23 MPG combined might surprise someone in a Prius, but in the 2019 Porsche Panamera 4 e-Hybrid Sport Turismo, it’s almost a bonus. This vehicle isn’t bought for hypermiling; it’s a statement for those who want practicality, performance, and less gas, all in a stunning Porsche package. The hybrid system delivers exhilarating bursts of acceleration and silent electric driving, with fuel economy being a secondary benefit for owners used to paying a premium.

City and highway performance

The EPA estimates the Panamera 4 e-Hybrid ST at 21 MPG in the city and 24 MPG on the highway. While these numbers aren’t super efficient, this car has a considerable curb weight and a potent 2.9L twin-turbo V6 engine paired with an electric motor. The stop-and-go nature of city driving lets the electric motor contribute more. Highway driving relies more on the gasoline engine. The hybrid management system smoothly blends the power sources for optimal performance and efficiency in either environment.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,500 for the 2019 Porsche Panamera 4 e-Hybrid ST. This is based on driving 15,000 miles per year, with a mix of city and highway driving, using national average fuel prices at the time of calculation. Remember that this is just an estimate. Your actual fuel costs may vary depending on your driving habits, fuel prices, and electric-only driving.

Real-world expectations

While the EPA numbers are a benchmark, real-world fuel economy can vary. Owners report figures from slightly below the EPA estimates to significantly higher, especially with charging and strategic driving mode usage. Pre-conditioning the cabin while plugged in, along with electric-only mode for short trips, can improve overall fuel efficiency. However, heavy gasoline engine use, especially during spirited driving, will lower the MPG. Some owners see as high as 30 or more MPG in mixed driving thanks to regenerative braking and available electric power. High-octane fuel is recommended which impacts fuel costs.

How it compares

Compared to the non-hybrid Panamera models, the 4 e-Hybrid ST offers a clear fuel economy advantage. For example, the standard Panamera 4 Sport Turismo with the same 2.9L V6 gets around 21 MPG combined. A direct competitor is the BMW 530e xDrive iPerformance which gets around 27 MPG combined. However, the BMW gives up some driving enjoyment for efficiency. Another comparison is the Mercedes-AMG E53, which gets around 21 MPG combined and is more powerful. The Panamera’s performance and electric power appeals to buyers who want guilt-free enjoyment. If you’re exploring the Porsche brand, be sure to review all Porsche fuel economy data to contextualize the Panamera’s place in the lineup.

Tips to maximize efficiency

Use the E-Hold mode to maintain the battery’s current charge level. That will let you save electric power for specific situations, like city centers, with zero emissions. Plan your route and anticipate traffic flow maximizing E-Hold’s benefits, ensuring electric power is available when needed.

Take advantage of the regenerative braking system: lift off the accelerator instead of braking hard. This recaptures energy and replenishes the battery. This is effective in stop-and-go traffic, increasing your electric driving range and reducing wear on the brake pads.

Pre-condition the cabin while the car is plugged in. This warms or cools the interior using grid power instead of draining the battery or running the engine. Pre-conditioning improves comfort and maximizes electric range, especially in extreme temperatures.

Drive in “E-Power” mode whenever possible for shorter trips. This ensures the car prioritizes electric power, only engaging the gasoline engine when necessary for acceleration or high speeds. This is great for errands or commuting in urban environments where powertrain demands are lower.
