19 MPG combined isn’t going to win any hypermiling awards, but for the 2023 Porsche Panamera Turbo S e-Hybrid, it’s almost beside the point. Let’s be honest: nobody shelling out well north of $200,000 for a 690-horsepower, twin-turbocharged V8 plug-in hybrid is prioritizing fuel efficiency above all else. They’re buying blistering acceleration, luxury appointments, and the prestige of owning a Porsche, and accepting the fuel bill as the price of admission.

City and highway performance

The EPA estimates for the Panamera Turbo S e-Hybrid break down to 18 MPG in the city and 22 MPG on the highway. These aren’t numbers that will impress anyone coming from a Prius, but consider the immense performance potential. The electric motor provides instant torque that helps to offset the weight. In electric mode, the car can achieve limited range at slower speeds, which improves city MPG considerably compared to similar cars without the electric motor.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2023 Porsche Panamera Turbo S e-Hybrid at $3,050. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. It also assumes the use of current national average fuel prices, which changes with seasonal conditions. For someone already writing checks for a car this expensive, the fuel cost is a smaller consideration.

Real-world expectations

Drivers can expect to see figures close to the EPA estimates in mixed driving conditions. Aggressive acceleration, frequent use of Sport or Sport Plus modes, and extended highway cruising at higher speeds, will push fuel consumption upwards. Using the electric motor for shorter trips around town can improve overall efficiency. Some reviewers have observed better numbers when driving conservatively, approaching 25 MPG on longer highway hauls. Of course, regularly plugging in the hybrid’s battery to maximize its electric range will drastically reduce visits to the gas station.

How it compares

The Panamera Turbo S e-Hybrid isn’t exactly swimming in a sea of direct competitors, but comparing it to similar vehicles from other manufacturers puts its efficiency into perspective. For example, the BMW M5 CS, a high-performance sedan with a purely gasoline-powered engine, achieves an EPA-estimated 17 MPG combined. The Mercedes-AMG GT 63 S 4-Door Coupe, another contender in the high-performance sedan segment, manages 16 MPG combined. Even Porsche’s own Cayenne Turbo S e-Hybrid SUV, sharing a similar powertrain, achieves slightly worse numbers due to its larger size and increased weight: 18 MPG combined.

Tips to maximize efficiency

Take advantage of the hybrid system’s capabilities. Fully charge the battery whenever possible and prioritize electric-only driving for short trips around town. This reduces your reliance on the gasoline engine and minimizes fuel consumption.

Drive smoothly and avoid hard acceleration when possible. Quick bursts of speed drain the battery quickly and increase fuel consumption. Gentle acceleration and maintaining a consistent speed help to conserve energy.

Use the Panamera’s various driving modes effectively. Select “Hybrid Auto” for the most balanced approach, or choose “E-Power” for pure electric driving. Experiment with “E-Hold” or “E-Charge” to reserve and/or recharge the battery.

Regular maintenance is important for optimal efficiency. Ensure that tires are properly inflated, keep up with scheduled service intervals, and address any mechanical issues promptly. A well-maintained vehicle operates more efficiently.

Consider using the regenerative braking feature. This system captures energy during deceleration and braking, which helps to recharge the battery and reduce wear on the brakes. It also helps maximize range for driving around town.
