19 MPG combined isn’t going to win any awards for fuel efficiency, but for the 2021 Porsche Panamera Turbo S e-Hybrid Executive, it’s almost beside the point. This is a fast, exquisitely crafted, four-door car designed for effortless cross-continental journeys. Fuel economy is a consideration, sure, but it’s far down the list of priorities for those who can afford the steep price.

City and highway performance

The EPA rates the Panamera Turbo S e-Hybrid Executive at 18 MPG in the city and 22 MPG on the highway. That city figure reflects the reality of urban driving, where the car’s weight and powerful V8 engine work against efficiency. The highway number is more achievable, thanks to the car’s smooth-shifting eight-speed automatic transmission and the ability to lean on the electric motor for assistance at cruising speeds. This is not a Prius; it’s a Porsche with a hybrid system designed primarily for performance enhancement, not maximizing every last drop of fuel. The electric motor adds instant torque, filling in any gaps in the V8’s power delivery and contributing to the car’s phenomenal acceleration.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,050 for the 2021 Porsche Panamera Turbo S e-Hybrid Executive. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and assumes the use of premium gasoline, which is mandatory for this high-performance engine. The cost can fluctuate depending on local fuel prices and individual driving habits. Someone who primarily drives short distances in the city will likely exceed that figure, while someone who does mostly highway cruising may see a somewhat lower number.

Real-world expectations

Those considering this Panamera likely have multiple vehicles in their garage, and fuel costs are a secondary consideration. Performance, comfort, and exclusivity are the priorities. While 19 MPG combined is the official figure to use for comparison purposes, real-world MPG will vary. Aggressive driving will send that number plummeting, while a more measured approach, using the electric drive modes where appropriate, can improve it somewhat. Don’t expect miracles, but do expect thrilling performance every time you put your foot down.

How it compares

Compared to its competitors, the Panamera Turbo S e-Hybrid Executive lands in a predictable spot. The Mercedes-AMG S63 e Performance, another high-performance plug-in hybrid sedan, achieves a similar combined figure. A non-hybrid competitor like the BMW M5 delivers around 17 MPG combined. The Audi RS7, another performance-oriented four-door coupe, also hovers in the same low-to-mid teens. The comparison is not really about which car saves you the most money at the pump; it’s about the level of performance and luxury you’re willing to pay for, and if you want all Porsche fuel economy data, you can find it here. Also, don’t forget to check the PANAMERA MPG across all years.

Tips to maximize efficiency

Use the car’s electric driving modes whenever possible, especially for short trips or slow-speed city driving. This will minimize reliance on the gasoline engine and can significantly improve fuel economy in those situations. Anticipate traffic flow and avoid hard acceleration and braking. Smooth, consistent driving is key to maximizing efficiency in any vehicle but particularly important in a high-performance hybrid.

Take advantage of regenerative braking by lifting off the accelerator early when approaching stops. This helps recapture energy and recharge the battery, reducing the need for the gasoline engine to provide power. Regular tire pressure checks and maintenance are crucial. Underinflated tires increase rolling resistance, which reduces fuel economy. Ensure your Panamera’s tires are properly inflated to the recommended pressure.

Consider the overall weight of the vehicle. While you can’t change the car’s inherent mass, avoid carrying unnecessary cargo. Every extra pound contributes to increased fuel consumption. Understand the driving modes and their impact on fuel consumption. The Panamera Turbo S e-Hybrid Executive offers various driving modes, each with its own fuel efficiency profile. Experiment with these modes to find the best balance between performance and efficiency for your driving style.

Finally, embrace the charging aspect of the e-Hybrid. Plugging in whenever you can, at home or at public charging stations, will reduce your gasoline consumption. A fully charged battery will allow more driving on electric power alone, maximizing your fuel savings and reducing the amount of gas you use.
