19 MPG combined is what drivers get when they want the 2016 Porsche Panamera GTS experience. This figure will immediately disqualify this powerful four-door coupe for some. But for those who prioritize a visceral driving experience, a sonorous V8 soundtrack, and the exclusivity that comes with the Porsche crest, it simply becomes the cost of admission. This isn’t a machine for saving fuel; it’s for devouring asphalt.

City and highway performance

The split between city and highway fuel economy highlights the Panamera GTS’s duality. The EPA estimates 16 MPG in the city, which reflects the engine constantly cycling through stop-and-go traffic, and the need to overcome the car’s weight. Even Porsche’s engineering can’t fully negate physics. On the open road, the story improves, rising to 24 MPG. This is where the tall gearing of its 7-speed PDK automatic transmission comes into play, allowing the engine to run at lower RPMs and demonstrating relatively acceptable fuel consumption. Even on the highway, a heavy foot will quickly send those numbers plummeting as the temptation to unleash the 440 horsepower becomes irresistible.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2016 Porsche Panamera GTS will be $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, using national average fuel prices. It’s a sobering number that should be considered alongside the Panamera’s purchase price and maintenance costs, representing a significant ongoing expense. Owners should be aware that premium fuel is recommended, further adding to the financial burden. This figure offers a standardized way to compare running costs against other vehicles, acknowledging that individual driving habits will heavily influence actual fuel expenditure.

Real-world expectations

Forget the EPA numbers; your mileage will vary. A lead foot and a penchant for Sport Plus mode will turn that 19 MPG combined into a distant aspiration. But, a disciplined driver who spends most of their time on the highway and resists the urge to overtake every car in sight might see slightly better figures. Consider the EPA rating a best-case scenario and plan accordingly. The type of driving, road conditions, and even tire pressures can all have a measurable impact on the fuel consumption of the Panamera GTS. The allure of the Porsche driving experience often outweighs the concern for fuel economy for most owners.

How it compares

Compared to its competitors, the 2016 Panamera GTS’s fuel economy is firmly in the middle of the pack. A BMW M6 Gran Coupe, with its similarly powerful V8, delivers roughly the same combined MPG. Audi’s RS7, another performance-oriented four-door, lands within a similar range too. A Mercedes-AMG CLS63 S exhibits comparable fuel thirst. Where the Panamera GTS differs is in the unique blend of driving dynamics, Porsche heritage, and, some would argue, superior styling, not in fuel efficiency. Those considering a Panamera GTS are typically less concerned with squeezing out an extra mile per gallon and more focused on the overall driving experience which often surpasses competitors.

Tips to maximize efficiency

Resist the calling of Sport and Sport Plus driving modes as often as possible. While these modes sharpen throttle response and hold gears longer, they also significantly increase fuel consumption. Use the “Normal” mode for everyday driving where performance isn’t important.

Maintain optimal tire pressure. Properly inflated tires reduce rolling resistance, leading to improved fuel economy. Check your tire pressure regularly and inflate them to the recommended levels found on the driver’s side doorjamb. This is simple and immediately effective.

Avoid unnecessary idling. If you’re stopped for more than a minute, turn off the engine. Modern engines are designed to restart quickly and efficiently, and idling burns fuel without covering any distance.

Plan your routes to avoid stop-and-go traffic whenever possible. Constant acceleration and braking are fuel killers. A route with fewer stops and smoother traffic flow will significantly improve your fuel economy.

Consider a gentle driving style. Smooth acceleration and gradual braking can conserve fuel. The Panamera GTS begs to be driven hard, but moderation occasionally pays dividends at the pump. See all Porsche fuel economy data for context.
