20 MPG combined isn’t going to win any awards, but it’s the number attached to the 2022 Porsche 911 Carrera S, and it’s a figure that rarely affects the purchase decision. The 911 Carrera S isn’t about maximizing every last drop of fuel; it’s about delivering a visceral driving experience packaged in one of the most recognizable sports car silhouettes in automotive history. This isn’t a car for budget-conscious commuters; it’s for those who prioritize performance, driving pleasure, and heritage over fuel savings. The people buying this car are enthusiasts who understand the balance between power and efficiency, and they’re willing to accept this tradeoff.

City and highway performance

The EPA estimates for the 2022 Porsche 911 Carrera S with its 3.0L turbocharged flat-six and eight-speed PDK transmission come in at 18 MPG in the city and 23 MPG on the highway. The lower city MPG reflects the nature of stop-and-go driving, where the engine works harder and the turbochargers are constantly spooling and unspooling. The highway figure is a bit more optimistic assuming consistent speed and minimal acceleration. Real-world experience can vary significantly based on driving style and traffic conditions, underscoring that these figures are merely guidelines for comparison.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Porsche 911 Carrera S to be $2,900. This figure is based on driving 15,000 miles per year and using the national average fuel price for premium gasoline, which is the only acceptable fuel for this high-performance engine. Fluctuations in gasoline prices can significantly impact this cost, as can your driving habits. Consider this number a baseline; your actual spending may be higher or lower depending on how and where you drive.

Real-world expectations

The EPA figures provide a standardized benchmark, but most 911 Carrera S owners find that their real-world fuel economy often deviates from these estimates. Drivers with a heavier foot or those who frequently engage in spirited driving may see numbers closer to the low teens, particularly in city driving. Conversely, those who prioritize smooth acceleration and consistent highway speeds can potentially achieve or even surpass the EPA highway figure. This variance highlights the impact of driver behavior on fuel consumption in a performance car as responsive as the 911.

How it compares

Compared to its competitors, the 2022 Porsche 911 Carrera S’s fuel economy occupies a specific niche. The BMW M4 Competition, with its 3.0L inline-six, delivers a similar performance profile but slightly better EPA estimates, hovering around 16 MPG city and 23 MPG highway. The Mercedes-AMG C63 S, boasting a more fuel-hungry 4.0L V8, posts even lower numbers that can easily be below 16 MPG combined in normal driving. Even all Porsche fuel economy data shows how the pursuit of more power typically means a tradeoff in fuel efficiency. The fact that the 911 achieves similar highway MPG as the M4 despite producing similar power reflects Porsche’s commitment to engineering efficiency into its performance vehicles. This is why buyers who want a balance of both will often look at the 911 MPG across all years.

Tips to maximize efficiency

Despite its performance intentions, you can employ several strategies to improve the fuel economy of your 2022 Porsche 911 Carrera S. Use smooth acceleration and avoid aggressive bursts of speed. The turbocharged engine responds well to gentle inputs, allowing you to maintain momentum without burning fuel.

Use the Porsche’s driving modes effectively. Selecting “Normal” or “Eco” mode will remap the throttle response and shift points to prioritize efficiency over outright performance. The temptation to leave it in “Sport” mode is strong, but mindful use of these more conservative settings can yield noticeable fuel savings.

Ensure proper tire inflation and regular maintenance. Underinflated tires increase rolling resistance, forcing the engine to work harder. Similarly, a well-maintained engine runs more efficiently. Adhering to Porsche’s recommended service schedule is essential for optimal fuel economy and performance.

Minimize unnecessary weight. Removing excess cargo from the vehicle reduces the load on the engine, improving fuel efficiency. The 911 isn’t known for its cargo capacity, but eliminating clutter in the front trunk and passenger compartment can contribute to incremental gains.
