22 MPG combined won’t win any fuel efficiency contests, but it’s acceptable for the 2021 Porsche Panamera 4S e-Hybrid Executive. This isn’t a Prius, it’s a long-wheelbase luxury sedan that delivers near-supercar performance, while also offering some all-electric driving. The buyers of this vehicle, typically successful professionals who value both driving experience and lower fuel costs, understand this trade-off.

City and highway performance

The EPA estimates 21 MPG in the city and 23 MPG on the highway. These numbers show how the vehicle can use its electric motor in stop-and-go traffic. Highway driving sees the hybrid system maintaining efficiency at higher speeds. The Panamera 4S e-Hybrid Executive uses a turbocharged engine with an electric motor, resulting in smooth power delivery and decent fuel consumption. Aggressive driving, which this car seems to encourage, will quickly lower fuel economy regardless of where you drive.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Porsche Panamera 4S e-Hybrid Executive will be $2,650. This is based on driving 15,000 miles per year and using national average fuel prices. Real-world fuel costs will change depending on individual driving habits, local fuel prices, and the time spent driving in all-electric mode. Those who consistently charge the battery and drive electric will see lower fuel costs than those who only use the hybrid system for performance.

Real-world expectations

The Panamera 4S e-Hybrid Executive’s official MPG numbers are a guide. Real-world results often vary because of many things. Driving style is important, and so is the outside temperature. Cold weather can reduce both fuel efficiency and electric range. The amount of time spent driving in electric-only mode makes a big difference; charging often and using electric power for shorter trips will really improve your MPG. Expect numbers close to the EPA estimates during normal driving, but spirited driving or forgetting to charge the battery will lower those numbers.

How it compares

Compared to other luxury hybrid sedans, the Panamera 4S e-Hybrid Executive is special. The BMW 745e xDrive, another plug-in hybrid luxury sedan, gets a combined 22 MPG. The Porsche prioritizes performance unlike the BMW, while the Mercedes-Benz S580e Plug-in Hybrid gets 21 MPG combined. For those cross-shopping with conventional gasoline engines, the non-hybrid Panamera 4S achieves around 21 MPG combined, showing the fuel-saving potential of the e-Hybrid system, though still, not all Porsche get these MPG levels.

Tips to maximize efficiency

Take full advantage of the car’s electric capabilities. The Panamera 4S e-Hybrid Executive has a usable all-electric range. By regularly charging and using electric power for short trips, you’ll reduce your reliance on gasoline and improve your overall fuel economy.

Use the car’s driving modes intelligently. The Panamera offers modes to optimize performance or efficiency. “E-Power” mode prioritizes electric driving, while “Hybrid Auto” blends gasoline and electric power for efficiency. Use the right mode for each situation to save fuel.

Drive smoothly. Hard acceleration and braking use more fuel. By keeping a steady speed and watching traffic, you can minimize wasted energy and improve gas mileage. The Panamera’s responsive engine can tempt you to drive fast, but try to resist it.

Check tire pressure. Underinflated tires increase rolling resistance, which hurts fuel economy. Check your tire pressure often and inflate them to the right level as shown on the doorjamb sticker. Proper tire inflation improves fuel efficiency and enhances handling and tire life.

Remove extra weight. Carrying extra weight in your car reduces fuel economy. Remove unnecessary items from your trunk or backseat to lighten the load and improve your gas mileage. This might seem small, but it helps when trying to get more miles from each gallon.
