The 2021 Porsche Panamera 4 gets 20 MPG combined, and few buyers are cross-shopping it with a Prius. The Panamera 4 is for drivers who demand performance and luxury, accepting higher fuel costs for a car that corners well and devours highway miles. This isn’t about pinching pennies; it’s about experiencing sports car DNA and executive sedan practicality in either a hybrid or gasoline-only model.

City and highway performance

The Panamera 4’s 18 MPG city and 24 MPG highway ratings reflect its dual nature. In cities, the 2.9L turbocharged V6 works harder, using more fuel. The stop-start system helps, but can’t overcome the demands of city driving. On the open road, the automatic transmission and efficient engine allow for relaxed cruising, delivering better mileage. The Panamera encourages you to drive it hard, which lowers your MPG.

The performance-oriented all-wheel-drive system also contributes to overall fuel consumption. This car isn’t designed for steady, economical driving. It is designed for spirited driving, so you will see the fuel gauge plummet if you drive aggressively.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Porsche Panamera 4 at $2,900. This calculation assumes 15,000 miles of driving per year, using the national average fuel price. Individual costs will vary depending on local fuel prices and driving habits. Consider this figure a benchmark, and plan accordingly for your own style of driving. If you mostly drive in the city you can expect to exceed this number, whereas dedicated highway driving will likely result in a lower expense.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy will vary considerably. Driving style, traffic, and even tire pressure can impact mileage. Aggressive acceleration and frequent braking will reduce fuel efficiency, while smooth, consistent driving on the highway will yield better results. Expect to see numbers within a few MPG of the EPA ratings, but don’t be surprised by significant deviations. Remember to also maintain the car with proper tire inflation and general maintenance.

How it compares

Compared to other high-performance luxury sedans, the Panamera 4’s fuel economy is within range, albeit toward the lower end. The BMW M5, for instance, delivers a combined 17 MPG, emphasizing its outright performance focus. The Mercedes-AMG E63 S achieves a similar 18 MPG combined. The Audi RS7 sits closer at 19 MPG combined. While the Porsche is only slightly better on paper, that one or two MPG might be the deciding factor for some consumers. Those seeking better fuel efficiency in a similar package might consider the Panamera 4 E-Hybrid, significantly increasing MPG, but adding complexity.

Tips to maximize efficiency

Use “Normal” driving mode when commuting or cruising. The Panamera 4 offers various driving modes, and while “Sport” and “Sport Plus” enhance performance, they reduce fuel economy. Selecting “Normal” mode optimizes engine and transmission settings for efficiency during everyday driving.

The adaptive cruise control will also help conserve fuel. Anticipate traffic and maintain a steady speed whenever possible. Avoiding unnecessary acceleration and braking and stop-and-go traffic will substantially help you get closer to the EPA’s estimations. Smooth driving minimizes fuel consumption, and consistent speed keeps the engine working at its most efficient range.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Check your tire pressure regularly and inflate them to the recommended levels, which you can find on the tire placard in the driver’s doorjamb. Invest in a good tire pressure gauge and consider this maintenance critical.

Lighten the load. Excess weight in your vehicle reduces fuel efficiency. Remove unnecessary items from your trunk and passenger compartment. The Panamera itself isn’t the lightest car in its class, so eliminating extra weight can make a noticeable difference in MPG over time.
