19 MPG combined isn’t going to win any fuel-sipping awards, but let’s be realistic: the 2021 Porsche Panamera Turbo S e-Hybrid Sport Turismo isn’t trying to be a Prius. This is a nearly 700 horsepower, all-wheel-drive rocket ship disguised as a semi-practical wagon. Fuel economy is a consideration, sure, but it ranks far below factors like blistering acceleration, corner-carving prowess, and the ability to haul the kids and dogs in reasonable comfort. The typical Panamera Turbo S e-Hybrid ST buyer isn’t cross-shopping against hybrid SUVs; they’re looking at how many seconds they can shave off their commute while enjoying heated leather seats.

City and highway performance

The EPA estimates the Panamera Turbo S e-Hybrid Sport Turismo at 18 MPG in the city and 22 MPG on the highway. While these numbers won’t make headlines, they’re indicative of the vehicle’s personality: capable of impressive bursts of efficiency, but ultimately prioritizing performance. In stop-and-go traffic, the electric motor can shoulder much of the burden, temporarily mimicking a much more frugal machine. On the open road, however, the twin-turbo V8 is eager to stretch its legs, and the MPG reflects that eagerness. This is a car that rewards spirited driving, and the fuel gauge will certainly acknowledge that.

Annual fuel cost

According to the EPA, you can expect to spend approximately $3,050 per year on fuel for the 2021 Porsche Panamera Turbo S e-Hybrid Sport Turismo. This figure is based on driving 15,000 miles per year, with fuel prices reflecting national averages, and a specified percentage of city versus highway driving. While considerably higher than a hybrid sedan, it represents the cost of entry into a very exclusive club of performance wagons. Remember this a national average, so your cost may be higher or lower based on where in the country you live or how frequently you drive.

Real-world expectations

The EPA estimates are a good starting point, but real-world fuel economy can vary significantly based on driving style, traffic conditions, and even the season. Drivers who frequently use the full potential of the Turbo S e-Hybrid’s powertrain will likely see fuel economy figures below the EPA estimates. Conversely, those who prioritize electric-only operation and drive conservatively may achieve slightly better results. Keep in mind that the electric driving range is limited, so longer trips will heavily rely on the gasoline engine. Cold weather and frequent use of climate control will also impact fuel efficiency.

How it compares

Compared to its direct competitors, the Panamera Turbo S e-Hybrid ST’s fuel economy is predictably mid-pack. The Mercedes-AMG E63 S Wagon, for example, is rated at 16 MPG combined. The Audi RS6 Avant, another performance wagon contender, posts a similar 17 MPG combined. The Porsche gives back some fuel efficiency, but more than compensate with raw power and hybrid assistance. If absolute fuel savings are important, a buyer might consider the standard Panamera 4 e-Hybrid, which delivers significantly higher fuel economy but sacrifices considerable performance.

Tips to maximize efficiency

Use the E-Power mode. The Panamera Turbo S e-Hybrid ST offers an electric-only driving mode that can be extremely useful for short trips around town. Making the most of this will reduce your petrol consumption and increase overall mileage. Take advantage of regenerative braking to recharge the battery and reduce wear on the conventional brake pads. These hybrid-specific features can easily add several MPG when mastered.

Drive smoothly. A smooth, consistent driving style can significantly impact fuel economy. Avoid aggressive acceleration and hard braking, as these actions waste fuel and reduce battery range. Anticipate traffic flow and maintain a steady speed whenever possible to maximize the electric drive system’s efficiency.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which forces the engine to work harder and reduces fuel economy. Check your tire pressure regularly and inflate to the recommended level, which can be found on a sticker inside the driver’s side door or in the owner’s manual.

Keep the vehicle properly maintained. Regularly scheduled maintenance, such as oil changes and air filter replacements, can help ensure that the engine is running efficiently. A well-maintained engine consumes less fuel and produces fewer emissions.

Reduce weight and drag. Avoid carrying unnecessary weight in the vehicle, as this can reduce fuel economy. Remove roof racks or cargo carriers when they’re not in use because these items increase aerodynamic drag. Every little bit helps when trying to squeeze the most out of each litre.
