The 2023 Porsche Panamera 4 Executive with its 2.9L six-cylinder engine gets 19 MPG combined. It’s not going to win any fuel-efficiency contests, but that number shouldn’t surprise the affluent buyers who value space, performance, and prestige. This long-wheelbase Panamera is for executives and those who often travel with rear passengers, delivering an experience different from volume-selling luxury sedans.

City and highway performance

The EPA estimates the Panamera 4 Executive gets 17 MPG in the city and 23 MPG on the highway. These figures show the compromise between the Panamera’s powerful twin-turbocharged engine and its heavy weight. Stop-and-go city driving causes lower fuel economy as the engine works harder to accelerate the heavy car. Highway driving, at consistent speeds and with less acceleration, lets the engine operate more efficiently, closer to its potential.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Porsche Panamera 4 Executive is $3,050. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary depending on how you drive, local fuel prices, and the type of fuel you use. Porsche recommends premium fuel for best performance, which usually costs more per gallon. However, given the Panamera 4 Executive’s original MSRP and the type of buyer it attracts, this annual fuel cost is likely not a major concern. Performance and experience usually matter more than fuel costs in the luxury performance segment.

Real-world expectations

EPA estimates are a useful benchmark, but real-world fuel economy can change a lot depending on driving style and conditions. Driving hard, accelerating often, and idling for long periods will all lower fuel economy. Gentle acceleration, consistent speeds, and minimal idling can help you get numbers closer to, or even a little better than, the EPA estimates. Because of the type of driver who buys this car, many owners will enjoy its performance, which brings fuel economy down to the stated numbers.

How it compares

Compared to its competitors, the Panamera 4 Executive’s fuel economy is in a specific spot. The BMW 740i with its 3.0L inline-six gets a slightly better estimated 25 MPG combined, making it more fuel-efficient, but it offers a different driving experience. The Mercedes-Benz S500, with a similar engine to the Panamera, gets around 24 MPG combined. These numbers show the trade-off between performance, luxury, and efficiency in this class. See all Porsche fuel economy data to compare with other models. Buyers considering the Panamera 4 Executive often compare these vehicles, but they often choose the Porsche for its driver-focused dynamics, even if it means fewer MPGs. This is important because of the higher cost of ownership and insurance in addition to higher fuel consumption. For PANAMERA MPG across all years please check here.

Tips to maximize efficiency

The Panamera 4 Executive has a twin-turbocharged engine, so avoid accelerating hard and braking hard. Smooth and progressive use of the gas pedal will help save fuel and keep momentum. The Porsche’s automatic transmission works best when it’s not forced to shift constantly under heavy load.

Use the Panamera’s driving modes. Select “Normal” or “Eco” mode when cruising or during easy driving. These modes change engine and transmission settings for best fuel efficiency, changing the car’s response a little without hurting performance too much. “Sport” or “Sport Plus” modes improve responsiveness, but they will also lower fuel economy greatly.

Make sure your tires have the right amount of air. Correct tire pressure lowers rolling resistance and improves fuel efficiency. Check your tire pressure often and keep it at the number on the tire placard, usually on the driver’s side doorjamb. Tires with too little air not only waste fuel but also hurt handling and tire life.

Take out extra weight from the car. Every extra pound makes the engine work harder and lowers fuel economy. Take any heavy items out of the trunk or rear seats that you don’t need. The Panamera 4 Executive is already a large vehicle, so taking out extra weight can change fuel use.
