The 2016 Porsche Panamera Turbo S Executive 4.8L 8-cyl gets 18 MPG combined, a figure that likely won’t surprise its target demographic. This isn’t a car bought for saving fuel, it’s a statement of performance, luxury, and exclusivity, where fuel economy is a secondary consideration. The Turbo S Executive caters to those who demand maximum power and space, and are willing to pay the price at the dealership and at the gas pump.

City and highway performance

The EPA estimates 15 MPG in the city and 24 MPG on the highway, which shows the Panamera Turbo S Executive’s thirst for fuel. Stop-and-go traffic punishes the 4.8-liter twin-turbo V8, requiring frequent refills. Achieving the 24 MPG highway figure requires actively maintaining a gentle driving style on the open road. The temptation to use the engine’s significant power is ever-present, and quick bursts of acceleration will reduce any fuel savings. The 7-speed automatic transmission (AM-S7) generally does a good job of optimizing fuel economy, but its priority is performance, quick gear changes over efficiency.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Porsche Panamera Turbo S Executive at $3,200. This 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 vehicle uses gasoline priced at the national average. For Panamera Turbo S Executive owners, this is more of a theoretical calculation than a practical concern. They likely drive more miles than average and, given the car’s performance, probably spend more time with their foot firmly on the accelerator.

Real-world expectations

While the EPA estimates offer a baseline, real-world fuel economy for the Panamera Turbo S Executive can vary. Aggressive driving, frequent use of the Sport or Sport Plus modes, and extended periods of idling will all significantly decrease fuel efficiency. A driver who adopts a more relaxed driving style and uses cruise control on the highway might see numbers closer to the EPA estimates. The Panamera Turbo S Executive’s fuel economy is heavily influenced by the driver’s habits and the driving conditions. Do not expect to duplicate the estimate regularly.

How it compares

Compared to other high-performance luxury sedans, the 2016 Panamera Turbo S Executive’s fuel economy is in line with its competitors. The Mercedes-AMG S63 Sedan, with its twin-turbo V8, achieves a similar 16 MPG combined. The BMW M760i xDrive, packing a V12 engine, also falls in the same range, typically earning around 15 MPG combined. Porsche’s own Cayenne Turbo S, sharing a similar engine, delivers comparable fuel economy. Those seeking better fuel efficiency within the Porsche lineup can explore other Panamera models, and might want to review PANAMERA MPG across all years, or consider other brands entirely. The specific buyer of this trim is unlikely to compromise on power for the sake of economy.

Tips to maximize efficiency

Avoid aggressive acceleration: The Panamera Turbo S Executive’s twin-turbo V8 is responsive, but each hard acceleration extracts a significant fuel penalty. Smooth and gradual acceleration minimizes fuel consumption, especially in city driving, and it will help avoid attracting unwanted attention.

Proper tire inflation: Maintaining the correct tire pressure reduces rolling resistance, leading to improved fuel economy. Check your tire pressures regularly, when the tires are cold, and adjust them to the recommended levels specified in the owner’s manual. Low tire pressure hurts fuel economy, and it can negatively affect handling.

Minimize idling: Idling consumes fuel without covering any distance. If you anticipate being stationary for more than a minute, it’s generally more efficient to switch off the engine. Modern engines are designed to restart quickly and reliably, minimizing any inconvenience. This is true with vehicles fitted with auto start-stop.

Plan routes strategically: Avoiding congested areas and opting for routes with fewer stop-and-go situations can significantly improve fuel economy. Use navigation systems and real-time traffic updates to find the most efficient path, potentially shaving miles off your journey.

Consider driving mode: The Sport and Sport Plus modes unlock the Panamera Turbo S Executive’s full performance potential, but they also increase fuel consumption. Opting for the standard or Eco mode, when appropriate, can help to maximize fuel efficiency. See all Porsche fuel economy data to understand how the entire range performs.
