Avant, while not a plug-in hybrid, achieves a similar 18 MPG combined. If all Porsche fuel economy data is of interest, examine the brand’s complete range. The plug-in hybrid aspect of the Panamera offers a potential advantage in city driving, but it comes with the added complexity and weight of the hybrid system. Consider researching PANAMERA MPG across all years to understand the impact of the e-Hybrid system.

Tips to maximize efficiency

Use the electric range whenever possible. Short trips around town can be accomplished almost entirely on electric power, reducing fuel consumption. Make it a habit to plug in whenever you’re parked at home or at a charging station.

Use the Panamera’s regenerative braking system intelligently. Anticipate traffic flow and lift off the throttle early, allowing the electric motors to recapture kinetic energy and recharge the battery. This is effective in stop-and-go traffic.

Select the right driving mode for the situation. The Panamera offers modes, including hybrid auto, E-Hold, and E-Charge. Experiment with each and understand how they impact fuel efficiency. Avoid Sport and Sport Plus modes unless you’re trying to get maximum performance.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, leading to reduced fuel economy. Check your tire pressure regularly and inflate to the recommended levels.

Reduce weight and aerodynamic drag. Remove unnecessary items from the car and don’t use roof racks or cargo carriers when they’re not needed. These additions increase wind resistance and fuel consumption.
