A combined EPA rating of 22 MPG isn’t exactly high, but for the 2021 Porsche Panamera 4 e-Hybrid Executive 2.9L 6-cyl, it’s a reasonable trade-off. This isn’t a typical fuel-sipper. It’s a stretched, luxurious, and surprisingly quick sedan designed for executives who want performance, comfort, and lower fuel costs.

City and highway performance

The EPA estimates 21 MPG in the city and 24 MPG on the highway. This reflects the Panamera 4 e-Hybrid Executive’s ability to drive on electric power alone for short distances, especially in cities. The 2.9-liter twin-turbo V6 engine, electric motor, and smooth 8-speed automatic transmission (AM-S8) deliver strong acceleration when you need it. Highway MPG is lower than other plug-in hybrids because this car is often driven at high speeds, and people often use the combined output of the gasoline and electric motors. The goal isn’t hypermiling, but easy performance.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Porsche Panamera 4 e-Hybrid Executive at $2,650. This is based on driving 15,000 miles per year, with a set percentage of city versus highway driving, using national average fuel prices. Your actual fuel expenses will change based on your driving, local fuel costs, and how often you drive in electric mode. This is just a baseline.

Real-world expectations

You won’t consistently get the EPA’s combined 22 MPG unless you actively manage the hybrid system, plug in often, and drive in electric mode more. Owners who mainly drive short distances and charge the battery can get much better MPG. But those who mostly use the gasoline engine, drive hard, or take long highway trips will likely see lower numbers. This car rewards careful drivers with better fuel economy.

How it compares

Compared to other plug-in hybrid luxury sedans, the Panamera 4 e-Hybrid Executive’s fuel economy is competitive. The BMW 745e, for example, gets similar combined MPG. Buyers aren’t only thinking about efficiency, though. Someone focused on fuel consumption would likely look at a base-model Panamera or a different vehicle. The Mercedes-Benz S580e (when available) has similar or slightly better MPG but a very different driving experience. Check PANAMERA MPG across all years for other options.

Tips to maximize efficiency

Use electric-only mode as much as possible. This is best for short commutes and errands. Charging often is important to get the most from the hybrid system. Make charging part of your day, at home, work, or public charging stations.

Use the Panamera’s regenerative braking system. This captures energy when you slow down and recharges the battery. Watch traffic and let off the gas early to get the most regenerative effect. Avoid full braking when you can, because it reduces regenerative charging.

Choose the right driving mode. The Panamera has driving modes that focus on either performance or efficiency. Choose “Hybrid Auto” or “E-Power” to get better fuel economy for everyday driving. Don’t use “Sport” or “Sport Plus” modes unless you really need the extra power, because they use more fuel.

Keep tires properly inflated. Underinflated tires increase rolling resistance, which hurts fuel economy. Regularly check your tires and inflate them to the pressure on the door jamb. This will improve efficiency, tire life, and handling.

Reduce aerodynamic drag. Remove roof racks or carriers that increase wind resistance. At high speeds, aerodynamic drag uses a lot of fuel. Keeping the car’s profile clean will help improve efficiency, especially on the highway.
