19 MPG combined might surprise some, considering the popularity of hybrid sedans and electric vehicles. But the 2022 Porsche Panamera 4S Executive isn’t trying to be an economy car. It blends sports car performance with limousine-like comfort and space, and this particular model is for a very specific owner: someone who enjoys being driven as much as driving themselves. These buyers accept the higher fuel cost for the car’s unique abilities.

City and highway performance

The Panamera 4S Executive, with its 2.9-liter twin-turbocharged V6, gets 17 MPG in the city and 23 MPG on the highway. The city number reflects typical urban commutes, where the engine’s full potential often isn’t used. The highway figure better represents relaxed cruising, which this extended-wheelbase Panamera does well. The eight-speed automatic transmission (AM-S8) helps keep the engine at its most efficient RPM when it can. However, the tempting power is always a downshift away, and frequent turbocharger use will affect fuel consumption. Knowing the PANAMERA MPG across all years gives context to this model’s place in the lineup.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Porsche Panamera 4S Executive will be $3,050. This is based on driving 15,000 miles per year, with 45% in the city and 55% on the highway, using national average fuel prices. It’s a significant expense that potential buyers should consider. However, for those considering a Panamera 4S Executive, fuel costs are often less important than the experience and prestige the car offers.

Real-world expectations

EPA estimates are a useful benchmark, but real-world fuel economy can change a lot based on driving style, traffic, and even fuel grade. Hard acceleration, frequent hard braking, and long idling will all reduce MPG. The Panamera’s engine is optimized for premium gasoline, so using lower-grade fuel may also slightly reduce fuel efficiency and potentially affect performance. Drivers who want to save fuel should drive smoothly, anticipate what’s coming, and avoid unnecessary idling.

How it compares

The Panamera 4S Executive’s fuel economy is in the middle of its luxury performance sedan class. The Mercedes-Benz S500 delivers 21 MPG combined and offers similar luxury but focuses more on comfort than performance. The Audi RS7 gets around 18 MPG combined, trading fuel economy for much more horsepower and driving excitement. Those wanting better fuel economy might consider the BMW 745e plug-in hybrid, which gets better numbers when using its electric range, though it has less cargo space and less sporty handling. Buyers will cross-shop these flagship sedans, weighing fuel costs against other benefits.

Tips to maximize efficiency

The Panamera’s driving mode selector is the first way to fight poor fuel economy. The “Normal” or “Eco” modes change throttle response and shift points to prioritize fuel efficiency. Using these modes during regular commutes can noticeably improve your MPG without losing too much performance.

Tire pressure is important for fuel efficiency. Make sure your tires are inflated to the manufacturer’s recommended pressure, which is on the driver’s side doorjamb. Underinflated tires create more rolling resistance, making the engine work harder and use more fuel. Check and keep proper tire pressure regularly.

The Panamera 4S Executive is a heavy car, and extra weight in the trunk or back seats hurts fuel economy. Remove anything you don’t need to lighten the load and improve MPG; it will help. A lighter car accelerates easier.

Anticipate traffic and avoid sudden acceleration and braking. Smooth, consistent driving is key to saving fuel in any vehicle, including the Panamera 4S Executive. By predicting traffic and keeping a safe distance, you can greatly reduce fuel use.

Avoid idling for long periods whenever possible. If you’ll be stopped for more than a minute, turn off the engine. Modern engines restart quickly and efficiently, and reducing idling time can save fuel. This is especially important in cities, where idling is common.
