The 2020 Porsche Panamera 4 e-Hybrid Sport Turismo achieves a combined EPA-estimated 23 MPG. This may not impress those looking for the best possible fuel economy, but it offers a good balance for buyers who prioritize performance and practicality over saving every drop of fuel. It’s a true Porsche, combined with the practicality of a wagon and the efficiency of a plug-in hybrid system. Its buyers are professionals who want a vehicle that can transport clients in comfort, provide thrilling performance on a back road, and deliver good fuel economy during daily commutes.

City and highway performance

The Panamera 4 e-Hybrid ST gets 21 MPG in the city and 24 MPG on the highway, showing a relatively narrow fuel economy range. This is because of the electric motor’s consistent contribution. The city figure shows the hybrid system’s ability to recapture energy during braking and electric power at lower speeds, which reduces the fuel consumption usually seen with a high-performance engine in stop-and-go traffic. The highway number, while slightly higher, means that continuous high-speed driving will depend more on the gasoline engine, which will affect fuel efficiency. These ratings are important for buyers who divide their time between city driving and longer road trips, which is what Porsche intended.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Porsche Panamera 4 e-Hybrid ST at $2,500. This is based on driving 15,000 miles per year and using national average fuel prices. While this is a helpful guide, actual fuel costs will change depending on local fuel prices, driving habits, and how much the electric range is used. For Panamera 4 e-Hybrid ST owners who regularly plug in and use the electric motor for shorter trips, the actual annual fuel cost could be much lower, even less than many gasoline-powered luxury sedans.

Real-world expectations

While the EPA ratings are a useful starting point, real-world fuel economy often varies. Aggressive driving, frequent use of Sport or Sport Plus modes, and infrequent charging of the hybrid battery can all lower fuel consumption. A conservative driving style, regular charging, and maximizing the use of the electric-only mode can increase fuel economy above the EPA estimates, particularly in cities. The driver’s behavior is very important in determining the long-term fuel efficiency of the Panamera 4 e-Hybrid ST. Using all all Porsche fuel economy data as a reference can provide further insights.

How it compares

Compared to other high-performance wagons and luxury sedans, the Panamera 4 e-Hybrid ST is in a unique position. The Mercedes-AMG E63 S Wagon, with its powerful V8, achieves only around 19 MPG combined and has no electric assistance, prioritizing power over efficiency. The similar Audi RS6 Avant gets about 18 MPG combined. The non-hybrid Porsche Panamera 4S Sport Turismo is rated at 21 MPG combined, so the hybrid is a good choice for efficiency. Comparing PANAMERA MPG across all years can show you this.

Tips to maximize efficiency

Regular charging is important for maximizing the fuel efficiency of the Panamera 4 e-Hybrid ST. Plug in as often as possible, at home, at work, or at public charging stations, to keep the battery charged and reduce the need for the gasoline engine.

Use the car’s hybrid-specific driving modes. Select “E-Power” for electric-only driving in urban areas or “Hybrid Auto” to allow the car to intelligently manage the gasoline engine and electric motor for the best fuel efficiency on longer trips.

Avoid hard acceleration and braking. Gentle actions reduce energy waste and maximize the regenerative braking system’s ability to recharge the battery. Watch traffic conditions and plan your routes to reduce stop-and-go driving.

Check tire pressure regularly to make sure rolling resistance is as low as possible. Underinflated tires can greatly reduce fuel economy. and reducing unnecessary weight in the vehicle can also improve fuel efficiency.

Consider using the Porsche Connect app to pre-condition the cabin while the car is plugged in. This reduces the energy used by the battery or gasoline engine when you start driving, especially in very hot or cold weather.
