22 MPG combined might surprise some when talking about fuel-sipping hybrids, but for high-performance luxury sedans like the 2018 Porsche Panamera 4 e-Hybrid, it’s a good mix of power and decent fuel economy. This isn’t a Prius competitor; it’s a Panamera, a car built for exciting performance and luxurious comfort first, with fuel economy as a secondary, but still important, factor.

City and highway performance

The EPA estimates for the 2018 Panamera 4 e-Hybrid are 20 MPG in the city and 25 MPG on the highway. The slightly lower city MPG is normal for hybrids, where stop-and-go traffic isn’t always managed well, even with regenerative braking. On the open road, however, the hybrid system uses its electric motor to help the 2.9L twin-turbo V6, allowing for more relaxed cruising and better fuel conservation. The smooth-shifting 8-speed automatic transmission (AM-S8) optimizes both performance and efficiency in various driving conditions. This powertrain delivers transitions between electric and gasoline power, helping with both fuel efficiency and the car’s impressive performance.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Porsche Panamera 4 e-Hybrid at $2,650. This is based on driving 15,000 miles per year, with a mix of city and highway driving, and using national average fuel prices at the time of calculation. Individual driving habits and local fuel costs will change the actual fuel costs. Aggressive driving, frequent use of Sport modes, and higher fuel prices will all raise the annual fuel bill. The hybrid system can reduce fuel expenses, but it depends on how often the vehicle is charged and driven in electric mode.

Real-world expectations

While the EPA numbers provide a standardized benchmark, real-world fuel economy for the 2018 Panamera 4 e-Hybrid often changes. Drivers who frequently the electric-only mode, especially for shorter commutes, can exceed the EPA’s combined MPG estimate. But, those who want performance and often use the engine’s full power will likely see numbers closer to the city rating, or even lower. The Panamera e-Hybrid adapts to your driving style. It delivers the performance that Porsche owners expect and has enough electric range to cover local drives.

How it compares

The 2018 Panamera 4 e-Hybrid is unique compared to other high-performance large sedans. A non-hybrid V6 Panamera gets around 21 MPG combined. The BMW 740i, another popular choice, delivers around 25 MPG combined with its inline-6 engine. The Mercedes-Benz S560 sees around 20 MPG combined. The Audi A8 averages around 22 MPG. A Tesla Model S is much more efficient as an all electric vehicle. The Panamera’s e-Hybrid variant is a good middle ground: better fuel economy than its gasoline-powered siblings and some competitors, with the performance and luxury expected from a Porsche. Those shopping for a PANAMERA MPG across all years will find that the e-Hybrid often provides the most frugal ownership experience.

Tips to maximize efficiency

Use electric-only mode for short trips and city driving. The Panamera 4 e-Hybrid has limited all-electric range, but using it when possible minimizes gasoline consumption and maximizes overall fuel efficiency. Regular charging is key to using the hybrid system best.

Use regenerative braking by gently lifting off the accelerator and letting the car slow down naturally. Hard braking reduces the energy recovered and stored in the battery, lowering the efficiency of the hybrid system.

Avoid hard acceleration and high speeds, especially on the highway. The 2.9L twin-turbo V6 is fun to push, but fuel consumption rises when the engine is pushed hard. A smoother driving style will yield better MPG.

Proper tire inflation improves fuel economy. Check and maintain recommended tire pressure regularly, as underinflated tires raise rolling resistance and reduce efficiency. Check all Porsche fuel economy data to see general practices for maintaining efficiency.

Reduce unnecessary weight in the vehicle. Removing heavy items from the trunk or rear seats reduces the load on the engine and electric motor, slightly improving fuel economy, especially during city driving.
