The 2019 Porsche Panamera 4 Executive 3.0L’s combined fuel economy of 22 MPG won’t impress hypermilers, but that’s not its purpose. This is a stretched, luxurious grand tourer with all-wheel drive and ample power, designed for covering long distances in comfort and at speed. Fuel efficiency is a consideration, but performance and prestige are more important for Panamera buyers.

City and highway performance

The EPA estimates the Panamera 4 Executive gets 19 MPG in city driving. Urban stop-and-go traffic impacts fuel economy, and the car’s weight and all-wheel-drive system contribute to the lower number. On the open road, the Panamera performs better, achieving 26 MPG on the highway. The engine cruises efficiently at higher speeds, aided by the smooth-shifting eight-speed automatic transmission (AM-S8) and its efficient design.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Porsche Panamera 4 Executive 3.0L at $2,650. This is based on driving 15,000 miles per year, with a mix of city and highway driving, using national average fuel prices. Actual fuel costs will vary depending on driving habits, local fuel prices, and fuel grade. Porsche recommends premium fuel, but some owners may experiment with mid-grade gas at their own risk.

Real-world expectations

EPA estimates provide a general idea, but real-world fuel economy can change. Aggressive driving, frequent hard acceleration, and mostly city driving will likely result in lower MPG. Careful driving, smooth acceleration, and more highway miles could improve fuel economy beyond the EPA estimates. Owners seeking better efficiency might consider using the car’s “Normal” or “Eco” driving modes to optimize fuel consumption.

How it compares

The Panamera 4 Executive’s fuel economy is similar to other high-performance luxury sedans. The Mercedes-Benz S450 4MATIC, for example, is rated at 19 MPG city and 28 MPG highway, a slight advantage on the highway. The Audi A8 55 TFSI Quattro achieves similar numbers, at 19 MPG city and 27 MPG highway. These differences are small for buyers in this segment, where performance and features often matter more than slight MPG differences. For those looking at the Panamera range, it’s worth exploring PANAMERA MPG across all years to compare different powertrains and their respective fuel consumption figures. And the all Porsche fuel economy data shows how important it is to consider the Porsche car that is right for your situation.

Tips to maximize efficiency

Drive smoothly. The Panamera 4 Executive has plenty of power, but fast acceleration and hard braking use more fuel. Gentle acceleration and anticipating traffic will improve your MPG.

Maintain proper tire pressure. Underinflated tires increase rolling resistance, which reduces fuel economy. Regularly check the recommended tire pressure, usually on a sticker inside the driver’s side doorjamb.

Reduce extra weight. Carrying too much cargo in the trunk adds weight, which hurts fuel efficiency. Remove unnecessary items to improve gas mileage.

Use the car’s driving modes. The Panamera has “Normal” and “Eco” modes, which change engine and transmission settings for better fuel efficiency. Select the right mode for the conditions to save fuel when performance isn’t a priority.

If fuel economy is important, even within the Porsche lineup, consider a hybrid Panamera model. These offer better MPG without sacrificing performance and luxury that Porsche buyers expect.
