19 MPG combined for the 2025 Porsche Macan GTS isn’t about saving the planet; it’s about unapologetic performance and the visceral thrill of a 2.9-liter twin-turbocharged V6 screaming towards its redline. This isn’t a family hauler where fuel economy is a primary decision factor. It is, unequivocally, a sports car in SUV clothing, designed for drivers who prioritize engaging dynamics, pinpoint steering, and the intoxicating rush of unadulterated power delivery. The Macan GTS exists to blur the lines between a high-performance sedan and a practical crossover, and its efficiency figures reflect that ambitious, driver-centric mission. These 19 combined miles per gallon are the cost of admission to one of the most involving driving experiences in the segment, a trade-off readily accepted by its target audience.

City and highway performance

The EPA’s 17 MPG in the city for the Macan GTS is a realistic reflection of its character. Frequent stop-and-go driving, coupled with the temptation to exploit the twin-turbo V6’s instantaneous torque, inevitably impacts efficiency. This is a powertrain that begs to be revved, and those quick bursts of acceleration, characteristic of urban driving, consume fuel rapidly. Conversely, the 22 MPG highway rating provides a glimpse into the Macan GTS’s ability to settle down on longer journeys. The 8-speed Porsche Doppelkupplung (PDK) automatic transmission adeptly manages gear changes, keeping engine RPMs lower at cruising speeds. While 22 MPG on the open road won’t win any efficiency awards against an economy car, it’s a respectable figure for a vehicle capable of sprinting to 60 mph in under 4.1 seconds. Most drivers of the Macan GTS, however, buy it not for its highway composure but for the sheer dominance it exhibits during spirited driving, where fuel consumption tends to be a secondary consideration.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,050 for the 2025 Porsche Macan GTS 2.9L 6-cyl. This figure is derived from an assumption of 15,000 miles driven per year, split between city and highway conditions, and based on national average fuel prices, which for premium octane are naturally higher than regular unleaded. For the typical Macan GTS owner, this $3,050 annual expenditure is a known quantity, a line item in a budget already accustomed to the premium associated with owning and maintaining a high-performance luxury vehicle. It’s part of the cost of ownership, alongside insurance, maintenance, and the initial sticker price. This isn’t a surprise or a deterrent; it’s simply the financial acknowledgment of the GTS badge and what it represents.

Real-world expectations

Expect your actual fuel economy in the Macan GTS to vary, often significantly, from the EPA numbers. The character of this vehicle, and the driving behavior it encourages, means that the average driver will likely see figures closer to the city rating, or even below it, during enthusiastic excursions. Pushing the 2.9L V6 through its rev range, using Sport or Sport Plus modes, and engaging in spirited driving on winding roads will inevitably result in single-digit MPG readings. Conversely, a disciplined driver committed to eco-minded techniques on extended highway trips might nudge closer to, or even slightly exceed, the 22 MPG highway figure. However, restraint is antithetical to the GTS experience. The true driver of a Macan GTS revels in its power and handling, understanding that fuel consumption is a direct consequence of the driving joy it delivers. Owners prioritize the smile it puts on their face over the numbers at the pump. More information on all Porsche fuel economy data is available on our site, covering the entire lineup.

How it compares

The 2025 Macan GTS sits in a competitive space, but its comparison often revolves around performance more than raw efficiency. A direct rival like the Mercedes-AMG GLC 43 Coupe, with its 3.0L twin-turbo V6, offers a very similar 19 MPG combined (18 City / 24 Highway). The BMW X3 M40i, featuring a 3.0L turbo inline-six, boasts a slightly better 23 MPG combined (21 City / 26 Highway), appealing to a similar buyer looking for a blend of performance and practicality, albeit with a slightly different driving character. On the other hand, the Audi SQ5, with its 3.0L turbo V6, achieves 21 MPG combined (19 City / 24 Highway), representing another strong contender in the segment. These comparisons illustrate that the Macan GTS’s fuel economy is entirely in line with its direct, high-performance segment peers. Buyers considering this echelon of compact luxury SUVs are cross-shopping based on brand prestige, driving dynamics, interior refinement, and outright speed rather than a few miles per gallon difference. They choose the Macan GTS for its unique Porsche DNA, its telepathic steering, and its unfiltered connection to the road, attributes that tend to outweigh purely economic considerations.

Tips to maximize efficiency

While efficiency isn’t the primary goal, even a Macan GTS owner can employ strategies to moderately improve fuel economy when not fully exploiting its capabilities. Smooth acceleration and braking, avoiding abrupt inputs, can notably reduce fuel consumption in city driving.

Engage the “Normal” drive mode, rather than Sport or Sport Plus, during commutes or long highway stretches. This mode optimizes transmission shift points and engine mapping for efficiency, rather than aggressive performance.

Regularly check and maintain correct tire pressures. Underinflated tires increase rolling resistance, forcing the engine to work harder and directly impacting fuel economy.

Use the automatic start/stop system. While some drivers find it intrusive, this feature, when active, can save a measurable amount of fuel during extended idling in traffic by shutting off the engine.

Plan routes to minimize unnecessary idling and avoid heavy traffic whenever possible. The Macan GTS is less efficient at a standstill than when it’s moving, even at lower speeds.
